Somebody say P90.
+1
TM P90 is the only way to go, lows caps work the best as High caps are known to have probs. If you find one, throw in an Hop-twist barrel ,bring your FPS to 350-360 and watch it hit anything in your crosshairs. I found that using this barrel over an tight-bore really works very well and has so over the past year.
