[QUOTE="mt_archer, post: 703395, member: 26573"] 26" will be adequate, but if this is a heavy build for long range, a couple extra inches will help. 10 is great all around twist, but the 9 & 9.3 twist might be better to run 300 grain bullets and the new longer bullets. My last build with 1:10 (kreiger #17, 28") in lapua ai just doesn't like 300 gr, but is awesome with 250's, so next one will be 1:9. Unless you go carbon wrap, you probably want at least #7, and heavier is better, especially for longer length. You can save some weight with fluting, but not much. I'd suggest you figure out goal weight and work backward. Also plan ahead on what bullet you want to shoot. That may influence your choice of stock and bottom metal, too. [/QUOTE]
