lots of history with 45-70's in the north country....https://www.rifleshootermag.com/editorial/ammunition_rs_wildcat_country_051910wo/84121#:~:text=Without%20question%20the%20most%20famous%20lever%20action%20wildcat,get%20a%20400-grain%20bullet%20up%20to%202200%20fps.
the johnson 450 alaskan took advantage of the large number of model 1886 winchesters that wound up in alaska, and anticipated the model 71. i once handled one in the old gunshop on the main drag in durango, colorado - probably 45+ years ago...had the case forming and loading dies with it. i have owned and loaded a couple of hot rod 45-70's - and they will deliver the goods at short ranges....
best regards,
tom
