I prefer to size and slice my .358 NM brass from .375 H&H. It doesn't get shorter than the already short .338 brass. My favorite load is 77 gr H414 over a 250 gr Hornady Spire Point. It has enough penetration to break both shoulders on elk with good weight retention. Sure, you can bump up to 275 or 280 gr bullets, but you give up the 30-06 speed and trajectory. I also load 200 gr. RCBS RNGC cast bullets over about 16 gr. of Unique for a great practice load.
