    I was looking at them the other day, and I saw one that was about 8 inches longer then the rest... Would it be more accurate than the other ones? It did not have a bayonette on it either..

    It really depends. When the barrel is too long, it slows down the bullet, so that it doesn't travel as far, or as fast, but for that, it is more accurate.
    It may be a sniper rifle developed for closer-range high-accuracy shooting.

    longer the barrel = higher velocity..

    I thought all M44s had ~20inch barrels. You sure it wasn't an M91/30?

    Longer + no bayo = 91/30.

    CAI is just the importer (Century).

    Same length + no bayo = M38.

    Same length + no bayo + really nice blonde stock = possible 91/59 although I doubt it.

    Not true. Longer barrel means more length for the bullet to travel through, meaning more friction on the bullet, meaning slower velocity. But since there is more barrel, the bullet is being guided more, so it is more accurate

    Well, take into account powder burn. The shorter barreled variants of the Mosin have enormous muzzle flash with surplus ammo. Why? Because they still have some powder left to burn, more than likely for the longer barreled versions. Yes there is more friction on the bullet with a longer barrel, but there is also more barrel to build pressure in, resulting in higher velocities (dependant on powder charge).

    BTW, Hello from another Austinite :)

    I think you are incorrect. Long barrel = time for gases to combust and expand.

    Having too long of a barrel will actually slow down the bullet.

    Well, yeah, at some point there is no more expansion/acceleration to be had :eek3:

    Yes, my calculation did not take the expansion of gases into account.
    But yes, a longer barrel does increase both accuracy and speed, due to the fact that the bullet is forced down the barrel by the gases.
    It only slows a bullet down when the gas has fully expanded, and the bullet is just flying through the barrel on it's own velocity, and the barrel is causing drag, which slows the bullet down.

    That's the trick - useful barrel length taking advantage of expansion with enough energy to continue accelerating the bullet. I understand there are a number of .22LR rifles on the market that would have greater muzzle velocity if the barrels were shorter. But trading a few tens of FPS for greater accuracy may well be worth it for target and light varmint rifles.

    The more powerful rifle cartridges out there could probably see appreciable muzzle velocity gains equipped with with barrels so long as to be unwieldly. AR-15 rifles seem to see useful muzzle velocity gains from 16 to 20 inches as well as 20 to 24 inches. I understand that the M4's 14.5" barrel is sort of a liability when fighting at range because the reliable lethality range of M855/M193 is cut down significantly vs even 16" and 20" barrels.

    ok, on a pistol, an extra 2-3 ipnches will get you more velocity.. but if you put a 6 mile long barrel on it.. the bullet probably wont make it out of the barrel..

    Yeah, and the fact that it will also be more accurate at the same time
