In mechanical engineering, limits and fits are a set of rules regarding the dimensions and tolerances of mating machined parts if they are to achieve the desired ease of assembly, and security after assembly - sliding fit, interference fit, rotating fit, non-sliding fit, loose fit, etc.
Cartridges evolved from large-bore cartridges (.40 caliber/10 mm and larger) to smaller bores that fired lighter, higher-velocity bullets and incorporated new smokeless propellants. The Lebel Model 1886 rifle was the first rifle and cartridge to be designed for use with smokeless powder and used an 8 mm wadcutter -shaped bullet that was drawn ...
Engineering fits are generally used as part of geometric dimensioning and tolerancing when a part or assembly is designed. In engineering terms, the "fit" is the clearance between two mating parts, and the size of this clearance determines whether the parts can, at one end of the spectrum, move or rotate independently from each other or, at the other end, are temporarily or permanently joined.

The StG-940's design is based on the AK-74, [2] albeit modified. [2] This was done to evade restrictions placed on East German assault rifle production of their AK-74 variants imposed in order to prevent competition against the Soviets [2] based on their licensing agreement to not export any AK-74s made in East German soil abroad.

The SIG Sauer SSG 3000 (Scharfschützengewehr 3000, literally Sharpshooter Rifle 3000) [3] is a bolt-action, magazine fed rifle chambered in 7.62×51mm NATO.It was derived in Germany from the Sauer 200/Sauer 202 rifle family, that featured a modular construction allowing for easy replacement of components and changing between barrels with different chamberings.
This was in response to the need for overmatch when examining the capabilities of the 5.56×45mm and 7.62×51mm rounds compared to 7.62×54mmR. [10] The MG 338 was planned to have a similar weight to the M240 but, with the .338 Norma Mag, deliver terminal effects on targets similar to that of the .50 BMG .
