I'd like to make everyone aware of a new ballistic solver called the 'Whiz Wheel':
Accuracy 1st: Sniper Training & Products
The Whiz Wheel is a non-electronic device that calculates ballistic solutions out to transonic range for any small arms bullet.
*Density altitude calculator
*Meters/MILS or Yards/MOA output
*Trajectory prediction within 0.1 MIL or 0.25 MOA resolution
*Wind deflection for any speed and direction
*Leads for engaging moving targets
*Corrections for inclined shooting
*Ability to 'true' the solution for variations in MV or BC
The tan colored sleeve is general, meaning it works with all wheels. The wheels are interchangeable laser engraved plastic that are custom made for your specific bullet, MV, sight height, and twist rate. Each wheel provides a full solution for a single round. Different wheels are required for each new round.
Solving the wheel is very simple. Start by solving the density altitude (DA) with the small wheel, or getting it from a Kestrel. Then line up the DA with the range, and the wheel outputs drop. The drop can be corrected for incline via the table on the back of the sleeve. The back of the whiz wheel also calculates the lateral solution elements including wind, spin drift, and moving target leads.
I was heavily involved in the development of this wheel and can vouch for the accuracy of the solutions which are generated with a point mass solver and measured G7 BC's. Furthermore I'll be available to answer questions about the whiz wheel on this thread.
