Fx Airguns Panthera 700 mm long range shooting to 500 yards

I was trying a 500 Yard airgun challenge with my Fx Panthera airgun rifle. The challenge is to shoot six ballons 12”,10”,8”,6”,4”and 3”. My GoPro camera froze and a didn’t get the introduction explaining the challenge and the shooting of the challenge. I couldn’t repeat the challenge because I only had three balloons left so I decided to shoot three five inch balloons at 500 yards. I’ll repeat the challenge on another day.
