Don't get wrapped around the axle about some one posting baloney on the internet.
The woods are full of folks who want to rain on your parade.
I have seen some amazing shots with handguns and rifles.
There is plenty of documented evidence about people like Ed McGivern and Elmer Keith to satisfy almost anyone.
When you post a target and your distance, that is what it is for me.
I frequently shoot with a very good friend who will pop the 300 yard popper with either a 1911 or my model 29.
He won't hit it every time but he does hit it enough for me to know it can be done.
