Too paranoid to say
I was thinking of getting a Mosin carbine and was wondering about the counterbored barrels. I've read that the counterboring was to get more life out of a worn or damaged crown. Would the barrel of a counterbored rifle be more worn than a non bored barrel?

Should this be a consideration when making a purchase?
:confused:

Thanks for replies...
 
If you're considering one of the recently imported refurb M38's, they're all counterbored. The M44's don't seem to be. The bore of the M38's are not necessarily more worn just because they're counterbored.

If you're looking for a shooter, just get the seller to select for bore condition and you should be fine.
 
The last 1/2" or so of the rifling at the muzzle is drilled out larger than the bullet diameter. This is done on a lathe. The point is to create at clean exit from the rifling without having to actually re-crown the barrel which would be more work. If all of the rifles in a batch are being counter-bored is was probably just decided to do it to all of them as a standard rebuild procedure whether a given rifle needed it or not.

Are there any differences between the M38 carbines and the M44 carbines besides the bayonets on the 44's?

The stock is machined for a bayonet groove on the M44 stock and on the M38 the front sight uses a short collar atachment, while the M44 sight base and byonet lug is sleeved over most of the exposed barrel.

Otherwise it's the same rifle.
 
Thank you for the info about the counterboring.

Thinking of it, I read many years ago that new Mosin rifles came counter bored from the factory ?
 
Not so. mosins were never counterbored when new, though the very vast majority of M38 carbines were so altered at refurb. Also as many as half of the M44 which were refurbed also were counterbored.

Counterboring seems rarer on M91/30 rifles though. Some people have guessed that the 91.30's with bad muzzles were used to make the 1891/59 carbines - though that is speculative at this time.
 
I have very little experience shooting the Mosin. Once I borrowed a friends Mosin carbine, and never checked for counterboring, but found this particular rifle to be pleasantly accurate, with military fmj bullets and open sigths. Also, one have to get used to the different safety system of the Mosin.
 
As as I refer to it - keep your finger off the damn trigger till you want to shoot and don't point it anywhere unsafe.

That's the only real safety needed anyhow ;)

And the Mosin's mechanical safety does work, though awkwardly. Also it's tough to make it fail considering either the cocking piece would have to completely crack in half or the firing pin threads shear completely off.

It could be worse too - it could be a carcano safety ;) Or even better - an MAS36!!!
