Distance added by height of target

[shambozzie]

Are you using 1/2" kill zone setting in your calculations? Hope you figure it out.

I think you’re making this harder than you need to. To begin, if it were me, pick a pellet and use only that pellet in that weight. Set up targets at chest height every 10 yards from your probable shortest range to longest. Shooting from a rest, zero your rifle at the middle range. Once that’s done shoot groups of three at each target. Make sure your pressure stays within a very limited but consistent pressure range and don’t change ANYTHING else. See where each group is going elevation-wise. Write everything down. If there is much wind come back another day. Now for the ‘interesting’ part. It sounds like you know your distance fairly close. Put four targets close to those distances. Groups of three not changing any adjustments. New targets up another 5 feet. Shoot again, up another 5 and shoot again. See which way your groups change at each height and write it down. Of course you’ve been keeping pressure consistent. When you’ve done all that go home and have a cool adult beverage. Wait until tomorrow and go to the actual target areas. Put up targets at whatever height and find your shooting point at the probable distance. Groups of three again. Now’s the time to make any elevation changes until you are on target. Shoot freehand, not on a rest. Write down where each round is hitting. Now you know what elevation changes you need from place to place. You can do all the math but until you actually shoot, you won’t know how close your gun is to where the math says it should be. BUT WAIT, there’s more. Try three or four different pellets with different weights. You may find one your gun likes best. Use that and go to work. Also, if you aren’t using a pcp, forget everything I said about consistent air pressure , it wouldn’t apply to a pumper or springer and so on. After you go through all this ask yourself if you still want to participate in this insanity. If so, seek counseling. Yeah I know, I’m being a smart a$$ but all this really will get you started. You can adjust to suit your needs. Have fun!,
