  1. First time buyer 5 Star Review

    Posted by on Apr 16th 2021

    After waiting 6 months for them to become available, I finally received my gas checks. I can't say it was worth the time, but they weren't available anywhere else either. I have used Lyman and Hornady gas checks in the past and these are just as good and at a bargain price. I know where to go for my next gas checks.


  2. 303 tall checks for the 327 federal mag 5 Star Review

    Posted by on Jul 2nd 2019

    I use these checks on a 112 gr bullet from an accurate mold. Bullets are used in a 32 h&r mag and ruger 327 mag, sized at 314 they really grip the shank. Accuracy has been great.


  3. 303/7.62 .017 gas checks 4 Star Review

    Posted by on Oct 9th 2018

    They work fine but initialally they went on the bullet shank a little loose on a mold from accurate molds. But after sizing they were good and tight . Maybe a little more research on the better mold manufacturers shank diameters could tighten things up a little bit. That being said i know manufactuing specs for different alloys producing consistant shank diameters is problematic. All in all it worked for me. Louie.

    Shamus: they have a .283 cup size for a tight fit, your shanks should be at least .284.
