I made 50/50 alloy, Pure/COWW with 2% Tin. I came up with an alloy of 10 bhn according to my Cabintree. I cast about 2,400 of the large HP Boolits. They weighed 204 gr with the Lg round HP Pins with my alloy.
I sized at .452" and lubed with Carnauba Red.
I loaded up about 120 of the Boolits over 5.0 Gr of Bullseye using Winchester LP Primers, not a barn burner and headed to the range today. I figured I would be pushing about 850 fps. I was surprised. The Chrono said average of 885 fps. I wanted to see if I liked this load before I went into mass production.
I was still surprised this load would make 875-900 fps.
The good news, no feeding issues or leading out of my two full size 1911's, DE 1911G and Kimber Custom Crimson Carry II. I ran about 60 rds through both.
I was worried that the big honking HP might cause feeding problems. I racked several rounds to see if the feed ramp might damage the HP, but nope.
These boolits were cast less than a week ago and I like to age my alloy at least a couple weeks but running the softer alloy, it might not matter that much.
I don't remember the COAL. The boolits passed the plunk test well before I had them seated deep enough to not cause problems in the mags. I tested three different brand mags, the Factory Kimber and Desert Eagle and Wilson Combat.
You probably can't see it in the attached picture but there is just a hint of the front drive band sticking out of the case mouth.
I did not get around to see how well expansion or accuracy was since I was shooting a plate rack.
I figure expansion will be good with this alloy and fps. I'll test that another day.
Since I was still set up, I loaded the Boolits in the picture to have enough to load up three mags. I carry one of my 1911's and I like this round.
