I looked at the 1000 Tags Filled booklet and made a few quick notes only related to muzzleloader shots since they are most directly related to this discussion. There are 36 muzzleloader animals recorded. That sample is more than 1/2 of the data collected in this posts survey and these are from different people, so the correlations and conclusions can apply to us as a collective group. There were 19 shots into or behind the shoulder that hit lungs; 11 heart shots; 1 neck shot and 5 other. I don't know the best way to break down the data for simplicity but I will give ratios and averages to show what it says.
Dropped at the Shot - Traveled ZERO yards after shot = Shoulder/Lung 8:19 Heart 2:11 Other 3:5.
Traveled 20 yards = 1:19 Shoulder/Lung 1:11 Heart Traveled 25 yards = 1:19 Shoulder/Lung 1:11 Heart Traveled 40 yards 1:19 Shoulder/Lung (none other reported) Traveled 50 yards = 2:19 Shoulder/Lung 3:11 Heart 1:1 Neck. Traveled 90 yards 2:19 Shoulder/Lungs (none other reported). Traveled 100 yards 4:19 Shoulder/Lung 3:11 Heart 1:5 Other Traveled 220 yards 1:11 Heart (no other reported).
If you just take an average: Shoulder/Lung shots = 40.26 yards; Heart = 65 yards; Neck = 50 yards and Other = 34 yards.
There are some obvious conclusions: A shot that damages lungs results in the animal succumbing in approximately 1/3 less distance that one shot through the heart. The one neck shot represented likely did NOT hit the spine and the Other shots vary widely to include spine, liver and gut shots which may explain why 3 are DRT, 1 traveled 70 yards and 1 traveled 100 yards. Another noteworthy tidbit is that 1:36 animals went more than 100 yards. 25% went 100 yards and the remaining 75% went less than that. 34% were DRT. The Shoulder/Lung shot produced more DRT's, nearly 50% and also resulted in the least distance traveled after the shot. The Heart shot produced around 20% DRT and the longest distance traveled after the shot (compared to the other shot placements recorded).
The other important notation is that the animals represented are not just deer. There are only 5 Whitetail Deer represented here. There are also 3 Black Bears. The rest are Elk, Hippo, Water Buffalo, Watusi, Red Stag and Cape Buffalo. There are also 45, 50, 54 and 58 caliber muzzleloaders represented including conicals and ball.
There is a ton more data such as how far the animal was from the shooter, projectile type and weight and more. I'm just providing a snapshot. Again if the OP wants to go through this I can send it to him but it is over 200 pages of data to sort through.....
My personal take-away is that a muzzleloader is a formidable tool for any hunting!
