I just won a mossberg 835 shotgun at a DU banquent. This weapon sports a #1/2 chamber and came with choke for turkey hunting. [xxfull?] Comments on this weapon and selections on choke requirments for shooting steel loads? What type of after market barrels are best for shooting slugs?? I was thinking about turning this gun in a tactical weapon, carrying it on duty in my squad car. Any comments would be welcomed and thank you.
