So I guess it's hit or miss with the supercharger, mostly miss. One suggestion for when you file down the screws if you don't have a tap and die set. Put a nut on the screw first before grinding, it protects the threads and then when you take the nut off it shapes the threads.
I've got a good one in .177. I've had it for a few years now. Below is rested @10 yrds, 5 shots with cheap Crosman wadcutters and a $30 red dot.
Did you fix the screw issue? I was thinking about it after looking at how close mine are to the cocking arm, a simple washer would bring it out--no need to file the screws. But then again, is it a screw that could take a washer under it? Had mine out recently after new scope mounts installed... @20 yards best groups were .41" for the CPUM/ .61" for the jsb 7.3rs/ .99" for AA 8.4/ .71" for cphp. Looks like somehow I ended up with one of the few ultra accurate superchargers, perhaps the .177 version is better than the .22?
