I was wondering if there was any tips on a mold i recently bought. I recently bought a 200swc 45 rcbs mold off of eBay as used but of course as i could tell it was basically new. Well anyways im having trouble keeping the bolt for the sprue plate tight. I know there is a set screw for it and i have messed with that trying to get it set a few times. Also i have problems getting the mold to open it seems stuck and that i have to tap the handle bolt to get it to open. Also bullet drop but im going to try Kroil soon enough and hope that helps. I went to RCBS figuring all the lee type problems would be past me but not so.
