If they shoot well enough for you, zero her in and go about your business. If not, try different loads. My 870/hastings like federals. Alot of guys' like coppersolids, or lightfeilds...its just every gun for itself with stuff like this. ONE BIG TIP. Get that barrel C-L-E-A-N, and I mean clean. My groups shrunk incredibly when I spent a full half hour cleaning (not counting the hour worth of waiting to let solvents soak...twice an half hour each). I would get clean patches from the barrel. Then I'd let the solvent soak and run another patch through and it would come out black so I'd start all over again. Clean every couple shots too, run a brush through if nothing else.
