Home Forums Hunting & Shooting Ask The Gunwriters Hornady new app ballistic? Any reviews

Anyone use this app?

It’s a joke. First time I wouldn’t create an account, then said it couldn’t send notifications 😂 it crashed, kicked me out.
2nd time no account created, allow notifications it let me in. Free load data, select cartridge, message”you must log in to your account to see the data”. Then create account, allow notifications, pay $1 per cartridge or $20/year subscription. Delete will be next. Don’t need another account to be marketed junk to. LMAO leave it to Hornady to screw the pooch.

any better ones out there used drop sheets for years but now have to pull out reading glasses have iPhone

Yep, spend a few bucks more and buy the book.

If you’re talking the 4dof app, it’s an extremely good ballistic app. I’m fact it’s the best I’ve used. It uses actual Doppler drop curves, essentially tracking the bullet from the muzzle to the ground. Most ballistic curves are based on BC’s derived from muzzled velocity and time of flight. By having the actual bullet tracking data, it’s much more accurate than any other predictive app I’ve used, including applied ballistics. It does take some work to adjust your axial form factor which is essentially truing the data to your rifle which can easily shoot a projectile slightly different than the test bullets used in the Doppler curves.

Overall an amazing little app, and very accurate.

I use Hornady’s 4DOF app. I don’t know what Swifty52 is talking about regarding payment, etc.

It’s an excellent app if your bullet is in the library. Getting the axial form factor set is key. You’ve got to run your loads out a ways. I tune AFF out to 1100yrds. I notice AFF change significantly after a new barrel speeds up.

^^^^^This^^^^^ is the reloading guide, not the ballistics app.

The OP is asking about the ballistics app.

This is the ballistics app...

FREE

I am a huge fan. I was also fortunate to spend a week in Africa with the individual who ran the creation of the 4DOF, over beers at night he showed me all sorts of functions (bullet stability with different twist rates, etc.) and explained why they were important. I will say that it takes a bit of practice to learn to navigate it, but once you get the hang of it, it's fantastic.

If you talk to him, please ask him to add Gain twists for me. I use the final rate, but my AFF’s seem to vary widely through break in. I went from a 1.9 on a new barrel to a .9 after 200 rounds.

Thanks John, Kingston, woodhit for your input. All I needed to get the app, just afew guys that have actually used the app. The presentation on Youtube was very well done also I might add.

I still have one on the PC called Point Blank that was a free download many years back. Just compared results with the Zeiss on-line software and they agree to one place behind the decimal out to 800 yds. If ballistic coefficients are correct, it seems the math was worked out years ag.o

I just attended a long range clinic where we used the 4DOF app. I'm shooting ELDX bullets so of course they are included in the data. Don't know what you need for other bullets but for a troglodyte like me, it was easy and very accurate. Went from never having shot any long range but High Power to ringing steel at 1000 yards with confidence on the first shot.

Right on . I also noted that they update their software to include newly marketed bullets. I have about 1000 rds 300 grain SMK 338 caliber so I need to shoot alot before I buy new better (Berger) fodder. LOL Thanks also to other posters. I'm looking foreward to trying out this new app.

I use it all the time. It's quick, accurate, and easy to set up the calculations you need. There has never been a charge. I don't use the 4DOF app.
