[QUOTE="J E Custom, post: 34507, member: 2736"] JD Im a little slow on your reply but maybe this will help Bench rest shooters seem to like hand cut rifle barrels with 3 or 5 groove. The way it was explained to me what the barrel did to the bullet affected it greatly once it leaves the crown because of balance at extreme RPMs . In other words Bench shooters like no freebore{most accurate way to engrave a bullet] hand cut rifleing in 3,5 and 7 groove {odd number grooves,splines,blades,spokes,etc all tend to be more balanced at higher rpms} and a single point cut crown. I am a hunter and some of these things are not practical "ie" No freebore, but the best barrel is a great place to start. [/QUOTE]
