Confused(28/08/2012)
I'm not quite sure how this is product is supposed to work. It says it's for use on fired, un-resized cases, and that it's .0025"-.003" oversize. Well, what if my chamber throat is slightly oversize? Or what if I've had a match chamber cut in a customer barrel, and the case neck doesn't expand as much as expected? Either it cuts too little, or too much, in either case. Why not make it .001" UNDER-size? That way I can re-size my brass, ream the neck, and there's a slight interference fit. Once the bullet is seated, the neck tension would be uniform no matter what. As it is, there is an uncertainty...and because I can't wrap my mind around it, I'm not buying it. I'll use something else.
If you use it correctly, works perfect(01/11/2012)
The Inside Neck Reamer is not a uniformer it is designed for use on cases that have been reloaded several times and you have excess material build up in the case neck.It will "reset" your cases to factory wall thickness. You can also buy a reamer that is too the dimension you want or Sinclair stocks some special sizes that are .001 to .002 under bullet dimension. Just need to use it correctly.
works great(05/06/2010)
this neck reamer is very easy to use,very high quality as to expect from wilson.i shoot a 6mmrem and this makes things more consistant,makes neck tesion the same case per case,excellent product.
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.
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.
