I have an s200s and have found two ways to change the power. Out of the box my gun was doing about 802ft/s witha 7.6 grain pellet and i wanted to get a bit more out of it which is done in two ways either by loosening or tightening a small screw on the right hand side just above the trigger or under the but stock, it is marked with a small blob of red paint.From what i can tell the screw under the stock adjusts how much air is released which relsults in fewer shots per fill so it is better to use the screw on the side which i think adjusts how far a valve is oppend when you pull the trigger. the further the valve is oppened the quicker the air can be released and the faster the pellet will go. Hope this is of some use to some one! Feel free to comment or ask anything!!
