  1. Works for my .32 Remington 5 Star Review

    Posted by on Sep 11th 2018

    Got these for a .32 Remington bullet (.321") and they work fantastic. Checks were consistent and well made. They fit perfectly - crimped on securely and neither came off or were loose enough to spin. I would definitely recommend these.

  2. 8mm aluminum gas checks 5 Star Review

    Posted by on Aug 3rd 2018

    I took 8mm Mauser cast bullet ammo to the range to compare these aluminum checks side by side with Hornady copper checks.
    I couldn’t see any difference in the performance. Accuracy was equally good.
    And I saved a little $$ compared to the Hornady product.
