I dunno what else anyone could expect from a copper gas check. They fit. They work, and the quality is nothing less than as they should be. Using on an old #311359 spire point mold. I will be ordering more again. Sage Outdoors delivers.

This is the 1st bag of the .30 cal gas checks I have purchased from Sage's but I have been using their .35/.38/.357 size Gator checks for quite a while. They work great, accurate, no leading. Every bit as good as Hornady & other brands. But cheaper. I bought these to use on my 308, 30-30, & 300 BO, (both suppressed and non-suppressed) as well as my 30 M1 Carbine.

Well made and fit the Lee cast .309 115 grn bullets very well. Price is excellent although if you are ordering for UK delivery be aware of import tax to be paid.

I use these on my custom molds from mountain molds. And man do they hold well. Awesome

These go on great using my Lee sizing die for my 30-30. Gas check appears to hold up and stay put at velocities tested up to 2300fps shooting through 3/8” rubber belting for target backer. Perfect fit with no leading, far better than the copper fouling shooting jacketed ballets in my Winchester 64A.
Fast shipping and great pricing!

If you on the fence just buy them great gas checks you will find solid material solid customer support and service. Can't say enough good things about sage and gator checks

Normally I use Hornady brand, but these were suggested as a less expensive alternative.
1) They go on same as Hornady.
2) Same accuracy and point of impact as Hornady.
3) $13 cheaper per 1000 than Hornady.
As long as they are made, I'll buy these from now on!

Between myself and a few friends we have used thousands of these checks. I can count on one hand, without using thumbs how many bad ones I've had.
Great crimp
