I'm looking for some loads for 7mmWSM. I have 100 and 140 grain bullets. I have some WMR, some IMR 4320, and Varget. I can get about any powder locally, just need some ideas.
My model 70 featherweight will put 5 into under an inch with the 140gn Nosler BT or accubond and 66.5gns of H4381 . Velocity is around 3150 FPS .Others have had success with this load too . Warmer loads less accurate . 66.7 gns of WXR (same as RL 22) gives similar results . Seat bullets off the lands .My rifle likes the Winchester LR Magnum primer.
The hunting imperative was part of every man's soul; some denied or suppressed it, others diverted it into less blatantly violent avenues of expression, wielding clubs on the golf course or racquets on the court, substituting a little white ball for the prey of flesh and blood. Wilbur Smith

I have tryed many powders, but the best groups my brother shot what he called a ace .100 with 67gr H4831 & 140gr Nosler BT only 3 shots I tryed same load at 200yards .460 This gun is Rem700 24" Hart barrel, mcmillan stock, beded, jewell,& tubbs system. its a light hunting model 6.7lbs very pleased with this gun.
I have been trying H4831sc for 140 and 160 Accubonds with no luck. I just switched to RL22, and my groups are near 1.25 inches with the 160, haven't tried it with the 140. This isn't where I want to be, but is still about a 2 inch shrink! This is a starting load, so I am going to add powder and change bullet seating to improve it.
