Thread: 308 barrel length velocity loss

Is 18 the happy medium for velocity and noise reduction.
I ask this because I'm in the same situation with a 308 and am looking for the best balance and noise control.
Primarily a bush to 350 rifle and I dont plan on reloading for it.

I must confess I have a 14.5 inch barrel 308...purchased at bits, cut old suppressor thread off hence the 1/2....

It shoots 150gr Sako factory inside 1 moa, it is a bit louder but then noise is also based on environment....

I like it but think 18 is the sweet spot
