.224 cast?

[44Blam]

Anyone cast for .224? And push them hard?
I want to cast for a 5.56 chambered rifle and want to push them in the high 2000 fps range. Seems like a GC boolit that is PC'd might be able to do it?

I got the RCBS mold for my 223 and I only loose about an 1" at 100 yards. IMR 4198 and CCI primers. Fun to shoot. Over 2000 fps but not high 2000's. I stopped load development at 5 rounds in one hole. Info from Lyman Cast book.

I think that the .22 Cal. # 90451 C225-55-RF is probably the biggest selling 225 caliber mold out there. I am pretty sure many folks push it over 2000 fps with a gas check and powder coat.

That has been the goal of many, not only in the 5.56 cartridge (.223 Rem also) but many other calibers/cartridges as well. Use the search function and you will find a plethora of information.

I have been interested in this mold by NOE : 225-51-SP-BA5 3 cavity PB (225450) Just curious if anyone has had any experience with it. Looks to be a nice bullet profile.

NOE 225-55 @62 gr .
Darrs lube , modified light on Vaseline heavy on STP.
H322
2600+ 1" in a 24" Savage 222 1-12"
2050>< 2.5" in Mossberg barreled 223 16" AR 1-8" nom 3" with factory fmj .
Same results with NIB Axis with 1-8" 1-1.5 with everything fed to date .

Harder alloy than my WD 75-25 WW-1/20+copper would probably give higher velocities . I have a great load so development has stopped until I get a heavy for the fast twist .

I've been doing just what you thought would work. PC and GC to drive over 2000 fps. I did find that .225 worked better than .224. Doing it in a 9" twist.
