While I'm waiting around for next fall I've been researching Western hunts that I can do a bit later in the season. One that jumps out is Coues Deer.
According to Chuck Hawke https://www.chuckhawks.com/coues_deer_cartridges.htm, "Bucks average about 80-90 pounds and does are smaller, probably more like 65 pounds."
He recommends mostly 6-7mm stuff, with 7.62 in non-magnum at the upper end.
Would I be destroying too much meat taking one with a 450bm? I see Black Butterfly load a smaller, faster 160gr bullet that moves at 2775 fps. The extra speed would give a longer, flatter trajectory for western stuff. But inside of 200 yards would a .45 cal bullet moving that fast destroy too much meat?
