    For under 250m MPBR is the ducks nuts.
    But when you’re out at long range and added spin drift in the wrong direction it’s a miss.

    As for why. I started with Shooter’s Calculator, moved to JBM for metric, then found 4DOF had fancy drag models. What I ended up with was confused.

    I figured I was better off trying to understand my way out of the hole than shoot my way out.
