    I would like to be able to shoot everything from wolf to match w/ the best possible reliability and accuracy. I always clean after every shoot (that's half the fun), but don't want to have to. I'm leaning towards chrome lining right now. To make it clear, the money is not really the issue.

    Buy what you feel comfortable with. For me the standard chrome-moly is good enough. But you may feel that you need the chrome lined barrel so go for it.

    Oh, I just finished the assembly of my Del-Ton kit and fired 120 rounds without any problems. Yes, I just have a standard barrel so that works for me.

    The first M16s had standard barrels. They shot out the leade very quickly on full auto. I believe thats where the "tumbling bullet" thing came from. The worn out barrels would keyhole at 25 yards making perfect sideways holes. First they put in a Stellite insert containing the chamber and about 8 inces or so long. That worked a lot better. About 1971 the fully chrome lined barrel appeared. I like the chrome but it must be applied evenly throughout the bore. If its uneven, accuracy will suffer. I would get a good quality chrome barrel as I hate rust.

    The last inch or so of bbl is what is critical for accuracy, the leade can affect it some but not enough to negate the rest of the rifling in the bbl. The first M16s were made in a 1 in 14" twist rate. This barely stabilized the bullet and they quickly started tumbling once they entered a body. When cold weather testing was done the thicker air revealed that the bullets would tumble and become inaccurate in lower temps. To correct this they went to a 1 in 12" twist rate. This made them more accurate at low temp but also got rid of the rapid tumbling once they entered flesh. The early "ripped him in half" wounding reports turned into "I put 14 little tiny holes through him and he kept coming".

    Never heard of stellite liners in anything but belt fed MGs, AFAIk the chrome plated chamber and bore of the M16 was the first and only fix for the stuck case malfunction.

    FWIW All browning rifles chambered in the WSSM caliburs are chrome lined at the factory. it it to prevent the barrel from burrrning out. they claim over double the barrel life. they did a press release when rummors of the WSSM barrels only lasting under 1000 rounds.

    I have always heard that chrome barrels are not as accurate and you will likely never see one in bench rest or any other accuracy compititon. If there was a way for those guys to extend barrel life with good accuracy they wopuld be doing it. they spend $1000,s on barrrels a year.

    the leade can affect it some but not enough to negate the rest of the rifling in the bbl.
    HMMMMM I agree you will not likely see a worn throat /leade cause a bullet to destabilize and cause key holeing.

    However you will certainly see a a major loss of accuracy from a worn out/burnt out throat. many guys set the barrel back/rechamber several times on a target rifle or varmit rifle before junking the barrel. I have a 22-250 that has lost most of the rifleing for the first several inches and it went from sub 1/2" groups to over 5" groups. the crown and muzzel are still almost perfect.

    Persoanly I would buy a AR in a varmit configuration with a standard barrel. however If i was planning on taking over the world and shooting 30,000 rounds in the jungle out of a military speck 16" lose chamber barrel then chrome would be my choice.

    call Rock river or DPMS and ask if they recomend a chrome barrel in a varmit/target profile I doubt they do.

    DITTO. dont mean I know or heard of everything however.

    The Gun Zone -- A 5.56 X 45mm "Timeline" 1967

    about half way down it talks about a tests on chrom lined v ersus non chrome lined m16 barrrels nonchrome lined lost acceptable accuracy after 1900 rounds shot a 60 per minute the chrome one went 3600 fired a 60-80 rounds per minute.

    ironicaly enough there is talk of testing a a 5.56 machine gun barrel with STELLITE insert in the next paragraph. they all failed do to accuracy problems. iy was a stoner design HMM

    INTERESTING STUFF also tells of a magizine showing dead soldiers with feild striped weapons in there hands. HMMM

    Id like to find the magazine article with the pics af the wounded GI,s and there feild striped weapons. actually no I wouldnt would serve no purpose. the stuff about the disposable mags and guns being sold to other countries was interesting though.

    60 rounds a minute for 3600 rounds is a tourture test if it was done none stop that would be one hot barrel.

    You don't need it, unless you shoot surplus all the time...

    Chrome is your friend on a short barrel. If you were shooting for the X ring in competition I'd say go Stainless or CM.
