Just about everybody with a AR-5.56 has the shortest barrel with the compensator/flash hider that gives 2 more inches to be BATF legal. Whats that leave you, an effective barrel of what? 14 inches???
I was at the range with my chrono and the guy next to me had one of the AR that I am describing. I was having a hard time understanding why my muzzleloader was chronographing at 2400fps. After several shots and misunderstanding, I figured out that my chrono was picking up the shots of the AR next to me. All 2400fps of it. Do the math.
If you lose 100fps per inch of barrel, and if .223 is good for 3000fps on a 24inch barrel, and most guys have a mere 14" barrel, then yeah, a proper .22 Hornet with a sporter barrel will throw 55gr at higher speed.
Nowadays I call them things Hornet rifles.
