slugged my mosin for reloading

[sixoclockhold]

so is it that low by mistake, or is that all Mosins were at one time .308, and have worn down to an average of .311.

During wartime you get the product out, as long as it isn't dangerous shoot it. Tolerances are pretty lax I would think at these times which is why you should Slug your bore.

Pretty hard to wear out a barrel, takes a lot of rounds. Will most likely show up just past the chamber as that is the area where all hell breaks loose. Improper cleaning can be a factor also or lack there of will mess it up.

You might want to measure your Milsurp bullets and see their diameters. Seeing as you barrel is pretty tight for those, I doubt your going to bring your accuracy up much my reloading. Breathing, Squeeze and reading the wind, mirage, heat of the day, your rest will all be just as if not more important that you changing your load here imo. Milsurp rounds aren't junk, most people in M91/30 are just experiencing a loose Milsurp round and go to hand loads to tighten everything up as their barrel are larger.

Lastly: Any cocktails that people would recommend? I think i would like to stick to the 150g bullet, but I'm game for anything that works for precision. The dies should get here this week, but I have not purchased any components.

Buy a reload manual, crimp your bullets. When I run Speer I don't crimp, but I only chamber 1 at a time. Take it slow and easy, buy a bullet puller, we all make mistakes, when in doubt, don't shoot it, pull it.

Just HOW did you measure that slug? calipers or micrometer?

Soviet M/Ns should be .311, but I've seen everything from .309 up to .317.

Most as new Soviet M/Ns will slug .310-.312

Frankford Arsenal Electronic Dial Calipers.

Check it again, My 42 Izzy measures .314. The bore is not worn, in fact its full of tool marks from quick and dirty (Excuse Me, Precise) manufacture...

where is our Finn Mosin Expert?

That would be FlyinBrian! Good question, where is that Finn Mosin Guru?

[ElvenSoul]

I know Finn Mosins are .308 to .310 when slugged.

[gunboat]

Calipers are not accurate enough, you need a micrometer --

I'm not going to be much help... he said his rifle is an "Izzy" and I don't know anything about those.

[arslin]

Without your prompting, I measured again. I could says it it likely a .310.

The outside of the barrel is like a giant screw withe the machining marks. I almost like that it is built in the darkest days of the war.

So... Still use the 308s?

[Vlad 11]

If it is indeed a .310 groove i wouldn't send .312's down it. So go ahead try some .308's. Be advised that the die you use will need to have a .308 expander ball
