I need some help with my Benjamin Krato 22 cal. I haven't shot the gun since last December. I had the velocity set to 870 fps with my chronograph. The velocity has stayed at 870 since I adjusted the gun when new a year and half ago until now. The power adjuster is set all the way open. I noticed the gun report sounded a little weak and the poi was almost 1" low. I pulled out my chronograph and sure enough the gun was shooting at 811 fps. I gave the hammer spring 3/4 of a turn and checked the velocity and it was back around 870 fps. As soon as I installed the stock and checked the velocity it was down to 845. If I remove the stock the velocity goes back up to around 870. I'm not sure what's going on here anyone have any ideas?
I have a JTS Airacuda Max in .22 cal. Before Travis (thanks again Travis) sent me the stock spacer I had a similar issue where if a vent hole was blocked in front of the trigger the velocity would drop when in the stock. On my Kratos i don't feel any air escaping from any of the holes under the action when I fire the gun. I don't think this is the same issue but I could be wrong. Thanks for any suggestions.
