ULUL Stainless/Portless 6x45 16" AR15 Barrel Group Buy NOW CLOSED

Can you measure the necks on your fired rounds?

I chased a satern 6x45 chamber with a brand new reamer on my handi stub(which is going to shoot lights out based on early results), and I’m getting .269” on fired neck OD. I’m assuming we cleaned up the entire length of the neck as we had to cut the back of barrel off.

It confirms for me that the “barrel” from satern is good.

I’m curious to see what you have for chamber neck dimension. My reamer print shows .270” for chamber dimension of neck.

My neck diameter is about the same as Jesse's .258 for fresh, sized brass & between .2745 - .2750 in once fired brass (although, now I think about it, I didn't clean those necks before measuring)
Would soot make up 0.005"?

The ones I just measured that went through the handi were .269” not cleaned.
