Just get it man!

Oh, I just struggled with this for the last few months. If I won the lottery tomorrow I would order a 257 Roy the same day!! It's unique, it has history, and it's proven!

Is no one going to mention BC?

There ya go

My wife hunts with her grandpas 257wby, she loves it, I’m a fan of it, it does seem to kill the deader. I wouldn’t hesitate on buying one, I’ve been eyeing a 240wby for coyotes, yes I hate them that much.

How in the hell do I talk a man out of buying a 257 Weatherby?

Price of ammo? Most people who shoot Weatherbys don't care about the price of ammo.

Cost of the rifle? Again, most people who buy Weatherbys care little about the cost and I might add that Weatherby has done a great job at getting their price down on various models.

Barrel life? Few Weatherbys will ever see more than a couple of hundred rounds fired in their lifetime.

Sorry I can't do it!

As for the 257 it is without a doubt my favorite rifle, delivering everything I want from a hunting rifle. While it certainly has the goods to take down a bull elk as many have proven I personally keep it to deer size. If we're going elk hunting I'm taking a 300 Weatherby, nothing in North America would make me go any larger.

A 240 pushing a 75 grain pill 3600 fps is some serious yote medicine.

Wouldn’t it be awesome

Great round not seen very often, if wanting that performance I would probably of 6mm-284 or 6mm-06, sure they are not a Weatherby but brass is easy to make from parent rounds and easy to come by good brass. But if you are not a reloader or just want the 240 "go for it" Your $ get what you want

If you want to consider another speed queen with a few more bullet options I say you give the .264 win mag a look. Very similar case capacity and velocity but a touch bigger bullet.

if he wanted to do that just buy a .270 wby mag.

There is that new 27 Nosler round that is faster than the .270 why mag. So many options

If I was to buy and use a 257 Wby, I’d reload for it and use the 110 gr Accubond. Per the Nosler book, I could push it to about 3500 FPS. But...with my standard old 270 I can push that new .277 110 gr Accubond to the same 3500 FPS. That takes some of the excitement away from the Weatherby, unless you just want the Weatherby.

Of course, a pro loader like Chad might be able to use that extra Wby powder capacity to get more than 3500 FPS.

I may be wrong but the same weight bullet isn’t gonna have the same effect in the .270 as the .257.

I bet a 110 grain 257 would perform nearly identical to a 110 grain 277 both at the same velocity. The Star of the show is the velocity not the diameter.

I loaded 90 grain HP's in my 270 at around 3400+ fps it was nasty on varmints.

Just buy a 3006 and load 110 grainers, no Weatherby needed. There, i talked you out of it :-)

Lots of good info here. Thanks y’all!!

Once a man has his eyes set on the pinnacle of hot nasty speed, timeless style, and unmatched performance theres no talking him down from that ledge! He has to take the plunge and harness the lighting bolt like Zeus himself and buy a .257 Weatherby Mag!

It’s a whole different bullet. Sectional density is different, the length, width, bullets inter cavity, bearing surface, and .........ballistic coefficient is different meaning each has a different environmental factor


You would want to get with the larger surface area object as it’s going to have a larger profile to displace energy and also have more friction in the air, then it’s same weight but smaller and denser counterpart.

While all those things are true and different, I don't think that add up to much of anything in how the round is perceived. Load a 110 grain accubond at 3500 fps in both and I think they will behave extremely similarly, small differences aside.

I'd have to dig but I've got a couple of boxes of Hornady 243 with 70 grain ballistic tips, I believe they pushed the 70 above 3600. I push the 58's at 3950 from my Styer pro hunter and it's 26 inch barrel. The 240 was the only round Weatherby made that made me shake my head, it simply duplicated what was already out there. We were playing with the 284 back then, never had a 6mm-284 but did have a 25 and a 6.5-284. Weatherby slipped on that one. I've got a couple of loads for a 75 grain from the 6mm-284 that run around 3800 to almost 3900 ftps. With that said I'd still like to have a 240 to add to the family.

Perceived? It’s physics thus why there is only two 100-115 bullets .277 offerings and one is all Cooper(actually a bigger physical bullet then cup and core or bonded counterparts) every yard past the muzzle the differences in performance become more apparent.

Yeah my 243 sends the 75amax at 3400, it works great.

But when you actually quantify that difference its not significant. At least not to me.

Physics isn’t why there aren’t many light bullets offered for the 270. Lack of demand is the reason. If it wasn’t for the 6.8SPC, there wouldn’t be a 110 gr Accubond.

The only point I was making earlier is that you can get that 3500 FPS with the 110 gr Accubond. What I left out is that, per Nosler, you can get that MV in the 270 with a 24” barrel, but it takes a 26” barrel with the Weatherby.

I wasn’t saying to forego the 257 Wby in favor of the 270. Just making the point that you can get that velocity in that weight bullet with a rifle you may already have.

At 100 yards, the 257 has an energy bonus of 50 ftlbs over the 270 and the same weight Accubond. At 400, that increases to a bit more than 100 ftlbs. Does that matter much? Your call on that. And for comparison, both calibers with that bullet weight have more energy at 400 yards than the 6.5 CM with a 140 gr Accubond leaving at 2800 FPS.
