I now use a Palm Z22 (the entry level Palm) and the PSSF program for my long range shooting.
The only negative for the Palm Z22 is that the screen needs to be shaded in full sunlight. Otherwise, it's a gem.
PSSF - Sharpshooter Friend, is a free Russian program that runs well on the Z22 and on the more expensive models.
To download PSSF, go to http://www.freewarepalm.com/calculat...rfriend).shtml
Ballistic calculator based on equations from A. Pejsa.
Support non metric units, subsonic velocities, databases for used bullets and weapon. Many features for work with Mil-Dot reticle (including come-up corrections).
- Solve vertical & horizontal corrections, needed for successful shooting
- Solve B.C. from result of practical shooting
- Database of used weapon
- Database of used bullets
- Mil-Dot calculator
- Support non metric units: inches, yards, fps, gr, inHg, hPa, Fahrenheit degree
- Different program styles: military, hunting and sport
- Solve come-up corrections (from previous shot to current)
- Show Mil-Dot reticle with POS
- Interface optimized for fast input of data"
It also fully supports metric units and mixes of metric and imperial, and corrects for input target elevation angles, station pressure, temp. etc. About the only omission that comes to mind is a lack of RH input but that is inconsequential.
