Today, we look at something that’s near and dear to my heart – 7.62x54R, the centerfire cartridge that costs as little as .22LR. It’s fought wars against itself and won every time! It’s still in active production and military use, almost 125 years after its introduction in 1891! You can use it to shoot, gut, quarter, and cook the deer all at the same time!
