Reliability
I've not noticed any problems with my Benelli (3 inch). I've shot everything from the Winchester AA low recoil, low noise loads which are slower than most Daisy BB guns on skeet to Winchester 1550 fps fast steel with no cycling problems. Now I didn't try to interchange the ammo but there's no need to either. Mine has been a very reliable auto. Right now it's full of corn husks, dirt and grime from 5 days of duck hunting and still cycles everything I put into it. I might even clean the gunk out before the season is over in 50 days.
I wouldn't even bother taking an 1100 into a duck blind or goose pit. I took this one to Argentina last year to shoot dove (yeah, I know a 12 ga is overkill there) and shot about 1000 rounds a day through it with their cheap ammo. I think I had maybe 2 hangups in 4 days.
One shooter had brought 3 1100s with him: 410, 28, 20. Each one lasted about three hours before they had to be completed disassembled and cleaned.
Just my experience. Tom
