.223 case mouth size?

Hi
My 222 brass
Measurement internal Neck dia after sizing =.222 so about two tho NK tension
So think your right on the expander ball
👍

Thanks, I'd have expected about .002" neck tension. Thing is I've gone and ran ALL my brass through these dies so didn't have an old sized case to check and compare.

If it is consistent and you've not been getting any trouble leave it alone.

Do you neck crimp?

I can't leave it alone, if the necks are too tight and won't fit on the case trimmer they're not much good!

I don't crimp unless there's a cannelure, and that's pretty rare, so no I don't.

Cheers
Greg
