Welcome aboard.
Are you wed to that powder? I doubt that RL16 is the power you would want for this cartridge/bullet combination. You would have such a compressed load that it is doubtful that you could even approximate what was required to reach a maximum charge.

Code:
Cartridge : .223 Rem. (SAAMI)
Bullet : .224, 75, Hornady A-MAX 22792
Useable Case Capaci: 23.488 grain H2O = 1.525 cm³
Cartridge O.A.L. L6: 2.260 inch = 57.40 mm
Barrel Length : 24.0 inch = 609.6 mm
Predicted Data for Indicated Charges of the Following Powders.
Matching Maximum Pressure: 54250 psi, or 374 MPa
or a maximum loading ratio or filling of 112 %
These calculations refer to your specified settings in QuickLOAD 'Cartridge Dimensions' window.
C A U T I O N : any load listed can result in a powder charge that falls below minimum suggested
loads or exceeds maximum suggested loads as presented in current handloading manuals. Understand
that all of the listed powders can be unsuitable for the given combination of cartridge, bullet
and gun. Actual load order can vary, depending upon lot-to-lot powder and component variations.

Thanks for the data, I'm not stuck on Re 16 but my buddy is using it in a Tikka Varmint. 24.5 gr of Re16 with 77 SMK, 70 RDF and 75 Berger. He is getting under 0.4 moa, of course no velocities to report. I might try it out in my Tikka and run them over my Labradar.
I have been using 24.5 gr of Varget with a 75 Amax and getting about 0.5 moa at 200 m. Velocity is 2887 with an ES of 19, SD 10.3 in an IVI case with CCI 400 primers. CBTO is 1.922. AOL is 2.278. H2O case capacity is 30.88 if I was measuring it correctly. I have been using a GemPro 250 to weigh my powder as I have a tough time getting the ES down..
I also have some CFE 223 to use and I like it for the 53 gr Vmax and 70 gr RDF as it doesn't take as much room as Varget (even Varget with a drop tube)
Thanks Ed

Before you put too much effort into that Amax load, you should know this bullet is discontinued by Hornady. It is being replaced by the ELD-M available in 75 and 80. I've had outstanding results at 600 yards with this bullet (the ELD) in an AR-15 national match 1:8 Wylde throat. I'm running 24 gr of R15 in Nosler brass, and could probably go a bit warmer, but it punches Xs so I haven't messed with it. My COL is 2.330". Not sure if that will work in your magazine or not.
Reference data 5.56 NATO, use caution if you have a .223 rem chamber rather than NATO or Wylde.
This is a common long-line high power loading, an area where I have some expertise. Some other powders commonly used by HP competitors for 75-80 gr bullets are Viht N140, H4895, AR-Comp, IMR 8028

Thanks for your load data.
I persisted and tried RL16 just because of how temp stable it is. I use it in my 6.5 CM with almost no measurable velocity change from 8F to 0F...
Update
Well I got out to the range with 24.5 gr of RL16 and 75 gr Amax Accuracy was there, under 1/2 moa, but velocity was approx 2550 fps. Compressed load, even with a drop tube.
