I’ll play.
I shoot a good deal of jugs and steel plate at distances from 200 to 450 yards throughout the spring to early fall.
Distance on game with a particular rifle is limited to the ranges where I was 100% successful during the final weeks of practice. Meaning I hit the jug or the painted circle on the plate first time and every time.
Reality of course is more challenging than practice, so I am accepting a less than 100% chance of success, but I am shooting under conditions where I have assessed my equipment and skill sets as being up to the task.
I'd hope most guys do this or similar.
OP-
I restrict my shots to only taking those in which I fully expect a dead deer when i squeeze off. What is that?
90? 95% 100? I dont know.
Through experience at the range and in field, I've learned that for me this means taking offhand shots at moving game in timber is out. Period. I dont accept a 50-50 shot on game animals. (why I accept it on varmint is, I think, another thread).
Some seasons, with more practice, I extend my range limitation. Others, less.
I tend to hunt closer and quieter when I range restrict myself.
Disclosure, 99% of my big game hunting is with some form of Muzzleloader.
