[QUOTE="sdiehn, post: 36658, member: 3005"] What i was orginaly trying to get at was that a lot of times when you find a load out of a good gun that shoots great out to 300 -400 yards you will usely find that the bullet is marginal for the twist.Now if its a gun that has some throat erosion this will compond the problem one of the guys i use to work with had a 240 NM with a 10 twist (this gun shot sub .250 5 shot groups) and shot the international 3 postion he went and practiced at 300 yards before going to Fort Benning the difrence was 300 yards to 300 meters that difrence with the fact the throat was on the way out was masive. He set the barrel back .060 not much for a bad throat and the gun begain to shot again this rifle even when he first built it would not shoot 600. There are a lot of pricopals and formulas that peaple use as a absulute hard and fast rules. this has to be because the math or computer says so. But in all acuality the practical use and experiances are tottaly difrent. My guess is that stray is useing a lite bullet in a faster twist barrel say 130`s in 30 cal. and a 10 twist or heavy bullets in a slow twist say 80 grainers in 223 cal. out of a 10 or slower twist. When I try to diganose a problem their is a process that I go threw steps to find out what may be the problem one of the most commom problems you find is that shooters are useing the wrong bullets for what the barrel is set up for varmint bullets out of heavy game barrels or heavy game bullets out of varmint barrels [/QUOTE]
