Just for what its worth, I would not give up on these quite yet. I have over 50 down range and now with the new BC's my programs are matching up with my actual drops. My rifle shoots very well with the 300 smk's but I feel it is shooting tighter and more consistant with the Berger Hybrids.
Load work up was a breeze, ES is very low and here is the best part. I can consistantly hold 3 shot 1/2 moa groups as far as I have shot them. 300, 500, 700, 1000, 1188, 1340 and 1395 yards.
My rifle is a .338 Lapua, 27.5" Lilja 10 twist. I m pushing them just under 2800 fps.
So, if you have a Lapua or smaller cased 338. I wouldn't throw in the towel on them yet. You just might be cheating yourself out of something good.
