Over gunned?? Please. Hard hitting, medium recoil, big leaky holes if they even move and eat to the bullet hole. You ask "why"...i say 'why not'. Its okay man. Lotsa ppl suffer from whelen envy
With tht logic 50 cal smoke poles @ 2200 are too much for white tails too.An '06 slinging 150s or a 7-08 pushing green box 140s is far more 'explosive' and creates far more blood shot meat then any whelen load all the while not having the snot to drive through a big bodied white tail north to south. Thats the beauty of the col. It just plain works and works WELL on everything from wood chucks to brown bear with loads from 150gr hollow point pistol bullets to 310 woodlieghs and everythimg in between.
