I've used a lot of the old 1873 US Army bullet Lyman 454190 cast from wheel weights in the 1911. It's a semipoint and feeds slick as can be. Weighs 250-262 depending on alloy.

Very deep penetrator.

No more 1911's for me, but I cast a bunch of those Lymans not long ago for my Ruger BH w/ .454 chamber mouths and left a few over for my SIG P320.

Nothing like a 150 year old bullet for a "plastic" gun!
