I would suggest the following.
Lapua or Hornady Brass and Rem 7.5 primers. Velocitiy listed for 20" LW barrel.
120 gr. Nosler Ballistic Tip Overall Cartridge length = 2.225
XBR 8208
28.0 gr 2515fps,
100 gr. Nosler Ballistic Tip Overall Cartridge length = 2.225
XBR 8208
30.0 gr 2760 fps, SD 12.2, ES. 30.6
Or if you like ball powder
H335
30.0 gr 2775 fps
These have worked great for me, but I have less range time with the 120 gr load. I saw you suggested 28.5 gr of 8208 for the 123 Amax, and that load would like do well with the 120 NBT as well. I settled on 28 gr to try to lower the operating stress a little.

I wonder what the muzzle velocity difference might be between using 28.5 grains versus 28 of 8202... I am also contemplating trying to stay at the lower stress levels. Does anybody know? I have an 18 inch Satern barrel.... Thanks
