Ok, I now have some results of my loads.
*NOTE* Speeds are based on factory ammo posted velocity on cheap federal box of 3110fps with 150gr hot cores hitting at the same height as hand loaded ammo on average @ 100yds.
58gr loads did pretty good with .960" 5 shot group at about 3000fps
59grn of h4350 yielded a 3 shot group of .4660" at again about 3000fps
60gr opened up enough that i did not even want to measure it...lol
so that having been said i believe the winner is the 59gr load of H4350 with the 154gr Hornady SST's should make a decent Elk round within reasonable distances, don't y'all think?
