I always used to shoot Brenneke Rottweils with great success but would lose a little bit in accuracy in my rifled 20" 870 slug barrel. I now shoot the Hornady SST Slugs and they are about as accurate as you'll get, in my mind. The Federal Premium Barnes expander slugs are very good too, and they are all that my brother will use.

I also agree with ultra man. 3" ers usually pattern a little rougher than the 2-3/4" and the Hornady SST's were only available in 2-3/4" last year when they came out. Don't know about this year....
