308 Winchester Reloading Data Chart

March 10, 2019 By GunnersDen

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.

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.

    I shoot a Winchester Model 88, 308 I have been loading 165 grain nosler ballistic tip with Winchester 748 powder. I just purchased a pound of win 748 and unfortunately gave my data books away and thought I could find all the loading and ballistic data on line. So far I have been unable to find what I need. Can you point me in the right direction?

      Hey Jack, there isn’t much out there and that combination has been mostly removed from the modern books and reloading data. Not that it won’t work, because as you know, it does.

      Here is a PDF of an old reloading data book from Hodgden. https://2amusing.files.wordpress.com/2008/12/hodgdon-basic-manual.pdf

      I hope this helps a bit, but there isn’t much out there unless you get those old books back.

      Thank you for the question,

      Josh
