Overview

The Buffalo Bore Outdoorsman 220gr is what you carry when the threat has teeth, claws, and a body weight that exceeds yours. At 1,200 fps with a 220-grain hard cast flat nose bullet, this load generates 703 ft-lbs of muzzle energy and delivers the deepest straight-line penetration of any factory 10mm load.

The hard cast lead alloy is rated for high Brinell hardness, meaning the bullet does not deform on impact with heavy bone or thick hide. Combined with the wide flat nose meplat, the bullet cuts a clean, full-diameter wound channel without deflection. Buffalo Bore's published field data lists straight-line penetration exceeding three feet (36+ inches) in living tissue, which puts the round in the same terminal-effect class as light .44 Magnum loadings.

Carry the Outdoorsman in a Glock 20, Glock 40, S&W M&P 10mm, or Dan Wesson Razorback for elk camp, brown bear country, or feral hog defense. The recoil is sharp but manageable from a full-size frame. This is not a defensive load for two-legged threats: 36 inches of straight-line penetration creates significant overpenetration risk in any urban or home environment.
