NO.2 babbit tin

[lastborn]

I have some of this.

Anybody ever use this in there alloy? What would be a good use of it in boolit alloy? I cast .38/.357 plain base and checked----45 colt plain base---.35 rem. ranch dog---460425 ranch dog--- NOE 460350 checked--- and several 30/30 from soup can to 173 gr checked. So what would be the best use of it?
Thought about trading it off cause all I ever use is straight COWW with a little added tin or 50/50 PB-COWW + tin and don't really see the need for anything else. So what you think?

I would use it with the coww, bringing the tin up 2% myself. I haven't run the numbers, but don't think at that rate, the copper would create issues.

That little bit of Cu will add quite a bit of toughness to your alloy. Hard, but not brittle. Just consider it a bar of Sn and add it to your alloy in the same proportions you do your tin. Then take that 35 Ranch dog out and compare your old alloy and your new using that great scientific testing device, a big hammer. You'll be surprised at the difference, I was.

Although not nickel bearing, I have mixed a 5 pound bar of the number 7 babbitt with 100 pounds of soft lead and it has produced an excellent boolit for my .38 special. I guess it pretty darn close to 20:1.

If you use that babbit bar at the rate of WW's+2% tin ("tin" being the babbit bar metal) the other metals percentage is too minor to count. Just think of it as pure tin and you'll do fine at the 2% range.
