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

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.

20" barrel(s) with fairly full house loads and my suppressors (DPT) last about 1000 rounds. Thats pretty much with no maintenance. They are such buggers to get apart.

Cheers gents, I'm looking at a DPT overbarrel on a t3x so minimum barrel length of 16-17" by my workings to clear the stock. Min length of 19" with a Maniatis. Are you running the stainless baffle? Presumably they'll last longer with intermittent cleaning? Other than zeroing probably won't be firing long strings of shots.

DPT say they must be cleaned. But I don't 'cos they soon get welded together by heat. You need to do it right from the start. But I fire up to 200 shots in a day and right from the get go that cooks the baffles tight. Mine don't have the SS baffle.

Cheers, I'll just get one with an ss baffle and it should last years with my planned round count

Im running a suppressed 16" 1'8 twist barrel on a tikka . I only went 16' purely for weight reduction. I do handload. In hindsight however I possibly would have kept and extra couple of inches just to push heavy pills faster. In saying that it is beautifully balanced and shoots like a dream .

Tikka is 18" with a standard DPT this time I have been cleaning it and grease the threads to stop locking up tight.
No need for SS baffle with a .223 unless doing alot of shots in a short time.
If you want it to come right back to the stock get a magnum

Mine was 17.25 to get the mk11 magnum back to the forend on my model 7 it shot darn well the 55 gameking about a touch over 3100 I don’t use the stainless baffles on any of my rifles but I wouldn’t shoot more than 2-3 in a row ever

My 18inch tikka 223 with dpt can has done well over 2500 rounds and can still looking good,
