So I am doing the final updates to Gravity Ballistics with Marc and Chris. If you watched out Live this week, we discussed the Gun Number vs the Drift Number.
So let me explain,
We use the Gun Number to describe the wind deflection of the bullet based on it's G1 BC. The first number in a G1 BC is the wind deflection in MPH, so a .5XX BC is a 5 MPH Gun, so you think in increments of 5 MPH. Also in that same breathe, if you add .1, .2, .3, etc to the hold, it also matches the Wind Speed. Once you hit 10MPH you simply double the hold.
This seems confusing to some, and often takes an extra day to understand exactly how this works. (Granted this confusion is with newer shooters) but we can get right to the point with wind. No more it is the Tired old line about getting a case of ammo and practicing in the wind, as that does nothing for someone who has not frame of reference and there is more than one wind formula.
But Kraft Quick Wind and Gravity Ballistics compliment each other in their respective planes. Being able to clearly state and simply the process is important to our style of teaching and operating. Just about everything we do with both Gravity Ballistics and Kraft Wind we do in our heads. It's not only on the fly, it's improving the results with each shot. You are reading the results on target then using those results to do the math. It's not math to get a result then an adjustment to align it in the predictive solver. The shots inform the calculations.
So we are moving to use Drift Factor, for the Gun number to better describe the action taking place. The best example we used during the live is a very light fast bullet vs a heavy bullet. Velocity changes the BC so a higher velocity will increase it, while slower than advertised with decrease it. You can have a .4XX G1 but send it more than 400fps faster so it's now a .6 and not a .4
The success we have seen in just the last month with our refined lessons have paid huuge dividends on steel. Those who have taken the course are getting next level X - Y hits on steel. Its amazing.
Guys are making amazing calls, and the Gravity Ballistics app with the Kraft Quick Wind feature I am testing is so easy. It just works.
The beauty of this,
Super easy Numbers you can do in your head
No need to use a ballistic solver inside 1000 yards once you gather your data. Memorize 300 to 1000 and you are done.
Feeds a solver Pre-Trued Data to align it fast and easier. Then you can successfully travel without needing new tracks
Minimal shots needed for success.
NO INPUTS just use your dope and the impacts on steel. The only number we "use" will be the drift factor for the wind.
