Archived [ARCHIVED THREAD] - 6.8mm SPC: Effect of barrel lengths 16, 18, 20 & 24 on velocity and accuracy
Posted: 9/20/2004 9:09:37 AM EDT
Anyone have any comments on the differences in accuracy and velocity b/t a 18" bbl, a 20" bbl and a 24" bbl?

IIRC, Zak already addressed this issue somewhere around page 7 or 8 over here:

I didn't see it in the FAQ.  I'll look again.

Sorry, it wasn't in the FAQ, but it's in that thread somewhere.    Here's what I've heard, for factory ammo.  Expect to lose about 150fps from 18" to 16".   18" to 20" will not gain as much.
