    Hello, I am trying to figure out if it is possible to put the .338 ultra mag in a Remington 700 L/A that was originaly a .30/06. Does the ultra mag family have to be used in a longer magnum action or can I just get by changing the bolt head and magazine? Thanks in advance, Adam

    From what I have under stood it is the same action just the bolt face has to be opened up to accept it. Im not sure and I hope some one catches me if Im wrong but you might have to have the feed rails modified to.

    Screech is right, the Ultra Mag actions are the same length as the 06' actions, and you can machine the bolt instead of replacing it. You would probably need feed rail modifications as well if you wished to feed from the magazine.

    Good luck,
    Carl

    Yep, I have a rem 700 in 270 win, 7mm RM, 7mm STW and a 300 RUM rebarreled to 7mm AM and all the actions are the same length.

    Cool, thanks for the replies! Found a good deal on a 700 is why I'm asking. Thanks again!

    The Long Action and Magnum receivers are the same dimension, but adapting a bolt is no simple task.
    I don't expect your project would be too cost effective, Adam.

    You would be better off buying a new bolt than machining a .30-06 .473 head diameter bolt to .534 for a RUM ctg. Remington bolts are hardened, and you would probably need to have the bolt machined for a Sako extractor. Machine shop work is not cheap if it is done right. Many gunsmiths won't do these jobs. Remington will not sell you a new bolt without considerable finagling.

    For about $200 you can probably get a new bolt on Ebay.
    Do you have a barrel? Be leery of buying a used barrel because after only a 4-500 rounds in a magnum chambering, there will be appreciable wear and the barrel is about halfway gone.

    There are shops that manufacture replacement bolts, but they sell a bolt body only and such a bolt would need to have a handle added, and a complete firing pin unit, plus some custom fitting.

    Good luck with your project. You'd probably be better off finding a used Ultra Mag in a gunshop. Lotsa guys trade them in after they experience the recoil. If you are really 16/17 yrs old you have time to save your money. Better to spend an extra hundred or two up front.

    Sometimes gunsmiths botch jobs. Sako extractor-conversion jobs are not as safe as the original Remington design. Better to find a used 338 or 300 RUM, and shoot the sporter barrel out as you get to know the cartridge. You can likely find a good stainless RUM with a scope for $500 or less. Good luck with your project.

    Thanks for the advice, I guess I'll find a factory RUM then rebarrel once I shoot the factory one out. I have made several 3-400 yard shots on deer with my .308, but I'm looking for something a little more challenging. I regularly shoot out to 460 yards, as thats all my range has at this point. I have a neighbor who's got a large field adjoining my range, and I think I have convinced him to let me shoot on it. This should let me get out to about 850-1000 yards. I have found a rifle I think would work, I've always wanted a 7mm STW, here it is. I have a 20MOA base setting around here somewhere that should fit, how does the price look? Thanks again, Adam
