  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.

  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.
