I just got my royale 400/177 back from AoA. they did some work that required removing the barrel. shooting some groups and i was getting some strange fliers. this gun has never had a problem in the past and was dead accurate. i inspected the end cap and saw evidence of clipping. i've drilled it out and will test tomorrow. so my questions are; why do some pellets clip, while others shoot just fine? also, what could have been done when they reinstalled the barrel to cause this? i did check the screws holding the barrel and they are tight. suggestions please!

gun on a table with the rod hanging out a couple feet and see if the rod line's up with the barrel.The jag has to fit snug into the barrel at least 2 or 3" maybe rap some masking tape around the rod to snug it up?

My Independence clipped when I first got it. The shroud is centered on the barrel via brass stand-off rings and the cone at the end of the shroud is threaded into the end of the shroud. I suspected that the issue was a tolerance buildup and did the same as you, enlarged the hole slightly, no problems since. Since the clearance is small, slight deviation in the assembly could have pushed it enough in one direction to cause it to clip.

Bingo!!!
It would appear that some 'More Attention to Detail' at the shop, prior to return shipping, could have eliminated this problem altogether.
I have had ample opportunity to experience this very same problem in my own 'Experiments' in decibel attenuation devices.
A simple twisting or turning the device on the end of the barrel a few degrees in either direction would 90 % of the time clear the problem. Too bad the guys at the shop did not attempt this simple test and solution prior to return to customer.
These end pieces are very Finicky sometimes.
