.22 Rimfire Lead

[Alstep]

Anyone here know the lead alloy content of .22 rimfire lead?

[Bullshop]

I dont know what the alloy content is but I just bought 700 pounds from a member here and it tested at BHN-9.5 for hardness.

[I'll Make Mine]

My reading suggests it's similar content to swaged lead bullets and jacketed bullet cores: generally around 2% antimony, little or no tin. Significantly softer than wheel weights, but still a little harder than pure.

All the 22 rimfire lead that I have tested with my Lee BHn tester has been right at 6.5 BHn.
That meens that it is NOT pure lead, but an alloy of some kind.
I have checked samples from 3 different batches of about 500 lbs each.
They came out of a indoor range that only allows 22 rim fire.

i make it at about 1.5% antimony.

From the lyman cast bullet handbook !
with almost 100% salvaged 22lr range lead , it will be found advantageous to add about 5% tin by weight for most purposes and 10% tin for hard bullets.

Man, that's a lot of tin.

[jabilli]

.22 bullets are made with a soft alloy, so that the bullet will still obturate while being shot with such low pressures.
Exact composition? You might wanna try contacting a customer support representative from a brand you're curious about. I've tried thrice now trying to load Federal's web page since typing this response- Site wont load. Gluck!

22 lr can vary alot depending on the individual needs of the manufacturer for that specific round. Alot of the newer ones actually have lead/tin/antimony/bismuth in there along with a few other traces of whatnot. It is good bullet alloy, wish I could get about 500lbs of it cheaply.
