720 on a Bull elk. That was my first and longest, and I learned a lot about my equipment and set up since then. Most since then have been between 300 and 600, which I feel completely comfortable on given the right conditions. Ever since I started dabbling in some long range practical rifle competitions, my idea and concept of "effective range" has completely changed. If I detect or suspect some type of wind uncertainties, I either get closer or don't shoot. Wind is the great equalizer and can certainly be the difference between a dead critter or a wounded one. I would say I have conservatively put well over 2000 rounds down range in the last few years,have seen at least twice that, and the one thing I know for sure is that misjudging the wind or changing wind conditions will make the difference.
