Bagarocks 36 Posted August 16, 2012 I just started handloading 223/556 ammo. Does anyone know if the head stamp "F C" is Military brass? I do have LC brass which I know stands for Lake City which is Military. If anyone can give me some help on this it would be appreciated. Swaging is a whole nother issue I wont even get into right now Quote Share this post Link to post Share on other sites
Krdshrk 3,878 Posted August 16, 2012 FC = Federal Champion - most likely not military brass, but I wouldn't count on it 100%... http://www.ar15.com/forums/t_6_42/253106_.html Quote Share this post Link to post Share on other sites
Old School 611 Posted August 16, 2012 FC = Federal Champion - most likely not military brass, but I wouldn't count on it 100%... http://www.ar15.com/...42/253106_.html IIRC - FC= Federal Cartridge essentially the same thing. BTW I reload this brass and have 2 or 3 loadings on the brass thus far. Now keep in mind I only load 55gr bullets to about 2800 fps which is on the low side. Very accurate load but at 2-300yds a little more parabiolic in tragectory. Quote Share this post Link to post Share on other sites
Bagarocks 36 Posted August 17, 2012 thanx for the replys, That link was a very interesting read some pro's mostly con's Im gonna give em a go and be cautious and suspect. I too am using 55 grain bullets will be using H335. I will be using minus 10% from max load. Do you know if I can reduce One or Two % more??? Wife enjoys shooting her AR with light recoil (arthritis in the shoulders) any help on how far below 10% would be appreciated. Quote Share this post Link to post Share on other sites
NJKen 23 Posted August 17, 2012 Be very careful going below minimum loads. too much free space inside the brass can create a dangerous pressure spike too. going too low on an AR also can cause a case not to seal against the chamber. If the brass comes out all sooted up that means its not sealing well, This happens with NATO brass more than 223 brass. Ken Quote Share this post Link to post Share on other sites

I load this brass with 55 grains bullets, 25 grain H335, and find it to be quite a consistent nice load. I use the CCI #41 primers for it as well.
