[QUOTE="Fiftydriver, post: 106097, member: 10"] I know a 1-12 will stabilize a 200 gr Accubond in a 300 RUM rifle. With the lower velocity of the 300 Win Mag, I would feel that a 1-11 would work very well and even a 1-10 would not be to fast. Would also allow you to shoot heavier pills if you wanted. I personally feel a #2 contour is to light in any 30 cal rifle unless it will be used strictly for a general purpose big game rifle for hunting under 400 yards. Now before some get all hot and bothered. I know full well the lighter barrels can shoot very well. Problem is they are much harder to shoot with fine accuracy. They are light which can cause them to be very lively when trying to settle down for a shot. Recoil also increases dramatically without a brake. Personally, I like a #4 contour as a minimum recommendation for a 30 cal magnum. If you want it lighter then get it fluted but I like to see at least this much steel around the bore. It also depends on how long of a barrel you want. With a 300 Win Mag, 26" would be perfect for a walking rifle and even 24 to 25 would work even better for barrel stiffness and portability. Anything over 26" I would strongly recommend more barrel mass and bump up to a #5 contour, fluted if wanted. Any of the top barrel makers will get you a fine barrel. Go with a Lilja, Krieger, Rock, Broughton, Hart or any of the other top end makers. Then find someone that specialized in building accurate big game rifles. The machining is at least as critical as the actual barrel quality. My recommendation would be very simple and not so sexy, a #4, 1-10 twist just to cover all the possible bases. I have yet to see a 1-10 30 cal barrel not shoot bullets from 125 to 210 gr extremely well when fitted properly. Good Shooting!! Kirby Allen(50) [/QUOTE]
