X-Bolt Speed LR

26" Bbl./7.5T/.270Win.



Elegant solution.

Will this become the Std. for the 21st Century?




GR

Why would it? Great 7mm bullets are everywhere.

It be as good as 280, 30-06, 6.5-06, and so on and so on. It’s where you hit them that counts. Grandkids slay hell out of pigs and deer with a 243

Wonder if they keep a Standard 270 SAAMI chamber in it?

Look pretty sweet. May buy one eventually. Just bought
an xbolt speed SR (first xbolt) and am impressed so far

Lou

Advertising that it shoots factory .270Win ammo.

... and hand-loaders can load heavier.


165 gr. ABLR would be an interesting affair past 300 yards.

Have an old pencil Bbl. M700 that have been threatening to do this to, albeit a 24" Bbl. w/o brake.

Be interesting to see how fast they push it.


If this trends - it might also drive production of heavier Partitions as well.




GR

Nope, just like the 6.8, 17 wsm etc.

Think it is more about the longer ranges and maybe heavier game.

Heavier, more efficient bullets.

And, it can still shoot regular .270Win/150 gr.


The caliber has already proven that it works reliably.

If it can push 165 gr. high BC bullets, w/ an SD of 0.307, to .280/175 gr. (SD=0.310) velocities?

It will then possess that same performance, with less recoil.

Something that it has lacked.




GR

More like the .280 AI, which is thought to be ideal.

And w/o all the hassle of fire-forming cases.




GR

A 168 gr LRX would sing!

I see nothing wrong with it, if its your cup of tea. I would be interested in it

Where have you been? The 280AI is a SAAMI chambering, and factory rifles, factory ammo, and good brass is available.

And with a great many more good 7mm bullets available, why not just get the "ideal" ?

7mms need so many bullets just to come close to the great 270/130 combo which killed more game than most of the 7mms combined:) Also why have 7mm when there are far more bullets in 30 than 7mm. Only a few more 7mm bullets than 270 but literally 2-3x 30 cals than either. Silly and unimaginative argument. I would expect better from the fire home of the rifle loony

Lou

Please read again. I said "good" 7mm bullets. To simplify, I meant bullets with high BC (not 277/130).

The OP seems to be interested in a rifle with long range capability, so a 7mm would be the obvious choice based on high BC 7mm bullet selection. A 6.5 would have advantages too.

I do love the 30, and I have a bunch. But the recoil of a 30 with 200 grain plus high BC bullets is more than I like, or need.

I was pulling your chain a bit since you are crumudging the 270 fun a lot of 270 fans have waited for

As for obvious 7mm these days. I dont agree. The 270 now as 165 ablr, 170 berger vld, 170 nosler ballistic tip, 155 barnes lrx, and sierra 175 tgk. Not to mention some good stuff from the smaller guys like badlands, cuting edge, and hammers. All excellent high bc heavy and “heavy for a mono” hunting bullets. No reason to choose a 7mm unless you want to shoot the real heavyweights like berger 195 or want to shoot match bullets. I and a lot of other hunters would not use match bullets for hunting so that leaves the really heavy 7mms which are icbms which would only show a real benefit over a lighter 7mm or 270 higher bc in some specialized instances. That is how one can rationalize a 270 choice if you are struggling to understand:)

Lou

And if the military adopts the .277 bore, 7mm and 6.5mm will probably be obsolete in 10 years.

Sorry Lou. I guess I'm just a "glass is half empty" guy.




I do understand. As they say, you can rationalize anything.



I'll wait

Triggers could be a touch lighter but accuracy in mine has been superb.

ya!

GWB

Because the .280 AI is just barely a legitimate cartridge... for now, and for how long?

Who Doesn't chamber for the .270Win?

Am reloading quality PPU .270Win brass, harvested from $13/20 box factory ammo.


The bullet market is just now starting to respond to the new high-twist/BC .277" demand, and there are quite a few already.

It is now THE military caliber.


And if the high BC bullets, or similar SD heavy bullets, perform the same, they will do it with less recoil.

The .270Win Is Ideal... save the SAAMI twist rate.




GR

Yep. Ol' Jack O'Dwyer is probably doing jumping jacks with excitement in his grave.

Glad to see that it is chambered for 280 AI and the PRC's. Does it come with the bolt on the left side?

Yep. If I wanted a 26" barreled long range lightweight rifle, that 7mm PRC would probably be high on the list. The 280AI too, but I think my 24" barreled 280AI's would work just fine.

Must be a misprint that the 270 weighs 5oz more the 280AI, 7mm PRC, and 7mm Rem Mag?

Same Bbl. diameter, smaller bore, thicker Bbl., same performance, less recoil...




GR

Even a 280AI fan isn't fool enough to claim it has the same performance as a 7PRC or 7RM . . . . 270win falls well short.

I say get one and work it out.

Personally, I'd rather just kick tires and make holes in paper than worry about what we think on this place. We only have ourselves to please. Busting caps will tell the tale.

Honestly?

.270Win, 1:10 twist, 22" Bbl., Cup-n-core 150 gr. Speer (or 140 gr. TSX) bullets... does what I need.

... Hunting out to 400 yards.

But have considered re-Bbl'ing an old M700 pencil Bbl. .270Win w/ a PacNor varmint weight 24" stainless, and a faster, 1:8 twist.

Now that high SD/BC bullets are becoming available, it would be an interesting rig.


And one can almost smell the fear of the 7mm fanbois... now that .277 is THE Military caliber.

8>)




GR

WTF happened to the standard for the 21st Century?

Oh, I get it. Seems the only thing you shoot is your mouth. Probably haven't bought a gun in 30 years.



As Finn said, the 277 is just an aberrant 7mm. (look it up)

The fear is strong w/ this one^...





Look it up.

8>)


P.S. little one: how old do you think this .270Win rifle is?


... Bet you were already out of diapers.


8>)




GR

I've got nothing against the 270, it's a fine caliber, but I wouldn't trade my 280 Rem for a 270 Win.

Finn Aagard be damned.

... and Ross Seyfried.





8>)




GR

Well, I've never thought of myself as too dumb to make up my own mind and need a gun writer to tell me what to do or what to hunt with.

What would you be hunting with if you couldn't read?

Nothing against gun writers....

Apparently the JOC-sniffer can read, except maybe for a ballistics chart.

He still needs to detail how the 270 equals the 7PRC and 7RM.


Too bad Winchester couldn't copy the 7x64 Brenneke a little better. The 277 bore never needed to exist, and it would have been twisted better too.

So, little one...

You feel ballistic charts kill game?

8>)


Out to 400 yards, the game won't know the difference.

And the .270Win will do it with less powder and recoil.

It's a more efficient cartridge.

Look up P.O. Ackley's thoughts on the .270Win.
(hint: there is no .270 AI)


You don't have to like or understand that, little one.




GR

The .270Win.

Started w/ a coupla .30-06's.

The first a 1903A3 sporter, and then a very nice scoped Winchester M70.

The 180 gr. loads affected my precision, and, while all-day shootable, the 150's lacked both the SD and BC for my requirements.


The 150 gr. .270Win had the same SD as the 180 gr. .30-06, but shot like the 150 gr. .30's, with better BC and trajectory ta boot.

Also like the 6.5x55mm/140 gr. quite a bit as well, for a light weight, aperture sighted rifle.




GR

Whether it makes a difference or not, there is no denying that the 7PRC and 7RM offer more performance than the 270 (physics).

Whether it matters or not, depends on the game. That's why the 7RM was developed. Flatter trajectory than the 30-06 was needed, but the 270 was believed marginal for elk.



And for educational reading, there is a 270AI. MANY 270 shooters are spending a lot of money trying to make their 270 the equal of the 280AI.

270AI educational reading assignment

But unfortunately they never can, due to the larger bore of the 7mm, the small advantage in capacity of the 280 case, and the better high BC 7mm bullets.



Have fun researching the rifles you'll never own

I've always thought that 6.5mm was just a little bit too small for average big game, 7mm would be fine except who wants the recoil of 175 or 180 grain projectiles from a .30-06 size case or larger? Not me. A true 7mm which is almost exactly .277 is about right for hunting most game. And it seems that the military's tests have also shown it is the ideal size for their purposes. More high bc .277 projectiles will soon come out.

So you feel that ballistics tables kill game.

Aren't you special.

Bet you need a bench and a bi-pod as well.


Didn't do your homework either, little one. (Reading for content is a skill, too.)


P.O. Ackley ( the "A" in A.I.)





Should have stayed in school, little one.

8>)




GR

What other factory 270 fast-twist rifles are available?

What 270 loaded ammo with a high BC (>600) is available?

I've got the book. 1962 copyright.

I know you're living in 1925, but powders and bullets are far different than in 1962.

The Military just adopted the .277 as their primary rifle caliber.

The 6.8 Western, the first higher-twist commercial .277" cartridge, ttbomk, was just released not too long ago.

It took the 6.5 CM Ten Years, and aggressive marketing, to rise to it's current level of popularity, given that it is essentially a 6.5x55mm in short pants.


On the other hand, since the advent of the 7 RM for heavy bullets, and the 6.5 CM for higher BC, the .277 community, which is predominantly game hunters and not paper punchers, have been asking for higher twists and better bullets.

And that is now being addressed.

Note: Rifleman pride themselves on how Close they can get to their game before they have to shoot.

So, your academic perspective is somewhat retarded in the hunting fields.

400 yards - is a long field shot, as is even 300 in less that ideal conditions.


A Higher twist .270Win, with a higher BC, will still shoot w/ the same precision and mild recoil, but make those longer shots, on heavier game, a little easier in those less than ideal conditions.


Your Sniper fantasies not withstanding.




GR

LGBTQ+270 for the Win…

Is there, or is there not, a .280 A.I... but no .270 A.I.?

P.O. ACKLEY explained it to you, you just weren't paying attention. (again, reading for content is a skill)

How many factory rifles are chambered in .280 AI as opposed to the .270Win?

How many are sold?

How about ammo manufactures/offerings/cost?

Wait for your 7mm snow-globe to settle.


As for modern power and bullets?

The ones here, and on their way, will make the .270Win shine even brighter.

That's what terrifies you.

Say a 165 gr. ABLR, BC=0.62/SD=0.307, on top of a full charge of RL-26 for ~ 2,900 fps MV...?

...if ballistic tables killed game.

8>)




GR

Your Bud Lite is showing.





GR

Your arrogance and ignorance shows in most of your posts, GaYrandimal.

So you have nothing.

Because you said so...

Have another Bud Lite.




GR

But, at a buck/round just for the ABLR bullet...?

Can most likely get close enough not to need it.


When Speer makes a 165 gr. high BC Hot-Cor bullet... will be the time to really get interested.




GR

Still waiting for answers . . .

What other factory 270 fast-twist rifles are available?

What 270 loaded ammo with a high BC (>600) is available?




Not too terrified. I get 3030+ from my 24" 280AI with RL26 and a 162ELDX 631BC

Bullets less than .50/ea.

Pay attention, little one, because ballistic tables don't kill game.

SD, however, is a good indicator of penetration, which, among other things, does kill game.


162ELDX 631BC: SD=0.287

For a .277" bullet, that SD would be ~ 10 gr. less bullet weight.

ie: ABLR .277/150 gr. BC=0.591 SD=0.279 MV~3075/24" Bbl.


When you can't find your inexpensive HDY ELDX bullets?

... it will be b/c they shifted production to their new, high BC .277" bullet.


... if ballistic tables killed game.


8>)




GR

It's a valid question to ask, how much high bc factory ammunition is or will be available to take advantage of the faster twist or will those who buy these continue purchasing "normal" .270 cartridges and see no advantage at all? They might as well buy a Ruger American. That's one of the advantages of the CM's and PRC's, they were designed from the first for appropriate long-range bullets. I rather like the idea of the rifle, but question the real utility of it in .270.

Of course Browning's intent is to sell rifles regardless of utility and I am OK with that.

That is the issue.

Will ammo manufacturers jump on the bandwagon with ammo that won't shoot well in most 270 rifles on the market, and then weather the nasty reviews and phone calls?

Or will gun manufacturers jump in, producing fast-twist 270 rifles, when there aren't enough long range 270 ammo offerings to justify them, or shooters to buy them?

Browning did, but will others follow suit, or just focus on the 7mm PRC?

I know if I was buying that particular rifle to focus on long range hunting it would be a 7PRC, without question.

Interesting, but Nosler shows the MAX load of the fastest powder for that bullet topping out at 2918

I can run the 7mm 175 ELDX Hornady near that speed in the 280AI.

BC 689 SD 310

Clearly a better elk load.

And a 7PRC can run it over 3K.

... if ballistic tables killed game.

Think the elk will notice?

8>)


Till HDY comes out w/ one:

Sierra Tipped GameKing: .277"/175 gr./BC=0.560/SD=0.326.

(P.S. Nosler's loading tables aren't the only ones out there)


And that 175 gr. 7PRC at 3,000 fps?

~ 30 ft-lbs of recoil from an 8.5 lb rifle.


Good luck w/ that from field positions.


To 400 yards, the .270Win/150 gr. is all a rifleman really needs.

A higher twist/BC bullet - will make hitting at that range in less than optimal conditions easier.

A higher SD bullet - will increase penetration if needed.


That's all.

Takes away any real advantage the 7mm's had.

And being the new Std. Military caliber... believe that a lot of R&D will go into state-of-the-art .277" projectiles.


The Future is now.




GR

You will look back on these as the "Good ole Days" of the 7mm caliber.

8>)





GR

How is the 6.8 Western doing? Other than BACO, hardly any rifles chambered for it. Other than BACO, no other ammo manufactured for it.


Here's an article on your wet-dream savior:

Guns and Ammo 277 Fury

I found this to be particularly salient:

Will there be additional cartridges planned for a “Fury family?” A representative with SIG Sauer told me, “Yes.” There is no timeline yet, and that person wouldn’t say what was next in line. I’ll step out on a limb and predict that the next one will be a 6.5mm SIG Fury, and I’ll bet that it will be more popular than the .277 SIG Fury proves to be! The .277 SIG Fury arrived to us first because it is simply a commercialization of what SIG Sauer has already been developing for the U.S. Army’s NGSW requirements. The civilian market wants rounds in 6.5mm, 7mm and .30-caliber. That’s why I’d be willing to bet that a 6.5mm SIG Fury is next up. Like the .277, it would push a 140-grain bullet at 2,970 fps from a 16-inch barrel. A 24-inch barrel would send it downrange around 3,100 fps.


Good to see that a 24" 6.5 Fury would only be about 100fps slower than a 140 in the 280AI

Took the .270Win a while to catch.

Took the 6.5 Creedmoor Ten Years.

How are they doin'?


.277" - is now the Std. Military Caliber.

How are the .223, .30-06 SPG, and .308Win doin'?


Enjoy your Good-ole-Days...


8>)




GR

You're the one living in 1925

The civilian market wants rounds in 6.5mm, 7mm and .30-caliber.

The Future is now.

... and the 7mm, isn't in it.

Like the Military, soon the civilian market will want .277" as well.


Enjoy your Good-ole-Days.

8>)




GR

If it outsells the 7mm PRC I'll eat a box full of them.

Like the 7RM when it came out, the 7PRC will be a big hit and a good seller.

... until folks get around to shootin'em, especially in the field.


Almost everyone I know that loved the 7RM... sold it off for an easier rifle to shoot well, mostly .270Wins.

And rifles were 8.5-9.0 lbs. scoped back then.

The 7PRC, out of a 6.5 lb. wonder? Will either be grim... or extremely loud.

Either of which will produce Minute-of-Basketball precision from the neophyte, or even average shooter.


Look forward to the booming used market in the latter stages of your Good-ole-Days.

8>)




GR

I understand.

If you're afraid of a 30-06, any 7 magnum probably isn't for you either.

Have you considered the 243? Fast twist 243's are pretty common now.

Again, little one, your inability to read for content has led you astray.

Precision shooting from field positions requires much more skill than your concrete bench, lead-sled, and sandbags.


My field shooting improved after shifting from 180 gr. 30-06, to 150 gr. .270Win., which is about the same as M2 ball.

Better hits - make the .270Win a better game round.

Everybody that got rid of their 7mm and 300 Mags knows that.


Marksmanship - is a skill.

... and ballistic tables don't kill game.


Try to remember that.




GR

10-4 Flinch

Learn to shoot from field positions, and then we can discuss yours.

GR

Thought this was interesting...





GR

I was speaking more about the platform, it’ll be gone within a couple years, no one else will follow suit.

The .270Win/150 gr. is a pretty tough field round to beat.

Haven't fooled w/ them, but have heard of difficulties getting the ABLR 150 gr. to stabilize in a Std. 1:10 twist.

By far the best long range Nosler choice for the cartridge.


Getting a 1:8 twist Bbl., for that alone would be worth it if 600 yd. shots were a probability.


A really heavy Partition for the woods would be a bonus.




GR

.270 Winchester - Testing New Bullets and Powders

"... With scope, the rifle weighed 8 pounds, 11 ounces, about a pound more than O’Connor preferred. However, one thing I discovered when using heavier bullets with new “Wonder Powders” in other .270s is higher velocities make an O’Connor-style rifle kick more like a 7mm Remington Magnum. The extra weight of the Mossberg, and its thick, soft recoil pad made shooting a bunch of test loads more pleasant, and probably more accurate, especially toward the end."
