And I'll be the problem child with two 8 lb. jugs of H380 on the shelf. In my M788 .243 this slings 55 gr. at 4000 fps and 100 gr. Partitions at just over 3000 fps, but with sub-MOA accuracy. I've tried the rest, H380 is the best metering with good velocity and accuracy for me. All the others mentioned will work well, but I've NEVER used a powder that meters better than H380.

I've never come across another powder that was as much like little marbles as H380. I have had some very good luck with it as well. (My best luck was with 150 grain Speers in the 06.) It also the powder that I have seen the greatest range among different load data as well as the most dramatic change in load data from a single source over time. Best, John
