Yes, 36 is the bhn number I have seen in pretty much all of the alloy calculators I have come across also and in testing the actual alloys it holds pretty true as far as I have seen.

Worry less about BHN and more about the percentages.
The alloy composition is fixed, BHn can be manipulated.

and a BHN point here or there is meaningless.
10-11 11-12 whatever,,, your gun will never know the difference.
12 and 16,, then things will show up, but you've gone from 3-4% antimony to 5-6% antimony at that point.

My "soft" is salvaged off a RF only range. So will be high 90% LR STD VEL. SOME HV some 17/22 mag and maybe the idiot shooting CF against the rules. I did see three jackets when smelting.
I do not ifficially know but I am assuming its real soft with MAYBE some tin.

My plan was lino to harden but a friend has gifted me SuperHard for the purpose. I know SH is harder the. Lino Substantially less then SH. Was gonna do 3:1 with lino.

Maybe 5:1 is better....

Seeking 12 ish BHN. I dont "need" that its only a target.

THANK YOU, as always you guys ROCK!!
