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

This post is bringing up good memories for me.

I had a 20"

Sold it albeit it was a semi varmint profile barrel.

Next time I went for a 16" as a all-rounder for hunting, 3 gun and yeeting with having a great time.

I found 16 was hands down the most practical.

Using irons ringing steel at 270y was stupidly easy.

The thing for a 223 I think I'd actually be more concerned with would be twist rate.
@Beavis will be able to offer more insight on the subject than I but I found 1 in 8 was a good all-round twist rate.

Hope this info helps
