Woaahhh way too much info!
Draw a triangle. It's the horizontal axis that is the true ballistic distance.

Interesting, I haven't seen such a big difference between up angle and down angle as in that table before. Dunno what that means, guess you'd need to check it and verify it by shooting. There was a manual device in the past called a 'Mil Dot Master' that used a string and a weight to give you the angle then that gave you a correction for range as estimated off the mildots in the scope. Surprisingly accurate to be fair, but a wee bit of fluffing about to achieve the corrections...Quote:

Mate shot a stag same trip 682yards very steep uphill shot and tbr range was spot on too.
Am I missing something ?
We dial for our shots not holdover just for clarity :thumbsup:
Some people overthink things and make mountains out of molehills. Get fecking closer, you have to recover animal anyway, or man-up and pass on the shot.Quote:

I wouldn't have thought a 300y shot was that far to consider passing up, easily ethical with most centerfire offerings for example; a 270win with standard 130gn interloks zeroed at 200y is only 6" low at 300y, a good rest and holding a little high would easily see you sorted.Quote:

Some interesting stuff here for those who like to understand how things work

You're showin your age Mick - its a lot more complicated that that these days, and thats why you need your iphone before you make the shot.Quote:

Personally for a 300y shot I probably wouldn't bother dialing just hold a little high, job done :cool:
personally for a 300 yard shot the hold a little bit high is actually ONLY a little bit lmfao.....see above chart and knock and inch off/add inch onAttachment 220321
Correct depending on your zero, 100y, 200y or whatever you choose to zero atQuote:

thus the add/deduct inch comment ...but youknew that.... actually matey..seen as though you have already done the flash harry chronicgraph thingy....just for shits n giggles can you PLEASE USE YOUR .308 LOAD DATA AND CHART and same with your dirty06ai and stick the new flash data up beside old old needs a zimmer frame data with as near of projectile weight as youve got...just so folks can see that real world difference isnt that huge
Hence my earlier comment about using tbr range finderQuote:
