Case gauges

How important/critical is the use of a case gauge? And is a case gauge more important with rifle or pistol cases? Thanks...

RE: Case gauges

If you have multiple firearms that you're shooting the same caliber or semi autos, the case gauge helps feed failure. If it's just one gun then you can test with the barrel.

That being said, it can also help determine inadequate crimp, cracked cases that won't fit, and other issues.

So if you don't mind an concessional feed failure then you can get by without one, but I don't reload any caliber that I don't have a gauge for.

RE: Case gauges

It is unnecessary to use a case gauge with 45 Auto Rim. This round is a straight wall case used exclusively in revolvers. The length is generally not an issue because the finished round does not head space off the case mouth. So when you first set your resizing decapping die in the toolhead. Resize a few cases and then insert the resized case within the cylinder to make certain it is resized sufficiently. Once that is accomplished, work the rest of the stations and, as a revolver round, use a light crimp to prevent the loaded bullet from moving with recoil.
