So I'm working through a 500 count box of SNS Casting coated .44 Mag 240gr SWC .430" dia bullets, and I'm noticing something a little off.
The crimp groove seems pretty shallow, so when I crimp the brass, it's not coming out quite right. Either I don't see it crimp quite enough and the neck to bullet fit looks gappy, or I set the die for a harder crimp and the die shears a tiny sliver of brass from the mouth. The mouth of the brass is stopping just below the shoulder(?), exactly where it should. So I don't think the seating depth is the problem. This has happened with Fiocchi and Starline brass, on 200 rounds.
I have not had the same issue with the SNS .357 Mag 158gr coated SWC I've also been loading. The groove on those seems more pronounced and they're crimping very nicely.
The shearing doesn't seem like such a big deal, except it could be reducing the life of the brass. So I'm wondering if this is just a rough batch, or if others have had this issue.
