6mm Themos bottle and SMc style cartridges ?

anyone ever shot one of these cartridges that Mcpherson designed ? Find their reasoning for the design interesting (and pictures for slow people like me ! )

Im looking into these now.... :o

Seem interesting so does this round 5.7x28mm

I have shot a 5x35 for years it is a good cartridge it is slightly faster than a 204 I get 4000 fps out of a 39 siera you need to use br primers
