How hard is 40/60 solder? This in 40 tin and 60 lead.

Would this be good for rifle? I have Lino I can add.

I’m debating buying some 40/60 or wheels weights in ingots already.

I don't know the hardness but it would be a waste of tin to cast bullets with it straight up. It would be a great way to add some tin to another alloy, like wheel weights. The alloy calculator is a great tool for blending alloy and its in a sticky that can be downloaded.

Lightman is right. Anything that high tin is expensive and will cast light boolits. Before antimony was easily available the highest anyone went with a straight tin/lead alloy was 1:10. Buy a lot of WW ingots and a few solder and you'll be good to go.

2% Sn is the MAX you should ever need!!!!! Why waste your Sn when alloying it is so very easy.

Just use the FREE alloy calculator on here.

You 40/60 will go a long way if used correctly and not wasted downrange.

40/60 is sure different that COWW’s! Do some research B$ you waste your good alloys.

what do you guys think for him, 1/4 lb in 20lbs of c/oww's sound about right?

That would give a BHN of about 11.6

The coww I have used are already right at that number. Wouldn't the addition of more tin to the mix increase the BHN..?

Hes not only adding tin but also pure lead. 60/40 so hes adding more pure than tin. Tin improves flow a lot, added to linotype or mono type it should make a very good alloy. Lino and mono could probably even be cut some with more pure lead and still be very useable

Ahhhhh...right. I was thinking 1/4 lb of tin and not the 1/4 lb of solder.....must learn to not think ahead of what I'm actually reading about....[smilie=p:
