Can You Shoot Slugs from a REXIMEX RP 0.22 Cal Pistol?

Shooting 23gr slugs from a REXIMEX RP 0.22 Cal PCP pistol. Yes, It can be done. We tested this without cheating, just out of the box, no regulator adjustment and it grouped within a 4cm circle at 25m. This is pretty poor but remember the rifle/pistol was handheld and it was untuned for slugs.
