I have been loading 38 loads with speer 158 grain Semi wad cutter and have had no problems. However, cleaning after shooting 100 rounds of lead is not that fun. I bought some 158 grain jacketed bullets, same diameter and i cannot get the bullet seated correctly without bulging the brass. I mic'd the brass @ .357" and actually think I was shearing a little lead off when loading the swc. I have adjusted my dies and made several brass to bullet only attempts to no avail. In order to seat properly the brass neck is flared too much and then when bullet is seated the brass bulges. I feel dumb asking this but I cannot figure out what I need to do. Is it that lead is just more maleable or do I have the dies set wrong...? I am definietly no expert but I would love to figure this out. Thanks in advance.
