Gents:
I'd like to point out that 22 years before Lott's round, James Watts blew out the .375 H&H for his .450 Watts Magnum. That was 1949. Over two decades later Lott used Watts' round and called it his .458 Lott. Being a well known PH and writer he got the credit but 22 years prior James Watts was the true originator. My book on Jim has sold out of its 1200 copies but I will be pleased to forward a photocopy of the chapter on cartridge development to one of you gents to post it here.
