Of the hard cast variety
Has anyone experienced a case bulge where the base of the bullet sits after seating?
I know a slight uniform bulge/ring happens on straight walled and tapered cases sometimes depending upon brass thickness and or bullet diameter.
A slim few of my 450BM cases have a hard to see bulge only on one side of the case. Like 8 out of 50 show it but you'd really have to look for it and they chamber fine even pass the "plunk" test.
I use Hornady 4 die set. And flare the case mouth just enough for the base of the bullet to sit square. When i set the dies up I left the lock rings loose and ran the cases up into the die to align them both and then tightened the ring.
The problem is that my son's friend came over to load some of his own 450s on my dies that are set up but 3/4 of his loaded rounds have a very noticeable bulge to one side and they do not chamber. My only guesses are that he may have thicker brass (new run of starline) and or he was not careful to align the bullet the best he could while seating.
I am going to pull the tips and run the cases back through the sizing die with the decapping rod removed. Then reload them.
What experiences have you guys had and any thoughts on what you think is going on?
