kral Puncher Jumbo .25 - This Gun is Amazing! Initial Tune 46 shots 20 extreme spread

In this video I preview the Kral Puncher Jumbo in .25 I have done an initial tune to the transfer ports and power adjuster. Power has increased from 825fps to 875fps with a JSB King 25.39grain pellet. This gun will shot 46 shots with an extreme spread of only 20fps.
