Leupold BX6 Range HD

[Pronghunter]

So this new BX6 is gonna replace every RF Bino out there? Better glass than any other out there including German glass? Better RF?
Who has had their hands on them behind the scenes? I know there are a few Leupold pad guys on here. Give us the deets. Insanely bold statement, especially on the glass.

They dropped the ball with no applied ballistics

According to Tract and Leupold, their solvers are more accurate than AB….

$1000 more than the leica seems agressive. I don’t mind 4dof though

4dof legitimately is so bad though. The glass would have to make Swarovski look like the bottom of a coffee pot to make me even think about it.

What makes 4dof so bad? Genuinely curious. I have had excellent results to 1000 and beyond on most rifles/loads. I have had a few odd balls where elevations didn’t land where I thought they should, but very few. I use it and ab quantum and very rarely get a different solution.

When I've used it and compared it to my Kestrel w/AB I've gotten numbers that would've caused misses at extended ranges. Maybe I'm not feeding it enough information but the Kestrel has always been spot on, even if I don't true anything; I just use the AB Custom Curve and run with it, out beyond 1k yards. Since I've gotten different numbers from 4DOF, and I've grown to trust AB, I cant trust 4DOF.

Do you dislike 4dof from a user interface/usability standpoint or from an accurate ballistics data standpoint?

Both. The user interface is about bad as any app on the market- I saw the proto version when they were working on it and told them so. It’s awful.
But it also produces bad data. It does ok with Hornady bullets, but way over estimates aerodynamic jump for instance for any bullets that aren’t theirs.

At the start- it does nothing for the shooter that a decent calculator doesn’t do.

have seen it be more accurate from the start and require less truing...

I have used them in person in the field and they are every bit as good as EL Ranges, optically. Also a better ballistic solver than EL Ranges as well with 4DOF. Only directly comparing to EL's, since they're the only other range finding bino I have experience with.
Heard they also use Precision Cut Archery for archery ballistic calculator. They are pricey, but with repairs/warranty claims being made in Oregon rather than the other side of the pond, they do offer an advantage there over competition as well.

4dof works in most scenarios, I ran a 4dof kestrel VS AB Kestrel at a handful of prs matches , comparing solutions, and they were within less than 0.1 mils of elevation and wind.

You have to get the 4dof system trued! Standard profiles don't always match up well, you have to shoot at distance and tweak form factor to make the solution match your inputs for it to all line up perfect all the time.

Applied Ballistics, man it's usually load up the custom curve for your bullet, make sure all the inputs are correct, and you have good enough solutions to put you on 2moa sized targets to 1k yards. Minor tweaks to BC are needed here and there, but not often.

Then there is high angle shots, 4dof is no good in this realm. This is where 4dof fails. Even with inputs total dialed, and trued in both, 4dof will spit out grossly miscalculated solutions.
