First off I think that ww are still a great source of lead if you have a place to get them.It seems more and more it is not just the ww that are getting hard to find.Or ww in general are getting more trash than lead making them less usefull for the time it takes.I have given up on ww myself the price around here is just to hi for what I get in a bucket.So Do we really need ww?
Just some random thoughts.
I have found a lot more pure or close enough than anything else.With some solder here and there.I have been able to find or trade pure lead for tin.I have went to using super hard.Two things here made things easy 90% of the solder I get is known and we know what super hard is. Sheet.Sheathing and Pipe are the most common things I find and are pure or close enough most of the time.this works well guestimateing .
BNE has been kind enough to do the work on testing all kinds of ww.it is the modern day where testing is out there for all of us.Be it at you local scarp yard or a member here.I find it a very usefull tool in my casting.Saves you time an money when you know your alloys.you can make the same alloy over and over any time you like.
So who needs ww from what I have read from the infor here on BNE threads.Modern coww is about 3% antimony and .5% tin.So if you use the tried and true mix of adding 2% tin to coww then cut that mix with 50% pure lead you get bout 1.5%tin and 1.25%tin.great for many shooting needs.
so get looking for some type metals or watch for the sales a few times a year at rotometals.you can get on there email list on there website.
after all ww are just another alloy
Just my way of lookin at lead and alloys.hope it is of help to the lead addicted here.Happy casting and shooting all.
