Feb 3rd 2018 In this Video I shoot the Kral Puncher Jumbo .25 to 77 yards. I shot .65 inch 5 shot group. The valve stem breaks while attempting to shoot at 100 Yards. Troy Hammer of Annihilator Airguns and Tuning is working on my gun to get me back up and shooting. Troy Hammer does some great work on Kral airguns as well as others. He created a King edition of the Kral Puncher Jumbo in .25 putting out 60FPE. He shot two 5 shot groups at 100 Yards .75inch. Amazing. He also created a .30 Caliber Puncher Jumbo.
