I'm not a duck hunter but I am a hard core turkey hunter and in my opinion the 835 is the best turkey gun there is. The barrel is overbored to the size of a 10 guage barrell and at 26"-28" long it is mean...I'm talkin hard hittin and very nice patterns. I have a good freind that consistently kills turkeys beyond 50 yards with a 28" barrell, mad maxx x-full choke, and #4 winchester extremes. I shot one with his gun at 62 yds... only because I knew what the gun was capable of and that bird wasn't coming any closer. (my freind was calling)
I bought a 935 before turkey sesason which is exactly the same but automatic instead of pump action. I have patterned several different loads in it and am very pleased with the results. I haven't shot a turkey at 50yds with it yet and I don't imagine I will any time soon cause I call em' in close!
It's a very tough gun and great buy for the money!
