Sinclair Chamber Length Gage Reviews & Ratings

SINCLAIR CHAMBER LENGTH GAGES

The Sinclair Chamber Length Gauges are designed so the handloader can determine the true length of his rifle's chamber when measuring from the bolt face to the end of the chamber's neck. This measurement will tell you how much excess case length your chamber may have over published trim lengths in reloading handbooks. The Sinclair Gauges are inserted into a fired, unprimed shortened case and then chambered into your rifle. The insert pushes back into the case when it contacts the end of your chamber. You then extract the case and measure the overall length. The gauge is made of 12L14 soft steel so it will not damage your chamber. Step-by-step instructions accompany each gauge. The gauges can be used over and over again. The differences between published trim lengths and the actual length of your chamber can be quite significant. You could be over trimming your cases by .030 inch or more. NOTE: The 22 caliber gauge will not work on thin-necked cases such as the 22 Hornet, 218 Bee, or cartridges based on these cases. The 30 caliber gauge will not work on the 30-30 Winchester. None of the gauges listed will work on tight-necked chambers except for the G-243T. Should not be used in handguns, semi automatic rifles, lever actions rifles and pump action rifles.

Sinclair

I had to remove most of the neck and then resize what remained for this to work.

Works - with modification

The chamber length gauge for .223 calibers works, but the shoulder is much too thick. Without modification, you need to remove almost all of the neck of a case to allow enough space for the gauge to not bottom out. Problem with this is that there isn't enough neck left to keep the gauge in line with the bore. I had to turn down the .224" diameter part to about 1/3 of the thickness that it is manufactured at so that it would work properly. Other calibers worked outstanding, but this one needs some modification to work.
