A year ago I shot these groups from fifty feet off a rest. The PC did not perform in any better fashion than my MOE version.
I did try a variety of ammo that's not used on the target shown with varying results and surprisingly CCI Blazer grouped very well.

To think that the 15-22s can be match grade isn't an accurate assessment of what they are designed to do.
They're a fun gun to have and I've had nothing but good things at the range.
BTW, I sold the PC and bought a Sport and couldn't be happier.
