I was wondering if anyone could tell me how hard the steel used for their powder through funnels are? I want to make some custom powder funnels and am looking for a baseline. The options of steel I have on hand are 12L14, 4140 (Heat Treated ~28-30RC), and then I have some A6 that I can harden myself if need be. Any advice is appreciated!
