  1. I like the butt stock, and 20 inch barrel. Barrel length equals speed, speed kills.
    I’m saving my pennies for an M14 however.

    • I was wondering if 20″ might be excessively long for a slower heavy round like .450 Bushmaster. Is that round going to gain much from 20 as opposed to 16 or 18″?

      This does look like a great shorter range hunting rifle thumper. If I get another AR-15 (I have several in 5.56), I think I would like it to be chambered in 6.5 Grendel. It won’t thump quite as well as the .450 at shorter range, but it would do better at extended range.

      • Get an upper and give it a try on one of your current AR’s lowers.

        If you like it, put together a lower for it. If not, sell the upper and move on.

        I’m a fan of 6.5 Grendel myself; be aware that you will need magazines specific to the round, so it’s a small additional expense over and above the upper.

      • 450BM is really pretty efficient in a 16” barrel. With factory ammo, there really isn’t much gain in velocity in longer tubes:

        Rolling your own will help you take more advantage of additional barrel length, or even tame it down, but it can be a bit quirky.

        In terms of big game ballistics and lethality, it’s generally equivalent to a three pellet muzzleloader shooting sabots, plus the benefits of being a cartridge and, in this case, semiautomatic. It’s mostly a niche cartridge, and factory ammo is expensive.

    • possomo…You’ll be saving pennies for awhile. One of my favorite rifles to shoot is a M1A providing it is properly tweaked. Properly tweaked means no slop nowhere. If you get one try to make it look like the rifles seen at the beginning of Gomer Pyle USMC. IMO that is how a M14-M1A should look. For that look you’ll need the more fragile ventilated M14 hand-guard which if desired can be easily match fitted. The M14 forum guys probably can help you locate one.
      Another IMO is go with a standard USGI profile barrel. Use either a gauged USGI, Criterion or Fulton Armory. Even a medium weight MIA barrel such as Douglas can effect handling to the point of asking yourself, Why did I spend time and money to mess up a good thing?

  2. Is 450 Bushmaster the name of the rifle or the chambering? If the name, what is the chambering? If the chambering, what is the name?

      • re: (baby) Hog hammer

        Pushing pennies into a pile for another one. To be fair, not much of a fan of AR patterns on the whole, aside from a piston Blk, because super shorty foldy in the backpack backup carry.

        And then, a -10 platform in .300 Win Mag is an extremely intriguing hog sledgehammer for a couple of reasons.

        1) Win Mag, obviously. ;p
        2) .308 Win recoil, except with Win Mag.
        3) 20 rnd cap in, wait for it… Win Mag

        Negatives:

        1) Price
        2) Damn that sh!t’s expensive for an AR
        3) Feed prices are teh sux for blasting away @ the range

  3. Yes another rifle you can’t buy ammo for. Exactly what we needed.
    Now for Winchester to come along and make and announce a super special round that looks just like Hornady that won’t be on the shelves either.

    • In the states where firearm caliber restrictions are in play 450s are very popular and ammo is plentiful.

    • This. I’m a surplus / common round type.
      Access to .450 Bushmaster ammo post-collapse probably won’t be too good. Government / surplus all the way.

  4. Er, okay. Thanks. Always glad to see more choices on the market.

    That said … I’ve not bought a complete AR in any caliber since I learned how to assemble my own; and this is a caliber I’ve never had a particular interest in. That’s me, though.

    • you beat me to it
      i have 4 bca uppers in 5.56 and 7.62×39
      they all run like a top
      with amazingly good accuracy
      3 inch groups at 300 yards with match ammo in the 5.56
      3 to 4 inch groups at 200 yards with tula in the 7.62×39
      cnc billet upper receivers
      nitrided bolt carrier groups
      enhanced firing pins in the 7.62x39s
      they cant be beat

  7. Hey Guys, i’m making $4000 per month with this awesome home based system, enough for me to make a living.
    You don’t need to invest anything, It’s totally FREE! you just have to download it, here’s the link.

  10. The .450 Bushmaster cartridge typically launches a 250 grain bullet at 2,200 feet-per-second: that generate a LOT of recoil. I have to wonder if that much recoil would tend to cause the aluminum upper and/or lower receiver to fail after a fairly low number of rounds.

    • Yes, it’s not for someone who has a bad shoulder, and it may be tough on a polymer lower, but a decent aluminum lower can handle it. Some guys may adjust the gas or buffer a mite. Accuracy is usually really good, with CD’s results being typical. Anybody interested, there’s some good info & helpful guys at this forum:

      Those guys have been tinkering with this cartridge for years, in ARs, bolt rifles, break actions, and pistols.
