Had some time to shoot the new gun today for the first time.  I was shooting HEVI #7, and Federal HEVI #7.  I shot the factory turkey choke and a Sumtoy .562 I believe it is.  Anyway.. the Sumtoy and the Federal HEVI, 1.5oz, #7 won... 178 hits on my best shot.  I shot all the combos about 4 times. The HEVI 13, #7 was shooting about 20-30 less. 
Before I started I polished the barrel even though it was new.  Getting the barrel off the gun was a challenge... and then getting back on the gun was even worse. Why?  Well I learned one thing.. and this is important to anyone that has or is thinking about getting one of these guns.... If you install the provided picatinny scope rail (like I did)  the treads go down into the receiver a little bit, just enough to NOT allow the barrel to pull out.  You have to loosen the little screws a bit for the barrel to come out.  About 2 hours of screwing with this thing and I finally figured it out. I'm lucky I didn't damage the gun in the process. Overall I'm real happy with the pattern results.
