Got me thinking as I finished mixing up some 16:1 today using pewter. It was originally 10.4 BH because of the pewter not being 100% tin. I ended up adding another 6 oz to my 8 pound mix finally getting it to 11BH which I think is what true 16:1 is.
I also use 50% COWW, 50% pure lead, and 2% pewter to the total for my 35 Remington hollow points. It gives me a BH of 10.5.
So if I would have left my 16:1 as is before I added another 6 oz of pewter it basically would have been the same hardness as my 50/50 alloy.
So is there an advantage to one or the other with both being the same Brunel hardness? I’m guessing the 16:1 might be a little more malleable and tougher because of the high tin content? I use these alloys in HPs.
Anybody compare these two alloys against each other for expansion and penetration tests?
