I honed the barrel to a mirror finish on my 835 Grand Slam and it will pattern pretty much any shell Ive tried with the .690 Mossberg factory turkey choke.

A shell Ive shot great patterns in several guns is the 2 3/4" #5 Winchester XX and they dont cost you $5.00 a piece. h.h.

If you're not a hemorrhoid, get off my butt.
