We keep sheep and feral dogs have been a problem in the past. My 3" Sp101 is what I usually grab when I check on the animals. To date its been loaded with target level 38s (SWC). I figured I should work up some more appropriate loads after seeing how little damage the 38 load administered to a squirrel.
150g@1100fps shoots to the sights well and has a reasonable level of recoil. My thoughts are either a hollow point SWC or a DEWC seated out of the case. I have the Lee 158 SWC GC mold that could be cast soft and drilled out for the hollow point. I would need to buy a wadcutter mold. My thought was that a large shallow hollowpoint would expand quickly, possibly shedding the mushroom, leaving the base to penetrate deeply.
The largest of the dogs are probably 50-60 lbs. I saw a female yesterday heavy with milk, so a new batch is on the way
