Thanks , didnt realise it was based on the 14.5, just thought it was a juiced up Russian 12.7, which does have similar ballistics to the 50 BMG.
Still has loopy trajectories though, which makes long range calculation and adjustment difficult, most scopes just dont have the adjustment range to compensate, which is why most extreme long range target shooters tackle targets from high elevation.

It really isn't very loopy at all

Run it through a ballistics calculator.
750 gn Amax @ 3200 fps BC of 1.05
The drops are extreme, around 230 METRES.

Handy piece to put on your FAC, explaining how green it is, as in saving having to using a vehicle to go to the range. You can just open the back door and shoot from there. If its within ten miles.
