Hornady releases 4 DOF ballistic calculator

Beyond my knowledge. but here it is for smarter people.
-
Just put in my load and compared it to AB mobile on droid, it does give slightly different results.
It also shows you stability which is neat.
they also have very limited bullets from competitors, very very limited.
-
They don't even have Amaxes listed.
-
At 600 yards it is the same results for me as AB and real life. It might work fine...thing is my kestrel automatically plugs in everything except for the distance which makes it much easier to use.

That's one thing I was kinda stumped by. They want real world data input "like that you get from a Krystel" as they said. If you have a Krystel why would you want to use their system.

@norcal_in_az not all kestrel have ballistic software in them. Mine doesn't I didn't see the point of the extra cost when I can just bluetooth it to my phone and use an app.
-
The AB part of the Kestrel is one of the best features in my opinion. I don't have to plug in humidity, temp, bar pressure, etc because it already knows those values. I don't have to plug in details about the gun either because it will save several rifles under different profiles (or barrels for DT). I just tell it what gun (barrel) I am shooting and distance to target.

So I don't know if anyone else besides Greg and myself have been following this on the Hide.
But it sounds like Hornady might be doing some big things.
What they're finding with doppler is extremely interesting.
And they claim to have gotten rid of one of my pet peeve, trueing muzzle velocity, to get the calculator to work correctly.
I understand this when you have a lower quality chronograph, but with the stuff we have today (Magneto Speed and Lab Radar) this shouldn't be needed, but it still was. I always had the inkling this would induce error, but have never been able to confirm.
Also an intersection thing I asked Frank about today, Hornady seems to want both station pressure and altitude.
I haven't figured out how to get my kestrel to show both, but it won't be hard to get the right altitude thanks to the GPS we use on our equipment which is sub inch accurate.
Just an update.
Also Hornady has released a couple videos recently going in depth over their inputs.
PS, thank you whoever designed this forum I thought I lost this entire post because I somehow closed my browser and pulled it back up and it saved everything except 1 youtube link.

What GPS are you using? Most civilian GPS systems I've worked with claim something like a horizontal error of 4 meters, and a vertical error worse than that.
Even the hand held military ones would only give you a circular error probable of something like 15 feet.
But I suppose 15 feet doesn't matter a whole lot to a 500lb GBU-38

I did some research and asking about before a purchased AB and for the most part (mainly those who know what to input where) it seems to be quite successful and accurate. Some folk taken it to 2k and it's spot on. I have no reason not to trust it. Now Hornady comes along and innovation is always good. But they are trying to compete with I think 30'ish tested bullets where applied Ballistics have hundreds. At this point I see no reason to change.
-
I don't think they are "trying to compete." I think they are trying to innovate.
Firing solution prediction has been one of the least trustworthy aspects of my shooting career. Any company that wants to further the technology has my support. Also, I think it is very important that a single company (Applied Ballistics) is not allowed to monopolize that industry simply because they are better at marketing.
Let us not forget that the applied ballistics app for iphone has been riddled with bugs and failures since it's launch. The kestrel with AB has been working very well for people, though the interface is extremely clunky.
The fact remains that G1 BC's left a lot to be desired. We moved to velocity banded G1. That still wasn't getting everything we needed. Then we moved to G7. While this can and does often work, the more distance you stretch out, the more it doesn't work. Doppler curves are the next step, and will replace BC all together.
Also let us not forget that there is a cacophony of useless ballistic apps out there that are no more accurate than a generic drop chart. More companies like Hornady jumping into the fray is sure to provide plenty of good options for shooters. The competitive juices will get flowing, whether that is Hornady's intention or not. If I were a betting man, I'd count on seeing a hornady smart phone app, and/or possibly a stand alone device. I'd also expect to see more stand alone devices from other companies in the near future. The next year to two stands to be pretty exciting for all of us.

@ragnarnar John Deere RTK, really any of the AG systems (John Deere, Trimble, I forget the third) can be accurate down to an sub inch horizontal and a sub half a foot verticle.
Farmers really want that.

My father in law runs gps on his equipment. It will drive for him except for the turn around at the end of the row. Some rows are over a mile long too. It is flat in Mississippi.

@dddoo7 if he's running deere equipment you can but a program from deere to have it turn around as well haha.
