    Got a question for you experts!

    Especially want to hear from the regulars on this one.

    I had purchased 200 rounds of 150 grn lead bullets .308 cal.
    Measured with caliper - actually .309 - not a problem.

    I had originally purchased these for my Marlin 336 - 30/30, but found out after,
    that lead in micro-groove pretty much sucks.

    So... rather than even try, now that I have my 91/30, have the brass,
    What I'd like to do is this...

    Reload them in the 91/30, but lighter, so as to minimize leading.

    Since I'm not gonna be gas-checking these, and they are not gas checked,
    its going to result in them heating up and expanding a little, which is good
    because they should hit the grooves better.

    So since my 91/30 was .310 min, to .314 max bore size... would I be ok
    shooting these lead bullets and not have too much leading going on?

    As for powder on hand...

    I've got about a pound of Accurate 2460, pound of IMR 3031, pound of Reloader 7.

    Will be picking up some Varget very soon, as I found it can handle all the bullet
    weights for the 7.62x54r and also seems to cover all the bullet weights for
    my Marlin 30/30 rounds as well.

    Opinions on whether or not the lead non-gas checked in the 91/30 should be ok?

    Also, if you have done this - got a recipe for a 150 grn FN?
    Planning on 100 yard plinking, local range has 25/50/100 yard marks.

    leading comes from gasses cutting past a lead slug that is too small, gas checks or not.

    Are the bullets lubed? Do you know the hardness?

    Yes, lubed bullets, don't know hardness, but pretty hard.
    Hard to push a fingernail in and cause a dent.

    I don't make my own unfortunately... not wanting to play with lead vapors.


    From manufacturers website:

    All bullets are lubed and sized (and gas-checked where appropriate). Unless otherwise marked, all bullets are lubed using Rooster HVR bullet lube. Bullet hardness is about the same as #2 alloy.


    These are certainly not gas-checked.

    .30 caliber - RCBS 30-150-CM - .309", 150 gr., FN

    Those powders would only seem to be usable for 7.62x54R loads above 1500 fps. Above about 1200 fps I always use a gas check.

    You will need some way to bell your case mouths slightly to insert bullets.

    Much would depend on your barrel whether you can use those bullets at all. Some of the Finnish-modified Mosins have barrels as small as .3085". Most of the Russians run large, and I've never seen one that ran small.

    A few links that might help:
