[Sandy]

Well, I've just kept the one pound spool.  I can always use it as a tin rich 
additive for making cast bullet alloy, that way it won't be wasted.

Stuff is too damned hard to work with so I quit trying to use it after 2-3 
tries.

Guess I'll cast some .380 ACP or .45 ACP bullets with it!

73,
