Your right BigUglyMan, the problem with hot weather is all about powder.at the time when this cartridge came out (early 1900's). Cordite is old news and we are living "IN THE NOW". Gunslinger should know that the .416 rigby can be handloaded to kick the .416 rem.'s ass. Roy Weatherby put a belt on that sucker and showed them how it's done.
