I shot a doe in Pa last season just over 400yds according to my girlfriends dads GPS. She was broadside and standing still. When the bullet hit her she dropped like a ton of bricks and didnt move a hair. All the conditions were just right and I was in the prone position. No wind. There was no way we could get any closer for that shot and unless I get a perfect opportunity like that again I'll never try it again. 300 yds is my max for the most part and thats with a good rest. Offhand, no more than 150 or so. My gun of choice is a Sako 3006 shooting Hornady light magnums w/ a 150gr SST. +1.5 at 100yds, -6.5 at 300 and -20 at 400. I dont guess it hurts that I like to shoot alot either
