47.5grs of 3031 and a 220 Speer runs 2440fps from my 22" barreled Hawkeye and is right at 1".
I shoot the 200gr Hornady with 47grs H4895 at 2500fps mainly.
That's a good load about .5 grains under max right for the 220?
That 200 gr Hornady load sounds darn close to Hornadys factory 358 load. I think they print 2475 on the box!
While not a .358 my .35 Whelen likes 225gr. Nosler or Sierra bullets over a moderate charge of IMR 4064. This load should do well in the .358 too.
My concern with the bigger bullets and 4064 is I will run right out of room in the case and have a fairly compressed load? Maybe not. I like 4064 I'll have to explore it thanks!
