I said seemingly has that effect.
The question was directed at others who had heard of or seen the effect themselves.
My father for one has noted it when he went from a 117 gr spitzer boattail to a 117 gr spitzer flat base in his .25-06
I don't know how many people I've asked about it in the last 20 years or so but quite a few very expierienced hunters.
I never claimed it was scientific just an observation.
If the deer was shot at long range, say > 200yd, the boattail will contribute to a more accurately placed shot.
How exactly would a boattail accomplish that?
There may be no scientific validity to my observation but I know the science and reason behind the boatail design and thats not it.
