If you already have the brass why not sell off some 454 brass and buy .45 Colt brass? It would be a lot less trouble and work.
I've sold quite a few bags. Still have a lot.
I also worry about my missmarked brass getting into the wrong guns after I am gone. Some will say after your gone it won't matter but I still don't like the idea. I'm old school!!!!
Since its marked 454 Casull it wouldn't matter if a trimmed case was fired in a 454 since 45 Colt can be shot in it. Along those lines, I have wondered about someone trying to fire my 375JDJ rounds in my 444 Marlin lever action after I'm gone. Its head stamped 444 Marlin so someone unfamiliar with the round could make that mistake. Before I bought my 375JDJ barrels I still had some 338JDJ#2 rounds left after I sold that barrel. Didn't like the idea of those being fired in the 375JDJ by mistake so I got rid of them.
