.38 Speer hollow based wadcutter, loaded in a .357 case & 3 grains of bullseye in a 10 Contender bbl. This combo would agg an inch & a half at 50 yards. Perfect for squirrels, less meat damage than a .22 HP. Just pokes a hole right through the body & they drop like a sack of potatos. Also worked well on large feral dogs.
