    Ok, so you load.308 differently than 7.62 but do you use the same dies and oal?

    Same dies.

    OK, so here's what I'm wondering...For some reason I get the impressing that the powder cavity is bigger on one than it is the other but the outer dimensions almost have to be the same. This could only be achieved with a thicker wall (I know, I should get my tools out and measure them). If that's the case, wouldn't neck sizing be an issue the way that bell goes through the neck while it's held in the die?

    It is a thicker wall (in the powder area). The external dimensions and the neck neck thickness have to the same. technically military brass has less capacity than commercial cases but in reality the difference in powder charge is usually less than developing a load for different rifles with different freebores.

    if anyone can post actual proof of a .223 chamber failing on a 5.56 round i would be immensely appreciative
    I have spent litterally days searching and found nada.
    From what i can tell from this research is SAAMI and NATO measure chamber pressures at different points and this is the reason for the Eggspurts telling you not to do it. Basically comparing apples to banannas

    The only malfunction that I have heard of is 5.56 brass getting stuck in the.223 chamber.

    The brass headstamp does not matter when reloading. You can use 5.56 brass to load .223 Rem, just load it to .223 specs.

    The only real difference is the powder charge applied to the case. You're not going to pop a .223 case loading it with 5.56 data or vice versa. Some say the case volume is slightly smaller in NATO cases, but I've never noticed any significant difference.

    I seem to recall reading that, 5.56 and 7.62 NATO cases CAN BE a bit on the thick side due to the fact that it MIGHT BE linked for machine gun use. Or was that commercial cases are on the thin side?

    This was even a valid point in surplus 30-06 ammo and USGI cases did normally weigh more than commercial. Lots of the grand old gun writers and wildcatters pointed this out often. Thicker brass , less capacity , possibility of high pressure.

    Would have to see official NATO and SAAMI specifications/drawings side by side.
