[QUOTE="J E Custom, post: 1932250, member: 2736"] I wouldn't go any smaller than a #3 or #4 contour on the cartridges you mentioned, And 22 to 24'' inch barrels, you don't save that much weight by cutting the barrel 18 to 20'' but you will lower the velocity greatly if you are 20'' or less with most of the cartridges you mentioned. Also with some of the cartridges mentioned you will probably wan't/need a muzzle brake for a short light weight rifle and threading the barrel on the light contours can be risky based on barrel wall thickness. I prefer to use a # 4 or #5 for my light weight rifles and it is easy to keep the weight under 6.5 to 7 pounds if you watch the weight of the receiver, scope bases and rings and the scope it's self. my 338 RCM is under 7 pounds fully dressed, but the muzzle brake was necessary to control muzzle rise and recoil. Just my opinion J E CUSTOM [/QUOTE]
