Didn't know that that 6.5 swede was used much for long range stuff. In my experience, RL-22 is pretty much the perfect powder for for the cartridge though.

I did some load testing with my M41B this weekend and was getting 3 shot 1.25" groups at 200 yards using 140 gr SMKs and rl-22. I need to do a little more fine tuning, but I think I can do better han 1/2 Moa with this combination. Even more interesting is that the tightest groups were around 44.ogr and 46gr charge of powder, which is similar to what other M41B shooters have found.
