Tolerances

[DevilDawg]

In the reloading world we throw around a lot of dimensions such as overall case length. As an example a manual will say to trim a 6.5 remington case to 2.025" but it does not specify any tolerances, such as +/- .002 etc.. In the machine/manufacturing world there are few machines that can hold a dimension dead on. And with our hand operated reloading tools I would say it is impossible to hold a consistant dimension.

Sooooooooo, in your opinion, what do you consider an acceptable tolerance when trimming cases?

use the tool described in the post and do not worry about anything because it has zero tolerance everytime.

Cheap to boot!

I completly agree with POP in fact that is what I use to trim my cases. Never have any differences in case length.

I have been reloading for a long while now, probably more than 45 years. I have struggled with lots of different methods of case trimming. None of them were all that great.

Lots of folks on here swear by the Lee trimmers, I am not so impressed. I have Forster trimmers, Lyman trimmers, etc. etc.

BUT, a while back I bought what I think is the best case trimmer ever sold. It is a product sold by Sinclair. It is called the Wilson/Sinclair Ultimate Case Trimmer. It is not cheap, they sell for $139.00. It is worth every penny!!! Sinclair took a Wilson case trimmer and added their own stand and a micrometer to it. It works better than any other product I have tried.

This trimmer does not use pilots, it uses case holders. One holder will do all the Weatherby cartridges from .257 to .340. One holder will do 25-06, 270 Winchester, 30-06, etc. You get the idea.

With the micrometer on this thing you can just dial in what length you want and you will get it EVERY TIME! I have checked and checked cases trimmed with this thiing. If you set it on 2.50 inches you will get a case 2.50 each and every time. I love this thing.

I used to just hate trimming cases. I have had this trimmer for over a year and still find myself looking for excuses to trim something.
