    Gun, Rem 700 was the obvious first gun choice for years, but now Bergara and Tikka...have made better off the rack options.

    Caliber, apples to alligators. For me 300WM blows 6.5 away due to heavier bullets delivering the payload. But our 6.5's have been fun and CHEAP to shoot acceptable factory ammo. All the Pro's and Cons have been laid out above.

Accuracy usually isn't great, neither is the Xmark trigger. The welded-on bolt handle is ridiculous. The extractor is weak and that's why every R700 clone replaces the extractor with a better design such as Sako-style or M16-style extractors.

    There are so many good factory rifles today that solve these problems and shoot accurately right out of the box: Tikka, Bergara, Ruger RPR, etc. I went with Tikka after finally ditching my last factory Remmy. Whatever caliber you go with, if not getting a spendy custom rifle, I'd consider checking around before getting the Remmy.
    I couldn't have said it any better. When talking factory rifles, even a good Remington 700 is lacking and outdated when objectively compared to a Tikka or Bergara.

    Give the Tikka a hard look. Iím currently building a medium range rifle on a Tikka T3 I picked up for $425. Itís a 243 which Iím considering rebarreling to either a 6.5 or a 308. I put it in a KRG Bravo chassis and put a $10 Elay trigger spring in it which dropped the pull weight to a crisp 1.5 lbs.

    Long range shooters generally figured a barrel was on it's last walk when it passed 500 rounds. The 6.5 should give you a few hundred more.

    The longer the bullet the higher the friction is on top of the lands and if you look them with a good bore scope you will see the tops of the lands looking like dried up mud holes with heat checking which some refer to cracks.

    Had a friend give me a 7MM Rem Mag barrel and I borescoped it for giggles and the throat was not that worn but the tops of the lands were heated THAG.

    He said he could clean it and about the end of a 20 round string it started throwing fliers and this is because the checking (cracks) scrap off bullet jacket material and the more copper that is entrapped on the top of the lands the quicker your ability goes South.

    6.5 CM: 147gr ELD, .351 G7, 2725 FPS. 24" barrel

    300 Win Mag: 230gr Target Hybrid, .368 G7, 2800 FPS. 26" barrel

    Personally, I have the 300 Win Mag with a 1/9 Bartlein barrel and with the 230gr Target Hybrid loaded by Copper Creek I am getting an average velocity of 2880 FPS measured using a LABRADAR chronograph. If you get their 300 Win Mag 230 gr Hornady A-Tip the G7 BC is .414 and velocity is 2770 FPS from a 26" barrel. Muzzle brake is your friend.

    A ďfew hundred moreĒ than 500 and its on the way out for a 6.5? Bullshit.

    Iíve taken various 6.5mm bores well over 2,000 rounds and won competitions time and time again with that kind of wear. I won an F-Class match with a 6.5 barrel with 2200 on it.

    It depends on the cartridge, not the bore. A 6.5-284, yeah you may toast it in 800 or 900. To 6.5x47, .260, etc and youíll double or triple that.

    It isnít the bullet that wears out barrels. Itís the explosion of powder. The more powder being burned, the more pressure. If that pressure spikes in the throat as it usually does, it wears the throat faster.

    Yea, 700 rounds and the barrel is toast-Nope, maybe left out a digit, typo....

    Glad to know you got that round count from your high end guns. Thanks for sharing.

    I read this all the time. But I've never found any of the Rem 700 we've ran/are running to be lacking in any area over anything else. Yes that factory trigger is trash, and we bedded the actions. But after adding a cheek riser and a Nightforce, they've never been a problem.
