A fellow here on the coast got a nice elk with a 70 lb compound bow at 10 yds,fixed broadhead .through the heart ,almost went out the otherside.But on a heart shot ....done deal .Oh ya 70 yds was as far as the old boy got. nicely done .If you don't hit the heart and don't have enough penatration to get both lungs that elk will go for miles and miles and miles...you get the picture.done it not fun.
