  1. Great gas checks 5 Star Review

    Work great with my cast .308 bullets.

  2. Great product 5 Star Review

    Posted by on Aug 19th 2024

    Have used Sage's checks for some time now, currently use the 22, 6mm 6.5 mm, 7mm and 30 caliber checks without any issues. Would recommend wholeheartedly.

  3. Outstanding Product 5 Star Review

    Posted by on Apr 29th 2024

    First time using Sages Outdoors .30 caliber gas checks. Found they were a little shorter than the Hornady gas check I was using, however, the length of the Sages .30 caliber gas checks made no difference in the condition of the bore of my Mossberg .30-30 after two range sessions, and the price is right. Incidentally, I cast bullets in a Lyman #311041 double cavity and a single cavity mould., with a velocity in the 1400 fps to 1450 fps range. Outstanding 5 Star product. You bet, and when I need more .30 gas checks - I will order from Sages Ourdoors..

    They work great.

  5. Outstanding product 5 Star Review

    Posted by on Jan 8th 2024

    Myself and my shooting buddies have fired thousands of these gas checks, and they are outstanding.
    These are ever bit as good as the Lyman or Hornady check at a lower price.

  6. Comparison with hornady 5 Star Review

    Posted by on Oct 11th 2023

    I started using these copper gas checks about six years ago with 220 grain bullets in my 30/40 Krag rifles and 200 grain bullets in my 35 Remington both with velocities of about 1850 fps. To my knowledge I have never had a gas check seperate in flight and I find these to crimp better than Hornadys and seat more easily.

  7. Used on 30 cal cast bullets 5 Star Review

    Posted by on Jun 20th 2023

    Gas checks fit well and crimped on easily. I used them on 160 gr .312 Lee bullets for 7.62 x39.

  8. A must have. 5 Star Review

    Posted by on Mar 18th 2023

    I've bought twice from Sage's.
    Every cup has been perfect.

  9. Great gas checks 5 Star Review

    fit bullet bases well, nicely made, excellent price, I LOVE them!

  10. Excellent quality and service/shipping 5 Star Review

    Posted by on Oct 19th 2022

    I have used these gas checks,(GATOR CHECKS) for several years. This product is well made, fit cast bullets well and help prevent gas cutting of lead bullets shot at velocities exceeding 1600 fps. Al around good product at a good price from a darn good company.
