counter clockwise increases the regulator pressure, clockwise lowers it. If you are used to nuts and bolts like I am you want to turn the screwdriver like you are loosening a screw to go up in regulator pressure. I've tested a wide range of regulator settings in my P35-177 to see if it affected accuracy and my conclusion is it doesn't seem to. I went back to a setting about where it came to me. That gives me 875-900 on it's preferred H&N Baracuda Match pellets. Accuracy I call good but not excellant. My best 30 yard challenge score with it is a 194. I haven't tried H&N Baracuda FT pellets in it yet, however. But it is easily squirrels head accurate at over 30 yards. JSB 10.3 grain are pretty accurate too. I had a tin of Crosmans that shot well but the next two shot quite poorly. I traced it to wildly inconsistent head diameter. Some report good accuracy with JSB knockout slugs but mine throws them out wildly. They must not be engaging the rifling. It's a nice shooter with the H&N Baracudas, however.
