Remington 760 .308 barrel life?

    Hey y'all,

    Have a '56 model 760 that I'm hoping to get a lot of enjoyment out of. Don't know how many owners it's had, and it's not in original condition, but after a de-coppering it groups really nicely.

    My question is what the barrel lifespan was intended to be when they were made. Would the useful round count go up to 1500?

    I really don't know what the expected range should be, but would like to make an estimate for how many it might have left in it. Thanks!

    I don't know what the designers ever figured for a useful lifespan of the barrel of a 760, but useful lifespan means different things to different people.

    For some target shooters useful lifespan is really actually used up at 1,500 rounds, or even sooner. But a 760 isn't a benchrest gun or match rifle of any kind. You probably don't shoot 1/2 M.O.A. groups with it now, and won't be pulling your hair out on that day where it's too worn to be able to do so.

    And you probably won't be putting many thousands (or even hundreds!) of rounds through it each year, to be eating up that lifespan in a hurry.

    How long will the barrel be capable of putting .308 bullets into a 2-3" circle at 100 yds (if you're doing your part)? Probably for the rest of your life, and then some.

    Run of the mill .223 Rem. barrels last for around 10,000 rounds or so.

    And .233 Rem is much harder on barrels than .308 Win is ever going to be as the smaller bore and higher velocity kill the throat much faster.

    By the time you shoot out that barrel you'll have run many times the replacement cost in ammo thru the rifle.

    do a serious bench rest test on it to see what kind of grouping it does.

    The numbers I've seen indicate that somewhere around 5000 rounds and accuracy may fall to the point that you'd not be competitive in benchrest competition. For hunting accuracy 2X-4X that many rounds.

    I'd call it MOA as it stands; was a surprise to me as I tried a few ammos the other day.

    I really do intend to put a lot of rounds through it, especially that it performs so well. With 10-rd mags and a quick slide it's serious business.

    10 round mags for a 760? Are they made for the 30-06 too? Who sells them?
  8. Col. Plink

    Triple k sells both.

    You'll never live long enough to wear that barrel out, as long as you take care of it. Like your .308, my rifle is way more accurate that it's "supposed" to be.

    I have a ten-round magazine for my 7600 (made by Eagle) in .30-06, but it makes the rifle too heavy to carry comfortably when hunting, so I stick with factory mags. One of them is stamped '.270 Win,' and feeds perfectly.

    If you are concerned about barrel life, resist the temptation to do "mag dumps" from those ten round magazines. The more heat you generate from rapid fire, the sooner you will see your accuracy depart.

    Like, how fast?

    try this out...

    Basically shoot as fast as you can fire the rifle, dump magazine, insert fresh one, and repeat..... extremely fun but quite useless in reality.

    Your wallet and shoulder will wear out before the barrel does.

    Yes, yes. 2"-3" if you're lucky. It's not a MOA gun.

    Oh, wait...

    Yes, they can be very, very accurate! Just like Marlin's lever guns. Far better than they "should" be for what they are. An inch at 100 yds. won't win any accuracy contests, but is very respectable for a hunting/field rifle.

    If your plans are for a hunting/field use, the 760 will more than meet your accuracy needs for several generations, at least.

    My FIL's 760 in .30-06 was an efficient deer-gitter, but with its best loads it was a 2 MOA proposition. In contrast, my .308 carbine is an honest sub MOA rifle with 150 grain Remington CoreLokts. Since it's a huting rig, I haven't bothered with any load development for it. What it does is plenty good enough.

    And neither of us are worried about barrel life. :)

    A competitive target shooter's .308 barrel might be good for 5000 rounds. Might, I saw one go to pot between 4600 and 4700, the owner said it was shooting well the previous week, but he could not keep them on the target that day.
    An F class shooter has to try for half as big a ten ring. A friend who is pretty good at it changes barrels at 2700.

    Now if you are hunting or in a modest accuracy event like 3 gun, you will see a lot longer service life.

    A rifle was meant to 'last a lifetime' back then. Meaning your kids and grandkids might hunt with it too.

    I will likely inherit my dad's 1980 vintage heavily used model 760 some day, and while the outside isn't close to pristine, she still shoots tight 100 yard 3 shot groups.

    I have lost count of the number of deer, elk and antelope felled to that rifle, not to mention varmints and one Russian boar.

    Most extended mags for those rifles don't work very well, dad bought a couple steel ones that were 'run once and put away.'

    Triple K has the only truly reliable 760 extended mags; recommend them without qualification.
