Use the predator choke you have, and buy some Winchester longbeard shells as previously stated. They shoot well out of just about anything, and won't break the bank. If you want to spend a little more buy some hevi 13 6s or 7s. 3" 2oz, or 3.5" 2.25 oz. The nitro Ray shells are over priced. They might pattern a little better than the hevi 13 shells, but not for as much more as they cost.
