    Postak what is the tightest groups @ 100 yards from chrome lined barrels?

    what is the tightest groups you have seen from chrome lined barrels ?

    now all over the internet you hear about how chrome lined barrels arn't as accurate as stainless , and that may be true but just how much less accurate is a chrome lined barrel?

    here are a few chrome lined barrels i have see shoot very well . now i don't know if they ALL shoot like this (probably not) but the results from these seem to make that accuracy loss of chrome lining look to be very small indeed. these are just some we played with on the bench.

    what is the best you have seen from a chrome lined ar-15?

    You know I've never really given that a second thought before nor had I noticed much difference, but most chrome lined barrels are on military guns you're not generally using for accuracy shooting anyhow. So I wonder if there is actually a ,,Real difference, in accuracy between a chrome and non chromed ones??

    Sounds like a good topic for research. Sounds kinda like comparing stainless to plain steel barrels, which I've never found much difference with,,except break in time,,,and Man, do those stainless barrels take forever to break in, there very hard steel!!! Just like chrome.

    I had a DPMS 308 a few years back that took at least 400 rounds to get any consistency with, and that one had the 22" stainless target bull barrel on it. It shot crazy accurate after that though.

    I'm still working on getting the 308 Mauser target gun I got from Bellson broke in, very slow to break in too. I've only got 150ish or so through it and it still needs more. I does get better each trip though, but I can only shoot a box or so at a time with this screwed up neck, so break-in is taking forever,, plus it's just plain friggin winter here 6 months out of the year and not really a good time to go target shooting right now,, @ -12 this morning when I got up,,it's way to cold for that chit !!!! IMO !

    You gave me some food for thought on this one though j427x, as I've never really compared before. That would be hard to test unless you had a plain steel and chrome lined one from the same manufacturer to compare to each other. With a AR platform, not to big a deal, just change them out, but anything else changing a barrel out to keep all things even,, would take much more time to accomplish with to many other variables coming into play.

    It would be worth trying though, especially for you guys that whip out those AR platforms and have the right tools. You could have 100% quality control to keep things honest and even that way, as opposed to using 2 different guns. Which I don't think would give you a honest comparison.

    So,,,,,

    when ya going to get busy on that one j427x ?

    That's a good ? j. I've never tried measuring the grouping with mine. I do know that when I do my part I don't miss. I will go to the range as soon as it warms up a bit and see what the 14.5" Bushy will do.

    i have seen a couple chrome lined cmv steel barrels do 3/8" @ 100 yards ==to me this is damn good. yea it is a cherry pick with ammo it likes but it kind of goes against the "internet fact" that chrome is inaccurate somehow compared to standard chrome moly.

    i have seen some outstanding barrels from colt, armalite, green mountain and sabre that could get way down below an 1" group that were chromed bore--

    i got a 20" a1 del ton that is unlined and i got a green mountain 20" a2 on the way that is hard chromed. the del-ton is accurate but not crazy accurate but it can do 1" all day long with a good load --maybe a hair under.

    the del-ton is a 1-9" actually 1-8.75" twist the green mounatin is going to be 1-8"

    when the weather breaks off and i got the time i'm going to solid bench both of um @ 100 and see what up--lol

    I've never noticed any difference until I was out past the 250yd mark. I think that for 'minute-of-blue-helmet', SS, chromed, or blue steel doesn't matter.

    for just a regular style shooter?

    havent noticed any difference at all.... but im not a sharpshooter... im just a shooter.


    all the paper work/specs ive found on the "new" chrome lined barrels say they are 1 MOA at 100M's or better.
    say what you mean & mean what you say

    I had a chromed lined 11.5" with a 5.5" welded on flash hider that I got numerous groups of around 1/2" with handloads, on a rest, with a 4-16x scope just for giggles. The scope was huge on that gun which I usually shot with the regular sites or a 3x carry handle scope on it. The ss bull barreled upper I had would print one ragged hole. The ss bull barreled upper I have now is at best a 1/2"-3/4" under the same conditions. I think that barrels are all individuals so there will be some overlapping between the two.

    In target or higher end shooter rifles I believe that button rifled non-chromelined barrels are preferred over any hammer forged chromelined type.
    The builds I have on USA barrels seem to shoot very well and perhaps better than milspec. But as noted there are too many other variables to really compare one rifle to another just on a barrel type. There is a lot of variances other than that factor,
