      I’ve been sizing my checks for 25+ years because they then fit completely flat against the bullet base and square to the bullet. That they are then an easy slip fit on the shank is a big plus. Amazing that Al can put out such a high quality tool at this price. Thanks Al.

        To be totally honest the idea originated with Rick.  Someone else just took the concept and modified it, turned it upside down so to speak.

          Got mine today. I found that it works better if the die is loose in the press so it can sort of self center. I may have to mount a press upside-down in order to see what I am doing. Other than that, another fine tool to play with!

            There really isn’t anything to center.  Put the ram fully up, thread die in until it just contracts the ram punch.  You are now ready to go to work.

            An upside press would work but the check then needs to be centered under a moving punch.  The way it is designed it lets the check get placed on the punch then expanded.  This keeps things like fingers out of the way of stuff that pinches.

              hmmm- tried that- didn’t work. Two main issues: Using a RCBS Rockchucker, I can’t see to keep the check centered on the ram (Hornady crimp-on checks). I tried using an upside-down Lyman seater die, with a flat top- I could thus see what was happening. The main issue seems to be that the check does not want to stay centered on the post. I probably need to round the top edge of the ram part just a bit. This is the case with both .30 and.358 posts. Another issue is that most of the checks got stuck on the post, and it was almost like suction rather than friction. I’ll keep playing with it but I prefer the older NOE gas check seater die.

                Too much of a flare  can actually weaken some gas checks causing them to fall off in flight. You should flare a gas check just large enough to snap on with some slight resistence…do not over flare them checks.

                Gas check quality (all manufacturers) can vary from lot to lot and will make a difference in accuracy.
