Home Forums Hunting & Shooting Ask The Gunwriters what will a 257 Weatherby do that my 6mm Rem won't do?

Just curious to know, from those who have used both on game.... thanks in advance...

Your 6mm Remungton can't start a thread of pitiful hatred over 20 pages long, as the 257Wby vs 300Wby has.

Burn out barrels faster, cost you a small fortune in factory ammo; and kill big bodied game over 300 yards from your muzzle.

The .257 is clearly the more powerfull cartridge.
By along shot. The 6mm is a great round, one that is very acurate and powerfull enough for deer sized game out to roughly 300 yards.
But I do not think I would use a 6mm on a game animal over about 400 LBs nor would I take it after somthing like a black bear.
Now the .257 weatherby is not evreyones idea of the best black bear round either but If I were hunting by glassing at a distance and spoted even a large black bear at say 250 yards and had a good bullet say a 115 grain TSX or a 120 grain partition,
seems like a really good combination to me.
Should roll that bear prety well, with a good hit. And with a better shot than me probably at a greater distance.
And while you could probably use a 6mm for caribu, in that open tundra country, not much would better than a .257 weatherby.

Roughly 3600 fps.

The 6mm Remington can get around 3200 fps out of a 100-grain bullet, the .357 Weatherby 3600 fps. The .257 Weatherby can also get 3400 fps out of a 120-grain bullet.

With 100-grain bullets the difference in trajectory is pronounced. With my own .257 Wby. sighted in 2" high at 100 yards, I can aim right in the middle of a mule deer's chest out to 400 yards and hit the buck in the heart.

With either 100- or 120-grain bullets the .257 Wby. generally hits deer-sized game noticeably harder. Of course, anything can happen with a typical lung shot, but most of the time the .257 will put them down quicker.

The 6mm Remington is a fine pronghorn and deer round, but the .257 Weatherby is a noticeable step upward. However, it also kicks more. To me the recoil is more like a .270's, and maybe even a little sharper. Whether or not that makes any difference depends of course on the shooter.

wow. i just ran those numbers at www.norma.cc with a MV of 3600 and 100 grain bullet with BC of .39 and the bullet is up 2 at 100, up 2.6 at 180, crossing zero at 283 and only down 8.4 inches at 400 yards. Holy cow.

According to reasoning found in these forums, the 308 works just as well as a 300 Wby. The 257 Wby vs. 300 Magnum debate has established that the 257 Wby works just as well as a big 30.

Using that same logic, the 6mm is pretty close to the big twenty-five. Therefore, are we to conclude that the 6mm is pretty much the same as the 30 Wby. So much for logic. I believe humans can convince themselves of silly thoughts given someone to agree with them and someone to put it in writing.

Q: What will a 257 Weatherby do that my 6mm Rem won't do?
A: Shoot a slightly larger bullet a lot faster.

Answer: The .257 Weatherby is spooky flat-shooting in the field. I've actually shot the two cartriges side-by-side and the trajectories are remarkably different.

Johnny is right about the practical game useage of the .257 Weatherby. It is one very amazing cartridge.

The 257 Wby is clearly superior to the 6mm Rem, if for no other reason than it pushes a heavier bullet faster, with that said the 6mm Rem has been one of favorite cal for deer and long range varmint hunting for years and i haven't been without one since 1971 and I have killed a number of deer with this cal and a truck load of varmints. My favorite 25 cal is the 25 STW with the 25-06 running a close second. Maybe one day i will try the 257 Wby, but since i have the 240 Wby which is my favorite of the Wby line up, I'm in no great big hurry.

When I read the first posting I was just about to say the same thing you did. Each has its' abilities and supporters. 20+ page arguments get started - just like if you called somebody's "mama" a bad name!

Dogger,

Since I live and mostly hunt at higher elevations (even some of the pronghorn country I hunt is several thousand feet above sea level, especially in Wyoming), the .257 Weatherby shoots even flatter than that.

With the 100-grain TSX loaded to about 3550, the trajectory of my 24" barreled Vanguard when sighted in 2" high at 100 yards is 3" high at 200, 1" high at 300, and 4-5" low at 400. This is from actual range shooting. The 400-yard impact is a little wider because that's where elevation starts to make a little difference, say the difference between 3000 and 5000 feet above sea level.

It's also a very accurate rifle, with 3-shot groups averaging half a minute of angle out to 400. From what I hear from other shooters, this isn't too unusual.

I like the .257 Weatherby so much that a second one is on its way.

I mist also point out, however, that this is not a slight on the 6mm Remington, or any other cartridge. I have a 6mm Remington and .240 Weatherby, a .250 Savage 99, two .257 Roberts, and one of the European walnut-stocked .25-06 Ruger No. 1's that Lipsey's was selling a couple of years ago, and too many other rifles chambered for a wide array of wonderful cartridges.

Personally, I have never been able to understand why most shooters apparently have to like one cartridge (or bullet, scope, etc.) to the point of having to prove another is inferior. From my experience, they are all very good at certain things.

I also think the .257 WBY is really a hot number. If after all the numbers are crunched, maybe the best for Western deer and lopes. My problem with the WBY's is their stocks. Unlike others on the fire I still haven't warmed up to them.

No. The "logic" that is wrong here is figuring that "A overlaps B is true" and "B overlaps C is true" implies "A pretty much equals C".

In other words a person saying "a 6mm is suitable for a lot of the same applications as a 257" and also saying "a 257 is suitable for a lot of the same applications as a 300" does not imply they have said "a 6mm is pretty much the same as a 300".

Pretty much lost interest in the 257 Wby. years ago, when I noticed that it required roughly about a 25% increase in powder for a 6% improvement in performance, compared to my 25-06s.

Know a few that are very fond of their 257s, so I'm happy for them, just never wanted one of my own. Everyone should be free to chose what excites them.

Dogger;

The 6mm doubles as a varmint round better, but the .257 Roy is a friggin' laser.

Just curious, but what is your 6mm?

I'm not so sure of that. For prairie dogs either one is too much for all-day shooting. For larger varmints, maybe the 6mm would be better on rockchucks, and maybe not. A great many of my rancher friends have gone to the .257 Weatherby for shooting coyotes. These are the guys who do it professionally, because coyotes eat some of their profit, and they can aim right on a coyote out to quite long range with the .257 and make him really, most sincerely dead.

JB,
How about some details on the new Roy? Inquiring minds want to know!

NULA. Should be here in a week or two.
