We have three farms that we hunt on. Two of them have steel plates for targets. One is setup for 1000 yds. The other has a 500 yard plate and a 800 yard plate. We have target stands for paper from 100 to 800 in 100 yard intervals. At the third we watch deer from 1500 yards, get an idea where they're going and get set up for a 200-300 shot. We shoot off bench and off bipod(ground). Yes, I can hit out to 1000 yds off of a bipod. Hunting is a different story. Ethics come in to play, but I have and will drop the hammer on a deer at 500 yds. You said you were not apt to be faced with a shot like that. Wrong. I did not comment on the 223 or its ability to kill at those ranges. I agree that 300 yards would be the limit. If you stepped up to a 22-250 or used a 243-6mm, I would go to 500. I use a 6.5 WSM for all my long range shooting. There are a hell of a lot of cattle pasters around here. 300 yds across is an itty bitty one.
