Yep, either average your air pressure for your usual hunting areas, a different label for specific conditions or have MOA printed on the label also so that you can input data into a ballistics programme and dial accordingly.
How about some tapered turrets???? No problem, once I sorted the maths.

Awesome work, can't wait to play with them :thumbsup:
The straight set will go on the smallbore rifle and these on the fullbore.
Spot on Matt. Ive spend time sorting what air pressure i should out for my own label. Ive also added MOA to it so i can run from a ballistics app if i need to at some stageQuote:

Looks good.Quote:

Just pre-calculate the DEVIATION from your BDC.
Then you can look at the weather and say "ok, today I dial range + 2 clicks..." and you'll be spot on and much faster than a ballistic program
Here's how to setup your BDC to work inside your weather range.

I made one with the right size socket that fitted over my turret and label maker sticker
worked for the time i needed it to
Nice! It was a real bastard working this out for my HD5:Quote:

Who said maths wasn't going to be helpful in real life?
Mmmmm pie... Coulnt resist
I "simply" made a model in 3d and unwrapped it as a 2d surface. Maths would be probably be simpler, but modeling is fast for me.Quote:

OK, I'm not going to add tapered turrent to my app...uplandstalker wins!
I brought mine in the US while there for work. Worked out about NZ $420 at the time. About doible that here.Quote:
