Underwood Ammo‘s Gas Check load in .460 S&W Magnum (brand part no. 726) drives a 360-grain hard cast long wide nose bullet for hunters and backcountry carriers who need maximum penetration on the heaviest, most dangerous game. The hard cast lead bullet rides a copper gas check at its base, a small cup that seals propellant gas behind the bullet and keeps the bore from leading even at .460’s high velocity. The long, wide, flat nose is a deliberately non-expanding profile, built to punch a straight, deep wound channel through heavy muscle and bone rather than open up and slow down. For .460 S&W Magnum shooters who need penetration above all else, this handgun ammunition is built for that job.
