Great bullets

By Jason B. on Oct 17, 2025

I use deep curls in alot of my handguns. These I bought for the 454 casull, and 450 bushmaster. I'm sure they will do great on both. A+++ graf's.

Tough bonded bullets

By Scott C. on May 06, 2021

I bought these for shooting out of a bolt action chambered in a 450 Bushmaster and couldn't be happier with the accuracy and penetration. If you want a super tough bullet for 1900+ velocities this is the one that I recommend especially if you might shoot an elk or moose in the shoulder.
Very tough bullet!!
