cases are not going in all the way, must be the crimping I just order a Lee taper die, will see when it gets here, thanks

Are you taper crimping them? If not, that might be the answer.

I lower the seating depth and just got a LEE taper crimp die, re did 50 rounds and it seems to work, have to try with live fire and check for excessive pressure, my loads are pretty mild anyway @ 5.4 of unique, I want thank all for the interest and advices.

My gut feeling is that you have a bunch of well used .45 brass. The Lee die will probably salvage it. I'd buy a box of factory ball, shoot some and try loading the once fired brass with your current settings. If that works, your brass is most likely the culprit. I load for a bunch of different guns and have some 50 plus year old brass (RA63) that's still going strong. The only thing my HK 45s won't run is the Hornady steel case traing ammo.

1977 was a fine year...

As you say, stuff like this still runs fine for me.
