A few months ago I noticed my brass chambering tighter. I adjusted my cam over according to lee's
directions which kinda fixed or at least improved the chambering. I bought a Hornady case gauge recently
and noticed I have fixed most of the brass but a few I noticed have the case head slightly stick out of the gauge.
I watched a video on cam over and it's possible that I wasn't adjusting enough. Even with adjusting the cam over more aggressive but
not too tight, it didn't improve the seating in the gauge. However, these cases that fail the gauge
chamber like butter.  Is this anything that I should be concerned with as these cases only have been fired a
few times and never to max. Just not sure what I can do to get these cases to pass. I normally neck sized until I had this issue. This is with Hornady brass.

I wouldn't worry as long as they chamber. The gauge is most likely a minimum spec chamber. It just tells you if it works in it but not your chamber something is wrong. . Your cheer is most likely a little bigger.

That is what I figured but wasn't sure as on a different forum, someone with a similar issue,
the commenters said if the brass fails that brass is trash. It wouldn't chamber is there was an issue.
I should have had a gauge sooner but at least I know brass is fine.

I will keep that in mind to check how far back the shoulder being bumped.
I probably should anneal as well. I want to get the most life out of my brass.
