I have been able to get a couple of 8 lbers of 2200 for a good deal. Other than 6.8, anyone have any experience with 2200 and 5.56? From what I have read it seems to do ok with the lighter 5.56 rounds? I have a couple thousand 62 grain pills that I was thinking could be a great plinking/stockpile round if the 2200 works with it?

My reloading app ("Reloading Assistant"), that pools data from various mfrs and handbooks I think, shows 3010 fps with 21.6 grs, 54,881 psi, for Barnes 62 gr TSX-BT. The same app shows AA2300 gives 3100 fps for same bullet at similar pressure, so pretty close. these are MAX charges

The Western Powders reloading guide has an interesting chart on sheets 23 and 24. It lists all the powers across the columns and the rifle cartridges in the rows. One thing you will notice is that AA2200 is among the most versatile powders. Now that Hodgdon owns them, the powders are in their guide, which doesn't have this table.

A couple years ago, I thought about loading up a bunch of 62 gr TBBC pulls I had lying around with a powder that has a fast minimum charge. The idea was to have them be safe without load development, but have as much velocity as I could. I didn't see the project through, but AA2230 (aka Exterminator) had the fastest published starting load I could find. AA2200 is really close. Accuracy wasn't great and I didn't end up loading more than a few, so those bullets are just sitting around. Maybe I'll try them with the 2200 some day.

Good insight! This is kind of along the lines of what I am thinking. I'm not ultra concerned with accuracy and since I have some extra 2200 if I can get an acceptable load I'd be happy with that

Thats probably from a long barrel. I was only getting around 3000 from 23 grains with a 60gr vmax on an 18 inch barrel with a CLE chamber.

I use 21 gr of AA2200 with 60gr vmax. I get a 1.125” group at 100 yds with a red dot. I like it!

The data was for a 24inch barrel.

great to know! Thanks!
Data from Saturday 5-28-22

WC 556 Nato bbl, 11.3 inch, Banish 30 suppressor, and Sig Red Dot:

Hornady brass, WSR primer, col 2.250, and AA2200

Temp 81 degrees

23 gr = 3.0” group at 100 yds (3 shot group)

23.3 gr = 1.625” group at 100 yds (3 shot group)

23.6 gr = 1.5” group at 100 yds (3 shot groups) *** swipes present

23.9 = 2.625” group at 100 yds (3 shot group) ***heavy swipes and blew a primer! Danger!

I used it to push a 34gr HP to over 4,000fps out of a 22” bolt action .223

Accuracy was spotty though. Most groups were well below MOA but there’d be 2 bullet holes touching then a flyer opening up the group to 3/4” or slightly more. My guess is there would have been tighter groupings at lower charges but I was pushing for max velocity on these and wanted to push it to the 4,000fps mark.

A little bit late, but here is the chrono data I promised.

18" ARP 3R, CLE chamber.
Hornady Vmax 60 gr, 23.1 gr of AA2200, CCI 400 primers, 2.260 Coal.

Font Number Document Circle Parallel


For comparison here is some factory ammo
Hornady Frontier 5.56 Nato 68gr BTHP

Font Number Circle Document Parallel


So for me its nice to know AA2200 will work in lean times, but Im going to use something else. Probably CFE 223.

Last data point for me on this subject. Picked up a pound of CFE 223, worked it up to book max with no pressure signs. The results were laser beams!

60gr Vmax with 27.7 gr of CFE 223, CCI 450 primers, Lake City (Hornady Frontier) brass. 2.260 COAL.

Average FPS of 5 shots was 3270! From an 18" ARP 3R barrel.
