[QUOTE="J E Custom, post: 744149, member: 2736"] I have built many 280 AIs that weighed less than 8 to 10 pounds(Depending on the stock and scope used) using a # 5 or #6 Lilja. This contour is heavy enough to be accurate with the .284 bore. I will normally recomend a 24'' to 26" barrel and these barrels will weigh around 4 pounds. The 280 AI is very accurate and capable beyond 1000 yards. I recomend using a standard 280 head space gauge with the AI reamer so you can fire form standard 280 ammo while hunting with factory brass or ammo. They are very accurate if set up this way(There is a .004 difference in head space in the new SAMME spec 280 AI and the standard 280 Rem). A 1 in 9 twist is perfict for bullets between 120 and 168 grains,and 3 or 6 lands is my choice. With this combanation , no muzzle break is needed and 140 to 160 grain bullets can be pushed as fast as a 7 Rem Mag in the 280 AI version. J E CUSTOM [/QUOTE]
