223 Hornady superperformance load data

I don't think you'll ever get load data for this ammo. Seems like they use a proprietary powder blend that is not available to the public.

Just don't load to the max hoping to match velocities. Hand loading is about much more than speed
 
Unless someone has experimented with it on their own, you won't find any data.
Both online and from my 2011 manual, Superformance isn't listed for the .223.

I've been reading up on it quite a bit and its wild the amount of powder they are listing for start and max loads. The pressures listed are much higher than everything except IMR 8208 XBR.
 
I stand corrected. I have not seen this powder in my local stores, but found it online:

I also found an interesting read on the powder performance which essentially indicated that the required charge is less than conventional IMR charges:

Also, you may just need to buy the new Hornady manual to get the data you are requesting (it does contain Superformance load data):

Here is the only load data I found that was published by Hodgdon, but it doesnt have any .223 loads. However, in my experience I have actually e-mailed powder manufacturers asking for load data so that I could use up some powders that I didnt use up for firearms I sold. Alliant just recently sent me load data for RL7 and heavy bullets for my .223. So maybe e-mail them directly.

I tried some in my .223 Edge, and gave up on them. 3" to 4" groups at 200 yards. Black Hills 69g SMK under 1", Hornady 55g V-Max under 2". You might want to try a box for accuracy before thinking about ballistics. Your gun might like them. mine sure didn't. Good luck.

I have read that there are several different blends of superformance powder in use by Hornady. So the one being marketed is not the same as what they using for the .223 53 vmax.
