Thread: calculator able to predict projectile pass height over variuis distances

2. There is no way to know whether a predicted solution from a ballistic calculator will allow you to hit a target at an extended range without actually shooting at that range. You can check that your scope will track the correct adjustment to apply the solution, but you cannot test the validity of the solution at 91m.


What kind of targets are you hoping to shoot at 600m?

Thanks for your input
do you use Gordons reloading tool ?
I can send you the typical results for the load including the shot group image and calculation
I shoot 3 rnd groups ( because the rifle is a sporter and the barrell heats up real quick and acccuraccy drops away )
I have a big black stag in mind that keeps showing himself 600 mts away across a farm ...
