Although this cartrigde is different (7mm-300 Weatherby) the accuracy loads posted here for the 7mm STW work well in my rifle. I have found in my 7mm-300 that H-1000 gave me the best accuracy but I have a 30" barrel.

80 gr Rl 22, 140 gr Barnes x, col of 3.695. 3300 fps, sub moa. I can use 81 gr with the Noslers, more accurate, and a little faster. Out of a Rem 700 with 24" barrel. I built mine way back when it was a wildcat. Next time it will have a much longer barrel (and will probably be a 7mm RUM to boot). Good luck. - Dan

Try some RL25 starting at 80 grains and work up with a chronograph. I shot 140 gr partitions out of my 27" stw at 3500 fps with 82 grs of RL25, 84 grs gave me 3600 fps. You should be able to get 3600 fps easily out of a 27" barrel with moly coated ballistic tips.

I load 82 gr of re25 behind a 150gr nos bt. It's average chrono is 3425 in my 27" barreled STW. I tried H1000, wc860,872, 7828 and settled on re25. Hope this helps. fws
