Can You Shoot 7.62 x51 out of a.308 Rifle?
The.308 Winchester and 7.62x51mm NATO cartridges are often confused with each other due to their similar dimensions and ballistics. While they are similar, they are not identical, and the question of whether you can shoot 7.62x51mm out of a.308 rifle is a common one. In this article, we’ll delve into the details and provide a direct answer to this question.
What’s the Difference Between.308 and 7.62x51mm?
