Soder/ yard sale score

[bigbird1]

I got a box with about 20 full rolls of soder at a sale for 5.00, most is 50/50. how much do I add to my wheel weights, how would you use it? also there is a bunch of tins of silver soder, is this of any use in bullet making? also there is 3 new boxes of lead free soder , is that 100% tin? thanks in advance.

Use 2# of 50/50 to 18# of WW metal for Lyman #2 alloy. 1# will toughen your WWs if you quench and still make them harder than the hammer of Thor.

SCORE! :mrgreen:
The lead free I have is 95% tin/ 5% antimony.
I add about 6" per 2 lbs of ww. I don't water quench or heat treat. I add to assist fill out.
The big boys tell me if you get too much tin in your melt, it overbalances the antimony and you get softer boolits.

It is my understanding that adding more tin than necessary for a good fill out is just an inefficient and wasteful use of your tin. Tin is the costly alloy in your wheel weights. Half pound spools of 95/5 solder has jumped $3 from my last purchase
back in early May.

I add about 3" per 20lbs. That is if the castings are not filling out like I prefer.
The first time I started adding tin, I added waaaaay too much. Just a waste of tin.
I run the pot down to where I need to add a few ingots before I even consider adding more tin.

The lead free solder may say on the lable the percent of tin...I've seen 95 to 97% tin....The rest is usually copper or silver.

I've been adding about 2% tin to my wheel weights and alloying in 100 lb batches so all my ingots that I add to the pot while casting are the proper mix. Seams to be working for me.

I brought some silver solder scraps from work that I used to braze carbide tips onto saws with in my past life. I turned up the thermostat on my Lee pot all the way and dropped them in, and they didn't melt....

I will try less tin this season. I am still pretty new at this. Adding the tin was a good way to produce good boolits with minimal experience.

I got a 25 lb. roll of 60/40 and was wanting to try a duplicate lyman #2 and was wondering if any one would be able to tell approx. how much to use.

You want 2-3% tin in your alloy, anymore is wasted...Buck
