I believe that's called 5.7x28...
Burn out barrels with unprecedented speed
Now I find that this looks like what they are calling the 6mm ARC.
Ream the cylinder to a .357 magnum cartridge diameter. I took 357 brass and necked it down. The end result was a 7.62 x 25 round on steroids and a rimmed cartridge. Had a draftsman friend make up the actual drawings but never to the idea to fruition. I was a fan of the 45-38 Clerke which has several other names. Still have a set of RCBS dies for that one. Pretty cool round but after about 3 loadings you had split case necks.
Separate names with a comma.
