RE: .410 on deer?
I don't know anyone that has killed a deer with a 410 that neaded that many shots. Most were single shot H&Rs or something like that. There is no reason why if you can kill one with an arrow you can't kill one with a 410 if you limit your range accordingly.
I understand that an arrow works under a different principle as a bullet does, but any projectile thru the lungs is going to kill a deer. You just may have to track it some. Now if you think you are going to drop a 150 lb deer at 100 yards in it's tracks with a 410 you have another thing coming. That third, fourth and fifth shot are not going to anything the first one didn't if it went in the right place.
Believe me, every season I see quite a few people that fire 4 or 5 shots with a 12 guage to bring a deer down. If you have that mind set it really doesn't matter what caliber weapon you are using. I can see a lot of hunters from my blind. I hear a lot of shooting, yet never see any of them drag a deer any where? Yet I manage to kill one every year with a single shot from a muzzle loader.
If you have to take more than one shot it was not because of what you were using, it is because you missed or used the weapon beyond it's capable limits. Both being the hunters fault, not the choice in weapon.
