So I have some of the old ideal gas checks. I haven't used them yet, and have been researching their quirks. I've seen where people just use them and deal with the occasional off shot when they come off mid flight. And where people glue them on.
Well, what about crimping 30 caliber gas checks on with a 7mm lee FCD. My preliminary research shows 7-30 waters has a neck of .306 so that die would be just right. Then fashion a rod inside the die, maybe on a solid shell holder, to position the bullet so it crimps the top edge of the gas check into the shank and boom, crimped on old style checks. Fast and repeatable.
Opinions?
