I do like Dave Rase. !/16 steel for RR pipes, trigger guards, and Steel ram rod tips; 1/16 brass for brass ram rod tips; 3/32 steel for barrel pins, triggers when pin is in the wood. The steel peens easily as does the brass; If a barrel or ramrod pipe pin is loose, just put a bend in the middle of the pin. A lot of music wire is too hard to peen nicely or bend.
