Ross rifle in the Royal Canadian Regiment Museum in London, Ontario

The Ross rifle was a straight-pull bolt action .303 inch-calibre rifle produced in Canada from 1903 until 1918, which has the dubious distinction of quite possibly being the most despised rifle in Canadian military history.

While the Ross Mk.II (or "model 1905") was highly successful in target shooting before WWI, the close chamber tolerances, lack of primary extraction and overall length made the Mk.III (or "1910") Ross rifle miserably unsuitable for the conditions of trench warfare and the often dubious quality ammunition issued.

By 1916, the rifle had been withdrawn from front line service, but continued to be used by many snipers of the Canadian Expeditionary Force until the end of the war due to its exceptional accuracy.

The Ross Rifle Co. made sporting rifles from early in its production, most notably chambered in .280 Ross, introduced in 1907. This cartridge is recorded as the first to achieve over 3000 feet per second velocity, and the cartridge acquired a very considerable international reputation among target shooters and hunters.

	The Ross rifle lived up to its reputation as a target rifle, accurate and effective in the hands of a marksman; but unfortunately it also lived up to and enhanced its record for jamming, and a rifle which jammed in such circumstance was damned.
— Fortescue Duguid

History

During the Second Boer War, a minor diplomatic fight broke out between Canada and the United Kingdom, after the latter refused to license the Lee–Enfield SMLE design for production in Canada. Sir Charles Ross offered his newly designed straight-pull rifle as a replacement. Ross was well connected in Canadian society and eventually landed his first contract in 1903 for 12,000 Mark I Ross rifles.

In this design, the bolt locking lugs are mounted on a screw, and when the operating handle is pulled or pushed, the screw automatically turns to rotate the locking lugs into place in the action receiver. The design is generally similar to that used on most artillery pieces. Unlike the more common bolt actions found in the Mauser and Lee–Enfield, the Ross action did not need to have the handle rotated a quarter turn before the bolt was pulled back, and this feature theoretically offered a higher rate of fire. In addition, unlike the Lee–Enfield, the Ross rifle could be disassembled more quickly without special tools, though it was 1 pound heavier.

Service

The first 1,000 rifles were given to the Royal Northwest Mounted Police (RNWMP) for testing. Routine inspection before operational testing found 113 defects bad enough to warrant rejection. One of these was a poorly designed bolt lock that enabled the bolt to fall right out of the rifle. Another was poorly tempered component springs that were described as being as "soft as copper". The RNWMP promptly reverted to their Model 1894 Winchesters and Lee–Metfords in 1906.

Mechanism comparison between Ross Mk III (1910) and Mk II** (1907)

The Ross rifle was modified to correct these faults and became the Mark II Ross (Model 05 (1905)). In 1907, the Mk II was modified to handle the higher pressure of newly designed .280 Ross, this variant was called Mk II**. The Model 10 (1910) was a completely new design, made to correct the shortcomings of the 1905. None of the major parts are interchangeable between the 1905 and the 1910 models. Although the British were now encouraging standardization across the Empire on the Lee–Enfield, Canada stayed with the Ross. The Model 10 was the standard infantry weapon of the First Canadian Contingent of the Canadian Expeditionary Force when it first arrived in France in February 1915.

	During the repeated attacks, the Canadians became frustrated with the failure of their Ross rifles. They jammed after firing, at most, three rounds. To force the bolt open, a man had to lie down and take his heel to it.
— Arthur Bishop

The lethal shortcomings of the rifle were made apparent during the Second Battle of Ypres in April 1915. The rifle showed poor tolerance for dirt when used in field conditions, particularly the screw threads operating the bolt lugs, jamming the weapon open or closed. Another part of the jamming problem came from the bolt's outer face hitting the bolt stop, then deforming the thread shape. The bolt could also be disassembled for routine cleaning and inadvertently reassembled in a manner that would fail to lock but still allow a round to be fired, leading to serious injury or death of the operator as the bolt flew back into his face. Another well-known deficiency was the tendency for the bayonet to fall off the damn rifle when the weapon was fired. Many Canadians of the First Contingent (now renamed the 1st Canadian Division) at Ypres retrieved Lee–Enfields from British casualties to replace their Ross rifles. Lieutenant Chris Scriven of the 10th Battalion, CEF, commented that it sometimes took five men just to keep one rifle firing.

	It is not surprising that many of the 1st Division armed themselves with with Lee-Enfield rifles acquired from British casualties.
— G.W.L. Nicholson

Complaints rapidly reached the rifle's chief sponsor, the Canadian Minister of Militia and Defence Sam Hughes. He nevertheless continued to believe in its strengths despite the professional opinion of Sir Edwin Alderson, the British Army officer who was commander of the First Canadian Division. The rifle became an element in political issues within Canada and between Canada and the British. Hughes responded to Alderson's criticism by accusing Alderson of ignorance and copied the letter to many officers in the corps. The effect was to undermine confidence in Alderson and the rifle. Hughes also made accusations that Canadian officers were induced to produce adverse reports on the rifle. After the reports on the rifle were published through the Ottawa Citizen, and it became clear that his claims in the Commons that all faults had been cured were false, Hughes' defence of the rifle could no longer be supported by the Prime Minister.

In particular, the Ross was more accurate at long range than the SMLE, and this potentially overcame the serious problem British and Canadian troops had faced during the Boer War, with the accurate long-range fire from the 7 mm Mauser.

In all, approximately 420,000 Ross service rifles were produced, 342,040 of which were purchased by the British.

Note: In the summer of 1910, the last 4000 of Rifle, Ross Mk II with Sight, Ross Mk III were produced with an improved extractor introduced with the Rifle, Ross Mk II**. These were designated Rifle, Ross Mk II⁴*. Almost immediately after production, all 4000 were converted to Rifle, Ross Mk II³* by fitting them with the Sight, Sutherland Mk II. The above chart is left as presented by the Army Historical Branch rather than altered to include this additional information.

Replacement

Canadians retained the Ross even as additional contingents arrived in France. By the time of the Somme battles of July 1916, Sir Douglas Haig, the new Commander-in-Chief of the British Expeditionary Force, had ordered the replacement of all Ross rifles in the three Canadian Divisions by the Lee–Enfield, which was finally available in quantity. Hughes refused to accept that there were problems with the Ross, and it took the intervention of many influential people to persuade him otherwise. In November 1916, Hughes resigned after Sir Robert Borden's decision to appoint a Minister of Overseas Forces. Ross rifles were then used in training roles, both in Canada and the UK, to free up more Lee–Enfields for the front. After the United States entered the war in 1917, Ross rifles were shipped to the U.S. for the same reasons, freeing up supplies of the M1903 Springfield rifle. Hughes' reputation was inevitably tarnished, but Sir Charles Ross had already made a considerable fortune from his rifle design and manufacturing contracts despite its reputation.

At around same time, the Dominion Rifle Factory (Quebec City) converted a number of Rosses into the Huot automatic rifle, under the guidance of a designer named Joseph Alphonse Huot. It was an effective design, feeding from a drum magazine, and cheaper than a Lewis Gun. Unfortunately, despite successful trials, the war ended before it could be entered into service.

Military variants

Rifle, Ross Mk I This was the first production military model Ross Rifle. The first 500 (made for Fish & Game) were fitted with the full-length folding Sight, Ross Mk I. Before any were deliverd, this was replaced with the a shorter version graduated to only 2200 yards rather than 2500 yards. Years later, this sight would be designated Sight, Ross Mk I*. Later, many would have this replaced with the Sight, Ross Mk II, a curved sliding type. The barrel was 28 in long, and the fore-stock ended 4in short of the muzzle. The front band had a bayonet lug. The safety was operated by a square sliding button on the rear of the bolt handle. The magazine cut-off was on the lower right of the magazine protruding through the stock, and pressing it down engaged the cut-off. The magazine cut-off release was inside the front of the tigger guard, and depressing it would disengage the cut-off. A large lever was on the right side which was used to depress the magazine follower for "dump loading" all five rounds at once. There was a sliding trap in the butt-stock for cleaning tools. A total of 10,500 were manufactured. A number of the original 500 were repurposed as training rifles and fitted with longer front barrel bands used on later production Rifle, Ross Mk II. This was done so they could more easily endure the stress of constant bayonet practice.

Carbine, Ross Mk I The RNWMP purchased 1000 shorter versions of the Rifle, Ross Mk I. The main difference was the barrel lenght of 26in. The full stock of the rifle was retained, and the barrel projected only 2 inches past the fore-stock. As presented for inspection, the carbines used the shorter version of the Sight, Ross Mk I. However, at the inspector's request, the weapons were delivered fitted with Sight, Ross Mk II.

Rifle, Ross Mk I* This designation was (according to available sources) a 1909 re-designation of those Rifles, Ross Mk I that had been fitted with the Sight, Ross Mk II.

Rifle, Ross Mk II / Rifle, Ross Mk II with Sight, Ross Mk II After various complaints, the weapon was re-designed to address the issues. The most noticable change was the replacement of the side-mounted magazine cut-off control and trigger-guard mounted cut-off release with a single hook shaped control inside the front trigger guard that performed both functions. The safety was similar, but the slideer was moved by pushing a round button. Changes were introduced in production without change in designation until the introduction of the Sight, Ross Mk III when the nomenclature of the earlier rifles was expanded to Rifle, Ross Mk II with Sight, Ross Mk II.

Rifle, Ross Mk II with Sight, Ross Mk III Sight, Ross Mk II proved more fragile than desired, and it was replaced with a simpler version. The offical nomenclature for this model was Rifle, Ross Mk II with Sight, Ross Mk III. Further improvements were incorporated in this model without bothering to change the designation.

Rifle, Ross Mk II* In early 1909 it was decided to adapt the Rifle Ross Mk II with Sight, Ross Mk II for cadet use, doing full maintenance and upgrading components to later production changes. 5,800 weapons were so converted from late 1909 to mid 1910. The weapons were designated Rifle, Ross Mk II*. This designation identified specific conversions of older weapons and did not reflect changes to new production.

Rifle, Ross Mk II** Development of this weapon began in the spring of 1908, and the planned designation was Rifle, Ross Mk III. This model was intended as a major improvement over the previous Rifle, Ross Mark II with Sight, Ross Mk III. The barrel length was extended to 30.5in, the rear hand-guard was simplified, the safety was replaced by a completely new flag-type safety, and the rear sight was changed to the third-party Sight, Sutherland Mk I. The magazine cut-off was dispensed with entirely. By the time it was ready to be produced in numbers, an even more radical design change was in the works to become the Mk III, and this model was desginated Rifle, Ross Mk II** instead.

Rifle, Ross Mk II³* This rifle was an adaptation of the Rifle, Ross Mk II to use the Sight, Sutherland Mk II. Some internal improvements were made as well. The original sliding button safety and the magazine cut-off were retained, along with the 28in barrel and the stylish older rear handguard. None of this model were newly manufactured. Instead, Rifle, Ross Mk II with Sight, Ross Mk III and the later Rifle, Ross Mk II⁴* were converted to this model.

Rifle, Ross Mk II⁴* This rifle was a simple upgrade of the last 4000 manufactured Rifle, Ross Mk II with Sight, Ross Mk III to include the new larger extractor introduced with the Rifle, Ross Mk II**. The 28 in barrel, stylish rear hand-guard, slidng button safety, and magazine cut-off were retained. They were completed in the early summer of 1910, then all 4000 were immediately converted into Rifle, Ross Mk II³*.

Rifle, Ross Mk II⁵* The last of the Mk II line would be produced using the Sight, Sutherland Mk I and simplified rear hand-guard of the Rifle, Ross Mk II**. The 28 in barrel, slidng button safety, and magazine cut-off were retained.

Rifle, Ross Mk III For all practical purposes, the Rifle, Ross Mk III was an entirely new design. It retained the 30.5in barrel and flag safety of the Rifle, Ross Mk II**. The internal double-stack magazine was replaced with an exposed single-stack magazine. The "dump loading" lever was gone, and a charger guide was added for loading with stripper clips. The magazine cut-off that lowered the magazine shell (and cartridges contained) was eliminated and replaced by one that restricted the rearward movement of the bolt forward of the cartridge base. The bolt-stop plunger was replaced by a flag lever with 3 positions (cut-off enabled, bolt release, cut-off disabled). The bolt was far sturdier and had locking threads instead of locking lugs. A new rear sight designated the Ross Battle Aperture was installed on the bridge of the reciever rather than on top of the barrel.

Rifle, Ross Mk IIIB The British government chose to purchased a version of the Rifle, Ross Mk III with a far simpler rear sight known as the War Office Pattern Sight.

Note: A Rifle, Ross Mk III* may have existed, employing a strengthened action, new front barrel band, and different front sight. One source mentioning it considers the designation dubious.

Military redesignations

In 1907, Rifle, Ross Mk II became Rifle, Ross Mk II with Sight, Ross Mk II and Rifle, Ross Mk II with Sight, Ross Mk III.

In 1912, all military variants were redesignated as follows:

Rifle, Ross Mk I and Rifle, Ross Mk I became Rifle, G.P. Ross (G.P. meaning general purpose).

Rifle, Ross Mk II with Sight, Ross Mk II and Rifle, Ross Mk II* became Rifle, Cadet, Ross.

Rifle, Ross Mk II with Sight, Ross Mk III became Rifle, Short, Ross Mk I.

Rifle, Ross Mk II³* and Rifle, Ross Mk II⁵* became Rifle, Short, Ross Mk II.

Rifle, Ross Mk II** became Rifle, Long, Ross Mk II.

Rifle, Ross Mk III became Rifle, Long, Ross Mk III.

In 1918, Rifle, G.P. Ross, Rifle, Cadet, Ross, Rifle, Short, Ross Mk I, and Rifle, Short, Ross Mk II became Rifle, Ross, .303", Cadet D.P. (D.P. meaning Drill Purpose).

Sniper rifles

Because of its long range accuracy, the Ross rifle continued in use among Allied snipers after it was withdrawn from normal front-line use in Europe. British snipers found the rifle accurate out to 600 yards and more, with only one inherent disadvantage: the Ross accepted only perfectly clean ammunition, totally free of mud and grit, or else it invariably jammed.

Two types of Mark III sniper rifles are identified by different telescopic sights. Five-hundred rifles were fitted with 5.2X Warner & Swasey Company Model 1913 prismatic telescopic sights manufactured in Cleveland, Ohio. Serial numbers for rifles manufactured in 1915 have a FK prefix; while those manufactured in 1917 have a LU prefix. Another 907 rifles were fitted with Winchester Repeating Arms Company A5 telescopic sights. Both telescopic sights were mounted offset so the iron sights were usable and the rifle could still be loaded from charging strips.

Sporting variant

Ross settled a gun factory in Hartford, Connecticut, with machinist J. A. Bennett, to produce a sporting rifle called Model 1897 Magazine Sporting Rifle a hinged hammer type rifle. By the same time, he made commercial agreement with famous gunmaker firm Charles William Lancaster, inventor of the oval bore, to be his exclusive UK agent.

• Caliber; .303 Brit.

Early 1900, he brought out the Model 1900 Sporter, still made in Bennett's factory. This action used a coil spring to activate the firing pin, instead of the hinged-hammer of the M1897. Very few of these sporting rifles are known to exist. The militarized Pattern 1900 was also the first to be offered for trial to Canada.

• Caliber; .303 British.

Following was Model 1903 Sporter some of these rifles were made in Hartford, Connecticut, but most (200 units, made from spare parts) were assembled at the brand new fabricating plant in Quebec City. Some of the Pattern 1903 Sporting Rifles were made in the .370 Express calibre, while some prototype chambered for .450/.500 Nitro is known to exist.

• Calibers; .303 Brit. (common), .256 Mannlicher (rare) and .370 Express (rare)

Some sporterised M1905 (Mk II) military rifles were made available to general public in 1906. This model was called Model M. In 1907, Ross brought out the Model E, his first entirely Canadian-made rifle, based on the 1905 military action, chambered for .303 British and .35 WCF. Following was Model R, which was a plain looking rifle, no checkering, in caliber .303 British only. In November 1906, Ross while in the process of developing a new and very powerful .280 caliber sporting cartridge, made some experimental tests with a necked-down version of the new 30-06 Springfield case which he called the .28-1906 (one rifle is known to exist). This led to the design of the .280 Ross. The new high-pressure round required some strengthening of the bolt and action receiver, but the rifle was otherwise only slightly different from the .303 Mark II. This design, called MK II**, was a transitional step between Mk II and Mk III actions.

• Calibers;

Model M (1905 Mk II action); .303 Brit

Model R (1905 Mk II action); .303 Brit.

Model E (1907 Mk II** action heavy barrel); .303 Brit., 35 WCF

Model 1907 'Scotch Deer Stalking Pattern'; .280 Ross

Model 1910 (Mk III) was made with a totally different bolt head; instead of having the solid bolt lugs travel in a vertical position and lock in a horizontal position, like for the Mk II and Mk II** (see illustration), Ross turned it 90 degrees so it travels in an horizontal position and locks vertically. Then, he used screw threads on the lugs outside which are locking into the matching threaded receiver. Some very scarce Mk II** with the same threaded lugs and receiver are known to exist. He also used the same shape of heavy barrel as used on the Mk II**. The M-10, in .280 Ross, is considered by many as being the finest rifle ever made by the Ross Rifle Co.

• Calibers

Model R-10; .303 Brit.

Model E-10; .303 Brit and .35 WCF

Model M-10; .280 Ross

1912 saw the introduction of the .22 rimfire sporting rifle. While using a simpler mechanism, it was still a straight-pull action. This model was very popular in Canada.

• Calibers; .22 Short, Long and Long Rifle.

Model 1912 Cadet Commercial.

Model 1912 Cadet "Leftover" (no serial numbers or any other markings)

The problems with the Ross in combat were that it was really a sporting design of rifle asked to do the work of a military rifle under trench warfare conditions. However, as a sporting rifle, the Ross became quite popular after the war. The new .280 Ross cartridge gained it a fine reputation for medium-sized game, and for a time after 1918 it was a fairly common rifle on safari. It also proved itself as being an outstanding Match Rifle, building a strong reputation for accuracy.

Match Rifles

Ross Mark II** Commercial Target Model in .303 British, with a 30.5 inch (770 mm) heavy barrel, was a real success in the Match Ranges from 1908 to 1913. This rifle was looking like the military Mk II**, using the same bolt, except having the sight bridge mounted on the receiver. A scarce Presentation Target Rifle was also available. Unlike its military counterpart, it had the serial number stamped on the barrel.

Model 1907 and 1905/1910 Match Target Rifle These very important single-shot rifles (two rifles are known to exist) are bearing special feature that would make the M1910 so different; the threaded locking lugs and receiver.

Military Match Target Rifle unlike the military Mk III this rifle was using a box type magazine with flat floorplate. It was using the Ross Mk III military sight modified to fit the .280 Ross ammunitions. Barrel was 26 inches long.

Developments

After the rejection of the Ross as a battlefield rifle, the Dominion Rifle Factory adapted the action to a light machinegun, the Huot, using surplus rifles. These were cheaper than the Lewis guns then in use. They were put to extensive trials; the war ended before they entered service.

Other users

Ross rifles were used once again in the Second World War. The Mark 3 Ross rifle was supplied to the Royal Canadian Navy, the Veteran's Guard of Canada, coastal defense units, training depots, the British Home Guard, Metropolitan Police, London Fire Brigade, Port of London Authority Police and the Soviets. Coast guard units in Ireland were armed with Ross rifles during 1920 to 1921.
