  1. Excellent Buy!!!

    By Shoots with any custom gun. October 25, 2018

    I purchased my Lapua in 2015 and have shot next to all the big Long Range gun names. I have never walked away feeling disappointed in my Weatherby. Shooting a 300 grain Berger 2,900 fps with a ton of knock down power. This gun has put multiple animals down with one shot in excess of 1,000 yards. Super accurate and consistent to 1,760 yds. Loved it so much I bought the 338-378 in the same platform. Love both guns. Great product.

  2. Great Gun, well hopefully soon.

    By GTC April 28, 2018

    I purchased a couple of years ago and just now getting around to shooting it. Put a March 8-80x56 scope on top in case I need to keep my distance. Love the feel, balance and after adjustment the trigger is sharp.

    As to the performance, haven't been able to find the right load. MRP, H1000, Retumbo, RL33, 25, 22, and H4831SSC combined with Berger 250gr and 300, 265gr LR Accubond, 285gr Hornady Match, 300gr Lapua Scenar, over 100 different loads, all taken from reloading manuals, but I can't get 3 shots to group tighter than 1" at 100 yards. Read to sight in at 200 yards to let the bullet settle down but no luck. Used recommended OAL and tried different seating depths. I hope I'll find the right load but at the rate I'm going I'll shoot the barrel out before I find the one. Been reloading for 30 years and this has been by far the toughest gun to figure out. Reputation states the gun will shoot but once in a while you get one that won't. I hope that's not the case because time and money keeps adding up.
    Any load recommendations will be more than appreciated. If you find me the right one, I'll buy you a worthwhile Christmas present!

  3. Great rifle for the money

    By Defiance March 20, 2018

    I bought the rifle in 2013 and immediately fell in love with it. It is extremely accurate and very comfortable to shoot for a big caliber rifle.
    It does get a bit heavy after the third or fourth day of hard hunting but you would expect that out of a big rifle toppped with a nightforce 5-25 by 50.
    With 99 grains of RL 33 and the 285 grain eld match bullet it puts two out three in the same hole at 100 yards doesn't get much better than that!
    Shot my last two bull elk at 419 and 437 both one shot killls and shot it out to a mile on steel great rifle!! Thanks weatherby!!!

  4. Great rifle

    By Noveske November 30, 2017

    I purchased this rifle late 2016, rifle came at a fairly fast pace, didn’t want it sitting in the cold too long, being it’s a blued barrel. When I got the rifle, I had some surface rust on the barrel, a days cleaning did well, I can’t seem to keep surface rust off the rifle, I clean every other month and always get a brown residue, the rifle is very accurate, and have had no problems. Only use Lapua brass, 250-300 grains, will start reloading when time allows.

  5. Comfortable accurate rifle in .338 Lapua

    By Shirt February 17, 2017

    I bought the Mark V Accumark 338 Lapua in Aug '16 because I shot out the Barrel in my custom .300 Wby chambered Rifle, and I wanted to see what all the Hub- Bub was about with the .338 Lapua.

    Out of the box, it delivered <1moa. The rifle likes everything Commercial I have fed it, but really performs well with a Load I worked up using a 300gr Hornady Accubond. I shot a 6 round group at 200yds that was 3/4" with one flyer at 1.3" due to the shooter suffering from Cerebral Flatulence.

    The fluted barrel does a respectable job cooling things down between shots. I shoot in Southern AZ where barrels take a long time to shed heat.

    The Action is solid, but I have had difficulty getting used to the Bolt travel while ejecting spent cases. Requires some effort to fully open.

    It is difficult to load the magazine. It requires great concentrated effort to press a cartridge into it. The only real negative I have found. It's not a combat rifle, so probably not a big deal.

    The trigger is smooth and very crisp. The fact that it is adjustable is a BIG plus in my estimation.

    Recoil is actually less than I expected considering the caliber. Much of this is due to the Muzzle brake that came with the rifle. However, there is a trade-off. The noise is Brutal. Double up on the hearing protection. (Plugs and Muffs!)

    Removing the Muzzle Brake does tame the noise, but point of aim (not accuracy) will be affected, and felt recoil is noticeably increased. Although the recoil is greater, for me it was still manageable. Just to clarify, I have been called a bit a of recoil junky.

    All in all, I am quite happy with the rifle. I get performance on-par with my custom rifles at a fraction of the price. Great Job, Weatherby!
