Yeah that was a heck of a shot, long distance handgun shooting is a lot of fun.
My range isn't that long but I shoot out to 100 yards all the time. Golf balls and paint balls make fantastic targets.
I find that a lot of people at ranges restrict their handgun shooting to silly close ranges, like 15-20 yards. Its a shame because with a full size piece you can easily engage targets at 100 yards, sometimes more.
