[QUOTE="lerch, post: 107650, member: 3115"] [b]Re: 300 R.U.M., with a 30\" Barrel?[/b] BJ has had great luck with the 240gr SMK in his rum with a 1-10 twist. Shoots .5 or better everytime. Only problem with it is that once you get to 1600yds the bullet has heart attack. I believe that BJ is only marginally stabilizing this bullet and once it hits the subsonic transition it destabilizes. It is a amazing thing to see, the gun will shot moa to 1/2 moa out to 1500yds and then within 100yds it will group in a 10ft circle. It think a 1-9 twist would be ideal. BJ's bbl is also a tighter bore than normal. I dont fully understand this so maybe he can ellaborate more. I also hear that Hornady is coming out with something pretty sweet here soon. Will have to get back with you all on it when I get some more info take it easy steve [/QUOTE]
