Wait until you see the price I think they will make the mix to your spec,
The price is very high if you plan on selling bullets virgin metal is way too expensive
your bullets will be as pricey as jacketed bullets, Thats why the custom bullet makers all stopped
If you are really that interested in making specific alloys get a large batch of wheel weights melt them down and have a sample analysed by a analytical lab probably cost about $75 -100. Adjust tin with solder.
Antimony is just for hardness but without any tin will foul the bore like you wouldnt believe. There are plenty of alloy mix recipies around and also bullet hardness comparitors but generally a mix of just wheel weights, lead and a bit of solder works for me.
As to testing hardness simplest way is to put 2 bullets nose to nose in a vice if the both mash up the same they're the same hardness.
You need about 9 to 1 mix, SFA wheel weights?
Pewter is my main source of cheap tin. Second hand shops etc. Scrap metal dealers have the occasional printers lead which is high in antimony. To test the hardness of your alloy use pencils as follows. If he pencil will scrape the alloy it is harder.
6B = Pure lead, about 5 BHN
5B
4B
3B = 1in20 tin/lead alloy, age softened, about 10 BHN
2B
B
HB = Lyman no 2 alloy, about 15 BHN
H = Linotype, supposedly about 22 BHN,
2H
3H
4H
I seem to always have at least 3 things in various stages of shipping progress coming from Ali :thumbsup:Quote:

If you repeatedly fail to give pay attention to your wife, she may cast you aside and supply antimatrimony.Quote:

Depends on who you buy it from I pay $13.00 + gst from an engineering supply shop retail is probable double that.
@shooternz is that a 250 gram stick or a 500 gram ?
Found a local source of 99.3% tin solder for $40/kg. Does this sound decent?
195 gram for 50/50Quote:

have you seen the product if it is in ingot form it will be marked to what it is
the price seems to low,
So after Kurt started this post I dug out my supply of solder sticks, but as he now has a supply these are on offer.
I have 10 sticks that are 500 grams each and a couple of the smaller panel beaters / plumbers solder sticks.
From what shooternz says that he pays $13 +gst for a 195 gram stick I reckon that $20 a stick for the 500 gram ones is a fair price.
I will leave it here for those following this thread then list it in the for sale section in a day or so.
Would do $17 ea for the lot plus post.
I'll grab those, legend. Will be down there this weekend, I'll PM you my phone numberQuote:
