i have many older rifles that i wish to shoot using reduced loads and cast bullets

several indian era trap door carbines
4 digit rod bayonet springfield
WWI issue 03's
lever action from black powder era
civil war 58 cal

the question is, (predicated on the fact i have some dies) lyman dies for older calibers , i will need a lyman die for heavier 45 70 load and 44 load,
in my limited experience i would need round nose, and do i need to invest in sizing the cast bullet? i have a fairly good supply of lead wheel wts.

do not want to make this a life endeavor but just some casual shooting with reduced loads at 100-200 yards against gongs,,, kinda fun hearing the bang then the ping i have several ten inch steel plates and at 200 yards gets interesting
i used to have a fellow that cast bullets and i could get 30 cal from him and these had gas checks on them,, are these really critical??

educate me. i am thinking lead pot, ladle, molds, what else

regards
