So I've got a .50 cal CVA inline and I wanted to try some Lee 360gr Minie's. My bore slugged to .501. These balls are dropping at .503 and the best I can do with a Lee sizing die is reduce to .501.
Since I'm not going to war I don't need to fire 100 rounds without cleaning. For best accuracy should I try to stuff the .503's in there or should I size to .501 or should I look for a custom .500 sizing die?
Also, should the whole bullet engage the rifling or just the lower half by the skirt? Just wondering.
Thanks in advance for helping this minie noob out.
