Roy Weatherby’s personal favorite. Travels 3,870 fps (80 grain bullet), giving you the flattest trajectory of any 25 caliber rifle in the world. Suitable for long-range varmint shooting but ideal for big game hunting (depending upon bullet weight).

  1. Tigger

    Well the problem here as in Alberta, Canada, we cant get rifle ammo and I am finding very hard to find any 257 weatherby ammo anywhere, so dont know what weatherby is doing, but not good for sure.?????

  2. J Piccer

    Great ammo.Dropped deer at 238 yards in its tracks.Through both shoulders

  3. John Henry

    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.

  4. Torgy

    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.

  5. Jay O.

    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.

    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

  7. jd

    Excellent caliber at 280 yards

  8. TheDuke

    Started shooting the 257 in 2012 and have killed at least two white tail a year since with it. All have been 1 shot 1 kill and haven’t had to chase any of them more than 100 yards, (that was shooter error). I use the 100 grain Barnes TTSX. Shots have ranged from 75 yds to 375 yds. Primarily used in clear cuts and crop land! This is my favorite gun in my arsenal.

  9. Stu

    I purchased the Weatherby Backcountry in the .257 Weatherby Magnum rifle the year before last and it has become my favorite rifle by far. It is an extremely accurate rifle and the .257 Weatherby Magnum is a hard hitting round. The Weatherby rounds that I use are the ones loaded with the Barnes bullet. Shot a nice Whitetail on a Tennessee ridgeline last year and the rifle felt like a natural part of me; came to the shoulder well and shot placement was perfect. Highly recommend the Weatherby Backcountry chambered in the .257 Weatherby Magnum. The only downside is the cost of the ammunition. Great gun, great caliber!!!

  10. M Sharp

    I’ve taken over a dozen large Whitetails with my .257 at ranges from 75-367 yards. All have been quick, clean and humane. I’ve never had one take more than a few steps after impact!

    If you do your part, the ammo will definitely do it’s part.

    I shoot the 110 Accubond’s and I couldn’t be happier with the performance and accuracy! I can “cloverleaf” three shots at 200 yards from a bench. That is extremely impressive from factory ammunition.

  11. Jclark

    A few years ago I decided to find a new gun. I wanted something a little more enjoyable to shoot and after a little research I decided on the .257 weatherby and I couldn’t be happier. I’m using the 110 accubond and it is a absolute laser. My longest shot is 407 yards on a hog and a couple whitetail kills at close to 300 yards. I’ve never had an animal go more than a few yards. Its hard to explain until you experience for yourself. Don’t let the cost of ammo deter you from experiencing the incredible 257 weatherby

  12. Groundpounder 69

    The 257 Wby Mag will reach out and touch game animals out to 500 yards without any problems as long as you do your part holding the crosshairs still .
    Every deer I hit drops like a rock . I use 110 grain accubond .

  13. Jhood

    Great flat shooting hard hitting .25 cal. Have one in a vanguard deluxe then had a custom rifle built in 257 wby as well. Can’t believe how flat it is and how well it kills . Used it on 20-30 whitetail over the years and not one have left their tracks. Kills better than my 06 and 7 win mag without the recoil. It has quickly become my favorite deer round and have used it out to 500 with just a hold over.

  14. Old Man

    I have been shooting the 257 for what seems like forever. I have killed far too many deer, hogs, and coyotes to remember. T he salient point is that this cartridge has never failed me. Too, it is a real help that all factory bullets seem to shoot nearly to the same point of aim. I do not know how many different rifles I have owned and shot in this cal., but right now I am shooting the Mark V ultra light, and it is a joy.

  15. Fatboy

    I’m 73 years old , so I don’t do much hunting anymore but I still love to shoot. I go to the range 5 or 6 times a year. I load my own shells for two reasons. Cost and they are more accurate. People complaining about the cost of shells must not be picking up their spent brass. Once you have your brass it’s not that much more per shell than any other round. Besides, you MUST pay for the finer things in life.

  16. beard

    257 with laser genetics subzero mounted to leupold 4.5-14
    if u can see’em
    u can kill’em
    lethal out to 400 inn dead of night

  17. Chuck

    I have two 257 Mag Weatherby’s a custom and a standard mark 5, they have amazing killing power for game up and including Elk. Put away your 06 and your 7mm Rem Mag this does a better job with far less recoil the only drawback is that the ammunition is a bit pricey. So if you want the best…pay for it or start reloading!

  18. jd

    highly accurate and pleasant. good for sambar deer of 180 kg

  19. WESTERN MULE DEER HUNTER

    THE SPECTACULAR RESULTS FROM HUNTING WITH THE .257. 80GRAIN DOES ONE SHOT KILLS BUT NOT LIKE THE 100 TO 120 GRAIN. IF YOU LIKE DEAD IN THEIR TRACKS. 257 IS THE CHOICE. IT WILL CONSISTENTLY WOW YOU SHOT AFTER SHOT. I SHOT 50-60 DEER AND ANTELOPE (LOST COUNT) . IT COST A LITTLE MORE TO GO FIRST CLASS AND YOU WILL NEVER REGRET IT. 4.5 X14 LEUPOLD IS MY FAVORITE ALSO.

  20. Silverback

    Finally drew a tag for Kansas antelope rifle hunt. I purchased my 257 Weatherby specifically for this hunt. I chose the 100 grain spire point for my hunt. I last ranged the “goat” at 336 yards as he was walking on an angle further away. One shot later, I thought he vaporized. No where in sight. Gone. I knew he could only be down. 1 shot, on the strong side of 350 yards, that goat fell when the bullet hit him in the lungs. I’ve never attempted such a long shot, but felt I could make the shot. The combination of my Weatherby Mark V and Weatherby 100 grain spire point did the job. Don’t worry about Weatherby doing its job. You only have to worry about yourself. I’m purchasing the 115 grain for its superior coefficient, energy and trajectory on Whitetail/Mule Deer this season.

  21. Tom, BC, Canada

    I LOVE my .257, have downed several deer with no complaints or issue. I really want to use it on elk? Shots will be anywhere from 100 – 400 yards in my area of BC. So wish me luck. I honestly do not see and issue using this amazing caliber with either the 110gr or the 115gr.
