If you're loading precision 22-250 Remington and want tight, consistent brass, the L.E. Wilson 22-250 Case Gage is one of those small tools that earns its spot on the bench fast. It's a one-piece steel cylinder machined to SAAMI minimum chamber dimensions, so you can drop in a fired or sized case and see right away whether your shoulder bump and trim length are where they should be. No moving parts, nothing to calibrate, just a reliable reference you'll reach for every loading session.
L.E. Wilson has been building reloading tools in Washington state for the better part of a century, and the case gage is the product that started it all back in 1935. The whole idea came from solving case-separation problems, and that same purpose holds today. Oversizing bottleneck brass is one of the easiest mistakes to make, and this gage shows you exactly how far back you're pushing the shoulder so you can dial your full-length sizing die in with confidence.
Using it is straightforward. Drop a fired case in and measure the headspace with a caliper or depth micrometer, depending on whether the case sits high or low in the gage. From there you can slowly adjust your full-length sizer until you get that one or two thousandths of shoulder bump below your chamber's headspace. That little bit of control is what keeps your brass alive longer and tightens up your groups. Once the case is sized, set the gage head-down on a flat surface and sight across the top to check min and max trim length.
This gage reads min/max case length and min/max headspace, giving you the two measurements that matter most for safe, repeatable loads. One thing worth knowing up front: it does not measure body diameters, so it's built as a reference for establishing your trimming and full-length sizing baseline rather than a full body check. For most reloaders chasing accuracy with the 22-250, that's exactly the information you need. Made in the USA and built to last.
Drop a fired case into the gage and measure the headspace with a caliper or depth micrometer based on whether the case sits high or low. Then slowly adjust your full-length sizing die until you see roughly one to two thousandths of shoulder bump below your chamber's headspace. This gives you a resized case that fits your chamber without overworking the brass.
No, this gage does not measure body diameters. It's designed to check overall case length and headspace so you can establish a reliable baseline for trimming and full-length sizing. For most precision 22-250 reloading, those are the two measurements that matter most.
Yes, you'll want a caliper or a depth micrometer to read the actual headspace and trim measurements. The gage gives you the reference surfaces, and the caliper or micrometer gives you the precise numbers. L.E. Wilson also makes a case gage depth micrometer designed to sit right on top of the gage if you want to streamline the process.
Yes, this specific gage (CG-2250) is cut for the 22-250 Remington cartridge. L.E. Wilson offers these one-piece case gages in most popular rimless calibers, so you'll want a separate gage for each cartridge you load.
