wow, how exciting watching the grass grow on the range!! how about pic of the rifle, that I have never heard of, the ammo, the shooters position body and hand etc etc. maybe some info on specs, trajectory, wind compensation with this cartridge etc etc. this video showed me nothing but grass growing.
