375 Winchester ammunition is a modernized variant of a very popular black powder round. The 375 Winchester was introduced in 1978 as an update to the classic and powerful 38 - 55 Winchester. The 375 Winchester utilizes a heavy 9.5 mm projectile, often weighing in excess of 200 grain.
While 375 Win resembles the classic 38 - 55 Winchester it is slightly shorter and much more powerful. Modern ammunition technology has made the big bore round much more potent, and the round operates at a much higher pressure. 375 Win ammo was designed for short to medium range hunting of medium to large game. Compared to most American hunting cartridges, this round is rather large with significant recoil. You can see our entire in-stock line-up of 375 Winchester ammo for sale below:
