  1. my favourite weatherby

    By peck November 17, 2016

    I hunt and shoot large whitetails in NW Ontario , Canada . of all my rifles I just cant help picking out the 257 for that big buck . ammo is scarce up here but still findable and always reloadable . I prefer 117 grn. weatherby factory its outstanding

  2. .257 Weatherby Magnum Accumark

    By Jay O. September 09, 2016

    The .257 Weatherby Magnum cartridge is amazing in itself, and the rifles being produced in this chambering continue to amaze me with their accuracy when using factory ammo. Whether at the rifle range with my brother and his 50 plus year old Southgate Mauser .257 Weatherby Magnum or my not so old USA made Accumark .257 Weatherby Magnum, the quality from the very beginning to today, is very admirable of the dream Mr. Roy Weatherby had in mind when developing high velocity rifle cartridges. We have taken a number of long range whitetail deer and New Mexico pronghorn with theses rifles, and the results are devastating to say the least. We love our Weatherby rifles because of the repetitive success we have when the time comes to harvest our game animals.

  3. I have hunted with the 257 weatherby for the past 5 years now and i can not say enough great things about this caliber. I have shot both deer and antelope here in Wyoming and the gun and the bullet has performed without flaw.

    By Torgy August 02, 2016

    I have replaced a number of my hunting rifles for the 257 Weatherby. This round out performs so many other calibers that I have used over the years.
    I purchased my Weatherby rifle in 2012 and could not be more happy with it. I shoot mostly the 120 grain Nosler and I have killed several Antelope and 4 deer here in my home state of Wyoming and all have been a one shot kill.
    Last Fall I shot a antelope buck at 425 yds and the antelope ran only 20 yds and dropped dead. That antelope scored 81.7 Boone and Crocket.

    I am in the process now of purchasing another Weatherby mark V in 257.

  4. The best

    By John Henry August 23, 2015

    I have hunted and shot everything in North America (except polar bear.). All of the game died on impact. The 257 weatheraby mag. Is the greatest.
