So, I've been curious how #2 casts. I have some really rich alloy. I had some lead tested and used the alloy calculator to get me close. I mixed up some lead to get #2 and had it tested. It came out Pb = 89.6% SB = 5.7% SN = 4.7% It's pretty close, tin content is lower. It should be good. anyone see any problems?

Shouldn't be any problems with that alloy and it should cast some very good bullets. However, it may be a bit antimony and tin rich for most cast bullet applications unless you are casting for high velocity or match shooting. Even then I would add 10% lead to it. For most cast bullet applications I would cut that alloy with 30 - 40 % lead to reduce the antimony and tin percentages to the 2.5 - 3 % range.

I was thinking 50/50 with pure but I agree 100% with Larry.

It's for a 38 super race gun pushed hard. Like I said, just wanted to see how it casts. I'm usually much lower in sb/sn.

that's pretty close to my 4/6/90 alloy that sees quite a bit of use in stuff like the 223, and for some 30 cal. target work.
repeatability is more useful than an exact 5/5 number.

Only problem I see is you have it and I don't!

Once again...I agree with Larry. And if I had what you have....I'd be in the shed casting boolits right now!!

I like Lyman #2 because I don't foresee a need for anything more than that, and it does cut with plain really well all the way down through 50/50 mix. When I shoot for mixing up a "batch" to have on hand that is what I shoot for. That or some COWW + 2% Sn. Oh and it does cast really nice boolits, even the Lee TL designs :-)

If you wanted to get a little a-retentive you could add .25 lb. of 40% Sn solder and 1 lb. of plain to every 10 lbs. of your 5.7/4.7 alloy and according to the alloy calculator it would put both Sn and Sb at 5.07 so it would be balanced and pretty darn close to 5/5 alloy.
