Thanks mate. This is just a small part of what goes into an accurate long range shot and it gets very complicated. The mathematics is extremely difficult and often the time isn't available to make the calculations so a ballistics calculator is is used to get a field firing solution.

Having said that, the ballistics calculator needs information to be able to spit out an answer and it's that information that determines how accurate the FFS is. Things like barrel twist rate, projectile weight and type, ballistic coefficient, scope height and offset from barrel, density altitude (altitude, humidity and temperature combined), azimuth, angle of shot, range, plus the wind direction and speed of course. (Plus a few other things)...

Then one needs the right equipment, set up correctly. And accurate ammunition which factories can't really provide...Each round needs to behave the same. I take a lot of care to ensure the seating depth of each bullet is exact across all my rounds, that the exact amount of powder is in each one based on my load development research and that the the standard deviation (SD) in muzzle velocity between rounds is under 10fps.

I've been doing this for a long time and have had some of the best training available. It can certainly be taught...But not on steem. I write these only for fun and to promote to people that shooting isn't just about beer and bad choices. It's an activity that requires a lot of effort, dedication and understanding, especially when one makes their own ammunition as I do. That's a whole different thing altogether.

Thanks for being interested.
