GUN .308 vs the world

Discussion in 'On Topic' started by Market Garden, Apr 15, 2009.

  1. I really can't think of anything more to do to my AR, and I've got all the pistols I really want, so I'm thinking my next project should be a nice bolt gun. I'll probably look for a used Remy 700 or just a barreled action and build it from there. The biggest question is that of the cartridge. I know that there are lots of great niche cartridges out there, but is there any practical advantage over the .308? Realistically, I'll be punching paper at no more than 600 yards, I don't hunt, and until the S really Hits TF, paper punching is all it will do.

    The advantages I can see of the .308:
    Commonly available
    Great factory ammo available
    Lots of bullet choices
    Lots of load data available

    Discuss.

    .308 is a great bolt gun round, and inside 600 yards it will do just fine at punching paper (and in the unlikely event of needing it for vs. people, it'll do just fine at that too)

    go for it :bigthumb:


    any reason why bolt instead of semi-auto? (AR-10 would be sex)

    I have the recipe for Federal Match ammo-

    42.3 grains of IMR 4064
    Lake City LR brass
    Sierra Matchking 168's
    Federal Primers

    Pretty damn good load

  4. For the price of a nice AR-10 I could do a great bolt gun. I am attracted to the simplicity of a bolt gun too. For long range accuracy work I'd rather have a very simple rifle where I can minimize the number of variables.

    .308's a good round.
    I say build an m1a/m14 though, a nice accurate semi is alot more fun then a bolt.

    I'd love to have a .308 gun! Since you're inside 600yds I see no reason to step up to anything like a .300WinMag. While most people go with the Rem700 or Savage 10FP, another option would be the FN Patrol Bolt Rifles available from CDNN. They seem to be pretty nice.

    And the FN package is more affordable. Already has the optic mount from the factory, and a Hogue overmold on it. Really all you need is some glass and a bipod if you want one.

    Assuming you reload, what's the advantage of the 308 over others, say 243, 260, 280, 7/08, and all their AI derivatives?

    While it may be perceived that I'm a 308 hater, I'm not. It just is what it is, and that simply a 308.

    Personally, I vote 223AI flinging the 75'max.
     
  10. The 223AI is appealing too. Brass and bullets are readily available, and you can shoot regular .223 if you want.

    I'm a fan of the FN if you're on a budget and don't plan on upgrading anything. The Rem700 has a MUCH larger aftermarket following.

    What does AI stand for and what makes 223AI better than 223 or 308? I'm a boltgun cartridge noob.

    There's good info here:
    http://www.6mmbr.com/223Rem.html

    It's about halfway down the page for the section on the AI, but they discuss it throughout the page.

    Cha-ching. Also, brass lives for-fucking-ever and is easily sourced for free from all the tards shooting AR's and leaving it lay around, bullets are cheaper, powder consumption is dick, recoil is dick, and barrel life (which I really don't even honestly put much interest in, other than to make this list look impressive) is forever +1.

    Run the 75'Max at 2800, vs a 175SMK at 2650 and see what you think.
     
  15. Phrozen, I ran a standard .223AI load with the 75gr. A-Max and a standard 168gr SMK .308 load through a ballistics calculator. The .223AI is showing less drop and wind drift out past 800 yards than the .308. Did I do something wrong?

    So I guess the next question is why would you go with .223AI over .308 if .308 has a better BC?
     
  17. Read my post about this one. I couldn't believe the data.

    Wait, so 223AI cases can be made by running .223 through a resizing die?
     
  19. Based on my calculations, even though the .308 has a better BC, the .223AI is giving better external ballistics.

    Got a link to that ballistic calculator? I'd like to play around.
     
  21. You can just shoot regular .223 through the AI barrel and it will fireform your cases.

    I installed the new 3.03 beta firmware on my iPhone this morning, and for some reason it didn't reinstall all my programs. I manually reinstalled them, but I forgot to reinstall my sweet ballistics program, so I was using the above link to make my calculations.

    I don't hype the shit out of it because I own the patent to the reamer, I'll tell you that much.
     
  24. I was actually in disbelief at those numbers. :bowdown: to the AI
