[QUOTE="IdahoCTD, post: 636583, member: 13110"] Most likely you'll lose velocity more rapidly going below 26". At least that is the case with a 7STW. But for argument sake if you lost another 50fps that would put you at roughly 3080fps with 180's in a 24". A faster twist and 15grs more bullet will probably drop you below 3000fps but it's not something I'd sweat. Think of it just like your .300wm but with a way better BC and a slightly lighter bullet. A Hart 5.5 contour with a .750 muzzle at 26" will probably put you at .770-.780 muzzle diameter at 24.5". You could have them leave a little longer flat so it pushes the taper out further and it should get you to .800 at 24.5". They would probably do a custom contour with less taper too though. A Sendero contour a 24.5" would be closer to .850". [/QUOTE]
