I have several hundred 200g hard cast SWC's in .451 (for .45 ACP) from HSM custom. I have been reluctant to load and shoot these because of some serious leading in the barrel from previous attempts and just need a little help understanding how to best load for this lead.
Do I need to go for higher or lower velocities to keep the lead out? Instinct tells me to go low but I never found anything that seemed to work.
Powders I have on hand are...Bulls Eye, Unique and HP-38 and all are listed in my Lyman manual as useful candidates.
Lyman shows....
Bulls Eye at 4.9 min at 840 fps up to 6.0 max at 909 fps
Unique at 6.0 min at 717 fps up to 7.5 max at 913 fps
231/HP38 at 5.4 min at 769 fps up to 6.1 max at 885 fps
My last work up ended with 6.8g Unique and is where I stopped because I was getting some serious recoil and actually lost my front sight and never really found any accuracy.
Pistol is a 1911-A1
As always Thanks
