Last year my brother in law had a huge buck run under his stand in heavy timber near a field edge, he shot four times, when the buck hit the field edge he hesitated for a moment and his last shot did the trick ! I have jumped many bucks in timber when caring a bolt rifle and never had a chance, just watched them bound through the timber.
I have to say two things in respose to this post.The first being that if it takes a person four shots to get his animal he needs more shooting practise not faster follow up shots.Unlucky events can occur to any of us that could cause a missed first shot but missing three shots is not bad luck it is simply poor shooting.If you jumped bucks in the timber but had no chance for a shot a faster follow up shot is not a factor.If you have missed many shots then shooting practise is again in order.
I am not saying that I don't miss shots myself because I have missed my share over the last 30 some years.When I did miss I checked over my rifle ,accepted the fact that I screwed up and put in some more practise time.When it comes to shooting accuracy quantity will never replace quality..
