This time last year I put out an appeal for some help with research into the Bang Flop phenomena.
12 months on and 5 of us have contributed to the data pool and we have good information on 141 deer shot in the chest. We are not interested in head or neck shots, we all know what happens to them already.
Because there are so many different calibre's, bullet weights, bullet constructions, terminal velocities, species etc. our data pool is still not large enough to come up with too much in the way of conclusions. We set out to get 1000 records and it looks like we will have to get that many to prove anything.
I was very fortunate that one of the SD members volunteered to help work on the data. He is a scientist, statistician and keen stalker. His analysis of the data has been very professional and he has kept me on the straight and narrow. I will not mention his name here, but he will make himself known if he wants to.
There are some patterns emerging, but the numbers we have for each calibre and bullet type are not great enough to prove anything statistically.
A couple of things we have been able to prove statistically.
The greater the awareness of the deer to imminent danger the lower the chance of a Bang Flop.
The larger the animal the lower the chance of a Bang Flop.
The faster you drive a bullet the higher the chance of a Bang Flop.
What we want to get into is the effect that calibre has, the effect that bullet weight has and the effect that bullet construction has. To get there and prove it beyond reasonable doubt we are going to need help.
This is an appeal to all you guys to help by sending us your data. I have a simple spreadsheet that we would ask you to complete with each deer shot. When you get to 10 on the sheet just send it back to me and we will add yours to the pool of data. Your chance to be part of a study that could give us all some proven answers on subjects that we all spend a lot of time discussing.
We are interested in everyones data. Everything is relevant - providing it's UK deer species shot with a legal calibre. There are so many gaps it's difficult to go through all of them, but here are a few we would like to get hold of:
Those driving .30 cal bullets over 3000 fps MV
Anyone with a 270
Anyone driving 7mm bullets slowly
Anyone using Barnes TTSX or TSX bullets
Remember, it's chest shots only.
If you can help please PM your email address to me and I will send out the form and instructions.
