300blk question

OK so here is my issue from time to time. First off all brass is resized already, but every once in a while I'll get one that won't go all the way in the Sheridan case gage. I see the issue and it appears that the case head is not perfectly consistent. Now if I take 1200 sand paper to it lightly it goes. First off is this OK to do or should I chuck them? I measured the body and it's .374 and case head is. 377 after sanding. Sammi spec for .378 +/- .010, and case is. 375 +/-. 005. Thanks for the help folks.

Use a Small Base Die and it should be fine.
Remember the Sheridan Gauge is a SAAMI Minimum spec. and brass that doesn't fit in it will probably still fit in almost every gun out there.
I suggest trying to chamber a few empty cases that don't fit and see what it really looks like in your gun

These are from you Wes. You use a small base die correct? It seems where the case head is there is a burr and slightly out of round. Probably from the extractor.

Probably from an extractor if it is a burr on the rim of any sort.
I have never had 1 piece of our 300blk brass not fit in a gun out there, so if it is right from us, load and go :)
Even the small burr won't normally effect anything.
Body buldge at the bottom will still be smaller than SAAMI Spec and will fit in your gun
