    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.

  6. More than worth every penny 5 Star Review

    I'm probably not the biggest buyer of Sage's checks, but I've used enough of them to have an opinion. I also appreciate his quick and reliable response to orders. Now to the checks.

    I've fount these 30 caliber checks to fit all my bullets, especially powder coated, easier to crimp on the base than Hornady checks, on 30 and 31 caliber bullets when run through my NOE nose-first sizers. They seem a bit softer than Hornady and even Gator checks when judged by the force required to size and crimp in one pass on a coated bullet. Also, I've yet to experience even one failure to crimp and stay on in at least a few thousand bullets- doesn't get better than that.

    Big bottom line: by today's standards, price, quality, and service meke these a great value.
