So far my copper experience is pretty limited, just working with a couple of spools of #2 babbitt wire. Still learning and will enjoy reading back through the thread. Thanks to all.
good cheer, just what the heck is that?

oh, duh... now that you point it out to me, it should have been obvious, but I've never heard of it recrystallizing like that. interesting

oh yeah, you should see inside my water heater.
bonus is my pipes never leak.
I've been through both of these threads on Cu alloys and had a thought.
Could you take soft lead, add brass case trimming shavings, remove the zinc, then add linotype? It would solve a number of issues, with Sn not being removed from the alloy with the Zn, and still add Sb and Sn in a known alloy that adds hardness with the Cu/Pb?
I realize this is a gross simplification, but seems to solve most of the issues. The only open question would be ratios.......
I ain't tried brass [thought about it]
but initial testing was done with a higher tin solution alloy and tinned speaker wire cut into small pieces.
the problem would be the high melting point of brass I think, even copper wont mix unless it is tinned or it iss in the form of copper sulfide, like Zepps is

I have noticed that copper laced boolits have a harder, slicker "skin" to them, even if the BHN itself isn't very high, mine are around 13.5 for example. has anyone else noticed this? and do you think that it helps with ballistics, wether it be pressure-wise or accuracy?

Someone on one of these threads added brass case trimmings and said they were successful.
I'm looking for cheap, easy, and successful.
a 2lb bottle of Zepps is only like 11.99-12.99 at home depo, aand that goes a long way. it is 25% copper, so you can figure out easily how much you want/ need in relation to the zinc and what you want your finished cu % to be

NOTE: Eutectic Lead-Tin Solder at ~63% Tin Will Disolve some Copper at SOLDERING temperatures. In Electronics Industry we went to a Semi eutectic Alloy Containing Silver to stop the removal of Copper Fine Line Traces on Modern Design Circuit Boards.

so, for a 3sb/3sn/.25-.35%cu alloy, what do you think would be the best choice for hollowpoint pins, short and fat, long and skinny, or other? I was thinking a hp shaped like a martini glass would work good ( short sect. of wide opening, then a longer "stem" of maybe .10 dia ending in a rounded point), if you can picture what I mean? and do you think this alloy should be heat treated or quenched for 2100fps?
