You'll need a very good rifle (HW97, 48mm mildot scope with 30mm tube, mag 4-16 for example, £600) and accurate shot with Crows. Pointy pellets are not accurate at the range you will be shooting. Need good quality pellets as well -evenly weighted and perfectly formed for sighting beforehand. Shooting in the air is illegal, even with an air rifle, I understand. Plus the sighting is different for the range as there isn't the pellet drop you have for horizontal shot.
