Description
If you're loading for the .35 Remington, this little steel cylinder from L.E. Wilson belongs on your bench. It's a one-piece, non-adjustable case gage built specifically for the cartridge, and it does two jobs that matter most to anyone running a full-length sizing die: checking headspace and confirming overall case length. Drop a fired or resized case in, take a quick look, and you know exactly where you stand before that brass ever sees your press.
L.E. Wilson has been machining reloading tools for decades, and the case gage concept actually goes back to 1935, when founder Sam Wilson came up with it to help a fellow shooter beat a case separation problem. That same idea still holds up today. The biggest mistake reloaders make is oversizing their brass, pushing the shoulder back too far and overworking the case every cycle. This gage lets you measure a fired case, then slowly dial in your sizing die until you get just a couple thousandths of shoulder bump. That small adjustment is what keeps your brass in service longer and your rounds chambering smooth.
Checking Headspace With the 35 Remington Case Gage
Using it is about as straightforward as reloading tools get. Seat a case in the gage, set it head-down on a flat surface, and look across the top. The milled high and low steps show you the maximum and minimum trim length at a glance. For headspace, a caliper or the matching Wilson depth micrometer tells you whether the case is sitting high or low in the datum, which points you toward exactly how much to size.
Why the CG-35R Earns Bench Space
The .35 Remington is a lever and pump favorite that's been around since 1906, and quality factory brass isn't always cheap or easy to find. That makes getting the most life out of every case worth the effort. This gage doesn't measure body diameter, and it isn't meant to replace your caliper, but as a fast, repeatable check on headspace and length it's hard to beat. Precision machined, made in the USA, and built to outlast just about everything else in your loading room.

Frequently Asked Questions
What does the 35 Remington Case Gage actually measure?
It measures two things: case headspace, from the datum line to the case head, and overall case length. Those are the two dimensions that matter most when you're setting up a full-length sizing die and deciding when to trim. It does not measure body diameter, so you'll still want a caliper on the bench for that.
How do I use the CG-35R to set my sizing die?
Start with a fired case and take a headspace reading in the gage using a caliper or the Wilson depth micrometer. Then size the case and recheck, slowly dialing in your die until you see roughly a .001 to .002 inch drop in headspace. That small amount of shoulder bump sizes just below your chamber, which chambers reliably and avoids overworking the brass.
Is this an adjustable gage?
No, the CG-35R is the regular one-piece, non-adjustable style made specifically for the .35 Remington. The adjustable version is a separate product intended for belted magnum cases. For a rimless cartridge like the .35 Remington, this fixed gage is exactly what you want.
How do I check trim length with the gage?
Seat your sized case in the gage and set it head-down on a flat surface. Look straight across the top and the milled steps show you the maximum and minimum trim length. If the case mouth sticks above the high step, it's time to trim.
