In 2005 they won the contract to supply the Canadian Forces Land Command with the C14 Timberwolf MRSWS for $ 4 . 5 million . The military version of the rifle , which is being used to replace the C3A1 sniper rifle , started as a civilian precision sport rifle . The military rifle however has several modifications to make it better suited for military use and many accessories are available . The official military designation for the rifle is C14 Timberwolf Medium Range Sniper Weapon System ( MRSWS ) . History . The Timberwolf rifle was originally developed as a civilian long range hunting and sport shooting rifle for super magnum cartridges by the Canadian company Prairie Gun Works , now PGW Defence Technologies Inc . The civilian Timberwolf rifle is offered in several chamberings , up to the . 408 Cheyenne Tactical cartridge and the . 416 PGW cartridge , a wildcat cartridge based on the . 408 Cheyenne Tactical . These rifle cartridges are dimensionally larger and are more powerful when compared to the . 338 Lapua Magnum cartridge used in the C14 Timberwolf used by the Canadian military . During the 1990s the Canadian Armed Forces formulated a requirement for a sniper rifle that could fulfill an anti - personnel role up to 1 , 200 m ( 1 , 312 yd ) . This long - range anti - personnel rifle would replace the aging C3A1 bolt - action rifle which fired the smaller 7 . 62x51mm NATO cartridge which had been in service since 1970 . In 2001 during trials for new sniper rifles at CFB Gagetown , the C14 Timberwolf MRSWS was picked to become the new designated anti - personnel sniper rifle for the Canadian Forces . The C14 Timberwolf MRSWS went into production for the Canadian Forces Land Command in 2005 . Since the introduction of the C14 Timberwolf MRSWS , the C3A1 rifle has been slowly removed from active service . The C14 Timberwolf MRSWS is now the main sniper rifle in the Canadian Armed Forces arsenal . It is highly rated by snipers , who like the rifle itself as well as the additional effective range and penetration the . 338 Lapua Magnum offers over the C3A1 ' s 7 . 62x51mm NATO cartridge . The C14 Timberwolf ' s accuracy potential is stated by its manufacturer as sub 0 . 75 MOA with proper ammunition . The Canadian Forces accuracy standard was evaluated by hit probability with a requirement of hitting a chest sized target at 1 , 200 m ( 1 , 312 yd ) 90 % of the time . PGW Defence Technologies Inc . averaged over 95 % on this standard and every weapon delivered under the Canadian Armed Forces contract was evaluated for accuracy and witnessed by DND officials . Design details . The C14 Timberwolf MRSWS rifle is chambered for the . 338 Lapua Magnum rifle cartridge . The rifle achieves a maximum muzzle velocity of 838 m / s ( 2750 ft / s ) with 19 . 44 g ( 300 gr ) Sierra Matchking very - low - drag bullet loads . Such loads are much more powerful compared to the 7 . 62x51mm NATO cartridge used in the C3A1 rifle which typically fires 11 . 3 gram ( 175 gr ) bullets at 790 m / s ( 2580 ft / s ) . Operating mechanism . The Timberwolf action is a manually operated stainless steel bolt action with a right - hand side bolt and ejection port . The bolt is a rotary bolt with dual front locking lugs plus one locking lug at the rear . It requires a 90 - degree bolt rotation . the bolt is partly helically fluted which reduces weight whilst maintaining strength . A double plunger ejector and hook type extractor are used to remove fired cartridge cases . This helps create a very smooth action which is very reliable . The extra locking lug at the rear assists in preventing the bolt from becoming jammed when chambering another round . Though not in Canadian military use the manufacturer offers a titanium receiver as an alternative for the stainless steel used in the C14 receiver . The use of titanium reduces the weight of the Timberwolf bolt - action . The single stage trigger is adjustable for weight , creep , and over - travel . Barrel .

The barrels are cryogenic stress relieved and partly helically fluted which reduces weight whilst maintaining most of the structural strength and contains a detachable proprietary stainless steel muzzle brake which reduces the recoil .
