A general rule of thumb is 25 fps for every inch of barrel length.
Now, that is based on the optimum barrel length for a given cartridge. In the case of the MN, the long barrel may be slightly longer than optimum for the available ammo. But even if it were, you'd only be giving up 250 fps +/- a bit. |

alright, thanks. i was wondering because i've heard that the carbines make big fireballs, indicating that there's still lots of unburnt powder which is wasted by being burned after it leaves the barrel.

im not shure of velocity for a carbine, but the ones's I used to have (will have more soon) used to punch trough everthing we though at them bell housings lawn mowers 6 inch diamater maple and pine trees all kind of stuff so it didn't loose to much power, and the concussion and fire ball were bonus

Generally speaking only about 30% of the power from the burning powder goes to accelerating the bullet, the rest is lost to heat and escapes after the bullet leaves the barrel. |
