Bumping the shoulder

When bumping the shoulder with the Redding body die how do you measure the case to insure you have the .001-.002" bump?

Re: Bumping the shoulder

It would be nice if you had a "widget". I always make one for my customers when I chamber a BR rifle for them. It is a peice of bbl. that I run the reamer in just enough to get the neck and shoulder part of the chamber. After de-capping a fired case you insert the case in the "widget" and measure with the calipers. Measure again after sizing to determine amount of "bump" I also face off the other end about .020" past the mouth of the neck for a quick visual length guage.

Re: Bumping the shoulder

Redding makes a case mike for specific cartridges that will work for that cartridge only.

Also you can use the stoney point headspace guage tool, www.sinclairintl.com part# HK-66 is a body and five bushings. $35.65 With the body and five bushings, you can measure any case.

Yes this is what I do--removes any and all doubt!!!! The trick is to have the "widget" made when the barrel is installed!

Re: Bumping the shoulder

It is nice to have the "Widget" made at the time of barreling but, not critical. If you have a cartridge with a 30 degree shoulder (or any other angle for that matter) you can set the compound at that angle and make a "Widget". It doesn't require a reamer.

DocEd's got the right idea! I hold the size on mine so that when I measure a case I subtract 1" from the reading, it gives me the actual headspace measurement. I've made one for every cartridge I reload.
