Should I upgrade from my trusty Marauder Pistol to the .22 Vulcan?

"TonyT"I opted for the FX400 with it,s three position, very reproducible, power settings. At low power I can knock pests off the feeders and get almost 200 shots from a fill. I use medium power out to 50 yards with the JSB 15.9 gr pellet and for longer distances one can easily switch to high power. If you want a bullpup then the FX Bobcat would be my choice.
How would you rate the accuracy on low power? Both of the FX Bobcat .25 i've owned had less than stellar accuracy on low power. It's still good, but not as tight as i'd like. I'm torn between getting the FX 400 or looking for a sub 12fpe rifle with laser accuracy.
