2nd testing video of this custom KC-02 lever-action sniper rifle build, running on CO2 gas mags at 2.28j with 0.45g ammo on an 80m range with a virtual torso target.
We've changed the hop rubber from a 60deg Flamingo hop rubber to a 50deg Flamingo, to pursue the theory that the BB is "skidding" or "skipping" over the contact patch due to the high acceleration needed to achieve the desired muzzle energy with a 380mm inner barrel.
We also used a bipod for this shooting session to increase stability, and we have a virtual target overlay that is scaled correctly for a person at that range.
Whilst we still had a portion of flyer shots, we saw overall batter accuracy, around 70%, which is incredible performance at this range.

Weeks of careful assembly and testing have been poured into this build, you will not find a higher-quality KC-02 build with more attention to detail and performance in this world. The barrel group alone is worth more than £500.
