Hornady NATO 5.56 load data for 55 gain bullets - 05/03/20 04:05 PM

Can someone tell me the min and max loads, with velocities and PSI, for 55 grain NATO 5.56 from the last couple Hornady manuals?

The IMR Reloading Data Center has 26.0 grs, 3133 fps, 43,300 psi and 27.8 grs, 3329 fps, 51,300 psi for .223 loads. Trying to find out if the Hornady NATO max is different.

Thank you.

I dont have the Hornady 10 but I can give you data from other manuals (Lyman 50, Sierra, etc). Let me know what powders you need data for.

Thank you very much.

Looking at CFE223. Weird that the loads for 55 grs are lower than 60 grs.

I'm specifically looking at CFE223 and AA 2520.

Thank you.

The data shown for the 55 grain bullet is for a monometal bullet.

They tend to produce higher pressure, all else equal, than a cup and core bullet.
