Christensen Arms: New Calibers for the Ridgeline & Mesa Rifles

Mesa

The Mesa and Ridgeline series of rifles from Christensen Arms are some of their most affordable. Now they are adapting to the rising .28 Nosler and hard-hitting .450 Bushmaster calibers as well. Two niche calibers with very different uses. The .28 Nosler is great for hunting big-game or targets when you need to phone in a long-distance hit. The .450 Bushmaster may never be ideal for a 1,000 yard gong, but it will definitely roll a pig into next week. Now you can have your pick of either caliber in the Mesa or Ridgeline.

The Mesa comes with a Sub-MOA guarantee from the factory in 7 different calibers now.

  • 6.5 Creedmoor | 22″ Barrel | 1:8″ Twist
  • 7mm-08 Rem | 22″ Barrel | 1:9″ Twist
  • 7mm Rem Mag | 24″ Barrel | 1:9″ Twist
  • .28 Nosler | 26″ Barrel | 1:9″ Twist
  • .308 Win | 22″ Barrel | 1:10″ Twist
  • .300 Win Mag | 24″ Barrel | 1:10″ Twist
  • .450 Bushmaster | 20″ Barrel | 1:16″ Left-Hand Twist

MesaWeighing in at a light 6.5 Lbs (Short-Action calibers) to 7.3 Lbs (Long-Action calibers) and having an MSRP of $1,295 makes it very competitive with other light sporting rifles.

The Ridgeline now burgeons to 18 calibers with the same Sub-MOA accuracy guarantee as the Mesa.

RidgelineThe Ridgeline is leaner in regards to weight coming in at 6.3 Lbs (Short-Action calibers) to 6.8 Lbs (Long-Action calibers), but tips the scale in regards to pricing. The Ridgeline has an MSRP of $1,995 to shave those extra ounces off the frame while adding in more premium features.

The .28 Nosler and .450 Bushmaster were added into both the Mesa and Ridgeline due to popular demand and can be ordered through any local Christensen Arms dealer.

The outdoors, fitness and anything related to firearms are my passions. I am a S&W Armorer, Glock Armorer, reloader and am coping with an addiction to classic S&W and Colt revolvers (by buying more revolvers). I’ve been a guest writer for Sierra Bullets and love long walks to the gun range.

    So, I’m looking at the top picture of the guy standing on the river bank and I’m wondering… Why is there a condom hanging from the end of the barrel?

    (Then I finally figure out… that’s a tree in the distant background…)
    {:-)

    • Dougscamo

      You mean to say you don’t do this when you go out hunting?
      Tip: If you don’t fire your rifle when it is raining, the condom is still usable for its stated purpose. 🙂
      Personally, I was wondering if he was shooting fish….

      • Uncle Dave

        Shooting fish… I had to think about that for a second… 🙂

        I had heard about this from WWII and Viet Nam… but not for just a regular hunting day…
        Now, what’s that thing about “keep your powder dry”…? 🙂

        • Dougscamo

          “and don’t go off half-cocked”….yeah, gotcha, good for that too…

      • mookiepook

        It’s still useable if you DO fire it…that’s what riggers’ tape is for.

        • Dougscamo

          Yikes! Ribbed for her….nah….not going there….

          • Tassiebush

            I’m relieved you didn’t go there.
            On a different note I heard about this guy who always had one on his gun. He often had to deal with a lot of cougars at short notice in wet valleys!

          • Dougscamo

            Lucky bastard….

  • Stuki Moi

    About 20 calibers between .22 & .30. Then nada, nothing. Then .45…..

    Why so little love for the Whelen and/or 9.3? Which everyone knows are the bestest big game calibers of them all in accurate boltguns; for all those with intact ear drums and remaining nerve endings left in the shooting shoulder?
