OK,
So I was a bit sarcastic, with the 21 loads.
I have 3 different loads, PERIOD.
I load the LYMAN #452374, seated to the start of the OGIVE & taper crimped. FULL POWER LOAD. Works in all my .45 ACP handguns.
LYMAN #452488, seated to the edge of the bearing surface. Loaded light for Target use, it functions in all 1911 Handguns. All of which are ramped/throated. Just change the spring weight. Works well in the Blackhawk, GREAT accuracy.
RCBS #452-201-SWC/KT, seated to edge of bearing surface & taper crimped. Loaded to a Full charge this is a Combat type load that functions in all guns. It's the load I take to the range for punching clean holes in paper, with the "furrin" guns and RUGER Auto.
