was just looking at my Nosler book. With that new 110 gr Accubond, it has the same ballistics as the 257 Wby and the 110 gr Accubond. BC's aren't the same, but the diff is meaningless. Very interesting. Don't need no stinkin Wby.... :-)

270 is fine if you want to be boring, while ignoring the greatest hunting implement ever devised by mere mortals.

You could probably extend that statement to "don't need no stinkin' magnums".

Mere mortal....

To the op they are close performance wise with thier bigger bullet choices.

The 257wby lights up with 80-100gr bullets due to velocity.


Donate to TX Youth hunting program.... better to donate then to waste it in taxes

What I didn't say was that the 257 Wby needs a 26 inch barrel to reach those MV numbers, while the 270 does it with a 24 inch barrel. Isn't that interesting. I used to think the Wby was something special.

Now, if Nosler would just make a 100 gr Accubond for my 260.

I suppose you only drive a 4 cylinder car because you don't need a V-8 to drive down the highway either. rofl

Now Scooter...I'm just presenting the facts. And I drive a big ol freakin truck with a V8.

I never was a belted magnum fan, and now I (and you) can exceed 257 Wby performance with a 270. Pretty cool, but it sure takes the wind out of the sails of the guys that thought the 257 Wby was the baddest flamethrowing earth shaking sendero caliber of all time. Jack O'Conner would be so happy....the 270 might just be the perfect caliber. Whaddaya think, Fireman? Is it you that talks bad bout the 270? :-)

I have taken the day off from reloading to watch football and stir the forum pot.

It can't be the perfect caliber, because a 270 WSM and a 270 Wby are better. grin

The .270 WCF is the "almost perfect" caliber. The .300 WM is THE perfect caliber. smile

Lower the standard weight on one caliber and raise it on another then claim their the same? Are you really trying to say that? And I'm pretty sure the ballistic's are not the same once it leaves the muzzle.


Yes! A Weatherby does kill them deader.

I'm just saying that the 270, with a new 110 gr Accubond, will push it faster at the muzzle than the same weight Accubond in the 257 Wby, and do it with a shorter barrel. BC is higher slightly on the Wby, but makes almost no difference in trajectory out to 600 yards. That's what the Nosler book says. That tells me that the 257 Wby has no reason to exist, except for the folks that just want one. The Wby mystique is fading a bit.

I guess you could say that the 130 gr bullet is standard in the 270, but you can't compare that to the Wby since the Wby can't shoot a bullet that heavy.

A 150 in a 308 can match/surpass the 150 in the 270 according to the same book Same as 130/140gr. All of this in a short action! I guess the 270 is obsolete as well. Sorry for the sarcasm, but you see how cherry picking your numbers doesn't tell the whole story.

It's easier to push a bullet (of the same weight) faster in a larger bore. That's all.

Run the numbers of the .483 115VLD at 3400FPS against the 150VLD (of .518) of the 270 at 2850 fps. Hardly obsolete. More energy in the Wby out to 1500+yds despite a weight disadvantage of 30%.

I like the .257 Wby. too. If I had to pick one to go with the .300 WM it would probably be the .257. The guys on here got me onto it and it sure doesn't disappoint.

I didn't notice the 270 and 257 Wby similarity with that specific bullet until yesterday. The reason I did notice is that I was thinking about maybe using the 110 Accubond in my 270 and I just checked against what the 257 Wby could do, and I saw that they had the same weight Accubond. I was honestly surprised that the 270 could push it faster. Very interesting. Now Scooter has told us that the Wby has more grunt at 1500 yards, and I really didn't know that. I guess I'll have to get one for my 1500 yard deer hunting. But...the fact remains that out to any reasonable hunting distance, which is the only reason anybody would ever want a 257 Wby, the two calibers are essentially equal, and the 270 can do it without free bore and without a 26 inch barrel.

It's just data. I'm hunting with a 260. The 270 is parked, and if I brought it out for use I'd need to run through a bunch of ammo before I ever bought the first box of 110 gr Accubonds. Still, the data does detract from mystique of the 257 Wby. That won't please the die-hard Wby fans.

Of course, you could put that 110 gr Accubond in the 270 Wby and get some crazy MV numbers.

Well, I guess I should clarify. Using VLD bullets and appropriate muzzle velocities for the given calibers (115 in the 257 and 150 in the 270), it has more energy from 0-1500 yards. I also proved (using your flawed logic) that the 308 and 270 are essentially equal.

The BC of same-weight bullets in 25 and 270 are "a bit different" but that makes no difference downrange.

If you believe that, then you might be interested in getting in on a great investment opportunity.



Kind regards, charlesb

Geez, scooter, I was talking about the same type and weight bullets in two respective calibers. Simply put, the 257 Wby does a real fine job launching the 110 gr Accubond. And, the 270 does it a teensy bit better. That's all I've said. If a fellow likes a 110 gr bullet at 3500 fps, he doesn't need a long barreled, long throated 257 Wby. Just shoot it in your 270.

And when did I even get the 308 into the discussion? That was you. I was trying to keep this a sort of apples to apples comparison, and off you go with different calibers and bullet weights and bullet types.

I heard that many British soldiers after WWII came home convinced that the SMLE and the .303 was the best rifle known to mankind, shooting the best cartridge.

Military personnel all over the world tend to feel that way about whatever they carried, or saw used.

My father came back from WWII with a strong preference for the Thompson submachinegun in .45ACP, but he never went through the rigmarole necessary to own one in the US, as a civilian.

I don't see the comparison. It's the same grain bullet, but its a different caliber. So its not apples to apples.

Man, you kill me with the wake up calls on weatherby, .270, .25-06 etc. Got me rolling on the floor. It really don't make a whole lot of sense with money to spend so much on belted catridges that are harder to reload for and don't last as long as something far cheaper-that does the same thing "within reason". That said, brother, the Weatherby is still sexy as hell. And it still wins further downrange and still does shoot flatter and hit harder. In .257, with the energy figures of available factory loads, it looks like a dream to me.
Yet I am the new guy and not the long range guy,prolly ought to keep quiet. Flame away
