This for all....I started in ernest working up a decent hunting load for my steyr 7x57 two years ago. I tried various combinations of bullets and powder including both imr and hodgdon 4320, 4350, 4895 and 4831 with fair success. My neighbor who lives up the road a ways stopped by one morning while I was shooting and I found out he had been reloading the 7x57 for over 30 years. Armed with a new brain trust, I took his advice and picked up some imr4064. The results were awesome. Not only did the groups tighten up, but the velocity shot up 100fps with less than max loads. I'm reloading the nosler/win combined technology 140 gr BT and averaging 2920 fps. See pic attached. Sure made my 7mag obsolete as 20 more grs of powder and the kick just ain't worth the 200 fps on WTD. Go figure. If you want the receipe, e-mail me and I'll send it with a pic. can't load pics on this browser. Regards, Rick.
