The .32 cal squirrel rifle is a good gun.I had the kit that came with both .32 and .45 cal barrels.I lost the.32 barrel in a move, the .45 still works good.I liked 15 grains for target shooting to 25yrds,for anyting farther I upped it to 30grains of 3fff.This shot very accuratly at the 50yrds.Brian.
