    What are you asking exactly, the questions a little vague...

    Like KJ, I'm not sure exactly what you want to know, but will try to take a stab at it.

    You must use the same diameter projectile as the original (nominally .308 & .264 respectively) loaded in the exact same cases.

    Or: the bullet weights can be altered, type of bullet may be changed - SP, HP, FMJ.

    *BUT* you cannot change the bullet diameter or use a different cartridge.

    The phrasing of your question suggests you are not particularly conversant with these issues. No biggie, we all started somewhere. But strongly - very strongly - suggest you stick with factory ammo at this point in your program.

    Use only the ammunition that matches the markings of the firearm. If you are unsure of the caliber, consult a gunsmith.

    Remember Ruby Ridge.

    With all due respect to ICONOCLAST, the 7.62 X 54R (Russian) uses a .310 bullet! I'm sure you could get away with .308, but you may lose some accuracy.
    Have fun, be careful!

    The origional spec. for the 7.62x54R calls for a .308 bullet.
    Even if the barrel is oversize (not unusual as I have one here with a .316 bore) the chamber neck area may not allow the usage of larger diameter bullets (neck won't expand enough to release the bullet cleanly). A chamber cast is required inorder to determine if non-spec ammo will be safe.
    You have to remember that the bore and the chamber reamer both have tolerances (you can get a tight bore and a loose chamber or a tight chamber with a loose bore).
    Granted the MN design is a very strong action and can probably handle the over pressure, I've seen a number of pearced primers on factory loads in it.

    Some guys like a mag full of lead, I still prefer one round to the head.

    the [7.62x54] wether ti is nato, russan,chink,or any other name the spec. is the same [7.62mm or .308 dia. projectile] & [54mm in leight] & that is the whole story.the same is true for the [6.5x55]

    Might I suggest that you "mike" some Russian ammo?

    russian ammo I have for the 7.62x54 measures .3105 to .3115, Czech ammo measures .310 Lapua factory measures .3105 S+B factory measures .310

    Why does everyone feel the need to burn that much powder?

    Thank you for an independent voice
    As far as so much powder, I too wonder. If you are out to shoot an elephant, OK, but I (try to) put holes in paper.
    I worry about those in our fraternity who insist on "magnumizing" anything they shoot. Why not just go to a bigger case??
    Have fun, be careful!

    king999, please note I said "nominally" - the original poster seemed rather vague in his request, in my experience the 7.62x54R rounds can vary enormously and so my response was correspondingly conservative.
