I've shot the 300 gr Berger's and the 300 gr Sierra's in my Remington 700 338 Lapua. I can't say I have the load tuned in exactly where I want it yet, but I think the Berger's are more accurate in my rifle. Then again, I've always found Berger's to be the most accurate bullet available as long as you have a fast enough twist and seat them into the lands. I can't used the magazine with the Berger's seated 0.010" into the lands, but that's fine with me. I perfer accuracy over capacity. I've been using 90.0-92.0 grains of H1000 powder, Remington 9 1/2 M magnum primers and Hornady brass(2700 fps). I swapped out the stock muzzle brake for a JP Recoil Eliminator and the difference was night and day. It's recoil is now like that of a medium to heavy weight .243 Win. The recoil is less than my 20+ lb .284 WIN HBR rifle. It wasn't a lot of fun to shoot before I swapped out the muzzle brake. Best $100 bucks I've spent in a long time. Good luck and please feel free to share any good loads you work up.
