I'd save the lead 38's for short range plinking. If you really want a 150 yard capable 1894CS, it pretty much has to be using 357 mag loads. I have only shot a few lead 38's out of my 1894's, mostly just to shoot up an odd round or two laying around. The ballistics of the 38 are pretty poor which would make the long shots difficult. Some have also reported that shooting a lot of lead 38's leave a ring of lead in the chamber due to the bullet jump. This then may impede the loading and shooting of a full length 357 load. Loading the lead bullets in 357 cases with 38 special powder loads might be one way to get around this problem.
