Casting bullets
 
Hi can anybody help me I already reload my ammunition but am interested in casting my own bullets can I use the used lead at the range will that lead be ok just to melt down get ride of the scum on top or do I need to add tin .223 and .243 and 30.06 these calibers which I am casting for thanks

22 bullets, black powder bullets, and lead cores from jacketed bullets are too soft without adding tin. Everything else(mostly handgun bullets) are great the way they are found.

Jse- would urge you to do some reading (Cast Bullet Handbook for starters). .223 will not end well. 30-06 can shoot cast bullets very well. .243, maybe. Cast bullets are loaded to a different power level than jacketed bullets.

Tin is used to create even flow from the pot and positive mold fill. Tin is not used to harden lead alloy for that you use antimony. Range lead tends to run the same BHN as WW metal BHN 8-12? You should use a BHN 24 for the .223 with a gas check. In order to get a 24 BHN you will need straight Linotype.

Make sure you measure the bore and run bullets .001+ to bore. In order to push cast bullets over 1,500 fps a gas check is often needed. Use a hard lube like Red Rooster. If you choose to stay under 1,500 fps and use range lead it will work. You may encounter fouled Direct Impengment tubes and gas blocks on AR 15 platforms with cast bullets. Gas piston rifles may also foul and jam with cast lead regardless of the BHN.

I shoot soft lead bullets in my SKS. I have to tear it down and clean the lead out of the entire system quite often. I would not try it in an AR. My SKS was cheap. My AR was not.

Rick good point. What kind of lead are you using in your SKS? It sounds like you may be to improve the SKS loads some what. :)

All of my SKS stuff is wheel weights. I use that for 308 and 30-06 as well. No problems with those. They are both bolt guns. I have even shot pure lead out of bolt guns while using a gas check. I have pushed them way past 1500 fps. I worry about it more in a semi auto because you shoot a lot faster and therefor heat the barrel up more.

nitestalker 10-16-2012 03:03 AM

Yes the barrel heats up expands allows gas to by pass the bullet. This causes gas cutting which leads barrel. Any way I have used Linotype gas checked bullets in the SKS at over 2,000 FPS with no problems. Try some Linotype .:)
