I'm going to post a link below which is helpful and will be more informative than what follows.
Any of you guys using this? Apparently, this has been a thing for a couple years but I only recently became aware of it, and now there's a function in the Kestrel 5700 Elite for it. I tried it out to 525 yards the other night and it was center impacts all the way out. Haven't had the chance to validate it beyond that but will shortly. Honestly, I'm thinking it's a game changer, especially for hunting.
It only works with mils but basically, it turns your FFP reticle into an accurate BDC that is accurate to within either 0.1-0.2 mils (you get to pick the tolerance) between 2 distances. For my 6.5 Creed shooting the 130gr Sierra Gamechanger at 2670 (I was experimenting with N540…very accurate but 100fps slower than RL16), the number was 1.8 and is supposed to be accurate within 0.2 mils between 199 and 664 yards…which computes out and I believe…especially since it worked as advertised out to 525. For my 7SS w/ 190gr Berger the distances are 430-1140 yards and my 338 SS w/ 200gr Badlands is 330-949 yards. Which is potentially incredible.
The way it works is first you divide your distance by 100. So for 500 its 5.0. You then determine the difference between your yardage and your DOPE in mils. So say your DOPE for 500 is 3.0 that number is the 5.0-3.0=2.0. If you don't have a Kestrel, you'll have to manually determine at what distances this is no longer true +/- 0.1/0.2 mils. Anyhow, the process is straightforward. You can watch the video from the link or Google how to get it to it within your Kestrel (very easy). Once you determine what the number is that works, that's your Speed Drop number.
At any rate, once you have it, you zero at 100 and then dial your turret BELOW your zero whatever your Speed Drop number is. Then, based upon the distances you or your Kestrel have determined, you literally range your target, hold the range value/100 (I.e. 525 yards is 5.2mils) in your reticle, and pull the trigger. For anything closer than your predetermined distance you hold you Speed Drop number. For something like my 7SS, I may have to adjust that practice a little because the BC is so high that the linear drop portion of the bullet path starts pretty far out there. For my 6.5 and 338 it's not necessary to change that practice at all and works perfectly.
