Hammerli Pneuma hammer spring adjusting

[Pepper]

Since it looks like my new Streamline is gonna not be in pdog hunting mood for awhile I’m considering adjusting my hammer spring on the Ole Hammerli Pneuma single shot 22. Where is the adjustment and which way to tighten a tad ? Any tips or info appreciated!

you have to turn the hammer CCW to increase the power but you also have to "lock" up the hammer to do so. it's accessible from the side of the gun. If i had it in front of me i would do it for you. just don't go crazy and over tighten. you will probably want to crony the gun as you do this. 

However, here is one of the better videos on increasing the power of the Pneuma. I know its a Hatsan. but they are one in the same.

1 full turn ccw gave me a pretty flat string of 850s. Can’t believe I’ve had this gun for 5 years and never tweaked it
