I have an old 38 sp that I used to carry with snake shot when out hunting. I cant seem to find the 38 sp shot shells that are just the length of the case with a wad holding the shot in. My chamber wont take the newer shells with the plastic shot holder that extends forward. It takes regular bullets fine but the plastic containers have no taper. I dont want to change the chamber. Are the older type of 38 shot shells available anywhere or is this a hand load only situation? Thanks, Grant
