So my best loads were;
15.0 grs IMR-4227 16.0 grs 2400 16.0 grs H-4198 21.0 grs IMR-4895 22.0 grs IMR-4320 eta, a link to a 223 cast bullet thread from 2014. http://www.ar15.com/forums/t_6_42/425608_A-guide-to-casting-for-the-AR-15.html |

Thanks dryflash3. I haven't had any real success. I shoot at 50 yards with a 16x scope.
I got frustrated and quit messing with them but with your report I may go try some more. What gas checks are you using? I'm using aluminum at the correct thickness. For some reason I haven't been able to pinpoint yet aluminum gas checks do not work on my 30 caliber bullets (7.5x54 MAS) but Hornady copper ones work great. This is speaking accuracy wise only. Either do the actual gas checking well it's just the aluminum ones result in very poor accuracy. Also. I have some old stock H-4227. Does anyone know how close it is to the current IMR-4227? Motor |

If your having issues with al gas checks that's telling you that they are too hard/need annealed. When a gc falls off you will get fliers from that bullet, doesn't matter the caliber. Take a small piece of pipe that is threaded on both ends. Tighten a cap on 1 end and put some gc's in the pipe and a small 1" square piece of paper in the pipe with the gc's. Put a cap on the other end of the pipe and tighten it. You want an air tight seal. Put the pipe/gc's in a fire and anneal the gc's, let them cool and open the pipe and dump your annealed gc's out. The now soft al gc's will stay on the bullets just like the soft copper gc's.
I looked at casting bullets for the ar's years ago. Came to the conclusion it can be done but it's a real fine line with what works and what doesn't. Between the fast twists and having to cycle the action more goes wrong than goes right. If I were to take the cast bullet/ar combo seriously I'd: Use a 1 in 12 twist bbl A dedicated lower/rifle with a modified buffer and buffer spring 65gr to 70gr bullet At least lyman #2 alloy size the bullet to .226" Good luck, it's a up hill battle but I'm sure you have the talent to find a load/combo that works for you. |

I just throw the charges on my Harrell's Precision and go shoot. This is a maximum load (3177 fps from my Winchester M70) in spite of being close to 1.0 whole grain below most of my data sources. This powder teamed with these light bullets is amazing on target. 1/2" ten shot groups on occasion, almost always under an inch. It's very course, it looks like long sticks of mechanical pencil lead. It crunches all the time when thrown, but it doesn't effect accuracy. |

It's kinda on the back burner for the time being but I'm hoping Hornady copper checks solves the accuracy issues. I was getting an occasional 4-6 shot string to come in under 2" at 50 yards but typically the groups are 3 to 4 inches. I have had issues with aluminum checks in 30 caliber so hopefully the copper checks will work for the 22 caliber too. Motor |

That's a couple of advantages with powder coating over plain lube,
1) Diameter of the bullet is less critical 2) Lead alloy is less critical My bullets alloy is range lead, unknown bricks of lead a friend gave me, and wheel weights mixed together. I think clean alloy made the most difference for me. I flux with sawdust. Why is in the book I linked to earlier in the thread. Fluxing chapter. I don't water quench either, waste of time for me. |

I don't think I'd quench them either. The only caliber that makes me want to quench PC cast is 357 SIG. I have concerns about unquenched bullets riveting below the neck, so my SIG will get hardened bullets to hopefully avoid something that may not happen anyway
