Use to use nothing but 00 buck and killed a pile of deer with them. Buy a couple of 5 packs of each of the size shot you named along with #1 buck and see which patterns in your gun at 25, 35, & 45 yards with the different choke tubes. Sometimes a change in shell manufactures will make a noticible difference. I would still be dog hunting if we could get the necessary lands, but most timber companies have outlawed the use of dogs.
