DoubleRifleNewbie,470 yrds is a nice shot (on anything)! Using a .338wm on Caribou is like a Bazooka on deer - anything knocks down a Caribou..according to my Guide in Quebec “they are the absolute sissy’s of the hoofed animals - the sound kills them”. At least that was true for the Leaf River & George River herds in 1999-2000. I used a .270 and felt over gunned, 2nd trip used .243 and great results (once at 400 yrds.) they all “drop” as soon as hit, Guide said their central nervous system seems very sensitive, I’ve only seen 7 killed but all dropped at the shot, not as tough as a deer - based on my limited observation. Too bad the season is closed on the Quebec herds - that was a fun hunt, high success rate and unique part to the World....the meat was also excellent and as good as any game I’ve eaten.
