I'm getting ready to mix up another big batch of bullet metal and am about out of 50/50 bar solder. A bunch of youall seem to be using lead free solder for your bullet metal mix, but all the lead free solder i'm finding is alloyed with Selinium and copper or silver. Which one are you using or is it time to just call Rotometals for some Tin? I can't find any 50/50 locally from the usual sources.
All help is appreciated!
