i keep hearing about light arrows not being right for big game (at other places ) . just had a customer call that went grizzly hunting . he was a heavy arrow person . not any more . hes shooting a 70 lb gereral with maxima 350s and 100 grain montecs . his arrow is 378 grains . after loosing two griz over the years he finally scored . took a 7 foot bear with a plus 20 inch skull . the bear charged him at 50 yards and pulled up at 30 he took a head on shot hittting the bear at the base of the neck . the arrow went the whole lenght of the bear sticking 18 inches out his butt . whats your thought on arrow weight for big game .
