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

JB,
You are getting a NULA in 257WBy, did I read that right?
If so, that should be very nice!

I've seen a .257Wby recently that I thought was IT! Kimber Montana originally .25-06, punched .257 Wby, modified for the same.

VA,
That would be very nice indeed!

Am thinking it would probably rate a NICE+P from most.

Data from loaddata.com

257 wby 24" barrel
100 gr speer
73.0 gr RL25
3545 fps

257 weatherby mark v [unlisted barrel length]
100 gr sierra
73.0 gr H4831
3596 fps


270WSM
100 gr speer
65.5 gr H4350
3585 fps

62.0 gr IMR4064
3645 fps

I didn't check twist, nor do I have any empirical data on accuracy. However, certainly an argument can be made that a .270 WSM will equal a .257 WBY with less powder. BC will begin to play a small part [likely very small at distances over 400 yds]
I don't have a dog in this fight, just curious.

Better yet...compare a 257 Roy shooting 120's, to a 280AI shooting 120's.

Of course it depends on the rifle. A heavy barreled 6mm with 55 gr. BT's @4200 fps is a sweet thing in the p-dog field all day, also hell on coyotes. Just has to be a dedicated vermin rig. Your nula on the other hand might look silly with a truck axel for a barrel. Either way when it comes to yotes, flat is where it's at.

In the typical 8 pound rifle how would the kick of a 257 Weatherby shooting 120s as 3400 fps compare to a 270 winchester in the same 8 pound frame shooting 130's at 3000?

Can someone tell me if under 100 yards it would kill deer better? I hope so! Thus I can justify yet another rifle!!

If your 6mm is already doing everything that you need it to do, the 257 might not add much to the arsenal regardless of it's greater capabilities...but a 7wsm might add some excitement perhaps??

EVERYBODY needs a new rifle. That's what makes us loonies.

Never had a 257wby, it sounds very nice.
I am thinking a M700 LSS would be perfect...

340boy,

Yes, NULA Model 28 in .257 Weatherby. I suspect it will shoot pretty well....

Whatever you like. But I don't much like heavy-barreled varmint rifles, after having owned several. Could go into detail but will just note that I haven't found any advantage in them, and their barrels take a heck of a lot longer to cool down.

I also have found that even with heavy barrels anything from a .22-250 on up means I can't see the bulet strike in the scope. All of which is why anymore my all-day prairie dog rifles are all sporter-weights chambered for AT MOST the .223. I have taken PD's with the .204 to over 600 and with the .223 to over 700. Also they are lot more pleasant to shoot hundreds of times over a couple of days.

Wow!
Should be nice, Mule Deer.
Enjoy...

With the Montana 25-06 having a 24" barrel, I wonder how close it will come to the 257Wthby.? Then there is always the AI version.

Still toying with turning my Ti into a 257 Roy. Took me a LONG time to play with one but it's certainly in my top 5 list.

did someone say Remington offered the cheap SPS in .257 Weatherby?

They do, I almost bought one a while back.

Edited to read: it was an SPS Stainless, sorry!

I'd buy 360 but not 3600.
6mm - 3000 fps with 100grain bullet.
257 Roy - 3600 fps
That's what mine do.

Maybe some valid points on the heavy gun but the 6mm will do head and shoulders better on the varmint/target side than the .257 in my opinion. The .257 Wby crosses that line.
