Size of expander plugs
(1/1)
brian_a_mcmillen:
I am wondering about what diameter size below the diameter size of a given projectile should the expander plug be and is there a difference between cast bullets and jacketed bullets. Like for a .452 lead bullet….should the expander plug be .451, .450 etc. I think I need to expand my cases more to keep from resizing my lead projectiles by forcing them into a case that’s too narrow.
Ideas??
CDRT:
I use the same expander plug for both lead and jacketed bullets. Never had a problem. It's the one that came with the press, never measured it.
