Long story short, I loaded up some .45 acp loads with 230 grain round nose plated HSM bullets for a Para-Ordnance 1911 .45 acp. More than half will not chamber easily and many leave the slide out of battery.
I ran them though a Dillon Precision case gauge and most of them do not pass the "plunk" test.
The overall length does not seem to be an issue.
Upon removing the stuck rounds from the case gauge, there seems to be a 'witness mark' right in the center of the brass just below the bullet base where the brass has a slight bulge.
These rounds were loaded on a Dillon progressive and I would expect them to be more uniform. If the crimp is good on one or many, they should all be pretty close, etc.
(1) Perhaps I didn't bell the mouth enough to seat the bullet center?
(1) Perhaps I didn't center the bullets good enough upon seating operation?
(2) Perhaps HSM bullets are more out of round than others or thicker plating?
-I did measure the remaining 40-50 bullets and they were all .451 diameter.
(3) Perhaps my crimp is improper?
Most of these rounds will not chamber through a magazine properly.
I don't have access to take a picture of them, but I could pull some strings to get one.
Help please!
