Interesting take, @ObiJohn, and I could fall for your "close enough" conclusion had I not witnessed the thousands of waterline strikes I've seen while employing this 'reversion to the mean' method of gathering data with shooters bringing heavy, light, fast and slow calibers of high and low BC...
Elevation - So when you hit center water line line at each yard line you are going to ask how the 90 or 270 wind affected your data to get that center elevation strike? That's an assumption that it did. While you are assuming, account for spin drift and corialis as well. Use the ap on the...
Taking first-come-first-serve orders. * Production hold means I am traveling and unable to make/ship bags at this time. Will be *Shipping again soon. Watch for the thread title to change. This meticulously designed and produced bag has made thousands of shooters more consistent shot-to-shot...
This range is a hidden gem. Had a great time here the last three years. Make the drive this fall for instruction and shooting memories you will never forget. The 3-Day is OVERflowing, so... we are adding a course! Frank and Marc Complete 2- DayCourse in Fundamentals and Gravity Ballistics. You...
The Gravity Ballistics Ap does not/ will not be built around a 50-yard zero because it was developed for center fire rifles. Nor will I break it down to 50 yard / 10-yard increments because the Ap, in its entirety, breaks down the drop in a way that any unknown distances can easily be...
Don't use it as a crutch. KNOW your home range data and your grasp of drop and gravity's effect on your round will begin to expand, allowing you to spend more time in sight picture and less time staring at your kestrel. And 4dof needs truing, make sure you nail that down before you begin to...
50-yard zero. Make it Precise and accurate 70-yard data __?__ x 2.28 = 90-yard data. 90-yard data ___x 1.625 = 110-yard data 110-yard data ___x1.42 = 130-yard data 130-yard data ___x1.29 = 150-yard data 150-yard data ___x1.25 = 170-yard data 170-yard data ___x1.20 = 190-yard data 190-yard data...
The reason I have not codified the multipliers for .22 LR is because a zero range is not universally accepted as it is with the 100-yard zero in centerfire. Some use 20. Some 25. Some 50 yard zeros. Changing the zero range affects the multipliers because it affects the data slightly.
Yes. First step is to be comfortable with and be able to recite your home-range data instinctively. That leads to understanding your drop between data points, which makes odd-range data more intuitive and not solver-necessary. Yes, easily derived. 20-yard zero, then data every 20 yards to...
In the process you describe above, you have theory everywhere but 100, 500 and 1000. If you start at 100 with Gravity Ballistics, you will have data at even yardlines all the way to 1000 based on hits, not theory and you will not need to manipulate your wrong M/V or BC because Gravity...
Precision is the wringing out of fundamentals, low standard deviation ammo and barrel harmonics. Seeking consistency in all aspects. Precision relies on consistency. Accuracy at the point of aim is a mechanical function and relies on your scope's ability to deliver precise movement of the...
