Thanks for your pounding the brass warning! I've been to this dance before.

My 45 ACP Load is similar, using a plated bullet and getting advertised velocities.

Federal vs Winchester brass while significant to someone, probably varies less than shot to shot variation.

Groups are great, primers are less deformed than factory loads, SD is good, this load is not over pressure....Actually, I would guess it about 28000-30000 psi, from what I see.

Now on to something important. My COL is 0.010 longer-pressure down, but ~ 2000 psi?? 10" barrel was shown in your data, but the 2013 Annual shows 4" tube. Hmmm, I'll bet you are right. I'll bet they had a misprint of some sort. Ballistics by the inch shows 340 fps difference fro 10 to 4.
