Welcome to the forum ranch! My son has a 460 Encore( I hate to say it ) rifle with the 20 in. bl. and he shot a nice 5 pt. Pa. whitetail this yr. In my 460 XVR and his Encore I use the 200 gr. Barnes bullet over a 46.0 gr. charge of H110 with a Winchester LRM primer. I use Hornady brass for our hunting ammo. This will shoot 2 in. or less at 100 yds. in my 460. His deer ran about 30 ft. and piled up. He said it had a nice size exit hole in it.
