Thick necks can cause high chamber pressures and erratic shooting. Wilson neck reamers remove excess neck material to insure adequate clearance exists between the case neck and the chamber. Also, these reamers can be used when forming wildcats from a parent case. Reamers are used in the Wilson trimmer in place of the trimmer cutter. Standard reamers are sized for use on fired, unsized cases and measure .0025" - .003" larger than bullet diameter. Custom size reamers can be ground (allow 6-8 week delivery).

Works well if used correctly 30/01/2017

The standard reamer is not made to remove doughnuts. Standard size reamers are to be used on FIRED cases that have been reloaded several times and have material build up in the case neck they finish out at about .002" over bullet diameter. If you are looking to remove the doughnut with the Neck Reamer make sure you order a special diameter reamer. Sinclair stocks several special sizes. If the reamers are used correctly, they can be very useful in resolving several different issues in the case necks.

Will Not Remove Neck "Donuts" 15/05/2015

I purchased this inside neck reamer to remove case neck donuts in my 6xc brass (formed from 22/250 brass). Many people recommended inside neck reaming as the best way to remove the donuts and said that Wilson's inside neck reamer was the best available. Unfortunately it won't cut through the donut and jams solidly when it hits it. The donuts are just too tough for the reamer. Unfortunately I have wasted my money on this product for the purpose of removing case neck donuts. If you have the dreaded donut problem look for another solution.
