223 Barrel life?

I realize barrel life is a difficult thing to predict with the various factors that go into it.

Heat, firing frequency, cleaning schedule, bore material just to name a few.

What's the typical barrel life of a 223 proof SS barrel shooting 80 elds with varget? Not rapid firing .


5k doable holding roughly MOA? 10K?
 
I have around 20,000 on my Armalite AR still shoots .5 moa, it's older AR b4 they moved. What's the concern for shoot it out and get another pipe.

Guys. You're throwing in stats from chromed barrels. That's not applicable to this situation.
There is also a huge range of life based on powder type and load configuration. IMHO, AR comp has good expected barrel life but its a PITA to clean. Varget burns really clean, but not great expected barrel life. VV powders can be all over the place, depending on if you go 540 vs 140 etc.

I think roughly MOA at 5K is doable. Like you said, rate of fire, pressure, powder, and cleaning will play into introducing variables to that estimate.

If you were trying to compete in midrange F-class or PRS, you'd probably notice a drop-off in velocity and/or consistency before that point...but for a fun gun at closer ranges I doubt you'd notice much difference.
 
5-6K if it’s a good barrel and you’re pretty nice to it. 3-4K if you’re not.

There’s a moderator on rokslide running around telling people he’s got a Tikka 223 with over 20K rounds on the factory barrel with no accuracy degradation or velocity loss though 😂
Maybe he's shooting cast lead at 900 fps?

:D
 
My WOA 26" 1/8 twist barrel has 6,845 rounds so far using Tac and loads considered 5.56 level and above the max for 223. I shoot 5 round groups then pause for a couple minutes. Using RMR 69 and 75s.

It still shoots sub MOA. I also watch the barrel and gas port for wear.

Just so everyone is on the same page my specific rig is a origin with a proof prefit comp contour 26" 1/7 twist shooting 80 elds at 2900 with 24.4 varget. Probably 5 rounds per minute average. Depends on how many Prarie dogs are out

You could always back down a grain or so to improve life.

How are those rmr 75s? Good enough for prs style club matches?
