i found a free reloader. its a early 70's RCBS J.R.PRESS. it was my dads and it has not been used in over 20 yrs. its a single stage press with scale, trickler, some dies (.38 special, 30-06, .357, .41 mag, 45 acp) some shell holders, de-burring tool, powder measure. everything is RCBS. will any brand of dies fit the RCBS? i need a 9mm and .243 dies. i know i need a tumbler. what type of agent should i use in the tumbler to get a good shine on brass? i picked up a 1996 speer reloading manual at half price books. do you think anything has changed in old to newer manuals? if there is anything else you think i need please let me know. thanks
