  1. Excellent fit and finish 5 Star Review

    Posted by on Mar 6th 2024

    These are as advertised and a great value in this economy. The fit and finish as well as the consistency is excellent.


  2. Uniformity and function are spot on. 5 Star Review

    Posted by on Nov 16th 2022

    I first tried them on a unique "footed shank" .40 application and they are a little too tight. Were it not for that foot on the shank they would do nicely. Work well on a .41 shank application. I found no malformed checks and while I have not counted it seems they do throw in a few extra with each order.


  3. Using these gas checks in my .410 shotgun 4 Star Review

    Posted by on Jan 15th 2020

    I have some odd ball loads which I will not describe here, but I put one gas check under the plastic wad and one on top in place of a shot card, then seal it all in with some shot shell sealer.


  4. Perfect for NOE 403 198 WFN 5 Star Review

    Posted by on Oct 11th 2019

    These checks pop on and don't fall off before they can be set. I use a Star sizer and size down .001 from as-cast from this mould. The checks are just right: not too tight but not too lose. I pick these bullets from dirt berms and water jugs both with the checks still attached.


  5. Great checks 5 Star Review

    Posted by on May 16th 2019

    Great quality and the checks fit nicely on my Accurate mold bullets.


  6. Perfect fit for my NOE mould. 5 Star Review

    Posted by on Mar 25th 2018

    I made an "oops" and ordered regular 40 cal first and they are waay to small for this NOE shank: the old Star attached 'em but shaved a little lead from the shank while doing it. These are just perfect.
