Wilson Inside Neck Reamer for Donut Removal

[No i deer]

Wilson specifically states that their standard neck reamers are .002-.003 larger than bullet diameter. Whether it's a tight neck or standard neck chamber doesn't really matter...you need to order the correct reamer dimension for what you intend it to do.

P.S. Blending into the shoulder when turning the necks helps reduce the formation of donuts. I normally push the shoulders back .020-.025 and simply cut down to the 'pushed back' shoulder. When the shoulder blows forward during f-forming, you have your 'blend' cut.

In my nativity I wasn't aware there was a standard size and I needed a custom ground reamer to suit a tight neck and I thought I was supplied with the correct tool for the job..!!!
Maybe I expect too much..!!
I'd never heard of a pin gauge until a day or 2 ago..!!

Thanks for replies

Hey, we've all been there, that's how we learn. Many years ago, before the advent of the Internet and one-click ordering, you actually had to call the mfgs. to order something . Elzie Scott at Wilson was kind enough to educate me on their reamer sizing.

But back to the "tight neck" thing...an inside neck reamer has nothing to do with fitting necks to a specific chamber neck diameter. That's accomplished by outside turning. Inside neck reaming has it's origins from the 'way back days when wildcatters made 22-250 cases from 30-06 and the like.....the necks needed some way to be thinned.

That we can use that same process (inside neck reaming) to address the so-called 'donut' is simply using an existing process to address another issue.
