I've killed hundreds of squirrels, rabbits, and such with 38's, mostly from an 1894C. I used to use 4.5g of Unique, with a 125g SP, but I stopped shooting 38's in 357 magnum revolvers/rifles. A good replacement for this combo is a 125g SP, and around 6g to 6.5g of Unique ignited by a magnum primer(for consistency), and loaded in 357 cases.
