Gas checks are very uniform in size and thickness , fit the base of the bullet well when pressed on and sized, will definitely purchase again.

I've only been using gas checks since the late 70's, but learned fast I didn't like Lyman gas checks. These seem to be better the Hornady. Do recommend them.

I purchased the .30 cal copper checks, used them with a cast .309 Lee mold, the fit was perfect. Customer service was friendly and personal with outstanding shipping.
I will purchase them again, thanks Sage's

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.
