Re: What\'s the minimum caliber for Caribou or Elk?
I've taken a few of your northern Canada Boo's with my 270. If you reload and chrono your loads. The 140 grain Barnes BT's are deadly when launched @3200 fps.
.270 Ackley improved 29 inch 1.250 dia. target barrel 7mm STW 28 inch 1.250 target barrel. I also love my .458 mag for varmints and the biggest game in the world.
