Anyone ever ran into this problem. I recently purchased 3 new, factory sealed bags of 100 count each Winchester 357 cases. When I began prepping them for loading I found that about 10-12 per bag would not fit into my shell holder. A few of them would fit if I turned and spun them. I measured them with my vernier calipers and the ones that won't fit are anywhere from 0.003" and 0.006" bigger in diameter at the rim. Should I trash these or can I sand the rim to fit?

Need resizing ?
My first thought exactly...
I'd try using a fine file and lightly remove some excess. Compare rim thickness too on the bigger ones compared to the good pieces. I 'll bet that you don't need to throw any away.
It's the same shell holder that came with the die set. Bought it new about 8 years ago and have reloaded thousands of 38/357 magnums with no issue until this new brass.
I resized every piece before inserting the primers. But I am talking about the rim.
Edited to add: Lee carbide 4 die set. Shell holder came with the set when I ordered it new.

I dunt thunk that a resizer die is going to reduce the size of the case head???
it usually inside the shell holder!

Agreed...sorry, missed it was the RIM not the case mouth. Toss the anomaly cases...they could be nothing but trouble.
