Hi all, I am new to the forum and a part time caster who is starting to get serious about it. I am looking at getting into oven hardening of various projectiles in .30, .375 & .458 in conjunction with selective softening of noses etc.
All OK up to this point until I look at the humble wheel weight here (Australia). The alloy content is all over the shop and I have no hope of getting consistent results. Only one thing for it and that is to blend my own. This is where it get's a bit interesting, as I need a bit of help as to the best brew to use.
What I think I want/need would be 2.5% Tin, 3.0% Antimony, a trace of arsenic so I can harden and the balance lead. So if I use 1kg (2.2lb) Lino (4/11/85) + 3.0kg Lead + 120 grams (4.4oz) of 50/50 + 500grams (1.1lb) of High Antimony Shot (6%) this will give me a mix of:-
2.49% Tin, 3.03% Antimony, 0.1% Arsenic & the balance lead.
Is this going to work for oven hardening or should I be fiddling with the mix, bearing in mind that I want things tough not brittle and want to bring the noses back fairly soft in some applications.
Any feedback most gratefully received.
Regards
Michael G
