New Whiz Wheel Ballistics Solver for Custom and Standard Loads
Product Preview by Bryan Litz
I’d like to make everyone aware of a new ballistic solver called the Whiz Wheel. The Whiz Wheel, from Accuracy 1st Development Group (Accuracy 1st) is a non-electronic device that calculates ballistic solutions out to transonic range for any small arms bullet. This device, similar to a circular slide-rule, is in the process of being adopted by several military units as a back-up to the electronic PDAs, and even as the primary ballistic solver since it’s faster to get a solution compared to the PDAs.
Whiz Wheel Solver Features include:
- 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
- Spin drift
- Leads for engaging moving targets
- Corrections for inclined shooting
- Ability to ‘true’ the solution for variations in MV or BC
Use Different Wheels for Various Cartridges and Loads
The tan colored sleeve is universal, meaning it works with all load-specific wheels. The wheels are interchangeable laser-engraved plastic items. Accuracy 1st offers both “standard” wheels for popular factory-loaded ammo types, as well as custom wheels tailored to your specific bullet, MV, sight height, and twist rate. Each wheel provides a full solution for a single cartridge type and load. Different wheels are required for different cartridges/different loads. This is because the wheel’s solutions depend on bullet BC and muzzle velocity.

How to Use the Whiz Wheel
Finding your come-ups (and windage corrections) with the Whiz 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 the Whiz Wheel and can vouch for the accuracy of the solutions which are generated with a point mass solver and measured G7 BCs. If you have comments or questions about the Whiz Wheel, you can place those in the comments section for this Bulletin post. I’ll try to respond to your questions, time permitting.

Whiz Wheel Pricing for Standard and Custom Loads
To order the Whiz Wheel go to the Accuracy 1st website. A Whiz Wheel Solver with one (1) custom wheel for your load costs $54.95 for civilians, $44.95 for LEO/Military. Each additional custom solver wheel, set up for your specific load, costs $24.95 for civilians, $19.95 for LEO/Military. If you shoot factory ammo, you can purchase the Whiz Wheel with one standard solver wheel — $49.95 for civilians or $39.95 for LEO/Military. A Standard Ballistics solver wheel (set up for a known production load) costs $19.95 for civilians, $14.95 for LEO/Military. Accuracy 1st also offers a package of Solver Sleeve plus three (3) standard wheels — $69.95 for civilians, $49.95 for LEO/Military.

I see that this is a great product.
I live in europe and we use other units like C°for temperature, m/s for wind and meters for altitude. I think that it would be great idea to be able to order customized sleeve because people have different setup and prefer to use different units like I thin still today most of people that use the metric system for range also use MOA on their scopes. Some prefer to use feet for altitude but C° for temperature. It would be great to order sleeve with the units I prefer to use and then the Whiz wheel with the combination that my gear is, like MIL and Yards or MOA and meters, and of course it has to be calculated to the units of the sleeve. I don’t know how complicated it is but sure it will be great.

I was going to sign up but saw problems right away with your site. Went to your Whiz Wheel link: Site is in black background and is all but impossible to read, or even make out images.I suppose they think it is dramatic, like military wannabees tend to gravite towards. I then clicked on pre-order and got to an add for a scope leveler. Apparently they are more concerned with presently a dark image, literally and figuratively, than conducting business.
Interesting product.
I really don’t want to sound like a kid being bullied but I feel like Jeff is not playing nice nice. It costs about 5 bucks to mail this to Canada but he charges 29.95 And there ain’t no discussin it. I have no problem with paying the price for the product. Just fail to understand why he he has to screw his northern neighbors around.
