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

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

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.

Great value and quality

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.
