[QUOTE="Blackhawk41, post: 512660, member: 14357"] Liltank is right on the money your gonna need a 30+ inch barrel. But that being said you need to look at practicality to of the weight and length of the gun. I've always been taught that the 308 to achieve full/maximum powder burn in theory needs a 36 inch barrel. So I'd bet you'd need close to that if not a few more inches. I'm sure somewhere there is a formula or formulas to calculate powder burn and expansion of gas in the barrel. But thats bound to change with heat, and powder types. [/QUOTE]
