I have a .32 Navy Arms Mule Ear and a .32 barrel for a T/C Cherokee. Both are accurate and cheap to shoot, but both .32s are finicky to load and they foul quickly. If I had the chance, I would use a .36 or a .40, but they are harder to find and more expensive to buy. I got the Mule Ear new for about $100 and paid $100 used for the Cherokee with .32 and .45 barrels.
