I've posted this before. I did some wet newspaper testing before I went on a Red Stag Hunt to Argentina. I was useing a 8x57 196gr. S&B SPCE and a 300 Win.Mag. Fed. High Energy 180gr. Nosler Part..
The Partitions penetrated further but all had spewed Their core.
The S&B's were not much farther behind The Partitions, and seemed to hold together pretty well. One had a mushroom about the size of a large Quarter - Very Impressive. Needles to Say, I ended up taking The 300. Just couldn't stand the thought of My cherished Mauser getting Lost.
