Thread: ideal barrel length for 223, is there a formula?

And you can handload to take account of length.
to some degree, cut a couple of inches off a std barrel, no issues. Take it down to 16-18 and add a suppressor to regain 50FPS.
I'm running 18inch, suppressed and handloads of 2207. Quickload gives me a very high burn rate has been achieve. groups well with 50gr Vmax (12-18mm 5shot group without trying. Fits well across the quad, carries easy.
