You are right Mainehunt. A heart shot deer almost always runs flat out for up to 100 yards before expiring. I wont even try a heart shot. I really like to hit the front shoulder very high between the upper shoulder blade and the spine. Thet hit the ground like a sack of rosks and very little meat damage. If I am close enogh I will take a head shot. I must qualify this position I hunt 99 percent Mule deer. I hunt 90 percent from ambush points and have plenty of time to pick a target and get into a solid shooting position. I almost never shoot at a running deer. Where I hunt if one oportunity is missed there will be plenty more. I don' t trophy hunt and you couldn' t even give me one of those stinking rutting bucks. I can,t chew the horns and they don' t make good soup. I have plenty of horns that I have found to use for knife handles and stuff. I may shoot a young looking buck if the rut is not in full swing but 99.9 percent of the time I will shoot a doe. They are thick as flys in our area and the land owners will almost beg you to come and hunt. That amount of deer can cause landowners a lot of hay loss and damage to the Stacks and stuff. They will get up on the top of the stacks and tromp around and pea in the hay to the point that thier cattle dont even want to eat it. I have a couple standing invitatios to reduce doe and for the Muzzle loader season next month.
