I shot the 375 today and zeroed in at 100 yards. It did not kick as hard as my Rem 700 300 Ultra Mag. No muzzle brake or magna port needed, just a Simms Limbsaver recoil pad and all was good. I got some more questions about scopes and where you guys put your zero, but I'll start a new thread on that after I take a nap with my baby girl! I love having a day off work!!!
