Bullet Hardness ?

[barnabus]

I have range lead with a BRN of 9 and Wheel Weights with a BRN of12-13 do u guys think this is enough difference between the two to affect accuracy. I’m shooting plain base bullets at velocities at about 1100-1300 FPS in 38-55 and 45-70. Shooting them in a high wall and a sharps using smokeless powders. Thanks

I would keep the bullets cast with either one separate. You may not be able to tell the difference but why chance it. You could even blend the two types of lead to make one alloy.

I personally would mix them together.

+1 on mixing the two.
And you will be fine.:cbpour:

[bmortell]

ya if you mix it would still be very heat treatable like wheelweights so you could water drop or heat treat if you want hard lead. or air cooled for somewhat soft. also id add little bit of tin if neither of them had any added

[trapper9260]

I would mix them also .

Mix it up and you won't have to guess what it is.

[barnabus]

when u say mix it up are u saying make a new alloy by blending the two or shoot the range lead and wheel weight poured bullets together?

Make a new alloy by blending the two, then cast.

I keep mine separate. Range scraps and COWW get mixed 50/50 for my general purpose alloy. You can heat treat that just fine.

Hello, Barnabus. It is a conundrum to mix or not to mix. I would mix the two melts with two-thirds range lead and a third hard lead making the melt slightly harder but...that's just me. I would only size enough cast to get a "feel" for the load and...adjust accordingly. Have a good day. Fireball 57

I have just started this endeavor and have about 85lbs of COWW's on hand. Now with any wheel weight becoming harder to come by I have thought about buying some range lead ingots and mixing 50/50 to extend the WW alloy.

You might even find that straight range lead may fill your need.

I have been seeing more and more posts of people using straight range scrap in pistol bullets.

I have, I feel it maybe too soft for high pressure rounds like 380 ACP and 9MM, but you can heat treat rang scraps.

Works fine for my 357 Mag and low pressure rifle plinkers

For a new caster; K.I.S.S. If you mix the two together 50/50 (9 and 13 BHN) you will get a BHN of 11. Before I got a hardness tester I used "my alloy" which turned out too be 11-12 BHN. I used it in all my handguns successfully (except it was harder to find a non-leading load for my 9mms).

I use only range scrap and powder coat for all my pistol stuff.
