I didnt have much luck with H380 either. H380 gets weird as the case starts getting full. My theory is that it packs up and doesnt ignite well. But you know what they say about theories.
3031 gave super results with 75gr bullets, and decent results with heavier bullets. I havent tried it on 117 or 120 bullets yet. Some things to keep in mind with 3031: - It meters poorly (not an issue if you weigh loads). - Pressure rises quickly as the load increases. Looking at my 3031 w/100gr data, the velocity curve arched upward, instead of being a straight line or leveling out as other powders do. I have noticed with my Mo 14 in 30 Rem that each grain makes a big difference when getting near 30 grains. Paco made a similar note regarding 30-30. - It is also a bit fast for optimum use in the 25 Rem with heavier bullets. Having said all that, I think it should do well with light loads in the Mo14 or 8. Its big advantage in that regard is that it is bulky. 26.25 grains of 3031 takes up the same amount of space as 29 grains of H380. So even light loads will do a decent job of filling the case.
In my preliminary tests, RL15 worked the best with heavy bullets in the Mo 30. RL15 is very close in speed to H380 but requires a less powder weight. Pressure behaves well as the load increases. With 120 gr bullets, I took it up to 32gr and near 2600fps in the Mo. 30. Best load for that rifle was 31gr for a little over 2500fps, but that is probably too hot for the Mo 14 or 8. I am thinking 27 to 28 grains should give you 2300fps, and mild pressure, depending on the rifle.
