Once I get my Form 1 back from the ATF for my Scorpion I'll be PCC ready. Submitted it back in February. So I'm sure I'm still a ways away. Busy keeping my fingers crossed that once they get through July's Form submissions it'll speed up.
I think you're right. Once they get through the period from where they changed the trust laws...wait times should theoretically drop like a rock. The number of forms submitted third quarter 2015 until now have been pretty low, with everyone hoping the HPA would be coming through.
So far I've only shot 2 matches with my PCC. I am positive that I am faster with my Limited gun, but PCC is just plain FUN to shoot! I'm highly considering SBR'ing my Scorpion. I think it would be highly advantageous in certain situations.
For example, the Match Director this month (which was me) set up a stage with targets about 160 degrees from each other. It seemed like an eternity swinging from one to the other. I've never shot 3-gun, but I may not be "driving" the carbine hard enough.
