Cartridges:
 308 Winchester and 7.62 NATO centerfire rifle cartridges are also known as their metric nomenclature 7.62x51mm. Both of which are .30" caliber, rimless, bottleneck centerfire rifle cartridge case designs that are reloadable with various combinations of primer, powder and .308" diameter bullets. 7.62 NATO cartridges are normally loaded to slightly lower chamber pressure levels for semi-auto and full-auto rifle usage.
7.62 NATO Maximum Average Pressure - 60,200 PSI.
308 Winchester Maximum Average Pressure - 62,000 PSI.

Reloading Safety:
 7.62 NATO cartridge casings are usually thicker in the web area, thereby reducing cartridge case volume. Only use published reloading data where this is taken into consideration when reloading 7.62 NATO cartridge cases. Otherwise you will experience much higher chamber pressures and possibly exceed your rifles limitation.

308 Winchester Reloading Data:

 Handloaders have ample choices for loading their favorite bullet weights for many different tasks. From zombie slayers to woodchuck busters, lightweight bullets of 110 grain to 125 grain do quite well and probably better than most people know.

 For the deer, elk or moose hunter hand-loading or reloading his or her own 308 Winchester ammunition, 150 grain bullets will work fine. For larger animals 165 grain bullets will deliver good energy and deep penetration further down-range.

 Handloaders of 308 Winchester cartridges have a couple good choices for loading heavier bullets that penetrate quite deep when used on large animals, 180 grain bullets can normally be driven fast enough to make it worth loading them for stopping power.
