    As a teen I carried this ol gun deer hunting. I remember comments about it being "a .308" which I know its not. My question is what diameter bullet is used for reloading. I inherited a Browning 30.06 and I hope the lead for both is 30 caliber. Thanks.

    Some one correct me if I'm wrong but Mosin bullets are .311 or .312" right? I know for sure it ain't .308 for a Russian model... I think some of the Finnish rifles have a standard .308 bore

    It all depends. Some early Finn models were .308" Some people who reload for Mosin Nagants use .308" bullets for any model. I have found every single one of my Mosin Nagants fire .311"-.312" bullets more accurately (Well except for my Chinese T53, which I have yet to even fire) . I mean its only a 3-4 thousandths of a inch difference. The nice thing is I reload the very same bullets in my Lee Enfield .303 Brits.

    Yeah it ain't much difference, but I'd imagine if a Mosin has a .312 bore it won't shoot .308 bullets very accurately. Best thing the OP can do is slug his bore to see what the diameter is. And when'd you get a T53?

    Speer has some 150 gn bullets in .311. They had some 200gn'rs a while back but are out of production. As has been stated it is best to slug your bore and see what you are working with. I have only found one .308 bullet to work in my MN and it was the Nosler 180gn partition. Under 2 Moa at 100 should put meat in the freezer. Or you can just grab a $9 box of Silver Bear ammo and be good to go.

    Now you did mention lead. If you are casting. You can use the same mold for both the 30-06 and MN. Just don't size them for the MN.

    You should have it checked

    Just to be on the safe side a gunsmith can push a bit of soft metal down the bore. Then the exact measurements can be taken for the lands and the grooves.

    Knowledge and safety must come first. Then reloading performance can be obtained.

    I slugged my barrel, but I damaged my knuckles in the process.

    A .308 will work beautifully in a Finnish barrel, but not so well in a Soviet rifle.
