Reply To: Help! Need more power from my Gamo Urban
mikebeggs, You have a better understanding of your gun than I gave you credit for. My buccaneer, unregulated, with two turns clockwise on the hst gets 30 shots from a 230 bar fill. With the 15.9 JSBs, it starts at about 905 fps and climbs to about 925 between 170-160 bar and drops back to about 905 again at about 135 bar. With the reg set at 160 bar I only get 18 shots between 900 and 910. Backing off the hst only decreases power so it isn’t wasting air. Accuracy at 925 fps at 30 yards is 5 shots inside a .35 hole. Like you said the reg is good if you want to tune for less power and more consistent spread but as you can see, the valves on these guns do a pretty good job unregulated. In my case, there are no accuracy gains in tuning down. That is why don’t bother with the reg in this rifle. Anybody who thinks they can raise their power by adding a regulator is barking up the wrong tree.
