I have a ss 7mm 1-9.5 twist that will finish at 25 inches. I bought two of them identical at the same time from Montana Rifle Company for my 7mm wsm i just got done building. My intentions were to chamber them both and shoot them and take the better but never got to cambering the second one. The first one has shot under .7 moa with no load work up yet. I want to say a three or four contour. It measures .650 at the muzzle. .870 before the radius to the shank. and has a shank of 1.2. Barrel is just under 26" now and so it would finish at 25". I would sell it for $175. If your interested in it let me know.
