New to these older guns, I picked a 2.5 inch bbl 19-3 satin nickle for 350 a few days ago. I was told not to shoot light loads like 125grain hot 357 in it. Is this true and what about the heavier loads, will it hurt this gun or is it primarily better as a 38. Also have some freckling on the gun, what can polish or get this out without hurting the finish. Thanks.
