My favorites are "barn burners", i.e. LBT style, Gas Checked 335gr. over 22.0 gr. of WW-296, CCI-350 primer, very firm crimp.
These loads are for "full sized" Blackhawks and not the "mid frame" guns unless they are a custom made 5 shot version.
Hold on tight when you "trip the trigger" :shock:
flatgate
PS very similar components but a small rifle primer and way more powder runs at 1375 fps out of my F-A .454 :D
