i can confirm the following as accurate
the velocity . i make the ammunition and measure the speed ( over 100 rnds )
the target distance is 91 mts ( 100 yards )
I do not have acceess to a range that has a 600 mt mound and butt , hence the theoretical and practical testing at 91 metres . None of the ammunition has actually been fired onto a 600 mts target
the scope height is 1.85 inch above the bore .
the rifle shoots 1/2 groups .

I am fairly carefull to collect legitamite enviromenat conditions , so the weather statement is reliable as well .
I am pleased that the elevation adjustment looks to be correct for the scope adjustment at 51 clicks .
However the question remains , if the projectile i have described , and motivated to 2950 ft/sec , passes 33.5 cms high about the 91 metre target, will the arc of the trajectory, see the round fall into a circle of 12 inches at 600 mts ?

1. 1/2 groups for how many shots? Unfortunately the reality is that a, or a series of, 1/2 inch 3 shot group provides imprecise information about your mean point of impact and you can expect "noise" in your down-range results as a consequence. 5 shots is little better.
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?
