The one on the left is a Berry's, on the right a Ranier's, both are 230gr bullets.
I use either Bullseye or AA#2 for either bullet. 4.7gr of Bullseye and 5.3gr of AA#2. I seat to 1.250" or so. I shot them in a PPC competition of a few years and here is a picture of some of the targets. They were shot with a Taurus PT1911 that was stock out of the box.
