I load 41 mag with Win 296 powder, and my question arises from data regarding that combo; but it's really a more general question:
What factor or factors lead manufacturers to publish 'max' recommended loads that are well below SAAMI standards for peak pressure?
E.g., Winchester publishes a 'max' load for the 41 mag of 20.4 grains of 296 (w/210 JSP); but they indicate that this only generates 24,000 C.U.P.. The load just above this on their data sheet, a max load for 231, generates 38,000 C.U.P.--a huge difference in pressure! Other published guides list loads for 296 with this same bullet style as high as 22.9 grains. So why would Winchester publish a load so far below maximum pressure as their recommended 'max'?
I'm hoping to get at an answer beyond 'lawyers', here; if it was simply a concern about liability, wouldn't they back ALL their recommended loads down to similar pressure levels? Here's hoping one of you smart guys or gals will know what's behind this strange behavior, and thanks for trying
