Strelok+

[KDX]

I ponied up the cash ($6.99) for this ballistic calculator after having used the free one for a while. You can save 10 different rifles with 10 different loads for each one. I like it as I have 3 different Leupold scopes with the fine duplex and they are all available choices in the program as well as being able to have different target choices. There is a more expensive Pro version, but I did not think I needed that one. I used CCI's Mini Mag data and a 50 yard zero to set up my 10/22 for crows come spring.

List of supported reticles if anyone is interested.

I had purchased Strelok pro last year for my 900M shooting.
With data closely entered, it gets me on target up to 500M no problem.
For some reason, even with truing done and linked to my Kestrel via Bluetooth for atmospheric conditions, past 600M it has a real hard time getting me on target.
JBM ballistics on the PC is bang on so i use range cards instead of Strelok now.

But, many critters dropped thanks to Strelok.
When my buddies prepare to go varmint hunting, i usually go out with them before to zero rifles.
I chrony their ammo, and with Strelok supporting a wide range of reticles, i send them a screen shot of drops like the one you got (going up to 300-400M).

I know it’s appreciated, as when someone in the gang gets a new rifle or scope, they enjoy having this card i screenshot them after a chrono/zero session.

I have used this program for years and credit a lot of my success in long range shooting in the US to this ballistic app (since practicing at 400-600y is near impossible where I am).

Like it so much I bought the pro version for Android. When I got my iphone at work I couldn't be without it so I bought the pro version for iOS as well.

Developer is great, and very responsive to questions/requests.

Just a solid app if you ask me

I find it's pretty accurate as long as all the parameters are set properly....

Glad to hear others are liking it as well. I've rarely shot beyond 500 yards so I think I should be fine with this version. Which Kestrel do you have?

I got the Kestrel 5000 with Link
Does have density altitude, does not have wind direction.
Still, pairing with Strelok is dead easy, and your drops are kept to speed in real time as the Kestrel changes it’s readings.

Now you got me wanting to try it again.
In my data book, i have an 800M outing, which i have marked every actual meteorological conditions, actual speed of bullet through the lab radar, and actual drops all on the same day.

When this data is input in JBM on the PC, gives me the exact results as real life.
When input in Strelok, it is considerably off at 800M, off enough to hit the ground at 600M before the target.

Will try to tweak it again, and email them if i cannot get things working, to give it another chance.
As at the time, i really wanted to install on an Ipod, with a 100% waterproof case, and it becomes a range tool.
I try to keep my iPhone in the truck as it’s my business line and can be distracting enough to ruin a range day.

Alright, I have been playing with Strelok for a part of the afternoon, giving it another chance.
Also read on forums and troubleshooting posts.

I noticed, when I was going in truing, it would always want to change my velocity. Which is BS as I know I am doing 2700 and not 2660 like they wanted me to true with.
Then I notice in truing, I had overlooked something, there is a BC tab instead of speed.
They said my BC was around 0.492 if my data wants to match.

I go in bullet calibration, and I see my 175SMK was set at 0.505 per their data bank.
So I browse Sierras website, and my velocities are nowhere near to be doing 0.505, in reality I am more at 0.496 and lower as it slows down.
In the Strelok bullet calibrate, it has multi BC, and I input a few variables.

The end result, when inputing weather data from a certain range day visit, I am getting pretty damn close to my range card which worked with that visit.
The strelok is calibrated with exact conditions of that day, the range card is as close as I can go. I have many range cards in 0.5 inHg increments and take the appropriate card out depending on conditions.
I am definitely giving Strelok pro another chance to prove itself, as I think this is going well.

Here is a comparison of strelok card with my actual working excel card.
That day it was 74F, so we got to use the 70F column on my range card to compare.

Igor Borisov (the developer) is a very knowledgeable guy. I use Strelok Pro for many years for all my rifles from 17HMR to .338LM. I personally never had any issues with this app. New reticles are being added regularly. Here is a link to the Russian speaking forum where you can find a lot of info about this app since 2008.
