I have a couple of Encore barrels with a lot more recoil than a 7mm Rem. Mag. with T/C's Muzzle Tamer on them and I'm quite satisfied with them. Actually, I have a 7mm Rem. Mag. barrel with a Muzzle Tamer on it and the recoil is quite gentle. In my opinion, T/C's Muzzle Tamer is the most economical way to go and won't void T/C's lifetime warranty. The barrel can be shortened a bit when the Muzzle Tamer is installed but, if you shorten it too much, the flutes are going to look funny.
