I live in SEMO and killed a 8 point buck at 625 yards off of my deck near my 600 yard target with a 7 wsm. I had been target shooting during deer season and the buck came up to my target. I had a bench and rest, so it was automatic. The Berger 168 or 180 hunting VLD's make it easy. Without the above, I would agree that a 600 yard shot should not be attempted
