Ya for sure, it is only as good as the data entered. We shot a couple rifles a little over a month ago...a 30-06 and a 338WM...both with factory ammo and both with brand new RZ600 scopes on them. Just by utilizing the factory ammo data in the program, both rifles were bang on at 600 yards so the program does work when the data entered is correct but as always, you need to shoot at those ranges to confirm.

I'm not sure what you mean you adjusted the muzzle velocity to compensate.
