Well I tried some 1680 under Barnes 220gr flat points for velocity out of my 20" M-94 BB XTR yesterday. I loaded 36, 37 and 38.5 grns. Here is what I got. 36gr = 2123fps, 2113, and 2143. With 37gr I got 2123,2133 and 2143fps. That was a pretty consistant load I thought. 38.5 gr gave 2175,2185 and 2218fps the Av. was 2182 for that load. The number were just what I expected from the loading manual which used a 24" barrel. So if I can devlope an accurate load at 2200fps I think I will be happy. I had hoped for more, but out of a 20" barrel I just am not sure. Is anyone doing better?

That's an interesting suggestion. I am using 1680 because of Marshalls suggestions. 1680 produces very low pressures and high velocities in this round. I will call about the other powders. Thanks.

Just got my reply from Accurate Powders on the 1680 + 255 gr Barnes combo. They say that 35 or so grains of 1680 should give 2100 - 2150 fps from a 20" barrel!!! That sounds good to me. Now I just need to go load some up and put it over the chrono.
