Yes, I've done the search, but not wanting to read hundreds of threads, I would just like to know how much tin to add to WW's for a good mold fillout.
Casting .45 ACP and using an RCBS 20# furnace. Seems to me it was like 4 oz. tin to 20# of WW's for a good mix.
The old processer just ain't like it used to be.
Opinions?
