However the MAP for M80 can be from 45,000 to 65,000 psi depending on temperature. The MAP (Maximum Average Pressure) for M59 and M62 is 50,000 psi. The 50K psi figure is not necessarily correct for the 7.62 NATO. 308W loading dies and no 7.62 NATO dies? The answer is because they are the same also need to keep in mind the different working pressures for the 7.65x51 nato and the 308 win, 50K and 62K respectively. Actual cartridge exterior dimensions are the same.
308W based on chamber dimensions (headspace varience gets the biggest attention). Many think there is a difference between the 7.62 NATO and. NO comment as to how suitable a certain firearm is to a certain chambering but I would like to keep at the fore front of our minds that the three rounds are not one in the same.Įxternally the dimensions are the same.
