Ok, I admit to having too much time on my hands to calculate this but all the comments about bang/flop got me thinking.
Usually that isn't a good thing, but it was fun anyway so here goes.
I have only been deer hunting for about 18 years and average just under one deer per year so my ratios are easy to calculate. I came up with 4 ratios. The overall bang/flop ratio which counts all deer no matter how they were hit. The ideal hit ratio is where the shot was heart/lung/should shots which should be the quickest, most effective shot. Of the deer I shot, I also calculated the percentage that ran out of sight for both ideal shots and overall. So here are my numbers:
Overall bang/flop ratio: 64%
Ideal hit bang/flop ratio: 78%
Overall drop in sight ratio: 93%
Ideal hit drop in sight ratio: 100%
All of these deer are with a 30-06. I am really pleased with the drop in sight ratio. Out of the deer I have shot, only 1 has ever run out of sight and he was shot in a quartering frontal shot. All the rest have dropped in their tracks or have not gone out of sight.
So what is your experience?
