I'm....not sure you read what I posted.

I have been using a full length sizer die for years. I've fired hundreds of rounds through the full length sizer in this rifle. I just recently purchased the neck sizing die to try something new.

- I was surprised to find freshly fired brass, run through the neck sizer, failing the NO-GO gage.

- I was subsequently surprised to find the freshly fired brass coming out of my rifle without any processing failing the NO-GO gage.

- The oversized brass chambers just fine (no bullet, no prime. just the neck sizer)

My question is - what is this telling me? Do I have a headspace problem with my rifle? As I understand the Wilson gage, it's cut to SAAMI spec. Every round I've sized with the full length sizer in the past has always passed the NO-GO.
