I bet that’s a stout load. I’m pushing 180gr. Jhp at 1300 with 9 grains. With 5” bbl.

Thank you. ✅

I bought some 200 grain cast from Montana BW. Hadn?t really found hard load book data for them. But thinking ill probably end up in the 8gr. or so range. But starting at 7.5gr for what I have loaded now. What y?all think? I?d like to get around 1150 fps.

I bought 3 pounds of it thinking it was a viable powder for the 10. Started at 11.6-13.0 grains and never got past 1065fps on the chrono. I say it?s to slow and hard to ignite. I used cci 300 and fed LPMM.  Blown unburnt powder in my slide and barrel with both. I?m going to pull unshot loads back down and try 3n37.
