300 blk velocity barrel length.

The Rattler length of 5.5" gives up a considerable amount of energy to the 6.75" and 9" barrels when shooting supersonic rounds. If you were shooting subsonic rounds there's much less velocity difference between the 5.5", 6.75", and 9" barrels. I wouldn't go for the 5" if it were my gun.

Released by Winchester in 1952 (and adopted by NATO in 1954 as the 7.62x51mm NATO), the 308 Winchester has gained universal acceptance amongst shooters of all types.

Something like a 7.5" barrel with an appropriate 7 to 8 inch suppressor would allow for a ...

For 9mm, barrel length greatly affects velocity. If you want to reliably shoot subsonics below the supersonic threshold of 1,125 FPS, you need a barrel measuring just 4" to 5". A longer barrel - say, 9" - will make most loads leave the muzzle at supersonic speeds. ... using one modestly short barrel length. The 300 BLK also provides greater ...
