Some say that's pretty hot....the last batch of brass had 12 loadings on it. Primer pockets still tight, but the necks need annealed. I tried Ramshot Hunter also...it shot very well under some conditions, and sometimes I didn't know where it was going to land. H4350 is pretty much the standby for us...1/4moa and very stable. This is a very efficient accurate case...I think you will like it.
I use 41 grs. H4350 CCI 41 primers 130 Berger HVLD through a 22" Rock Creek barrel and get 2810 fps at 90 degrees or 20 degrees. This load was a accuracy load developed by Zak Smith who was one of the first to work with this cartridge and was the first load I tried after barrel break in and I have not tried another one since. Shoots 1/4". I love this cartridge, it is my Antelope round!!!
