I have 22 'Rush' cartridge that was given to me some years ago. It is a .32 Auto necked down to .224. Same thing?
Supposedly a Jack Rush from Montana had a Cooper 22 centerfire that would not shoot to his satisfaction and got into a peeing match with Dan Cooper over it. Must have pulled the barrel and rechambered for this round.
Jack has passed away but he was a contributor to the old 'Small Caliber News'.
The cartridge was given to me by a friend in Broadus, MT.
PM or E-mail me if you need name. etc.
