Lyman #2 hardness questions

[robroy]

LASC shows Lyman #2 air cooled at 15 BHN. What is it water dropped?

[onondaga]

BHN20-22 is common for water dropping #2. The faster you are and the colder the water is the harder the bullets will be.

I oven heat bullets 350 F. 1 hr and quench in ice water and get a very even BHN22.

Gary , are you heat treating the 5-5-90 #2 ? Reason I ask is that I had the idea that higher tin alloy would not harden as good as 2-6-92 or even the 1-3-94.

[Bob Krack]

It is my opinion that the tin will NOT add to quenched hardness but neither will it prevent the antimony and or antimony/arsenic alloy.

Not sure on the percentages in my alloy. I alloy Wheelweight:Linotype at 7:3 and my Lee hardness tester puts one week old as cast boolits at BHN14 very consistently. That is close enough to Lyman #2 for me.

I'm trying to make 5 lbs of homemade #2 clone out of medical lead and this is what i've come up with:

4lbs 96-3-1 metal
.4 lbs of 50/50 solder (adds 4% SN)
.6 lbs of lino (adds 2% SB)

Does this look right to you guys?

Your recipe will give you:
5.28% Tin, 3.84% Antimony, @ hardness 13.7


If you mix:
0.3 lbs of 50/50 solder
1.2 lbs of linotype
3.5 lbs of isotope lead (1% tin, 3% antimony)

You get:
4.66% Tin, 4.98% Antimony, @ hardness 14.5

7 lbs COWW
3 lbs Lino

1.55% Tin, 5.00% Antimony
@ Hardness = 13.6 according to the rotometals formula. So, it's good to see that the formula matches your testing.
