[QUOTE="Ernie, post: 2357412, member: 13"] I have a 14.5" 308 Winchester XP-100, shooting the 168 A-Max at 2445 fps. At 450 yards my impact velocity is 1779 fps. Back in the day I had a 14" 7-08 and I ran 140 NBT's at 2530 I think & 120 NBT's at 2700 fps. the 140's killed fine at 400 yards and a tad further. The 243 Win with a slow twist, I don't have info for you, but I can give you data for a 15" 6mmBR with factory100 grain CoreLokts. MV of 2520 fps and a impact velocity of 1756 at 400 yards. You would be better off staying with a 14" barrel versus a 12.5" barrel in my opinion. With the exception of that 6mm BR (A Factory Custom Shop XP-100), all of my 6mm's are 7-8 Twist barrels, and I shoot the 103-108's. [/QUOTE]
