Nothing new. Somebody does this with some cartridge about every 15-20 yrs. Magazines had had articles, I remember from when I was a kid, (early '70s). Again in late 80s early 90s.
One tried a pistol to create a .45 ACP WC. Another loaded .38 HBWC backwards to make a HP.
Again, just because you can, doesn't mean you should.
