  1. Will review later 5 Star Review

    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.

  4. Aluminum checks are money savers. 5 Star Review

    Posted by on May 21st 2017

    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.
