When I first got it, I was trying to use 1oz shells and just kept getting frustrated but now that I have this thing cycling 1 1/8, I have not tried to go back to something lighter - could have been a break-in period perhaps...I was thinking about getting an M2 but now I've decided to just get the work done to my SBE2 and just have one shotgun. I ran into issues with getting my hands on an AR rifle with the shortage of parts that I ended up with three rifles now and don't want to repeat that mental madness. Since the barrel is ordered, I just need to figure out if I should go with Triangle or Taran to work on the loading port...
