I'm not sure how far out the ballistics with a 1911 will reach...
I hit a 12-in square or so little old TV at 100 yards once. One day I was out shooting with my Marine corps brother and he got upset. Here I am shooting rounds across the canyon at the embankment on the other side of the canyon. He totally thought I was just randomly blasting.
About 300 yards off and I had asked him exactly how far is that one rock over there just above where my rounds were impacting. It was pretty big rock. My brother laughed and said there's no way you can hit that it's dang near exact 300 yards out.
Now I have to say this Marine corps veteran has an extremely specific set of skills and one of them happens to know exactly by eyeball within about 5 yards exactly what any range is visually. Even with binoculars. It's pretty crazy skill.
