I have some odd ball loads which I will not describe here, but I put one gas check under the plastic wad and one on top in place of a shot card, then seal it all in with some shot shell sealer.

These checks pop on and don't fall off before they can be set. I use a Star sizer and size down .001 from as-cast from this mould. The checks are just right: not too tight but not too lose. I pick these bullets from dirt berms and water jugs both with the checks still attached.

Great quality and the checks fit nicely on my Accurate mold bullets.

I made an "oops" and ordered regular 40 cal first and they are waay to small for this NOE shank: the old Star attached 'em but shaved a little lead from the shank while doing it. These are just perfect.
