  1. 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.

  3. 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.


  4. Great gas checks 5 Star Review

    Posted by on Jan 20th 2022

    Bought over 5k+ of these gas checks and they installed and crimped on no problem on the heel of a powder coated lee .312" 160 grain cast bullet using the lee .311 sizing die. Works great with sizing with the .309 sizing die as well. I've ran these in semi-autos, and clocking them 2000+ fps using WW lead/range scrap hardness lead with decent accuracy and no leading. Well worth it!

    When sizing, ~.004"+ under, I noticed a bit of flashing being produced around the checks, but they don't seem to affect performance. To alleviate this, I either size and gas check in two steps (i.e. pass through .311 then .309) or apply a tad bit of case lube so the cast will pass through the sizer a bit easier. This is by no means a problem with the gas checks themselves.


  5. I think better than Copper 5 Star Review

    Posted by on Jul 10th 2021

    love these, this is my second order and there will be a third soon. I put these on reduced loads military rifles, Arisaka, Mosin-Nagant and Krag. But I use the copper ones in 32 caliber, because not made yet. I use all Lee molds.


  6. My new go to .311 gas check 5 Star Review

    Posted by on May 12th 2021

    did a test with these vs cu found no difference in point of aim. Both cu and al checks are premier better than the other guys with the red boxes. As I shoot 200 to 300 rifle round various cal, I will soon be buying more, I like to test different powders and loads on .308, .311, .323, .329, .45, .458
    Just hope we can get some inventory. Since finding Sage's Outdoors I cannot be happier. Thank you for a fine product at reasonable prices. terry

    Posted by on Nov 1st 2020

    They are just as good as copper gas checks but lighter. This makes the bullet closer to it cast weight.
