Learning alloy calculator - GREAT tool but...

[RegisG]

Now that I have some known alloys I've begun learning the alloy calculator tool. It is a LOT more helpful that I imagined. Now I need to find more Sn.

I want to make an alloy for .223 but, I can not search here for ".223". Guess it is too short. LASC gives good pressure/fps for handgun loads but, I didn't see anything for rifle. I would plan on PC'ing and gas check. Can someone help me with good hardness/alloy for 223 or tips on where to find rifle info.

Thanks,
Regis

Yes, 223 does not meet the minimum, but 223 Remington (http://castboolits.gunloads.com/google.php?cx=partner-pub-6216953551359885%3A1942134700&cof=FORID%3A9&ie=ISO-8859-1&q=223+remington&sa.x=0&sa.y=0&siteurl=castboolits.gunloads.com%2Fshowthread.php% 3F283768-Learning-alloy-calculator-GREAT-tool-but&ref=castboolits.gunloads.com%2Fshowthread.php%3F28 3768-Learning-alloy-calculator-GREAT-tool-but%26p%3D3322135&ss=3356j837246j19) does.

If you don't have it, I would highly recommend Lyman's cast bullet handbook. Great resource and generally tells you the alloy that was used to cast the bullets for a given load.

223 for plinking, I personally would cast them from 96/3/1 water dropped from a hot mold. Should BHN around 24 once they settle down. That is about as hard as I can get short of dissolving some copper into the alloy.

for plinking type loads I like the same 1/3/96.
for full speed AR type loads I switch over to 4/6/90 it shoots much tighter groups.
I also use that same alloy for my rcbs 165 silh boolit [which is no speed demon] but does shoot better with the harder alloy.
and switch back to the 1/3/96 for higher velocity [above 2000 fps] 30 cal rifle shooting.

I do have the Lyman Cast bullet Handbook.
Thanks for the .223 tips

Me too. Good information. Straight to the point on what works for alloy.
