yep .458 is easy to find! Local gs has all i need for a pistol build but im thinking cheep as always but at a 1$ a shot is justified by the .308 cost? Im not doing a pistol cuz i own a couple .45's i do have a 16" and 8" .300 blk im good there ? im wanting an exotic cal to say i have one but again im on the cheep side of exotic. makes it more fun for everyone but can still rattle the teeth! Thanks brothers the hunt is on! I have to bone up on terms and procedures for reeming a chamber. Still looking for a bolt size? Been to busy or not looking in the right places? Ps : am i giving jon 35$ or are you all funding my first box of ammo? ( ed mojo) ?
