Been running these same thoughts through my head. Have a rem ultra mag action, also a crux ti long action in the safe, 28" 9.3 twist proof barrel. The big heavies require more capacity than the 33 nosler in my opinion. So it was 338 rum, or edge. The edge needs a 4" mag to run properly, the 338 rum can utilize the 3.8" box. The rum will push 270-285 Hornady eld bullets over 2900 fps with RL26. Ordered 150 pcs ADG 338 RUM brass today, had the vendor sample 20 random cases, weighing 265.7-267.1 that's most at 266.x gr, very good looking and TOUGH brass from my reading. I'll utilize the rem 700 steel action on this build as I don't need a 7# rum. With the rem action, 28" carbon sendero, and AG Composites thumbhole stock, I'll be around 8.25# prior to optics. I'm excited about this hammer! It doesnt offer much on my 300 norma, but the 338 has a great reputation for killing big bodied animals at range. Ask
@Broz about it.....
