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.

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.

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 talk bad about the .257 Weatherby and the 270. I have my reasons, and some of them are to piss people off. It works every time.
