The aluminum gas checks used on my Lee 440gn.bullets shot accurately out of my Encore 15" barrel,I was getting keyholing before and the aluminum gas checks stopped the keyholing ,.......I didn't want to pay fifty bucks for Hornady copper checks to find out if this would solve my problem and I found Sages website and found out I could buy 100 aluminum gas checks for 7bucks and give them a try,......giving me a selection for how many I want or need at a time makes me one happy customer!

These Aluminum gas checks are a real bargain if you cast your own projectiles. I use them for a variety of calibers, and have had no issues with feeding or ejection. They seem to be effective, while not adding undue weight to the projectile, and that matters a lot to precise target shooters like me. Recently I purchased some 50 cal gas checks, and they work flawlessly for my Beo target rifle, really very happy with my purchase, and without hesitation, I would buy them again over any other manufacturer.

I put these on hard cast 440gr LFN bullets I cast from a Lee mold. They fit just right and work well. Sized to .501 thru a Lee sizer die. I shoot these in a 500SW H&R Handi-rifle. I mainly want to not lead the bore, and also be able to push the bullets a little harder and get a little extra velocity. These GCs do the job for me. My loads are below factory max power and velocity, but they are plenty accurate and potent.
