N3 ball clipping and chopping

[TKcustoms]

My N3 has been blending paint suddenly. It was fine when i first got it. I tried changing my insert to .688 and while it did improve a little it still doesn't work right. If i put a stack of balls in the feed neck and shoot, it will shoot the ball out of the feedneck somewhere between 10-30ft.

Anyone have experience with this or know how to fix it? When it does shoot right its at 270 fps and i haven't touched the regulator

Hmm, I do know bore matching is pretty important. Do your inserts slide in and out easily? Also have you lubed the o rings on the part of the barrel that moves?

I ended up just doing a full teardown and relube and it seems to be just fine now with the overbore
