View Full Version : Lino/lead alloy...

I have been experimenting with my alloys. I started by mixing 3-1 lead to lino with good results. Because I have limited amounts of lino, I eventually transitioned to a 4-1 mix and got equally good results. My estimates are that is approximately less than 1% tin and a bit over 2% antimony. Sized and lubed I get good accuracy and absolutely zero leading.

It would appear that provided bullets sized to bore and adequate lube, softer than usual alloys can work...

I just acquired a bunch of one lb ingots labeled 10-1 and assuming it is one part tin to 10 parts lead, I am wondering if I should try 2 lbs of lead to one 10-1 or perhaps get away with 3lbs of lead to one 10-1? Will the missing antimony make a huge difference?

i like the 3-1 lino it makes an excellent all around alloy.
the 10-1 cut in half would make 20-1 which is the same bhn as ww's but act's differently.
i have shot quite a few 20-1 alloy boolits and liked it in my revolver cartridges.
cutting it to 30-1 is a popular hollowpoint alloy and is pushed fairly hard with a gas check with good opening of the hollowpoint and excellent weight retention.
for quite some time remington and winchester used 40-1 alloy in thier factory 45 colt and like loads

You will still have as much antimony as the guys that mix their WWs 50/50 .

I guess I will have to give a whirl...

Thanks!

An alloy of 25-1 is my LHP alloy of choice. Cast great, runs to 1250fps w/o any appreciable leading, expands fantasticly.

Fred how do you test your hp alloy ???

If you mean for expansion, wet phone books. The ones around here are pretty decent thickness, about 2" dry. Soak em for 8hrs & duct tape them in stacks of 9"-12". A 12" stack stops most expanding bullets. Expansion in wetpack is sim to expansion in balistic gel & animals, although I recover very few bullets in game.

What type of firearm are you using the 4 to 1 alloy with
I made some up I plan on using it in my rifles 358 win and 30-30 win maybe the kids 35 Whelen as well

the 1% tin and 3% antimony water dropped,
has gone as fast as i could stand in my 358 win i settled on 48.5 grs rl-19 the saeco 250 sized at 358 in my hawkeye. will hold an inch at 100 till i get sore.

in my bolt and lever gun 30-30's i have pushed the same alloy waterdropped beyond jacketed velocity.
i backed down the load so it was comfortably shootable over a day's time.
basically every powder from 2400 through h-414 has done well.

in the 35 whelen i had to send some of those saeco's to blammer to see what they'd do
his rifle shot them well also, but i don't re-call the load details.
he wasn't going slow though.
if you got's the stuff for the 4-1 give it a try and see what you get.

what do you suppose the bhn of that 4 to 1 alloy is
lino is 22 bhn and soft is around 8 bhn
curious as to what the combo might turn out to be

3-1 is right round 12. hits 18 water dropped with normal temps, and tap water.
4-1 i'd guess at 9 maybe 10. water dropped should hit 16 or so.

I would have though the bhn would have been higher than that
but I suppose the lino is cut way down

Can`t remember what site it was on. Lyman #2 alloy was being made with 50/50 Lino/Pure Pb. Anbody try this combo or for that matter ever heard of it?Robert

I use one part lino to 4 parts lead for 40 S&W loaded to major. Lyman to size and lube with hard lube. Pretty much no leading to speak of... I find intact bullets in the dirt berm and flat coins near the steel.

My 3 to 1 WW Lino is bhn 15 air cooled and I get 22-24 oven heat treated, at least that is what my Cabintree hardness tester tells me.

My 3 to 1 WW Lino....

Just to be sure I understand, you are speaking of an alloy that is made from 3 parts WW and 1 part Linotype?
I sometimes read things that are not meant, but I *do* know alloys.
Thanks for your post ... all knowledge is useful.

The 50/50 lino/pure makes " hardball " 2-6-92 which is equal to #2 in hardness. The real #2 would perform better in a hunting rifle.

well fellers it shoots as advertised accurate and no leading in my test gun
model 94 win iron sights with a 170gr.boolit from Tom @ Accurate molds ,
http://img.photobucket.com/albums/v730/kempobb/30-30.jpg,
the load was 33.5 gr w748 lit by a Fed gm215m and the alloy 4-1 ;)
that is a 20 round group with iron sights from 50 yds
oh and 1-44 mag for good measure

That is correct 3WW/1Lino

That's interesting. What velocity were you getting? I would have thought that Rel 19 is a bit slow for this application. I may have to give it a try. Is the Saeco mould you are using the #352? that has been the most accurate CB in my .358 Win Hawkeye when pressing on past 2000 FPS.
