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

Cheers 300cal. Wouldn't foul the suppressor faster or anything? Any advantage going 18 over 16 other than a few fps?

your 2" closer to target.

It'll be a few grams lighter at 16" and therefore less fatiguing to carry that extra 2"

Quite a few of the cullers run 12" to 14" barrels and they shoot a fair amount of animals so 16" be fine.
Mine is 15" or so and have no trouble shooting deer with it. Even out at 300 plus yards seem to die just as dead. I think projectile choice is probably far more important than barrel length to a degree.
My last .223 suppressor was pretty shot out after maybe 1200 rounds. Sometimes 20 rounds may have been fired in a couple of minutes so pretty hard and hot. Zero maintenance. Not bad considering a full length .270 one done between 600 and 800 rounds.
