.223 AR Velocities - Longer Barrel, lower Velocity?

I tell you this stuff will make you crazy.

I already chrono myself nuts. The Garmin opens tons of more ways to torture myself.

If this is not enough for you, you could always try dealing with the Government!

We chrono'd 6 14.5 barrels against the 16" Colt 6920 gun today some slower, some faster.

Assuming all were chrono’d the same day with the same ammo.

Are the barrels the same twist rate?

I have an 18” Wilson Arms 1/8 .223 Wylde that shoots pretty much the same speed as our 1/7 twist 20” White Oak (Wilson Arms Blank) with a WOA .223 Wylde Chamber. Same Ammo/Same Day.

I think the 18” is just a fast tube….not only is it Fast but also the most accurate ar barrel I have ever owned. Coincidence, maybe.

Side Note: Last year I used it in AR Tactical to win the Oklahoma Mid Range Prone State Championship, the NRA Mid Range Prone National Matches (all 4 matches & National Championship) and my 12 year old shot it in the Texas State Rifle Association (TSRA) Mid Range Prone State Championship matches (for the Win).

Gas port size & location? Same, different?
