About this app

Strelok is a ballistic trajectory calculator.
Small, handy and accurate. Field-proven accuracy since 2001.

Supports imperial (yards, feet, inches, etc) and metric units. MIL and MRAD - this is the same!

Input all parameters, push button "Calculate!" and you will have vertical and horizontal values for rifle scope correction.

Also, you can select reticle from list and see wind and distance corrections on reticle without turning knobs. You can send by e-mail the reticle image with holdovers and ballistic table.

All new features and reticles will be added to my new paid application Strelok+ Already now you can use in Strelok+ reticle scaling to your scope magnification (if reticle is placed in second focal plane). Paid version have 10 rifles (with 10 cartridges each). And many new reticles.
This free version will not be updated any more.

You ability to export rifles (with cartridges) to xml-format file (can be edit with usual text editor) to easy migrate to Strelok+ (or iPhone).
Move this file to StrelokPlus folder.
On Strelok+ import this file (rifles.srl) to get your rifles.

As a semi-competent shooter just getting into long range, I find the features here full of depth and very useful. All the inputs you would expect are there, with many someone like myself didn't even think were pertinent. Do your part and this will get you on paper at range, even as a newbie like me. If your reticle isn't listed, or you (like myself) want to future proof with further input capability and storage for rifles/loads, just get the pro version. Igor answers questions VERY quickly too.

This is an exceptional ballistics app. It's easy to setup, maintain/ edit and is dead-on accurate. If your inputs are correct, then Igor has you covered. I took a new Remington 700 in 6.5 Creedmoor, Sierra 130 SMK from zero to 1,349 yards in 31 rounds. A competitor app 4DOF (free version) may be popular and even sexier looking, but it's buggy and IMO, not intuitive to setup. Strelok may not be 'pretty', but it's an elegant app in its simplicity and ease of use - and it works.

Update: Programmer responded with a quick "fix". I figured out how to back up data in case of another software issue! GTG. (Earlier: I really like the program but for the last four months, every few weeks or so all my cartridge data is erased.-- meaning time consumed in gathering data is wasted. I remove the app and then download it again and re-enter all my data ..and I haven't figured out the pattern of when the wipe will happen. I can't trust the app so I am removing it for the last time.)
