Hornady makes some of the best mass produced factory ammo, if not the best ammo, in the world. Both those ammos you mentioned are excellent.

Try the Speer Gold Dot short barrell .38 ammo

Lastly, Buffalo Bore probably makes THE BEST ammo - check out their offerings in .38 special. They have about 8 different offerings and a good description of each.

CorBon is, IMO, too hot of a load
