Guys, thanks again for the input.

BigBulls, I understand what you are saying about published velocities and the shorter 22" barrell, but isn't it relative? For example the 270 WSM and the 30-06 in the BLR both come in a 22" barrell and the balistics charts are based on the 24" barrell, so wouldn't I see tsimilar deterioration in velocity in both. In other words aren't I still comparing apples to apples?

You did make me think though, about the .308. The balistics I'm comparing are for 24" barrell and the BLR barrell is only 20". It looks like I need to do the math and factor down the velocity and energy based on barrell lenth for each round (keeping bullet wt as consisitant as possible) and compare. I might see if I can do the recoil energy calculation as well, but that one seems a little complex.

Thanks, this has got me thinking.
