Hi All,
I've just reloaded my first ever batch of ammo, and I've run into a problem that I hope someone here recognizes.
I'm using once-fired Federal brass in .270 Win. After trimming to length and neck sizing the brass, I checked the whole batch, and all of them chambered normally. After charging and seating the bullets (Hornady 130 gr SP) every one chambered very hard. I checked OAL, and that was not the issue. I found that every round had a very slight protruding lip formed right at the mouth. After gingerly removing this slight lip, the rounds chamber normally.
I have to guess that the lip is formed by seating the bullet. I didn't chamfer the mouth, only slightly relieved the edge left by trimming.
What am I doing wrong? Should I be slightly chamfering the mouth rather than just deburring it?
