A couple of decades back, I tried making my own gas checks. It was workable, but leisure time was at a premium so I just went ahead and used store bought checks, two or three thousand at a time. However, I have a nice NOE mould 314299 for the .303B that casts nice bullets, but the gas check shank is too large and won't accept a commercial check without a good deal of aggravation.
Someone on here mentioned a check maker maker, BFB Machine Works, so I asked him {BFB} if he could make me one which made a check to fit my bullet. He said he could and he did. It's a real work of art and it came with instructions, some spare set screws, Allen wrench, several checks made with it and a couple of practice strips of two different thicknesses, so I could find which worked better for me. A complete package. I showed it to my chums at the local Wednesday morning gathering of ne'er-do-well gunthugs and they were all quite impressed with it, for the modest price of $98 delivered.
So I then ordered a maker for my Lee .22 cal. mould, which won't take Hornady checks, and Blair came through again.
A real class act.
