So I’m building a 223 ackley for plinking and coyotes. I’m having trouble settling on a barrel length. It’s a trued Remington setup with a 7 twist Kreiger sendero. I will probably run a can. Would 24” be a good compromise between maneuverability and velocity, maybe 22”? Y’all have any thoughts?
 
I have a 7 twist 22", Sending 77smk/tmk a little over 3000 fps. My 8 twist 20" 223rem 2850.

I am Going to try a 22" carbon for hunting suppressed. I'll know if I like the length in couple months of use. Good Luck!
 
I'm putting together the exact same thing for the exact same reasons and went with a 26" Proof CF. It'll be suppressed too. Those two activities (plinking/coyote hunting) are best enjoyed in wide open spaces so to me, maneuverability is an after thought at best. The whole reason for going with an Ackley is velocity. Why cut yourself short in that regard?
 
I get 3050 FPS with 75 elds out of my 20”. Could get more but the accuracy and sd/es at 3050 is awesome. Mine has the .061 freebore so I cant seat them very long. My next 223ai will probably be a 22-24” proof Carbon with a longer freebore to run the 88 eld.
