Real-world difference between a 270 win vs. 270 Weatherby?
What's the real-world difference between a 270 win. and a 270 Weatherby Magnum both with 24" barrels?

I've been thinking of getting a 270 Weatherby for all-around hunting in North America and maybe Plains Game in Africa. This would complement my 300 Win mag. on some of the larger game hunts and I'd load 150 or 160 gr. bullets. It would also be my primary for some of my longer range hunts using 130-140 gr. bullets for different deer, antelope etc.

Thoughts? Or should I just stick with a 270 Winchester?

Theoretically, you would be able to push more velocity with the .270 Wby, especially with 150gr bullets. But since you own a .300WM, you don't need the benefits of a .270Wby. The .270 Win has plenty of velocity for antelope / deer / pigs / coyote. I find it minimal for larger game, but is effective when used with good bullets and proper shot placement.

The .270 ammo is easier to find, cheaper, and easier for re-load. If you didn't have that .300 and needed a one rifle battery, then moving to the Wby might make sense.---But then again, I'm not a big fan of the Weatherby cartridges.

The 270 Weatherby is an odd ball round and not popular.

You will not find ammo for it and the resale will be poor.

Instead look at other rounds. The 270 Win, 7mm RM and 30-06 will do similar things and make much more sense.

I just bought a used Mark V in 270 Weatherby with a 26" barrel. I love it. 150g Partitions at 3250 fps make it an awesome sheep, goat, and elk rifle. I also love the 270 Win. Since you already have a 300 Mag, I agree with mdstewart that a 270 Win makes more sense. The only reason I bought the 270 Weatherby is that I've always wanted one, gave my 270 Win to my son, and I got a great deal. They are both great calibers.

ONE LESS CARTRIDGE IN THE MAGAZINE!

A factor that is well worth thinking about if you shoot in extreme wet or extreme cold weather.

For me, in British conditions, shooting at less than two hundred yards, that one extra cartridge trumps ANY velocity advantage that the Weatherby (or 7mm Remington Magnum) has over the 270 Winchester or 280 Remington.

The cartridges are in the dry and I don't have to fumble with wet or cold fingers to load an extra round.

Indeed the big advantage is that I can load the magazine, in the dry, with FOUR cartridges and then when ready to shoot work the bolt to put a round in the previously empty chamber.

ONE UP AND FOUR DOWN BEATS ONE UP AND THREE DOWN.

I have owned a 270 Wby and liked it, but in my opinion, it just seemed inefficient. It took too much powder to gain just a little more performance.

Mine was a tack driver.

Actually the same question could be asked between the 280 Rem and 7mm Mag, and the 30-06 and the 300 Win Mag. The differences between each of the standard vs magnum cartridges are about the same.

About 200 fps. Not enough to make any real difference in the field at any normal ranges. That doesn't mean that the Weatherby has no value though. I love my AccuMark in .257 even though I know it has little advantage over the .25-06. I wanted a .257 since I was a teenager - I've had three .257 Weatherby rifles in the past 30 years. Many times it is not about power or efficiency or logic - it's about what you want and what makes you happy. Don't let the nay-sayers disuade you just because they can't afford a nice rifle.....

Get both. I like them but the weatherby just hits harder. I know there is only so many FPS difference but it shows. If deer hunting I would probably pick up the 270 win but elk I would opt for the weatherby

250-300fps. I think it is all a mind thing. The magnum factor just sounds better just, think if the 270win. was referred to as the 270win. magnum. I read an article years ago in Deer and Big Game Rifles called The Magnificent 7, which compared the 7mm Rem. Mag to the 30-06 when using them on elk. Same scenario about 200fps. You can only kill an animal dead. Dead is Dead. It's all in what a man wants to use. I do say always bring enough gun though, you wouldn't take a 223 to shoot cape buffalo.

I only have the Weatherby version, but many of my friends use the Winchester. I think if you are going to be hunting where 200+ yard shots are a good possibility, I would take the Weatherby version. Not that it won't work within 200 yards, for me, the flatter trajectory makes it worth it. For some, it might not make a difference.

I also bought a .300 Winchester this year, I plan on using the .300 for my elk/moose/caribou rifle, and the .270 Weatherby for my deer/antelope rifle. That's the plan, anyway, and for hunting deer in thicker country around home, I could use either, but I won't know what I will use until I head out in the morning.

On another note, why get a .270 Weatherby with a 24" barrel? If you are going to get the benefit of the higher velocity, try to get a 26" tube. That's just me, not that anything I do makes any sense, though. Smiler

Personally, I like the 270 winchester. I would opt for the 270WSM over the WBY if I needed more velocity.

The WSMs and Weatherby's really come into their own with heavier bullets. A 165g spitzer at 3150 fps easily equals the 7mm Mag and is plenty for all but the biggest bears (and some would say it's sufficient for them with the right bullets).

Ballistics with 150-grain Nosler BTip drop in inches:

Cartridge.....MV.....100..200..300...400.....500...500fpe
.270 WCF...3000...3.6...4.3....0...-10.1...-26.8..1516
.270 WBY...3200...3.0...3.7....0....-8.7....-23.1..1756

So, no practical difference between the two out to 400 yards. No one can hold well enough on big game in the field to tell a difference in drop of 1.4" at 400 yards. And at 500 yards, only 240 fpe more energy with the Weatherby. No game would know the difference either, although perhaps the deer which steps out at 75 yards which would have less meat damage with the slower WCF cartridge.

Get whichever one makes you the happiest, knowing that in the real world it makes no difference. I love my AccuMark!

I have never owned a Weatherby because I never considered them to be a NICE rifle.

If you look at the ballistic numbers you will see that the 270WBY gives you around a 100 yard advantage over the 270 Win.

So if you want a 270 bore rifle, I would go with the 270 Win in a real lightweight rifle.

Personally I think if you have a good 300 Mag, then I would get a 308 with an 18" to 20" barrel, as to have a rifle lighter and handier when doing those hunts where you will not be shooting over 300 yards.

That way you can use the same bullets when reloading for the 300 and the 308.

If sticking with the 24 in barrels, I'd go WCF. The 270 Bee may be my favorite of all cartidges, but as stated above, the diffrence is neglidgeable. That being said - the bee IS faster and if you don't mind the price of brass and powder you get a little better trajectory, a little less wind drift, and alotta cool factor. Jump to a 26 inch barrel and you will have a noticeable diffrence in drift, especially out at 300 yards and beyond. You only live once.

Another observation is that, unless you've a shed load of 277" bullets is that if you want faster in 150 or 160 grain?

Do as I am and get a 7mm Remington Magnum. It'll give you a wide selection of 150 to 160 grain bullets that are always hard to find in 277" and also you can always load it to effectively 270 Winchester +P (if such a thing existed) levels.

I don't think that 270 Weatherby offers any practical benefit over 270 Winchester (in 150 or 160 grain bullet weights) that can't be in practical terms achieved more easily by 7mm Remington Magnum.

The nice thing about the 270 Weatherby is you can shoot Sierra 90g HPBTs at 3700 fps for varmints, 130g Partitions at 3350 fps for mule deer or sheep and 160g Partitions at 3150 fps for bigger stuff (elk and bear). No flies on the 7mm Mag either though

Yup, my son got his first elk with 130g CoreLokt PSPs from Walmart using the 270 I handed down to him two years ago.

Interesting thing is that 270 Wby velocities are often quoted from a 26" bbl and 270 Win from a 24" or even 22". This can often explain some of the Wby advantage in velocity.

My 270 Win has a 27.5" bbl and it best accuracyload puts a 150 NP out just at 3000fps with sub MOA performance. I can dump more powder in the case and get 3300fps but not with the same level of on target results.

Obviously, other rifles might and probably do give their best with hotter loads. That being said a 130gr at 3100fps and a 150gr at 3000fps with sub MOA accuracy are my preference. And so far everything has died out to 550yds, often DRT. Correct bullet choice and placement count far more than a few fps.

The other point is that when you get way "out there" yardage wise you are going to contend with hold-over or click ups anyway, no matter what caliber you choose. At less than 400yds the advantage is less in practice than on paper. You still have to get the yardage spot on.

Agree, I've been shooting 150g Partitions at 3030 fps out of a 22" barrel Rem BDL for about 40 years. I expect to get 3250 fps out of my 270 Weatherby with it's 26" tube. If I hadn't given my 270 to my son, I wouldn't have bought the Weatherby, but once I had given it to him, I got such a good deal on it I couldn't resist.

270 WBY: About 300% more for factory ammo for about 5% increase in performance. I like my 270 Win.

In 26" barrels the 270 will see up to about 2950 with 150 grainers and 3150 with 130 grainers. The 270 Wby will see 3250 and 3450.

I have also had 270/308 Norma and 270/300 Win.

If you are happy with max 270 Win ballistics any of the 270 mags will give those with reduced loads and no pressure and case life just this side of forever.

I have shot 100s or pigs and goats and 1000s of roos with both. One place where the 270 Magnum is better is with some heavy bullets that can be a bit hard but they work on the light game.

You can also easily make 270 Wby brass from 7mm Rem cases or neck up 264s. The will be a little shorter in the neck that Wby brass.

You can do everything with 150 grainers in the 270 Wby as they will be a good 100 f/s faster than 130s in the 270 Win. The Wby also puts a good 100 f/s plus on the 270 WSM.

How does the 270 wby act in a 22" or 24" barrel?

If one has a 270win or 7mmRM an upgrade to .270wea really makes no sence. However I had no rifle down in that area and chose the WEA round for the upper ballistical advantages it does offer in all bulletweighs up to 180grains over the .270, 7mmRM, 30-06.
Since I reload anyway, stuffing the x-tra 15-17grain of powder into a WEAcase has presented no problems so far Smiler

The are several blokes on a Denmark run Wby forum with both Mark Vs (26") and Vanguards (24") and in some cases the Vanguards were slightly faster.

As a side note the 270 Wby is Ed Weatherby's favourite.

But there is no way I would want 270 Wby with 22" barrel and especially shooting 100 grainers. They are already serious crackers in the 26" barrel. But if loaded back to 270 Win their blast is not as sharp as a 270 Win.
