Ballistics app?

[jmccracken1214]

Ive been using strelok pro for a while.

I can't figure out the slope angle. On my friends iphone, he clicks it, it opens his camera.. On my android, it does not.

Are there any other apps that are better than Strelok? I put in all the weather info correctly, my bullet info correctly and 99% of my targets yesterday the dope that the app gave me was off by a little. I was almost always high. Ended up backing off 1 click from what the app said and aiming low.

Not sure why, is it something I may be doing in the app?

I’ve found that a ballistics app is a great starting point, especially considering all the factors, but your own dope is what you need when technology isn’t spot on. Get the pen and paper out!

I’m sure someone will come along and have a good recommendation or advice on the app.

The ranges they had varied greatly... Some stages would be something like 474, 951, 830.. for example. With distances like that, dont you have to somewhat depend on the app or is there a good way to get your dope for crazy distances like that without burning up a lot of ammo

The ballistic apps are similar to reloading data. Its a general reference that should get you close.......your results may vary slightly. The range card is the way to go.
Does the app not factor in angle or is it just slightly off?

I had wrote down all my adjustments for the dif. ranges with a 0 degree slope. I went back after and got a 2 degree slope on one of the targets and put that in, and it had the same adjustment as 0.

I was high on the 500 yard and closer targets, but at 1013 yards, i was sending them over the 18" target aiming center. had to aim at the bottom of it to hit high on the plate.

I do burn a lot of ammo when practicing and figuring my load. If you know your own dope at 800, and know exactly how much off it was compared to the apps at 800, it will be close to that much off to the app at 830. Im not a competition shooter, but I am a hunter and practice out to long ranges, even though I hardly ever take game that far. At least I’ll have the skill and know how to. I attempt a group every 50 past 500 to 1000. Yeah it’s a lot and takes a while, but I know what my rifle does. I’ll get a load, stock up, and stick with it, so I don’t have to burn that much ammo on a range card often.

I wonder if the ballistic coefficient or load is off compared to what’s entered? Idk, someone with more experience will be along

I'm not sure if or how much difference it would make for you but when I set up my chrono, I use the Clinometer app on my phone. I will get my rifle lined up on my sandbags, being sure the reticle is on target or at least pretty close. Then, ever so gently (being sure not to move the rifle) I rest my phone on the elevation knob on my scope. I set my chono at the same angle to keep it consistent.

It might help with the degrees of slope..... it may not.

I have used Sierra Infinity with excellent results. If you enter the correct data, it is spot on from my experience. I have used it several times while testing for clients and have never had any issues.

Lotta environmental changes going on last Saturday that made everyone’s data look off. Mirage on the 1000 yd line that wasn’t there on the closer hills. Wind does funny things there, too, with those hills and valleys. And throw in all the different ways you were having to get a cheek weld, too.

My advice: don’t sweat the minutiae. You’re trying to measure with a micrometer what you’re gonna cut with a axe. Write down your results, and adjust what you’re doing as you see trends - ie if you’re actual is .3 higher than predicted on stage one then figure that delta into your stage 2 dope. I’ve seen too many shooters “shoot high all day” because they keep doing just what their app says even when they know it’s high.

Do you know anyone with a kestrel? It's almost a must have when you get into comps. You build a profile. It tells you what your ballistics should be. Then you shoot and get actual data then change it in the profile accordingly. You can use g1 g7 or CC ballistic coefficients. I use to Use strelok and when I switched to the kestrel my hit percentage flew up.
