223 Cast Bullet Loads

[robg]

Use the Lee mold to ,casts well still trying to get results with true blue but I may give up on it and just use 2400 ,want to get a load to approximate 22mag with better accuracy than my 1022 over 50-100 yards for rabbits.

I just saw a 16" 5.56 barrel offered for $54.99 shipped at (Gun.deals)

Hi all - picking up an old thread - hope that's ok. Is there any way around the fact of inefficient burn on reduced charges?
I have some cast loads that are working pretty well for me, but the unburned powder (A2230) is unpleasant.
I've tried A1680 (there exists old load data for it for 55gr 223) but even the minimum charge (17.5gr) is too much for the boolits, doesn't cycle well, and probably is running at fairly high pressures.

Is it possible to get a light charge to burn more completely?

I've got the same problem with AA2230. Using 21ish grains behind a 62 Grain slick side bullet ( Elvis) from Arsenal and looks like I'm shooting black powder. Problem I have is it cycles just fine and accurate for plinking ammo. So no reason to mess with it.

Glad the Elvis / Arsenal mold is working well for you. It sounds like it's able to handle about one more grain of 2230 than the Lee mold. 21 grain 2230 loads cycle well for me too, but precision is lacking with the Lee grooved mold.

Still wondering if there's any general technique to make light loads burn more fully. I am not greatly experienced in this yet, but where my mind is going is finding a fast and safe way to get the case fill to a higher level. Is there a safe filler that will cause more complete burn or am I wasting my time?
