Knowing what your gun likes is the key. I have the same gun and shot 3-4 boxes of Hornadys out of it and they were all over the place. Luckily the next box (hastings) I bought my gun like them. It can get expensive figuring out which shell your gun likes. I have read several post saying the H&R 20 gauge can shoot accurate out to 100 yards but I can tell you from experience my H&R will not. Good luck.
