Don't think I can come up with enough paper to measure my bullet drop at 1000 yards and my wife gets upset when I shoot at the house. Shot out to 600 yestarday.Think if the experts that build the bullets we shoot can figure within a couple inches of what I now know, I'll put a little faith in them. Speer and Leupold sure did a nice job on by buddies rifle. Thanks again to all you guys for your help....those TSX's are the way to go!
