My Benjamin Discovery .22 shoots the Predator Polymags THE BEST. JSB Exacts shoot pretty good but nothing like the Predators. Air Arms Field pellets are fairly good as well.
I guess I got real lucky how my Disco likes Predators, since I do a lot of hunting. At 20 yards I can consistantly shoot 0.2200" 5 shot groups with the front of the gun rested and my elbows on the table.
You made a good choice of pellets to try. Like the ones you chose and what others recommended - I'd recommend JSB Exacts, Beeman Kodiaks, H&N pellets, and I'd maybe even give the Air Arms Field pellets a try.
Good Luck!
