It’s a real cartridge, although the inventors call it the 30 SFG. Putting their last names together, you can see why they went to the shorter name.
I think it will be in the next JOURNAL but here’s a photo. As a bonus, it also shows the steps in forming.
It’s a Benchrest cartridge made from 35 Remington brass. Shortened, necked down, reduced body taper, and a sharper shoulder. The boys used 35 Rem brass because it gave them the case capacity they were after (45 grains) without a lot of case trimming. Why they used the nickeled brass, I have no idea. Maybe it was better quality, or maybe it just looked pretty.
Since they are the only 3 shooters that use the cartridge I don’t know why you’d be interested in cataloging it, but they would probably be flattered that you want to.
I know that Chris (and others) think that I make up some of these Benchrest cartridges, but there are so many hard-to-believe ones that I don’t have to lie because I can tell the truth and you will think that I am lying.
