I have bought OTC cowboy loads for .45LC....
......and got everything fron 500 fps to nearly 800. (Hard to call 800 a cowboy load.)
I buy them cheap from Georgia Arms and I like the option. They are only a little bit more than buying brass from Starline and loading my own.
Georgia Arms is always at the three different gun and knife shows in our area and I have bought a hundred rounds from them every time in either .45LC or .357.
