antimony

[periculumnexnecis]

So i mixed 4.5 lbs of ww, 4.5 lbs of linotype + 2 oz of tin.Should have 3.5 % tin, 7 % linotype rest is lead.

I casted 50 bullets and quenched them.I also casted 50 that i planned to heat treat, waiting for my sizer.

Nice and shiny bullets, the one i quenched seems to be real hard.

For lubrication,i was planning to use a mixture of 50/50 lithium grease and bees wax + 10 % parafin.Pan luning.


Better idea ???

Mixing 50%w-w with 50% linotype and quenching it for shooting 30-30 win will make the bullets way over 35HB (and brittle like glass) with waste linotype on top.
Your alloy has more than 8% Antimony way more than needed even without heat threading.
With quenching w-w alone you can get 20HB easy or 2HB more than your target.

So, you are suggesting to forget the linotype, just use wheel weights and quench.

I was under the impression that they needed to be real hard to be pushed close to 2000 fps.

So confusing...

I have Ballard rifled Marlin 336 in 35 Rem with 2x scout scope.
My recipie is 3lbs of clip on w-w +1lb of linotype + 2oz of 50/50 solder.
All together the alloy has about 92% lead, 5% antimony, 3% tin and 15-17 BHN.
It's a little "cheaper" alloy than famous Lyman #2 one with 5% Antimony and 5% tin.
Perfect for me b/c bullets are not to soft and not to brittle and expand in deer just right.
I shoot 190gr RD bullets with Hornady GC at 2000fps with no leading and great accuracy.

I will give it a try, should be good for me too, what do you use for lube.

If you use w-w quenched by all means use at least 2% tin.
I use double coat of thinned (adding some laquer thinner) Lee lube once before sizing and once after.

Tank you so much to share your experiences and know how.
