.308 vs 7.62 NATO Load data

[DarkStarMedia]

So I have looked at a few reloading manuals and they all list the winchester loads but not the Nato spec loads (lower pressure). Anyone hav leads on a relading manual that has the military Nato load data. Same for the 5.56 Nato, although that is higher pressures. Someone needs to make a Mil-Surp reloading manual....

Hornady's Reloading manual has a chapter on 7.62x51 NATO for the M1A as well as a chapter 5.56 NATO data for the AR-15.

Basically all it really amounts to is back off a grain or so from MAX .308 load data with most powders & bullets.
Which you should be doing anyway.

The 5.56 data takes up heavy bullet match loads where the .223 leaves off.

DO NOT get too caught up in the difference.
A max load is a max load, whether you call it .223 or 5.56, or .308 or 7.62.

Start low on the powder charge, workup, all guns are different, with different chamber. At this link you will see on left of page, 223, 308. good reading. http://www.6mmbr.com/index.html
