One piece gage that will check overall length to indicate the need for trimming, datum to head length to assure correct headspace and to prevent over sizing. Available for most popular rimless cases. The Cartridge Case Gage was designed with safety in mind and was invented by our founder Sam (L.E.) Wilson in 1935 after a fellow shooter approached him for help in solving a case-separation issue. The gage allows you to see just how much you are sizing back your shoulder on your cases.
This is best done by following the steps below.
Note: Does not measure body diameters. This gage is intended to be used with fired cases to determine a basis for full length sizing and trimming.
Available January 2019 -Ever wonder if your reloads meet min chamber dimensions? Then this is the gage for you. Made with the same tight tolerances you have come to expect from all your Wilson Tools. Best used if you are loading ammo to work in multiple gun chambers of the same caliber. We recommend using this in conjunction with the Regular Case Gage to prevent over-sizing. Gage verifies Min Chamber Dimensions and OAL for SAAMI. NOTE: Check with your bullet manufacturer to verify OAL this will vary depending on what grain and style bullet you are using.
Min Dimensions Gages are made to SAAMI specifications for Min Chamber. SAAMI Min Chamber specs are slightly LARGER than Max Cartridge. The purpose of this gage is to check your reloaded rounds to see if they meet Min Chamber Specs. Therefore, if your rounds do not enter the Gage, then this is pointing to an issue with your reloaded round against SAAMI specifications.
On the other hand, if your rounds DO enter the Gage, but DO NOT chamber in your gun. This points to you having a very tight chambered gun and would assume either an improperly cut reamer or a chamber that was cut below Min Chamber Dimension headspace.
This does NOT mean that your round will not chamber in your specific gun's chamber. This only means the round DOES NOT meet SAAMI Min Chamber dimensions and is telling you to take another look before deciding that your round is good to fire.
Reasons to use the Min Dimension Gage
1) You want your reloaded rounds to chamber in a variety of guns
2) You want to check for uniformity of your rounds against SAAMI specifications
3) You want to pinpoint issues with your reloaded ammunition
4) You want a quick check to see if you are under MAX SAAMI COAL
5) You want to check factory ammunition you have purchased
We recommend using the Regular Case Gage for bottle necked cartridges to assist you determining how much to trim and push back your shoulder to suit your chambers headspace.

The Cartridge Case Gage was designed with safety in mind and was invented by our founder Sam (L.E.) Wilson in 1935 after a fellow shooter approached him for help in solving a case-separation issue. The gage allows you to see just how much you are sizing back your shoulder on your cases. This is best done by measuring a case in AS-FIRED condition. Take a measurement. Resize case on current die setting. Then place back in the gage to see just how much you are sizing the shoulder back. Finally, adjust sizing die accordingly. After sizing your cases, there is a good chance the brass will lengthen. The gage will also check min/max case length and will point out the need for case trimming. This is an essential tool for every reloader.
