[QUOTE="Boisedoc, post: 2501076, member: 99050"] Got the brass and dies today. I am building a kill everything that moves in NA rifle. The idea is a 20-22” barrel (suppressor), shorter is better. I am trying to get a reasonable (read not exploding brass) load that will get me minimum 2850fps. That should make for a max distance under no wind conditions of around 750yds. The 181 hammer hunter is the bullet I’d like to shoot. Am thinking a defiant antix XM action or a BAT Vampire. I emailed Hells Canyon about a barrel and am thinking a 1:9 or 1:9.5 twist. (1) What length barrel should I get? I don’t want so short that I can’t reach my velocity. Ideally would use a temp stable powder like H4350, 4831sc, or H1000. Got some Norma Brass. I think the medium length action will get me the COAL I need. (2) Is the SAAMI spec freebore long enough for that bullet (hammer 181)? (3) any other thoughts on actions or bullets? The gun will be used for thick woods whitetail. Timber and semi open country elk. Mulies. Black bear and hopefully one day moose. Probably never grizzlies. Maybe invading communists. Thanks [/QUOTE]
