Loading... Please wait...These are our crimp on aluminum .30 / 7.62 mm caliber gas checks. They are made with .015 thick aluminum, so they work very well when sized .309 to .312. We are selling these direct, cut out the middle men and buy right off the press. Made to fit tight on a .284 shank.
Our gas checks are sold in resealable clear plastic bags. USPS flat rate boxes and First Class mail are used to reduce shipping cost.
Sold in 4 quantities: 100 for $5.00, 250 for $8.00, 500 for $14.00 and 1000 for $26.00

Perfect fit in LEE 110gn cast bullet with 2 light coats of Hi-Tek coating.

These gas checks have performed as well as the copper ones. Half the price, using more.

I prefer the Aluminum gas checks over the copper, because they are much lighter and keep the cast bullet closer to the cast weight.

Had never used aluminum checks before they preformed just as well as the copper at less cost . I saw no difference what so ever.

These aluminum .30 Cal gas checks arrived quickly and I was pleasantly surprised at how consistent they are. I cast up some 155 Grain Boolets and the gas checks fit great. I seated them by running them through the .311 sizing die. They came out perfect. I powder coated them with Easton Gold powder which gave me a final size of .312. At the range I was shooting 2.5" groups out of my 10.5" 300 Blackout. YES!!! I'm ordering more. I went through the first 1000 in 2 weeks. I can get a little obsessive with new toys. :-)

I needed some .30 Caliber GC and being a frugal (cheap) old man, I was
unwilling to pay $30.00 plus per 1000. Decided to try 2000 Sage Aluminum GC. Received them a couple of days after placing order, quality was great, clean from bag. fit my bullets nice and tight. I'll buy more when I need them. I highly recommend them.

I have found all the gas checks I have bought from Sages to be of very high quality.

These gas checks did a great job in mid range cast loads. The price is excellent. I'll be ordering more soon.

Quality product for a reasonable price.
I will be buying more of this and other Sage's products.
Shipping was incredible.
