[QUOTE="bigngreen, post: 262111, member: 13632"] My barrel is 1:11 twist and I'm concerned that it won't spin the 150gr bullets fast enough. I'm not sure that going to the 150gr is justifiable. Using LoadBase, I punched in my data but using Berger 140 and 150 gr for bullet data, assuming 3150fps for the 150's there is no advantage to the 150's till 700 yd and only a very, very little gain in energy. If I get on the lands I average 3390fps but it goes to a 1.5 group, I'm getting very little pressure signs but I need to get my ES tighter for long range. I've been thinking about trying some MagPro also. The only other rifle that I've liked this much is a Savage 250-3000AI, I'm really liking this 270wsm, :) you would't think it has the punch it does by shooting it. My goal is to have it all worked out by this fall so I can shoot 4-5 deer with it and get a good feel for what it will do and how the bullets perform. [/QUOTE]
