SIG/Sauer's newest Sierra 6 BDX (Ballistic Data eXchange rifle scopes can give us accurate lighted elevation dots (145 dots!). And 47 horizontal windage dots on the horizontal reticle, but not inside the "Xmas tree". All this can come from Bluetooth enabled monocular or binocular rangefinders and a Kestrel 5700. Your exact rifle/cartridge data are input into the scope via bluetooth from your SIG smartphone app.
PLUS SIG's "Level Plex" lighted level indicators at each end of the horizontal crosshair are extremely helpful and far better than a bubble level.
This amount of nearly instant firing solutions is even better than the current Burris Eliminator III rifle scope, and with far more exactitude since a lot of ballistic data can be crunched by the scope/rangefinder/Kestrel interface.
Many of us who are aware of the Sierra 6 BDX capabilities may wonder, how long will it be before other major - and much older - scope brands will have scopes that can do this?
Yeah, my current hunting setup on a 6.5 PRC Browning X-Bolt Pro using my Bushnell SRC 1 Mile rangefinder 10 x 42 binoculars can give me a "ballpark" hold over and my Bushnell Elite LRTS 4.5 - 18 x 44 scope with its FFP G3 mil reticle is fine, especially if illuminated while aiming at game in shadows or very overcast days. But it relies on a VERY limited ballistic "library" in the binoculars for a hold that is better than guesstimation but not great so I trued it at my range and the holds are in a Vortex scope cap liner. And I have to hope my wind guess is good too. As for level? I have a bubble in the top rear ring of my Talley scope rings.
I'd like to change over to the BDX system but with a scope with better glass than the Sierra 6 series. Then I could use my Kestrel 5700 with that setup if there was time.
