  1. Nice .30 Cal Gas Checks .017 5 Star Review

    Posted by on Oct 15th 2020

    I used these gas checks on the Lyman 311359 lead bullet. I bought the .017" thickness, and they work great !! I figured get them in .017" because I didn't know what was the next bullet I was going to use them on. They crimp on nice using the Lee .308 sizer die. If I need more gas checks of any size, I'll buy them here as well. Happy Shooting !!

  6. Great gas checks!!!! 5 Star Review

    Posted by on May 19th 2020

    I ordered these gas checks on the advice of a fellow reloader. He said they were just as good or better than the Hornady gas checks we had used in the past!!!!!!! After receiving these checks from Sage's Outdoors, I have to agree. Great quality, fit is perfect, I love the thickness of the checks I selected for my .311-155 2R boolits.

    Great product, and I will definitely order more!!

    They work just like the Hornady's that I have used in the past.

  8. Great, proper fitting gas check for my 7.62X54R (Lee C312-185-1R mold). 5 Star Review

    Posted by on Nov 13th 2019

    I e-mailed the owner and asked what he recommended for this new bullet of mine sized to .314. He recommended the .30 / 7.62 MM CALIBER .017 COPPER GAS CHECK and it fits like a glove. I have used several other Sage's gas checks, both copper and aluminum, and they have all worked perfectly.
