I have been going through some older American Riflemam magnizines and found an article by Col. Charles Askins entilited “.375 H&H: Patriarch of the Magnum Clan”. In the article he says “Virtually all our beloved magnum loadings claim a single ancestry (the .375 H&H Magnum). In 1911 some brilliant but unknown engineer at Holland & Holland designed it … Unfortunately, this genus is lost to posterity. We’d like to ask him why he settled on the .37 cal., why he put the novel belt on a sporting cartridge and why did he make it a rimless casing?”
With all the research done in the 20+ years since Col. Askins asked those questions, can we answer any of them today?
