Thread: Ballistic truing conundrum

Re zero at 200. The further out you zero the more error you can induce. Make sure it's exactly 200m. Or is it yards? That could cock it up.
Check atmospherics are correct, scope height etc. It all needs to be as close to perfect as you can get it if your going through a trying process.
625 is also on the close side for trying. 800m is usually the standard.
How good is your shooting? We're you shooting in a position or off something that the rifle could jump slightly higher? Carbon bipod on rocks or something? Or jambing the rifle down into the ground to get elevation?
It's not very hard to induce 1moa of shift, I've seen a lot more.
