What's the recommended barrel length on AR for hunting?

[jmra]

Here is my take on hogs and deer with the 223, AR-15 or bolt platform.

Keep velocity around 2700 to 2800 FPS

Use a 60 gr or greater bullet (Hint Nosler 64 gr bonded bullet)

Keep range less than 200 yds

16" BBL will easily achieve this

Aim straight and have some fun!

Have you considered a 16" Barrel in .300AAC Blackout?

As long as your shots are going to be inside 200 yards, the heavier bullet (with the same size cartridge as .223) may give you more leeway in terms of shot placement. I believe that the vitals on hogs tend to be screened somewhat by the shoulder - so the .300 might be a good idea.

Yes, but he wanted a 5.56
