bullet dia of 7.62x54

[gvnwst]

hi.

my friend is selling a mosin nagant, so i started looking into it and found that the bullet dia is not .308, but .311. is this true? is it possible to mresize the cases to .308? i was thinking about a kreiger barrel.
thanks

Slug your bore.

i was thinking about a kreiger barrel.

Putting a $300 + labor Kreiger barrel on a $70 Mossy strikes me as an odd thing to do.

Might as well just get a .311" Kreiger barrel to start with, so you can still shoot old mil-sup ammo in it!

I've seen both .308 and .311 written up. For what it's worth mine is .314.

It's nominally .311, but as mentioned they vary quite a bit. I believe some of the Finn rebuilds used .308 barrels. Slugging the barrel is worthwhile.

Nagant is .311 (or so)
After I size a 7.62x54 brass, including the neck a .308 bullet will almost fall into it.

I've got a 32 Tula that .309 and a 44 (43) M44 that's .312 . . . .I've seen .314 on other guys rifles. FWIW.

Regards,

I sold mine awhile ago, but the barrel was .311". It was one of those 'sniper' rifles with a PU scope on it. I used .303 (British) Sierra Match Kings 174 grain bullets to handload for it. Right diameter and right weight. It shot very well if I took my time. As someone said, when the Finns re-barrelled them they used .308" as the barrel diameter.

i am planning to make a match rifle over time(that is why i want a .308 barrel, for the better bullet choices), plus i want the gunsmithing experiance.
i am planning on a hunting style stock and a polished and deburreed trigger(i heard that they arent that good on these guns)

some of you said to "slug the barrel". what is "slugging"?
thanks

gvnwst, Look at post #2 by K3. Click on the link, its a "how to" on slugging.

Oops, K3 beat me to it.

The Mossy action has many short-comings when it comes to building a custom barreled match rifle on one.

*The trigger is the worlds worst, and can't be helped much.
*The safety is almost as bad as the trigger, and seems almost an after-thought.
*The split-bridge receiver makes mounting a scope or target peep sight on top impossible.
*The multi-part bolt makes them unkind to expensive brass & reloading.

Not trying to throw cold water on your project, but there are many many more suitable actions to start throwing money at on a custom match rifle project.

i only picked the mosin nagant cause it was cheap to buy, a lot cheaper than my custom 7mm wsm remingtom 700. ($3,500) Thanks for the info
