I was curious to see how they worked so I ordered one this past spring. He was kinda slow; it took over two months IIRC.
I had ordered one in .30 cal since I shoot a lot of that. However, a broken collarbone slowed me down and I discovered about 3 thousand forgotten Gator checks as well as the four thousand Hornadys on hand.
So, when it arrived, I didn't have much enthusiasm for it. I made a few out of pop cans, but they were too thin and then I forgot about it.
Later, I started playing with my NOE .375 moulds and their gas check shank was a hair too large to accept Hornady checks without a lot of effort. So I sold my Hornadys and ordered another Blaser for .375 calibre. Blaser wanted to know the diameter and height of the gas check shank. This one arrived much quicker. With some 13 thou flashing donated by a chum, it turned out some checks which fit very nicely. The OD of the check was about .384 " and running it through a .379 sizer seated it snugly. The lads at the LGS for our Friday night coffee and lies session were slightly impressed with them.
So at $140 shipped, it's not cheap, but a well made tool that makes something I can't buy. You need to screw any old die into the top of your press so this tool has something to bear against. I put a strip of duct tape around the side of my press to catch them as they pop out of the tool. Well, most of them.
