Normally I use Hornady brand, but these were suggested as a less expensive alternative.
1) They go on same as Hornady.
2) Same accuracy and point of impact as Hornady.
3) $13 cheaper per 1000 than Hornady.
As long as they are made, I'll buy these from now on!

Between myself and a few friends we have used thousands of these checks. I can count on one hand, without using thumbs how many bad ones I've had.
Great crimp

Good has checks at a reasonable price. I was extremely impressed with the customer support that I received from sages. They sent me a sample of their other .30 Cal checks and I will buy those next time as they are as good or better than the gator checks at a lower price. Thanks Sage's!

I use these for .30 WCF on a 170g LFN in a Marlin 336 (microgroove) and Winchester 1894. They work well with Alox lube and a Lee bullet sizer.

I'm completely satisfied with the Gator Gas Checks. I've been using this Checks for Lee 200 grs .309 sized rilfle bullets, which are driven by my charge up to 1700 fps giving best results with my 7,5 x 55 Swiss Ordonance rifle. No fouling inside the barrel and perfect accuracy.
They fit accurate and tight and I had no problems to snap on them without using the press. They are also much cheaper than the stuff of the competitors. I will order this Checks again.

I'm giving it 4 stars since I haven't had my hands on any competitors like Hornady. I ordered they were in stock and shipped rather quickly. I think all in all it took 4-5 days from purchase to on the bench. I've already worked up a load on the 30-06. These gas checks are not the "weak link" for my groupings. At 50yds I can get very close to the same hole with them. 4 in a Dime size. Maybe more but that's all I had of that load. At 2.4 cents a gc, I'm coming back when I burn thru these!
The fit was fine after sizing but some did come off when I had to dissemble some rounds kinetically. New gcs went back on without an issue.
