Thread: 308 Norma Magnum

  1. #1

    308 Norma Magnum

    Ok I've got an old Mauser 308 barrelled action that I picked up at auction to use to build a nice classic stalking rifle on. The auction house didn't spot this nor did I at the time But its not a 308 win but 308 N MAG.

    The barrel looks quite good whats your thought could this be a nice odd ball stalking rifle, I believe very similar to 300 WM? or will it be a horrible kicky thing, that needs rebarreling?

    within reason it's stock shape and rifle weight that causes recoil to affect you in a bad way , I run a 300rum and its a pussycat but it's really heavy and has a massive moderator or a good brake when I fire it.

    so I say go for the 308 norma mag and enjoy yourself but check on ammo availability before you commit if your not a reloader.
    Right where's those stones , I'll start !

    It's very similar to a 7mm Rem Mag necked up to .308. So it will have a bit less powder and a longer neck than a 300WM. I would definitely give it a go, brass can be ordered from Norma, or factory ammo for that matter, or you can form it from readily available 7RM brass. It has a good reputation for accuracy, I'd suggest looking the round up on, there's a few reviews on there that I know of.

    if you cant find brass for it the best option appears to be sizing 300wm brass which is more readily available

    I run a sporter 300wm that is not much heavier than my .270 Mauser which is light!

    kick is a fit issue but the 308nm is less punchy than the 300wm
    180gr for example sees
    308 NM - 63-67g N160 for 27-2900fps

    whereas I am feeding the 300WM
    69gr for 3000+

    Happy with gun fit and stock shape (it's how I make my living!)

    however some rounds just kick like my 404 Jeffery.

    Meant to add heavy and moderators don't go into classic stalking rifles for me! That's my modern remi style rifles.

    Well it'll kick less than your 404 so can't be that bad.

    Rig her up on a bench, see how she shoots and go from there. It'll only be better with a properly built stock.

    It was ,once , popular on the continent. Countries like Belgium and France had a ban on the 30-06. I've Always heard that 30-06 rifles could be rechamberd to 308 Norma Magnum and so many military 30-06 rifles could be cheap transformed in legal sporting rifles.
    Dumoulin, wich is easely comparable to Rigby, made lots of sporting rifles in 308 Norma Mag. A friend has one and it shoots and kills like a dream.

    Thanks guys sounds interesting ironically my 404 is a dumoulin, however it not a rifle that I shoot much or you ever continplate shooting large strings from.

    Does sound interesting over another 308 win and you have to love a belted case!!!

    If you do, headspace off the shoulder and ignore the belt
