Can anyone recommend a source for 300 BLK brass?
Most likely looking for 1F, but I want all the same headhstamp, not mixed headstamps.

Thanks!

If you can't find any on the EE you'll probably have to make your own from 223 brass. It's actually really easy, plenty of YouTube vids to show you how.
I use a 6 inch chop saw I bought from Princess Auto and just take a few hundred pieces of 223 brass and cut them off at the shoulder, debur them, throw them through the 300BLK sizing die, then a final trim and chamfer and you're ready to go. I like using Remington brass for mine, I've never had any issues with it.
 
X-Reload had a sale on some items awhile back and I picked up some new JBA 300blk brass along with some .308 boolits from them at the time. I'll be converting my own eventually, as CR5 mentioned above, just wanted to start off on the right foot for my first 300blk handloads.

I got a mix of Hornady and Remington 1F, will not sort it but PM me if interested. Half a gallon jug of them

Actually, according to Henry, they are crimped in.

In which case, I can guess the following:
Primed LaKe City 5.56 was cut and formed into 300 BLK so the necks must not be annealed because of the risk of primer detonation. If so, I wouldn't touch that brass.

O.P. - make you own 300 BLK cases. Very easy if you get a "Harbor Freight" cut-off saw. Annealing takes some time but you will have all-matching cases with the ability to make more anytime.
 
I have some 300BLK brass (Rem 223 converted) with 6 or 7 loadings on them and have never annealed them, all still in good condition. No need to anneal from what I've seen so far.

The bags of 300 BLK brass in the picture on the website appear to be annealed to me.

I'm not sure why you wouldn't touch it. I would think that loading it once, crimping the bullet in place & firing it, then swaging the crimps & annealing it if you want, then you have matching headstamp high quality military.223 brass.
