    18inch 308 barrel advice

    Hi guys and girls I have been given a parker hale in 243 it is shot out so I'm thinking as it's a nice mauser action clean it up and rebarrel in 308 but im after a 18inch barrel. So what's a good barrel and twist rate to go for?? This is my first solo build so please be nice. Ant tip and hint appreciated

    Thanks in advance

    Recon it depends on what you want to use it for. I stumbled accross a Med. Palma Bartlein Barrel which has a tight bore and had that fitted to a remington at 20". Mine has a 13 twist which I thought at first wasn't great however she seems to shoot 168gr very well out to 960yds which was my furthest.
    If you don't want to go over 168gr then 1/13 would do but 1/12 will give a bit more reserves. Overall the 1/10 twist might be the best choice and can take any bullet up to 200gr. In the last two three years Lothar Walther 308 Barrels seem to have been of excellent Quality according to precision rifle builders in Germany that I talked to. Profile 1400 would be sporter weight, 1450 would be a medium weight and possible a great allround choice.

    Have a chat to Mike Norris of Brock&Norris, they have been building 18" 308's for quite a while and seem to know what they are doing.

    Suggest 10 twist - that will shoot 150 - 165's very well.

    Lothar barrels are very good , the polygonal rifling seems to be very effective with minimal cleaning reported from the last few I've built.

    If you're keeping the PH woodwork, id recommend looking at the mauser profiles they do.

    Go 7-08

    the kiwi's have been using them out for a few years now at 16". I've shot one for about 6 years at 18.5. Picked up a 20'' .308 and the 7mm kicks it's ass. My point and shoot rifle will always be a 7-08.

    With a short barrel, you are not going to get top velocity from a really heavy bullet, so are you going to be using them? Not likely. Are you going to play at longer ranges? The 155-gr Palma bullets will give you velocity, and are made for 1:12 twist. So to with that. The standard .308 with 1:12 twist will shoot 125-gr to 175-gr really well, and not bad with the heavier bullets it you have enough barrel to get the MV up ( and the spin RPMs).

    Southern what I'm thinking is a max range of around 600 for range days not very often but a very good hill and woodland stalking come fox rifle maybe some boar by moonlight. As this is my first self build I want something a little diffrent and practical. Bullets around the 150 mark I'm awaiting the response on a 1in 10 twist from Bergara barrels hopefully I will know by Thursday

    I've run a 20'' 308 for years , it's fab

    the 308 is a great short barrel round , DTA and RPA make 16'' guns and they shoot very well.

    1-10 to 1-12 will suit you , my 1-12 shot the 168amax very well and the 110 vmax was awesome , you are defo on the right course for a good useable rifle!
    Right where's those stones , I'll start !
