That's an emulator, I don't actually have a Playbook at hand. Some of the screens will be underpopulated, since it is really a phone app.


edit: A day late and a dollar short:

I submitted it as a freebie to the Blackberry App store. "Playbook Ballistics" is the name, it will take a day or 2 before it arrives. They really want control of the distribution.

It has to go through the store, they have it so I can't sensibly give it to people.

It has geolocation, coriolis and so on, I would appreciate it if somebody would let me know if it works on a real Playbook, thanks!

I went looking for it, doesn't show up in App world, sorry. - dan

Are you trying to tell us that your brain can hold more information than the computer and recall any of that information at a moments notice regardless of distance or any variable that will affect that bullets trajectory?

Im saying that with my .308 i can hit a target cold bore being first or second shot out to the weapons effective range in varied conditions, without the use of a handheld ballistics computer. Dont try and make long range shooting more complicated then it really is. Even a cat’s brain smokes the newest iPad 1,000 times more data storage and a million times quicker to act on it.

I just memorize one set of ballistics charts for a certain altitude, tempurature, barometric pressure, humidty and all the others factors and when those change i adjust for it by relying on the experience i have shooting all my life and long range shooting for a large portion of that.
 
I am going to pick up SHOOTER ballistic program. It's only $10 and if you have a built in gps device you can even take advantage of the coriolis plug in. It also has a spin drift calculator in the mix.

One question, one comment:

Question- What is your .308's effective range?

Comment- "cold bore" means first shot. If you're taking a corrected 2nd shot, that means your cold bore shot was a sighter

Answer: Us army says 800 meters USMC says 1000 yards, For me ill say im confident enough to take a cold bore shot at 1000 meters, if not 1 shot ill get it on the second. As for Cold bore ive heard an AMU guy say it was 3 shots then ive heard the number of shots until the bore heats up and ive also heard the one shot, then there is Clean Cold Bore and Cold shooter, But your right cold bore is the first shot.

Thanks for the reply.

The reason I ask the question, is that "effective range" depends on the target that you're shooting at, and your intended result after hitting the target. ;) The USMC is obviously saying that 1000 yards is the max effective range on human targets. If you're shooting at a steel plate or a coyote, or something, the effective range of the .308 is well beyond 1000 yards, and I've seen guys successfully use that cartridge on targets out to beyond a mile. So it's all subjective to your perspective :)

You guys see Tigrr's thread about shooting 308s to 1760 yards?

In the precision/long range competition section.

Yes sir. I'm man enough to say I'm green with envy. Looks like they had an awesome shoot.

Back to the op, I use iSnipe on iPhone. I have BulletFlight as well but prefer iSnipe.
 
k so I "trued up" Isnipe

I know my speed is really 2980 but 3260 is what I used to get my dialed dope at 500meters will run this speed to see how it does out more
 
I have been Having problems with Shooter.
For example I shoot out to 600 meters shooters says up 18.9 MOA.
To accually hit I have to use 23 MOA.
I go into the chart and do a velocity calibration of 600 meters for 4.1 MOA and calculate it and all the velocitie says MV 4610 fps and my dope will be Up 3 MOA at 600.
or if I type in the accual range and 23 MOA for correction then things get even worse.

I am doing something wrong? This program seems good but is just not working.

I have messed with this program for hours and used chrony's to check real world velocities and it won't work for me.

Any help would be appreciated.
 
B.C. Values are correct, straight form Sierra 168gr Match Kings. I chronyed first thing in the morning then a few hours later because of the uncertainties. I even ran the program on the ipod to see it it was the phone itself.
The atmospherics are the only thing I can think of but I have checked over and over and got buddies to do the same.
Frustrating...

I just won a Blackberry PLaybook. ANyone know if the android stuff is working ok on OS2? If so, anyone tried JBM or Bulletflight on a Blackberry product?

Might return it for an iphone simply for the ballistics programs offered for iphone vs playbook. Not to mention, an iphone can be used anywhere to get the information where the playbook has to be in wifi range.

Use your non BB phone to create a wifi hotspot and use your PlayBook anywhere.

Thanks for creating this app. I'll try it out and let you know how it works.

Your chrony is probably only accurate to +-5% which means that your reading could be off by 200fps if your shooting at ? 22-250 speeds. It doesn't sound like this would acount for all of your error, but it could acount for part of it.

The remaining part is most likely that your scope isn't moving exactly 1MOA when you think it is. This is more common than most people think. Set up a target at 100yd and shoot a group at the bottom of the page then dial up 10MOA and shoot another group. From center to center the two groups should be 10.4" apart. If not, you need to edit the MOA Correction Factor in your rifle profile. Luckily, Shooter has a solution for this common problem.
