From doing some testing with hammer spring settings I have discovered a misprint in the Origin owners manual. It states that " One complete turn equals a change of 150-200 fps". It should have read that this is what you can expect,150-200 fps, throughout the entire adjustment range of 6 turns. I also discovered for me that my best accuracy using 16 gr. pellets was with the hammer spring backed off 5 complete turns. This gave me a 811 avg. fps at this setting.

You get 6 turns, mine only has 2.5! Maxed out it's sending CPHP's at about 930 with good accuracy, quarter or less groups at 40 or so yards.
