I have asked this question on my previous post, but I thought I would ask it again under its own title so hopefully it can get more replys to get accurate stats on actual rifles.
On the ADI powders web page it has 94.0 grs AR2225, 24" Barrel, 300gr bullet give a velocity of 2654 fps.
Using the theory of 50 fps more per inch of barrel, a 28" should be around 2854 fps, a 30" 2954 fps and a 32" 3054 fps? now I understand its a theory, and theres the point of negative effects of too longer barrel to consider, but it seems to me that some of the velocitys I read seem low?
Is 2750 fps out of a 30" barrel an exceptable level of performance from this chambering? I thought it would have been more.
I would appreciate some feed back from people who own a 338 Lapua or two
to share some of their rifles barrel lenghts and velocities, just to see what these things really do.
