My Dad hunted deer with a 8mm Mauser that he brought back from WW2.
It was kinda overkill , but he never had to shoot one twice.
Two of my FAVORITE firearms are an English P14 from WWI, in .303 British & the 98 Mauser from the same era in 8x57mm.
Either is sufficient medicine for Western hemisphere game, with the exception of the BIGGEST bears.
