Watched a guy on youtube hitting 200 yard silhouettes with a colt 1911.
I say not impossible in the least bit. If it will throw the round that far, then yes, the target can be hit. The bullet will lose so much velocity that it will be pretty much worthless as far as stopping power goes (it will probably still produce a hole and an ER trip on a soft target)
All in all, it's a neat range trick, but impractical as hell. And the question is, can he do it reliably? That makes it an even neater range trick.
Bob Lunden can hit a deer silhouette with a snubbie, at some pretty outrageous ranges (can't remember the numbers, but I think it was well over 200 yards). It's not impossible, but it does get to the point where there's much more luck than skill involved.
The man who helped develop the .44 Mag, Elmer Keith, made 600 yard shots on a large antlered game animal (can't remember if it was elk, caribou, moose or whatnot.)
I always misspell Bob's name. It's Munden, not Lunden.
