Frequently Asked Questions
Swiss K31 Ammo for Sale
What ammo does K31 use?
The K31 uses 7.5x55mm Swiss ammunition (also called GP11). Factory loads can be harder to find than common calibers but are available from specialty retailers. Reloaders typically use 168–175 grain bullets with powders like Vihtavuori N140 or N150.
Is 7.5 x55 ammo hard to find?
Not particularly. Our marketplace shows 4 variants across 12 retailers, typically around $27.55 per box. Major manufacturers like PPU and Sellier & Bellot produce 7.5x55 Swiss loads regularly. Availability is solid compared to truly obsolete calibers, though selection remains narrower than common rifle cartridges.
What caliber is equivalent to 7.5 x55?
7.5x55 Swiss is ballistically closest to .308 Winchester and 7.62x51 NATO. All three fire .308-inch diameter bullets in the 150–190 grain range at similar velocities. There is no direct equivalent, but .308 Winchester is the practical modern substitute with far wider rifle and ammunition availability.
What shoots 7.5 x55 Swiss?
The Swiss K31 straight-pull rifle fires 7.5x55mm Swiss ammunition, also known as GP11 (the Swiss military ammunition designation). The Model 1911 Schmidt-Rubin also chambers this cartridge. Note that earlier Schmidt-Rubin rifles used the older GP90 cartridge (7.5x53.5mm), which is not the same round.
