I'd definitely try any winchester load in #6 shot. I got a kicks .670 choke from a member on here for my 20" barreled 835 and though I haven't gotten to shoot a lot of loads through it yet I did put a win supreme 3" 1 3/4oz #6, a win double x 3.5" 2 1/4oz #6, and a Kent 3.5" 2 1/4oz #6 through it and they shot nicely. The double x was a smoking pattern with 160 in the 10" if I remember correctly but all were deadly at 40yds. Would have shot more but only had a few of each winchester.
