I LOVE Trail Boss in anything .45! I was using it a long time in 45 Colt before trying it in 45 ACP. I was having bad leading using HP-38 and cast bullets, and since I didn't have leading in the 45 Colt, I tried Trail Boss to see if that helped and it just about eliminated the leading.
Meters better than I expected. With an old Bonanza powder measure it's right on the money every time. With an RCBS measure it varies a little but still accurate.
Now I use it with both cast and jacketed, same load for both - 4.5 grains with a 230 grain pill. No leading with straight WW. With softer lead I get a little streaking near the chamber in one or two grooves.
