Today on Alaskan Ballistics we’re shooting Underwood .357 Magnum verses 10mm Auto with their xtreme hunters series Alaskan BallisticsI’m just a regular guy who likes guns, hunting, and ballistics.

Today we’re shooting 10mm vs. .45 Super with Hardcast Ammunition from Underwood. The .45 Super is a 255gr Hardcast lead, and the 10mm is a 220gr Hardcast Lead. Which do you think will penetrate more? Alaskan BallisticsI’m just a regular guy who likes guns, hunting, and ballistics.

This is a follow up video. There were so many comments and I got a few emails on how bad the velocity was hurting the 45 Super. My buddy noticed the comments and decided to loan me his MK23 to test the theory.
