These are our crimp on .30 / 7.62 mm caliber gas checks that size to .312. They are made with .015 thick aluminum, so they work very well when sized .309 to .312. They are made like our .015 copper gas checks, nice deep clean formed gas checks. 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. Shipping is based on each item's weight. USPS flat rate boxes and First Class mail are used to reduce shipping cost. Most orders ship in one business day Monday through Friday.
Sold in 4 quantities: 100 for $3.95, 250 for $5.75, 500 for $10.25 and 1000 for $18.50.

It's a gas check. Big deal, right?
It's a small thing but one that's well made. Its cleanly made w/ never a ragged edge. The diameter is extremely consistent. They got on easy and fit tight. They're generally still attached even after hitting a steel target.

These fit all of my molds from .308 to .315 can't beat it. Save time I can now use reloading or another trip to the range.

I have loaded and fired approx. 300 rds using these checks on NOE 310-210-FN-AR1 used in a M1 and a Finn39.at 2200 fps.
They do at least as well as them fancy brass checks from Nebraska and fit and stay better.
Also used on Lee 313-185 in the Finn 39. 3" groups at 100 which is as good as I can do with anything w/open sights.
And finally used on RCBS 308-165SIL in the 30-06 at up to 2500 fps, again 3-4" at 100 which is the limit of my ability.
I'm very happy, they fit very well and stay crimped.

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.
All prices are in USD.
