16" AR 15 velocities

Tables like this are good as long as they are used as a rough guide only. You don't know unless you actually chronograph the loads in YOUR gun. I have several rifles in the same chambering, same barrel length, and ammo from the same box never shows the same speed in all guns. It is usually only different by 25-30 fps, but I've seen as much as 130 fps difference between guns of equal barrel length shooting the same ammo. I've seen guns with 20" a barrel shoot the same ammo faster than another gun with a 22" barrel.

i have shot quite a few of both and recorded much of the data with a shooting chrony but all have been handloads with h322 and milsurp bullets from wideners. all from 16" ar's.

if you are interested in handloads data i will dig it up, but im figuring you are wondering about factory loads?
