Yes, in the 9x23-38 Super it is a brass limitation. 9x23 Winchester brass uses the design of the 1911 to its limit. The weak link then becomes the primer cup.My question to the gunsmiths of the world -- is the brass really limiting the pressure limits ( of a 1911 I presume)
The dbl blend process which Ricco owned and patented is what allowed the unsupported barrel. The courts already decided that infringed on Riccos patent and Winchester paid the damages to Ricco.Am I wrong to add that Ricco's CP case was a straight wall opposed to Winchester's slight tapered 9x23. This design would eliminated the need for supported barrels and perhaps enough of a change not to infringe on John's patent.
