I just went to the range yesterday with my 7MM WSM
M70 Featherweight. This was my first round at the range working up some loads. Previously I had only shot some break in rounds with 160 grain Sierras and IMR-4350. These grouped just a bit over an inch. I live in Ca. so I have to hunt with non-lead bullets. Long story short, my two best loads yesterday were:
Fed 215 primers for both loads
140 grain Barnes TSX with 63 grains XMR3100, got a 1.1 inch 3 shot group
150 Nosler E-Tip with 62.5 grains R19, got another 1.1 inch 3 shot group
Rifle is pretty much bone stock, but I glass bedded, free floated and did a trigger job. I've got some more work to do but I felt this was a pretty good start and this rifle has some potential.
