223 cast pc full house loads

I got a friend into loading and now casting figured i would share his results. First off we are casting using a new arsenal mold no lube grooves and drops at 220 he is powder coating them comes out at 57 grains and sized to 224. First gun tried was a 7.5 inch ar using h335. He started around 19 grains working up to 24 grains, the short barrel wouldn't burn all the powder and caused a ftf wouldn't chamber cause of the unburned powder. I told him just out of curiosity try them in the 16 inch for function he started again with the loads above he ended up with a 1 inch group at 65 yards with 24 grains of powder. I wouldnt have thought the loads would work that good but now we are thinking about the 3006 and pushing them with full loads . He has checked the gun no leading or fouling at all. I figured I would share his results, hope this helps someone out.

Did you leave the tips exposed for expansion purposes? I'll be in the market for a 223 mold once deer season is over this year. I figure it will be a good winter project. How hard are the bullets?

how much twist in the barrels?

1-7 bullets are ww water dropped the tips are left exposed cause he made a plate sits the bullets in there tip down just to powder coat

how does the gas port look, thats where the leading kills. I have not tried cast in my ar's but several people are haveing good luck, just curious if the port stays clean with powdercoated boolits

I have been running pc 22's in my fireball bench guns at 2600 to 2700 fps with very good results and 30-06 at near full house in my 03 with great results. Sized and lubed, no way in the fb,
.

Pretty interesting he is not having any issues with the 1-7 twist at that speed.

Yes, thats pushing it. There are a few other entries with 1:7 twist and ok performance but they are the rarer ones. Isnt 24gn of H335 pushing a normal load? Thats even more impressive.


I added it to the database thread btw

There are several entries in that thread that have not been put into the picture though yet, including this one.

Am I right that entry no 15 is the same mold? Seems to be a much heavier boolit though so I guess not.

Also did you have to use the NOE expander die?

He is using a lyman expander die set for .224 the only reason his boolit is dropping light is because he asked for the boolit to drop at .220 so we didn't have to size it before coating it. He was trying this out of a 7.5 inch but couldn't get a constant powder burn lots of unburned powder causing ftf locking the gun up so them tried it out of a carbine just to see what kind of accuracy he would get. I am going by there with a 10.5 inch and another with a better scope on it to try the 100 yard mark. I will post back after seeing how it does there. I was loading hndy jwords at 24.5 and 25.3 is max load so yes thats near max load, i wish we had a chronograph, also he hasn't done anything yet for accuracy thats just starting out he had started lower charge weight but in the 7.5. After that never worked he tried the other rifle and got these results. Looks like it has great potential so much so we are looking at getting one for the 308 3006.
