[QUOTE="daveosok, post: 74306"] If your wanting to shoot the 200 grain pills in smaller than magnum sized cases your going to need an extremely fast twist. I think I remember seeing somewhere where a barrel company offered a 1:7 twist. You must meet certain criteria when shooting high bc bullets, or any style bullet for that matter. You need to be able to stabilize it; you need to be able to push it fast enough to stabilize it. 200 grain pills are meant for extreme long range and will require fast twists and fast velocities to reach maximum potential. The 7mm rum, 7mm Tomahawk (I have the reamer for this) will do this but only in barrel lengths of over 30 inches. I'm sure some will say that you can get it fast in a short barrel but youll be burning faster powder and throat life will decrease faster. You want to stuff the case full of extremely slow burning powder and long barrels to get more barrel life. I currently have a 7mm stw 34 in barrel it has about 600 or so rounds through it and the throat is fine, no drop in accuracy but I am only using 74.5 grains of H1000 and 3100 fps. [/QUOTE]
