Try some Remington Express 00 buck. Mine patterns very well with it. If yours don't Federal with the Flite Control wad will pattern very tight.I love my Protector. The only down side is that the barrel is quite short and has no choke. It shoots a pretty wide pattern but is good for home defense and shooting slugs. Some Remington 870 parts will interchange with it but a barrel from an 870 will not. I've shot mine alot and never had any feed issues with it.
