  1. prefer over copper gas checks 5 Star Review

    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.


  2. BOOM BOOM goes the volley 5 Star Review

    Posted by on Oct 23rd 2020

    Get it, use it, enjoy it. I personally chose this check for .30 cal needs as it gives a hint of room on .309 sized rounds powder coated. I cast .312 and size to .309 after powder coating. The checks fit very snug, crimp well.
    My reason for the choice of 312 casting is I get .311 to .314 drop. This I load in 30-06, 300Sav, 7.62x54R, 7.62x39, 7.7Jap, 300Blk, 308 all of which shoot great, 90%+ weight retention on impact. I know this would not happen with out a great gas check.


  3. great value 5 Star Review

    Posted by on Oct 6th 2020

    i use these with 30-30 and 7.62x39 and they work great. i see no difference in the aluminum and copper except the cost. i am able to use near max loads with no leading. highly recomend


  4. Exceeded Expectations 5 Star Review

    Posted by on Sep 13th 2020

    When I couldn’t get gas checks from my normal supplier, I decided to give these a try. Not only are these one half the price, they shoot great too. An added bonus is that on my powder coated bullets, they are just a little bigger. They fit on bullets that my previous checks did not. This has reduced my reject rate to less than 1 percent. Fantastic product and the service was great. I highly recommend.


  5. Love this item! 5 Star Review

    Posted by on Aug 27th 2020

    If ound these Aluminum gas checks to actually be easier to use than Copper or Brass checks, especially when attaching them using the press-mounted Lee Bullet Sizer. These checks are great for the cast bullet loads I'm using in .300 Blackout, as the Aluminum is not as hard as the other types, thus actually allowing slightly higher velocities without increasing chamber pressure.
    Would I recommend these? Definitely yes. These checks do an excellent job, and are easier on the wallet than other types. And the price? It makes buying those "do it yourself" gas check maker kits not really worth the expense of buying one.


  6. Best deal out there for gas checks! 5 Star Review

    Awesome quality and service from these guys!I will buy again!


  7. AL .30 GC 5 Star Review

    Posted by on Aug 20th 2020

    Using these first on a 155 gr 762x39 bullet Spire point casting at .312, I always push my GC on to base prior to running up a Lee sizer ( how these are being done) but using my Lyman sizer I just put GC in top with bullet and run through and add grease. These GC work fine both ways


  8. Perfect Fit 5 Star Review

    Posted by on Jul 26th 2020

    I used these on a Lee 762x39 bullet. They fit perfectly even after a light powder coat.


  9. They work! 5 Star Review

    Posted by on Jul 6th 2020

    I used some "homemade" aluminum checks and they were junk. They would fall off. I tried these mainly because the copper were out of stock. They work! They go through the sizer more easily and for me they centered better and they stayed on. I found gas checks in the berm at 100 yds so they stayed on the bullet all the way thru the target backing.


  10. As goo$ as any 5 Star Review
