My Pedersoli .32 Pennsylvania shoots two loads very accurately. My early season squirrel load is 15 gr of 3f with a .311 ball and a .015 patch lubed with mink oil. Close to quarter sized groups at 25 yards. Later in the season, when the leaves have started to fall, I switch to 25 grains of 3f with the same ball and lubed patch. I get 1.5" groups at 50 yards with this load. That is about as far as I will shoot at a squirrel with iron sights and my ageing eyes.
