    Checks have worked very well on all My 30cal bullets from Lee molds.

    I seat them with a Noe push through sizer before Powder coating then size again...

    Will be buying more!

  4. Good value for the budget reloader 4 Star Review

    Posted by on Jun 27th 2018

    I'm a reloader of 7.62x39 using cast bullets. I've used copper checks before and decided to give aluminum a try. Size is accurate, fit is precise but these do not grip well on harder lead alloys such as Linotype or Foundry. I experienced checks being pushed off during sizing due to the edge of the check not cutting into the bullet shank. I was, however, using a Carnauba based bullet lube. The increased hardness of the lube may have been the primary cause of push-off. Checks that pushed off were easily reseated without issue. Bullet accuracy was not affected by push-off and I did not see where any checks separated from the bullet during test firing.

    Final analysis: With these checks installed on a 140gr 0.311" bullet, I have the accuracy to hit center on a 2" steel pipe at 100yds with only a red dot sight coming from a 7.62x39 AR platform.

    I recommend these to any reloader who's budget conscious and needs a quality gas check for their cast bullets.

  5. Will review later 5 Star Review

    Posted by on Feb 15th 2018

    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.

  8. 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.
