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.
