A minor problem is that it cannot fire as fast as the 458 Win Mag. My dearest general rifle is my Ruger PC4 in 458 Win Mag.
I like the the 6 mm BR best for trophy buck hunting. Our best-loved rifle is the 458 Win Mag I picked up online at the NRA store. My most popular caliber is probably the 458 Win Mag from Wal Mart in Mud Bay. My Mom got her 458 Win Mag online at Dick’s Sporting Goods.
