    Barrel locknut

    Hi all,

    I am very new to this forum and I am slowly working my way through the huge amounts of info on this site. All great stuff.
    I do have a quick question though. I own a 112 in 25/06 and am looking at replacing the barrel on it. I spoke to one gunsmith about this who rates the savage action quite highly and would do it for me.
    He did say something that made me start looking for more info about the barrel locking nut. He said that the lock nut is just a gimmick and would chamber and fit the barrel into the action without the nut.
    Has anyone else done this and does anyone else think along the same lines.
    Thanks for any replies.
    BTW I am in Australia too.
    Thank you.

    IMHO, the only problem with chambering the barrel "without" the nut? If you want to swap barrels, it has to be headspaces on a lathe. (back to the gunsmith!!)
    The advantage of the barrel nut and floating bolt head is you can do it yourself. (if you're so inclined)
    Don't like the caliber it's chambered in or want to try something else? Brake the nut loose, swap the pre chambered barrels and bolt head if needed, set the headspace and go shooting. And no waiting till the smith has time.

    I often do my Savage barrels nutless. I prefer them that way for aesthetic reasons and for ease of barrel swapping.
    Once you have nutless barrels setup for your rifle you can swap them around more quickly and with the exact same headspace each time. With the barrel nut you need to use GO/NO-GO gauges every time you do a swap and I'm convinced that the headspace isn't the same every time.

    Both answers so far have good points but my thought is if you want a Remington buy a Remington. The reason for the barrel nut is for ease of replacing your barrel with ones obtained from various places. Buy your buddies barrel this morning and be shooting in 15 minutes, barrel is delivered in evening shoot in the morning all with no gunsmith required.

    One thing about barrel nut guns is there is no dout your headspace is dead On not that you can't get a shouldered barrel dead nuts But I have headspaced a lot of Rifles new and old that the headspace was in the Field range ... But never a savage Hope this helops DD

    Barrel nuts are a gimmick, just like having to torque your wheel lug nuts.
    If ONLY we stayed with the backwards thread so they didn't fall off when driving....

    If you don't want to be able to do the work yourself(or without a lathe) then buy any of the non-nut actions out there.
    If you want the versatility to be able to do things yourself, get an action with some nuts!!!
    I'm a firm believer in the theory that if it bleeds, I can kill it.

    Or better yet, get a lathe!

    Can't imagine not having a lathe now that I've had one in my basement for 15 years.

    You then can have the best of both worlds. Do it yourself ease and nutless aesthetics and headspacing sans gauges. (once your headspace is set initially of course)

    Nutless Savage bbl?..... Why make a silk purse into a sows ear? If you'd rather line your gunsmiths pockets w/ cash go nutless. The "gimmick" is that you no longer need his services !

    Unless of course you want something other than a generic chamber and in particular a generic throat.

    To me a throat cut to my exact desires is the primary reason to go with an aftermarket barrel.

    And even though I often do my own throating and chambering I find great value in gunsmiths who are profitable, talented, and knowledgeable. I see them as an asset to the shooting community rather than a detriment.

    We've trod this ground before and my opinions on this are my own and only provided as one answer to the question raised by the OP.

    I wonder if you can get your tools; action wrench, nut wrench and gauges, as well as your barrel for the cost of what you would pay your smith? Hmmm.

    When I was affluent (translation; working) I lusted after a lathe and a Bridgport. Even used, good ones were outside my ability to pay. For the cost of a good lathe (Hardinge) I could own a passel of very expensive rifles. The barrel nut let me build two rifles for cartridges I love but are not in any makers catalog. .35 Whelen and 7mmMauser. Cheaply and not having to resort to machinery. If you really want a nutless rifle by all means build one but as for me I love my nuts. Aestheticaly I think the barrel nut looks manly and sets us apart from the mundane and usual. (translation; Remington, Ruger, Winchester etc.) Although, I do love Mauser actions.

    The nut/nutless aesthetics are up to you. Your smith is saying that he can turn a shoulder on a barrel, chamber and headspace it to your gun, and you can then remove/replace it to the same headspace without gauges by simply screwing it on and off. While it will work easily on that action, you may not be able to put it on another action and have acceptable headspace. A barrel with a nut can be swapped between guns and set to each by using go/nogo gauges. Loctiting a nut or pinning it are similar ways of maintaining a certain headspace on a barrel. Once the barrel is headspaced to your gun, there is no further need to be paying the smith, and he may set a barrel up this way for the same cost as turning/threading/chambering a barrel with a nut. He's not necessarily just out to get more money from you. He's offered you a viable option that does not limit you. You can still use other barrels with or without nuts or even have the threads turned out later to put a nut on if you wish.

    Personally, I wouldn't have spent a dime more on my old Savage to have a quality smith do anything. Since I can do it myself, Whole new game!
    My first bolt action was a 7mm Mauser 98' sporterized. I killed a lot of deer with that one. I do love the Mauser action, such craftsmanship. I will look for another of these one day, and I'll put a nut on it! In fact, knowing what I do now, I'd nut anything.

    A nut isn't necessary on a Mauser. Neither is a shoulder in fact.

    Mauser barrels screw on until their flat breechface contacts the inner C-ring which is all you need.

    So a nut on a Mauser would be superfluous and wouldn't help you swap barrels or headspace.

    A gunsmith could've told you this.
