If you are getting soot on case and getting powder in face with mouse fart loads, your charges are too low to properly seal case mouth/neck with chamber and high pressure gas is pushing unburnt powder granules back.lower power loads in 1911 45 and noticed ... little spray of dust, grit (powder)? Back towards my face.
cases are a sooty mess ... HP38 ... mousefart loads ... Gun issue or a reloading issue?
My favorite 45ACP mouse fart load is 200 gr LSWC with 4.0 gr of Promo (Referencing Red Dot load data per Alliant). Very accurate 2" groups at 25 yards and no unburnt powder to face.1911 45 ... mousefart loads
Thanks Murfswitch to bullseye if you can. I have run 38 special down in the 400 fps range with no problems with this powder (caution: don't try this at home as you probably will stick a bullet in the barrel).
Yep, At 2 cases per 100 it doesn't sound like much of a problem.I guess this is the price you pay for mousefart loads.
