Are all the case "blanks" for a given family the same. For example arethe 308 , 7-8mm mauser, 06' drawn as the "basic" case before getting their heads and necks . What about straight wall cases 38,357,357 maxor 45,454,460 ?
I read some where that this is done for some of the straight and tapered40 and 45 Black powder cartriges ie 45-120 is like a basic case for the 45-110,90,70 etc .
I would think so. Of course, the makeup of the various brass alloys used by different manufacturers variessignificantly sometimes. For example, not only does case capacity fora given cartridge vary from maker to maker, some makes of brass are much tougher than others.
As a matter of fact,it would not surprise me to learn that some cartridge makers buy their blanks already stamped from some company that makes tons of nothing but brass blanks. But I am not sure about this.....
(For S&W products, anyway, the thing that sets a magnum apart from a standard round, ie., .357 vs .38 Special, is that the .357 Magnum revolver has acylinder made from a stronger steel-different alloy,different heat-treatment.
