The more antimony, the more the alloy will shed in large fragments as impact speed goes up.

But even lino would hold together well at 40 speeds.

Some seriously suspect alloy....

On the average, wheel wieght lead is 95% lead, 2% tin and 3% antimony.
I use nothing harder then WW lead. Some times I will add a bit more tin, to make it flow better, and make it a smidgen harder, and if I want the bullet a bit harder, without altering the alloy, I will water quench.
I've had #2 bullet lead, which is 92% lead, 2% tin 6% antimony,
shot at velocitys over 2000fps, actually explode!


yea, sure, whatever, lets just say you have a lot to learn.

I was just hoped the OP would follow up with what the manufacturer said. Hunting bullets are not suppose to 'shatter'.

Indeed Blammer, if a day goes by that you do not learn something, then that day is wasted. I must admit, in my close to 80 years, I have had some wasted days. However, in my over 60 years of casting, I figure that I do know more then enuff to continue to cast!

Good deal!

Keep on Casting!

Agree. Seems most casters using 92-6-2 call them hard cast. The alloy I get of this mix will test 15 BHN when air cooled. It passes the hammer test.

Most my casting though is done with WWs these days & the ones I mostly get are 12-13 BHN.

I've cast some straight linotype in rifle bullets (150 and 165 gr 30 cal for 30-30 and 30-06 and 8mm 175 gr) and shot them into earthen backdorps at 100 yards (speeds up to 2300 fps [by the book not chronnied]) and then dug them out. Some of them (unless they hit a rock) look like I could load them again.

My experience has been that getting the alloy too hot can cause crystallization and the bullets will shatter and can be crushed into fragments with a pair of pliers. I try to keep my pot at the lowest temp possible to keep the lead molten and fill the molds.

My casting is hardly very technical; I use whatever lead alloys I can acquire locally, usually centered on the lead core from old gill-net lead lines. I add solder when necessary to get uniform fill in my molds, adding high antimony birdshot to add hardness if I need it. I expect good penetration in the spruce logs we find on our beaches for firewood, erring toward lead 'smearing' rather than crumbling or breaking up.



This is a bull I shot today with a 320 Lyman .452 from around 200 yards. The bullet launcher was a Winchester 94 Trapper in 45 Colt. The bullet struck the bull square in the left shovel, punched his chest just aft of the shoulder blade, and exited the right rear hindquarter. Lungs were quite thoroughly stirred in spite of the dowel-like holes in and out.
