RE: Mossberg 835 ULTI-MAG
I will admit when I'm wrong, I did go off on a tangent, You are going to have to expierement with shells, like other said each gun is different, I've owned 5 of them , each gun shot great with a comp-choke and 6's. I would try those federal x-tended ranges 3 1/2 , they shoot alot better than others without the kick. As for a choke .655 or .660 with 6's. Everybody has there opinion, here's mine. I may not have 30 years of expierence but I live for this stuff and cannot deal with less than perfect products that don't produce. Believe me I've spent alot of money on this.
