1. I would buy these again

   Posted by Unknown 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!

2. These Gas Checks Solved a Major Problem

   Posted by Ed on Apr 1st 2023

   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.

   I have used many thousand of Sage's gas checks and find the quality of this product unmatched.

   I have used about 10000 of these and not 1 was bad, also I have used about the same number of Sages CU checks with equal results

6. 30 caliber checks for my 32/20 Blackhawk

   Posted by Richard Thompson 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.

8. Excellent product!

   Posted by Lance J Hale 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.

9. Great gas checks

   Posted by guzma393 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.

10. I think better than Copper

    Posted by terry 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.
