So far both of my guns group 1500fps slugs and 1900fps slugs the same. That's after sighting it in between the two different rounds. I guess I should have said in my earlier post that the Buckhammers were for rough/getting it close sighting in.
Actually the two different rounds were only off by max 2 inches @ 50 yards
