Drew,

Thank you – all very interesting.

Also interesting (to me, anyway) that all this pretty much predates the formalization of communication between the separate arms and separate ammunition manufactures in the 1920s by the founding of C.I.P. and SAMMI.

I wonder what role, if any, was played by the transition from black powder to nitro propellants in the fading away of load recommendations. I’m smelling a significant connection here.

Best,

Kyrie
