Pushing the 250 FTX with 38gr Lil Gun, every inch of barrel length is approximately 25fps. The 20" barrel such as i use in my AR platform will net you 100fps additional velocity over a 16" barrel. I'm not a pipsqueak and toting around a 20" barrel doesn't pose much of a deal breaker for me. Truth be told, the 2" brake actually makes it like toting around a 22" rig. Most of my hunting rifles are 24 or 26" so I'm kinda used to it. Getting the muzzle blast 4 inches further away from you is also a benefit. To a lesser degree, the additional length reduces the recoil some as well. I just find it a smoother experience overall with the 20" over the 16" but that's just me.

In Theory, there is no difference between theory and practice. In Practice, there is.
