I've always been interested in the .375 on the .444 case- Ken Waters built one up many years ago, around the same time I turned the belts off some .350 Rem Mag and opened them to .375. Ken called his the .375 Express.
: Either aciton would be just fine depending on where on kept his pressures.
: With the .45 calibres, by the time you're up to around 43,000PSI, the recoil or case capacity usually stops any further progression. It is impossible to get enough 3031 or 4895 into a .45/70 case to be too heavily loaded for the #3, let alone a 4.
: A very nice feature of these actions, is they are about the fastest bolt guns to operate, and the extractor will handle about any case from the .223 to the .45/70.
: The magazine boxes can have metal or delrin/nylon liners glued, screwed or soldered in, then the lips bent to hold and feed a wide range of rounds.
; Anyone know offhand where I might pick up a couple magazines - #3 and #4?
