Hi JRKRK,
I have a .375 H&H on my Encore. Originally had the plastic stock and forend, but the forend mounts would break from recoil, so I went to wood. Still had a pretty good kick on the bench with my .270 SP Hornady bullets, 77.2 grns of IMR-4350, so I sent it to KDF in Seguin, TX for a muzzle brake and Pachmayer Decelerator pad. Shoots like a .30-06 now and I like it a lot better. If you go with a muzzle brake, just be sure to wear hearing protection. Shot a Remington 700, .375 H&H with a KDF about 4 years ago. It's definitely a sound you won't soon forget. My ears rang for 2-days after just one shot. Good luck!
Karl
