The Ross rifle is a straight-pull bolt action rifle chambered in .303 British that was produced in Canada from 1903 until 1918.

The Ross Mk.II (or "model 1905") rifle was highly successful in target shooting before World War I, but the close chamber tolerances, lack of primary extraction and length made the Mk.III (or "1910") Ross rifle unsuitable for the conditions of trench warfare, exacerbated by the often poor quality ammunition issued.

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 muzzle velocity and the cartridge acquired a very considerable international reputation among target shooters and hunters. Reports of such incidents like this were relatively minor.

Another deficiency was the tendency for the bayonet to become dislodged and fall off when firing the rifle. Lieutenant Chris Scriven of the 10th Battalion, CEF, commented that it sometimes took five men just to keep one rifle firing. Major T.V. Scudamore of the British Columbia Regiment, having been captured at Ypres after being wounded, wrote of the "contemptible" Ross rifle, "Those in the front line with that rifle will never forget... what it is like to be charged by the flower of the German army... and be unable to fire a shot in return".

Complaints rapidly reached the rifle's chief sponsor, the Canadian Minister of Militia and Defence Sam Hughes. He 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 negative reports regarding the rifle were published through the Ottawa Citizen, it became increasingly clear that his claims before the House of Commons that all the faults of the rifle had been cured were patently false and Hughes' defence of the rifle could no longer be supported by the Prime Minister. 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 7×57mm Mauser chambered Mauser Model 1895 rifle. In all, approximately 420,000 Ross service rifles were produced, 342,040 of which were purchased by the British.

Replacement

Canadians retained the Ross even as additional contingents arrived in France. On 12 June 1915, the 1st Canadian Division replaced all its Ross rifles with Enfields. 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 Pattern 1914 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 for training, in Canada and the UK, to release 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, for more M1903 Springfield rifles at the front. 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 the same time, the Dominion Rifle Factory (Quebec City) converted a number of Rosses into the Huot automatic rifle, under the guidance of designer Joseph Alphonse Huot. It was an effective design, feeding from a drum magazine, and cheaper than a Lewis Gun. Despite successful trials, it was never adopted for service.

Military variants

; Rifle, Ross Mk I

This was the first production military model Ross Rifle. The first few hundred were fitted with the full-length folding Sight, Ross Mk I. Before any were delivered, the sight was replaced with a shorter version graduated to 2,200 yards rather than 2,500 yards. Years later, this sight would be designated Sight, Ross Mk I*. Many weapons would have this replaced with the Sight, Ross Mk II, a curved sliding "Lange Vizier" type. The barrel was 28 inch long, and the fore-stock ended 4 inches short of the muzzle. The front band had a bayonet lug. The safety was a sliding flat plate on the back of the bolt handle operated by pushing a square button on the plate. 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 trigger 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. The weapon was a straight-pull cock-on-close design. 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 re-purposed as training rifles and fitted with longer front barrel bands as used on later production Rifle, Ross Mk II. This was done so they could more easily endure the stress of constant bayonet practice.

Military name changes

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.

Sporting variant

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

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.

Other users

British Coast guard units in Ireland were armed with Ross rifles during 1920 to 1921.

Ross rifles were issued 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 defence units, training depots, the British Home Guard, Metropolitan Police, London Fire Brigade, Port of London Authority Police and the Soviets.

Ross Rifles were collected hurriedly from stocks held in the Shetland Islands in May 1942 to re-equip the survivors of Operation Fritham in Spitsbergen who had lost everything when their ship was sunk. The Ross rifles and equipment being delivered by Catalina 210/P captained by Flying Officer Tim Healy.

In the 1950s straight-pull Rosses were well known in European sport shooting for biathlon and running deer disciplines. During the World Shooting Championships in Moscow, visiting shooters were allowed to sign for Ross rifles converted to 7.62x54R to try out the competitions. Before biathlon switched to .22LR rifles, it was fired with full-bore cartridge rifles. While various models of Swedish Carl-Gustav rifle were popular, Soviet biathletes had success with Ross rifles outfitted with slings, target sights and 3-position stocks.
