.257 WBY MAG - AMMO TEST 

Weatherby is putting out 257 Wby ammo with Hammer bullets. Check them out. Hammers give around 200 FPS faster than other bullets of the same weight. Impressive.

Gotta get the copper fouling out of it. 257 is stupid hot and it has to be cleaned up after about 20rds. Roy designed it for an 87gr boolot that you can't get anymore. Welcome to the 257 club.

At the range this morning. Testing Ramshot Grand in a 257 Wby Mag. 115 Nosler Ballastic Tip. Norma Case. CCI 250. No problem getting to 3,505 FPS. It takes more than RL 26. Produces Spectacular Velocities.

When I was a kid, first learning to hunt. I was just presented with a box of ammo, and told to "Shoot this"! It wasn't until I started reading hunting & shooting magazines, that I learned how different ammo, all shoots differently! Just as this episode proves! "The more you know!" Thanks for all the hard work, and your ammo 🦉T🦉

My 257 wby vanguard loves the 110 grain Nosler Accubond. I have also had fantastic terminal performance from the Accubond on a variety of critters coyotes, pronghorn, hog, and Texas dall. I see Weatherby has replaced the Accubond with the ELDX. Good thing I have an extra box or two or four in my ammo supply.

Keep that brass and reload some 100 grain NBT’s to the max with RL22. Deer don’t move.

Looking forward to this one!

Awesome, hey can you do a challenge with that 257 Weatherby against a 7mm mag, love all your videos WhoTeeWho.

Those TTSX’s are some great boo lots for the Weatherby cartridges! My buddy’s Vangard .257 loves them , as does the 165’s in my .300 Wby. Mark V. In both, sub-MOA all day, screaming velocities and tough bullets that hold together and penetrate like a much heavier weight. Cup and core boo lots can grenade at closer ranges at Wby. velocities. That’s a nice setup too. The scope is a bit much for hunting for me, but for long range steel it will work great. Have fun !

Nice setup, but I will have to stick to my 25-06. Looking forward to your chrono tests and the long range stuff.

An EC Tuner V2 will bring those groups in for this factory ammunition and do justice to this wonderful cartridge. Another delightful video as always.

257 weatherby is a great cartridge. Deep down I really want one, but also want 25/06 which would prolly be better for the places I hunt honestly. I’ve reloaded a few 257’s for friends, and it’s a fun cartridge to handload.

My 2506 ruger numbe 1 shoots one hole 5 shot groups.

Would like to see you test the Hammer bullets accuracy and old school water jug plate test.

Just read on the 307....Looks like it is Weatherby's entrance into Rem 700 clones. I like it, as Rem is now an unknown.

Im glad the Barns bullet did so well. Ive been hearing good things about how that bullet does, so it will be cool to see how it works for you in your other testing videos, as well as hunting with them

Thanks for more material on the Weatherby. That is one very sweet rig. Would be interesting to see speed data when doing groups. Will go a long way to explain any wayward shots. Also good to know if your rifle gives variable speeds with a cold bore or not? You are a darn good shot, no question. What can tighten groups when you shoot from behind a bipod is having a place to “anchor” the feet in order to pre-load the bipod, this can reduce the jump a lot. Maybe see if you can add an edge to the front of your shooting table. Thanks for another great presentation 👌🏻👌🏻

You should shoot a few with the silencer on then do some without the silencer.

Super excited for this one!

While scrolling through the videos, you had me at .257! That round also happened to be Roy Weatherby's favorite caliber...

For sure Minute of deer on all of them. And for most hunting cartridges that would be just fine. But that 257 Weatherby Mag is putting out some serious ballistics. Only at 550 yards it hits the magic 1000 ft-lb and is still trucking at over 2000 ft/s. I guess it deserves a 0.5 MOA load.

Interesting caliber. Haven't seen it much so I appreciate you testing it out today. Thanks WTW....I hear the deers whispering....lol 👂🦌🦌🦌

The ttsx in my .270 Weatherby is lightning with whitetail.

the .270 and the .257 are my favorite Weatherby cartridge designs. Laser-beam fast and capable of accuracy.

I come here for all the NEW Caliber models, out there! I never even heard of a 257 Weatherby Magnum!

Good video ! I will add though that in my experiences I've never had a rifle shoot its best groups with a bipod compared to a sandbag rest. Also I've found a can increase groups at times.

Same as your led sled. Your bipod feet are not tied down. They’re moving around all over the place. You need stops on your bench to load up against then your groups will halve.

Great video as usual sir. Keep the great content coming.

That’s a heck of a rifle and cartridge!! I’d like to get a weatherby in 300wby. Nice new shooting bench!!! 👍🏼

I have shot a number of different bullets/hand loads out of my 257 Wby Vanguard. The 100-grain TTSX produces the best groups. The 120 Nosler Partitions come in second. I have those two loading for hunting here in PA.

👍😊 for different types of ammo not bad.

I talked to someone at Weatherby a few years ago, re a recommendation for an 'all rounder' cartridge for 257w, for short & longer ranges, medium-big game etc. and the 100tsx was noted. One of the advantages I think is penetration/blood trails etc, especially at shorter ranges where ELDX and Interlock bullets tend to have trouble staying together (3500fps! ) and for big game.

I predict the Barnes will be sweet!

I think your bipod got you. It was making some crazy bounces and the vertical stringing was probably the result

This will be close to my next setup 👌

The can on the end is messing up the natural vibrations and hindering the function of the floated barrel. Try it without the can.

When you shot the other day did you use the same rest set up? That could change how the rifle responds. Shoots good though.

Great interesting vid..awesome caliber...that was a expensive test...imho the ttsx are my favs anyways, Happy to see the results..thanks WTW...! ..I think its interesting how the eld's are stringing horizontal..hmm.

Now Ruger needs to make an American in .257 and show Weatherby how its done! Still on the look out for how Ruger did after returning your .450 Bushmaster. :)

Been shooting a 257 wby for 20 + years. I love it and I admit to bias. I state that fully, but .5 Moa groups with full power loads should be easily achieved with this wonderful cartridge. 117 gr at 3350 fps, .5 to .75 moa [from good firing position] and a rifle / calibre combo that shoots well off hand is a dream combo in my book. Biased - yes. Hundreds of proven data points in the bank - yes. Wby mark 5. Macmillan stock. Scopes by meopta and zeiss. Testing conditions provided by Scotland.

A 120gr Partition is a Lightning Strike on game in .257 Weatherby !!! A Great Round !

Mine was a 2 shot group throw the 3rd real thin barrel so i would shoot 2 let it cool then shoot the third round it works with mine i shoot 100 grain ttsx great for deer 🦌

Warm bore groups I think would be interesting. Or 5 shot groups to see if it tightens up.

Dag, that thing sure can sling a bolt ! It's going to be interesting to see the accuracy at greater yardage w/ optic.

Hey mate, if you find your groups opening up for no reason, copper fouling could be a cause. I owned a .257 Wby and l found this to be the case with mine. So if groups open up it maybe time for a good scrub! Great vid as always!

The .257 Weatherby is a laser, and it would be interesting to test it against body armor, the speed of the bullet should do the trick.

My Vanguard likes the TTSX as well. One caveat since I'm not a huge proponent of barrel break in, but mine got more accurate with every boo-lat after shooting through about 60- 70 rounds with a thorough cleaning between each change of bullet.

Hey Booty I'm really liking that Weatherby rifle that thing looks really cool and you've got some good groups with it I would like to know how many feet per second those weatherby's are putting out and also I really like that new shooting table you got that's a whole lot better than the spoil you were sitting on with that rickety table you had.

One sweet rig.

I did some experimenting.With some tuning forks when I was younger and the longer ones vibrated the longest and the shorter one didn't vibrate nearly as long and settled down to normal a lot quicker.This experiment lead to me.Beleiving that the same holds true for a shorter 22 inch berrel over the 26 inch berrel for the different types of hunting I do would be more practical for more accuracy from a free floated berrel that doesn't vibrate as long.And I could improve the accuracy for all shots and follow up shots and with certain bullets and powder.have the same power as the older 26 inch berreled 257 weatherbies.not shooting hammer bullets with a 1/ 10 twist rate on my 257 weatherby vanguard.

I will always love the #406 area code the best, but I gotta respect Weatherby for repping their new area code (my second favorite😉), #307.

I wish that I could get the 110 eld-x I like the way they shot out of the 25-06 they were one of the most accurate bullets I’ve shot in the it but they’re not available for hand loading right now

I shoot the Weatherby loaded 100 gr Barnes TTSX out of my 257 wby vanguard and constantly get .5-.75 MOA three shot groups.

Great video buddy

You should try bedding the action to reduce the size of the groups. It is a relatively easy procedure on most rifles. I watched Cave Dweller 1958 bed the actions on his rifles, easy peasy. Cheers from Oz.

All will be around or under 1". The best will be under 1/2".

Great caliber.

Good groups!

Evening everyone

Cool video thanks man

Im wondering if switching bullets is messing it up, and causing the other bullets to shoot poorly. Its especially suspect considering you shot the ttsx first. Id say clean it good, do a couple foulers, and change the order. And maybe order a couple more options from wby. As a huge weatherby fan, I'd hope it would do better.

Those ttsx bullets look good on paper if they dont just whiz rite on thur deer 120 gr. ballistic tips will be your best bet and load them yourself great vid.

I guess the same holds true for alot of older rounds with less powder capacities or even more.

Feeds sweetly, that 307. If you get the gun bedded, you might well eliminate that 3rd shot flyer. Nice gun mate.

Here's the thing with groupings and actual hunting. What matters most is does your rifle put the first shot where you want it IF you do your part under field shooting conditions. You know who misses shots? Guys who only ever practice from a bench. That's not to say those guy miss most of their shots but I've seen more guys miss deer and elk who really never practice from anywhere other than the bench or a solid tree stand rest than any other type of hunter. When I was young after we sighted our rifles at the bench we'd practice shooting from various positions you might find in the field and there was a big difference in the ease or lack thereof in hitting the target when shooting from a field position. Also, every rifle I had access to that would put the first shot where I wanted it never failed to put the second shot where I wanted it even if bench rest results suggest that shouldn't be the case. Why? Well, an accurate first shot usually ensures the animal doesn't go very far so the theoretical exponentially in creasing miss radius people love to crow about doesn't come into play when your deer has only moved 10 yards. An animal that has gone farther than that will almost always require a change of rest and a different angle if not a complete change of shooting location. So you're probably not firing a follow up in that case for a minute or two. Barrel cools down and the gun shoots to the same point of aim again. And usually inaccurate guns are labeled so because the third shot is a flyer. Two shots though are almost always enough for deer and elk, moose antelope etc... But, dude, what about a charging bear at 20 yards. Umm, big target, well under a hundred yards so far less deviation and the accuracy of the weapon is likely not going to be the limiting factor for actual accuracy in that situation. I'm not opposed to small groups. It's just that they really don't matter as much as people make them out to be. Get your first two shots within 2 inches and you'll be fine for pretty much any real world hunting situation.

I had a Howa 1500 in 25 06, it was a great shooter. I sold it to get a Vanguard Lazerguard In the 257 Weatherby. But Now cant find a Lazerguard. Bummer

Letting it cool is one thing but it would e interesting to see how things would change if you cleaned the barrel between each 2 shot group

as crazy as it might sound, the ttsx will do even better if the barrel only has barnes copper inside it. i don't know why but they do. try giving it a full clean before your ttsx sight in.

Get those blaze orange hats in stock. Hunting season is HERE! Thx for showing the bullets. Copper for up close. Lead for long range shots. (Copper getting better at low velocity expansion now like hammer or maker) barnes lrx ttsx

After each hunt or when the bolt don't cycle as good.

This cartridge is ridiculous, my buddies ptsd kicked off when I fired it the first time. I personally like the 87 grainers, but I can't find them, got a box when I bought the gun. I don't care for the interlocks, but the 117 grain soft points are really stable. If you reload your 257 check out hammer bullets, they have variety of different weights all the way down to 70 grains I believe.

I think I need one too

I love my .257 Weatherby. It is LONG. I think it is an Antelope gun for sure or when you have to reach out and take an animal that is a little smaller than your standard deer. Have fun. Ammo is $$. I buy a Box a month no matter what the cost.

Either the forend is very flimsy or your action screws are loose. Can see a ton of movement between your barrel and forend. Definitely check your action screw torque . Could really benefit from bedding the action as well

It might be that having the different materials of the bullet makes a difference.

I would retest without the can and see how it does then. The barrel may not like that weight hanging off the end of it.

Awesome 🎉

Hey, are the threads on the muzzle 1/2x28 or 5/8x24?

You might want to use your rifle rest,instead of the bi-pod, bi-pod is great for field use &hunting, but I'm going to say,,for sighting in the rifle rest may be a better option..just my thoughts,,"& thats a nice rifle"":)

It's going to get better as you shoot it more.

I think the Barnes will do the best

Dam barrel gets hot fast on 257 got to get u a barrel fan.lol.But for real u got to wait forever between each shot.$$$ not a cheap thing to figure out.

This is a sweet rig. Is there a 25-06 vs 257 video in our future?

Alright, let's do it, and you are a daisy when you do!

🛑🛑 What is the Core Content of the ELDX? Is the Bullet Core a Partitioned Bullet?

What do they charge for that ammo? 2 bucks a pop?

Fast and light. Ttsx is a winner for deer hunting. Other two better for varmint.

Clean the bore between groups it will make the groups tighter just a bore snake is better than nothing at all.

Maybe simply the difference between a leadsled and a wobbly bipod?

Nice! 💪🏻💪🏻💪🏻

I wish I had a 257

Doesnt look like too bad recoil. Its gotta be less than my 300 Wby Mag Ruger #1. What does it compare to?

Put the muzzle brake on it and try it.

I bet those groups would tighten up with a sandbag instead of bipod

👍👍 on video, How will the 257 pair up with the 25.06

good shootin😮

Nice range shoot, keep your powder dry, Steven 7

Lmao with the hand at end

What's the speed on these ?

Hey, you're getting about a quarter inch group firing one-shot groups😂
