Do sized, unflared cases drop fully into the gage and freely fall out?

Yes they do I have also tried to re-align the dies by running it up with cases in it and loosening the top screws and then tightening them.I have also decreased the flare a bit.This is all helping but still getting some of them bulging.

What does the outside diameter of the case mouth measure on a loaded cartridge? It should be .469"-.471". The Overall length on a loaded round with a 230 grain RN should be 1.250"-1.260".

RE: .45 acp cases bulging

I'm having the same problem on my Square Deal B with 185 grn lead wad cutter. Any suggestions for a fix? I make adjustments to the crimp and most come out ok, then now and then a bulge occurs. I gauged after each step and the shell falls from the gauge until the crimp so I have been up and down on the crimp with the same result.

Where does the bulge occur on the case? Be aware that the size die intentionally undersizes the case, so you will see a reduction in the case diameter just below the base of the seated bullet.

RE: .45 acp cases bulging

When I originally tested the case, I ran it through all the stations without a bullet inserted in the case and it gauged fine. I checked a round after seating a bullet in the case gage and found that a bulge was formed near the bottom. So I turned the crimp die all the way down until it stopped and ran the round through. Now the finished round goes in and out of the case gage freely. I ran all the previous rounds through the crimp stage, now they all gauge freely.
