Just got my Tech Force 78 Gold Series (QB 78 Deluxe) today and immediately began shooting, after cleaning the barrel. Shot well but I wasn't keeping track of shots fired so I finally got to the point that the last pellet wasn't fired out of the barrel because the gas pressure had dropped too low. There wasn't anything obvious that indicated that point was approaching, just finally a dud shot; really obvious that the pellet wasn't expelled because there was a significant change in sound of the shot. I had to push the pellet out from the muzzle since there is no easy way to remove the bolt so pushing from the chamber could occur.
Does anyone have any handy ideas for preventing this happening in the future? I know I could keep a shot count but is there anything other than or in addition to that to help prevent this problem? |

When you get used to the gun.... you will notice the change in sounda it runs out of CO2....
Instead of pushing it out next time.... just put in another cartridge and fire it out....

I considered that but this gun locks the CO2 chamber cap until the pressure drops to almost nothing. The pressure that remained when the dud occurred was too low to push the pellet out of the barrel but too high to allow removal of the cap. The instruction booklet indicates that the way to release chamber pressure is to repeatedly cock/shoot the gun until the pressure is low enough to allow cap removal. I suppose I could do that, even with a pellet in the barrel; it might even eventually push the pellet out. |
