These are our crimp on .30/7.62 mm caliber gas checks that size to .314 max. They are made with .015 thick aluminum, so they work very well when sized .309 to .314. 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.

I have not had a chance to even get out to try these gas checks but I have looked at several of them and measured a few also, they seem to be pretty consistent and weights are also. I plan doing an update later but from what I see they look like they will get the job done.

I've used other brands in the past. never again. Sage's fit perfectly, snap right on my Lee C312 cast bullets.

If you shoot a lot of gas checked bullets you know that the check adds tremendously to the cost. Aluminum checks will save you a few bucks. Using 2 different Lee moulds and sizing to .310" in a Lyman 450 and then running them through a Lee push thru die to bring them to .309" left them crimped firmly on the bullet. I resisted aluminum checks at first, but after using them awhile I'm sold on them.
