So I made some hunting alloy

[waco]

Please critique my recipe. I tried to remember what I have heard some of you guys using in the past. I didn't bother doing a search for it. I'm a lazy son of a gun.

I used 50/50 COWW/PURE/+2%Foundry type and water dropped. I was mainly thinking a good 30-30 or 45-70 hunting alloy. I've never used cast bullets for taking game. Am I on the right track?

Your input and suggestions are much welcomed.

I would have left out the foundry type. That alloy will take any velocity/pressure your 30-30 or 45-70 can give. Stay away from hollow points and you should be fine.

No HP molds in use at this time.

Glad I only made one pot full

I'll leave out the FT next batch.

Try your alloy air cooled for 45-70 and see what sort of accuracy you get. It should be good for that.
The 30-30 should be very happy with that alloy. Deer won't be.

Your alloy is still lower in Sb that straight COWW so it should be good no matter what.

2% Sb and anywhere from 2% Sn down to 1/2% Sn is what you want, the Sn percent depending on velocity (less for higher velocity, more for lower). Heat treat and age to the speed/pressure of your load. The alloy will work best when pushed near it's accuracy limit, at whatever temper you choose. I.e. @ 2400 fps impact speed it has to be just near max heat treatable hardness to shoot well, and when that tough it takes every bit of that speed to smush when hitting soft tissue. Air cooled, it might max out at 1500 fps, but will mushroom very well at that speed.

OR you can use water-quenched straight WW alloy and use WFN designs. Like anything else, there is an ideal terminal window for armor-piercing WFNs and it takes some time to find it. Different strokes.

Thanks guys!

<<<<------ are 50/50 COWW/1-20 at 1800fps . Impact speed calculated at 1675 fps in damp powdered clay . Start weight was 200-200.1 recovered weight 196.7-198.1 it was a 1 off full spire point launched from an SKS and Paper patched .
Fired in a Savage 06' 100 fps faster in a 1-9 twist ( I know it doesn't exist but 2 tape measures a meter stick and a sheet rock square against 3 marked rods tight patched can't all be liars) it left a quartering away 14" penetration in through about the 7th rib and exiting in front of the off shoulder of rather small 125# mule deer . The resulting wound tract was virtually identical to a 150gr Hornady 3033 SPBT launched at 2690 fps .
Didn't get the bullet back from the deer it took 1 jump about about 20 ft forward and 60 ft down the rise and piled up in a brush heap. Poor shooting on my part as the old white face let the yearling commit suicide . Oh well meat in the pot .
