Depends on WHICH powder, and WHICH bullet. Different powders use different grain weight, and changing bullet weight will also require changing powder weight. Most of the powder manufacturers (such as Alliant, Hogdon, etc) have a website with reloading data for different powders and cartridges. IF YOU ARE RELOADING- please do not accept internet advice for any load that cannot be referred back to a company website. For all you know, I am 10 yrs old, and Mom does not know I am on the computer, and think it would be funny to give you random, dangerous misinformation. (I am not- but you have no way of knowing that)

No, 7.62x39 is different from 308 ( aka 7,62 NATO or 7,62x51 or 308 Winchester ). The 7.62x39 used to be the Russian official cartridge for almost 50 years and is shot by rifles such as Simonov or Kalashnikov. 39 mm. is the lenght of the case and the round normally fits a bullet wighing 168 grains. The 7.62x39 is about 2/3 as potent as 308, developing power level in the range of 1200 - 1600 ft.lbs, while 308 can reach peak powel levels of 2500 ft.lbs Anyways, be sure to never take one of those pills into your back.... potent or not, it could be painful !!!
