If your dad shot a bear at 730 yards without any practice, it wasn't a "natural" shot, it was LUCK.
Remember, he called the shot---behind the ear!
The luck of this happening would be very close to the luck of winning the 6/49 lottery.
I grew up in the age of families living year 'round on wild meat, and shooting and hunting was of course, a very common subject, with a great hunter being revered. By the time I was a teen ager I had heard more hunting and shooting stories than most people have heard in a lifetime. I also got very adept at judging the stories and ranking them into the classes I would place them into.
20% were true.
60% were stretched, a little or a lot.
The remaining 20% were unadulterated straight, dreamt up BS.
I remember one hunter telling of shooting an elk, with his trusty 30-30. He was talking to two other hunters and he said, "That elk was 900 yards away and I got him with one shot." One of the listening hunters who was knowledgeable about shooting, said to the fellow, "Was the elk running?" "No, it was just walking!"
Now, with the story we've just read on here, I am in a quandary. I have to decide if this story, or the story I heard as a youth, gets top ranking in that final 20% of shooting stories!
