It seems the sum of the discussions centers around the one man, one gun theory, whatever the power factor. Personally, I have shot long range with many types of guns and it always gets down to your personal experience and ability with whatever the gun. One of the nicest aids I have found is on the Hawke Scope website and that's the Chair Gun Pro free download for pellet shooting where you can punch in the various data for a pellet and printout some sheets to assist in calculating the various conditions you might find on the range. It's not a given, but coupled with experience, it provides a nice leg up on calculating shot placement along with a laser rangefinder (http://www.chairgun.com/download.php). Their Ballistic Reticle Software isn't bad either (http://www.hawkeoptics.com/us/). I give a higher value to the mid and target area winds, more so than the wind at the firing point. I tend to think that the initial muzzle velocity overcomes the firing point wind to the point it doesn't have a serious effect on the pellet's trajectory. Of course, it's all relative. If I have an extremely heavy firing point wind then all bets are off and I include that wind in the calculation. Again, it's based on my personal ability and the particular gun. I don't think you can ever say that one person is more right than another in their approach to a shooting situation. It's still interesting to hear all the approaches because it may help me in tuning my shooting abilities. Tks to all for the tips.
