  3. I would buy these again 5 Star Review

    Posted by on Nov 23rd 2023

    I recently found a cigar box full of .30 cal 200 gr cast bullets and was curious if this would be something that I would want to invest in. I found these aluminum gas checks at a good price and decided to give them a try. They worked just as expected and that's all that I can ask of it. I would buy them again!

  4. These Gas Checks Solved a Major Problem 5 Star Review

    Mr Sage recommended these when I had a problem with one mold that made slightly oversize shanks. They fit perfectly and stayed mounted. They enabled me to continue using the mold instead of sending it back to the maker.

  8. 30 caliber checks for my 32/20 Blackhawk 5 Star Review

    Posted by on Jun 20th 2022

    I was very surprised how well the aluminum gas checks worked on my 32/20 bullets in my Blackhawk Buckeye. I've always just used copper in the past but decided to try the aluminum & they worked great, thanks for a great product.

  10. Excellent product! 5 Star Review

    Posted by on Apr 13th 2022

    Been using these for years with the Lee .30 caliber bullets. They fit great and cost less than others. Also, there is no need to use a separate crimping tool, they crimp in place just by running them through the sizing die as normal.
