So Will the .270 Win Overtake the CM's and PRC's?

[budlight]

I have a .270 wsm with a 1-8 twist. For LR hunting, it's a pretty darn good set up. Alot of knockdown power with the 165-170 gr projectiles.

I like to kid with my 270 wsm buddy. On chrono days my 29 inch barrel out runs the wsm by a hair. 5 extra inches of barrel.

As to higher BC 7mm. If more peop[e bought 277 the supply would come. 165 matrix at .650 BC is above lots of hunting rounds on .284 dia. for similar weight.

I have O percent faith in Nosler's LRAB BC claim. Brian Litz does all the data and testing of all the low drag LR bullets and his numbers were much lower than Noslers claim. Also the range data doesn't jive with the impacts. Usually 1-1.5 moa off on long range testing. Good bullet, incorrect ballistic info given. The BCs are much closer to the original Accubond before the LR version came out. There not much different In numbers when tested.

At a 600 yard drop test my 175 gr ABLR 7mm, my group sizes were horrible and 6 inches lower than predicted.
At 200, all touching. Go figure....Back to Berger 180 for now.

I am happy with my wife's Tikka 270Win. It has 1/2" to 1" MOA right out of the box with various bullets. She only hunts to 400yards. The 270 has more diameter and more powder capacity than the 6.5CrM so after we looked it over we went with the 270. I contemplated getting her a barrel with 8" twist so that she could shoot 156gn Hammer Hunters, maybe reaching 3000fps with R26. But her gun shot so nicely right from the start that she and I agreed that her "poor man's magnum" would do everything she needed to do with either the 110gnTTSX at 3375fps, 119gn [AKA 117] Hammer at 3350, and 129LRX at 3150 [<1/2MOA pix].

My advice for someone wanting to build an 270 with 8" or even 7" twist is "Go for it."
It's time has arrived and there are 156gn and 168gn Hammer bullets waiting to take R26 pixie dust to new levels for the 270.

Let's look at the 7mm mag. It pushes the 162 around 2950 fps with over 60 grains of powder. My 284 pushes the same bullet 3000 fps with 53 grains. Different powders if course BUT the don't run the same powders for the best performance. H1000 in the 7mag vs RL17 in the 284. Both top powders for the cartridge. Over 12 grains more powder in the 7mag. I do not shoot the 7mag as the 284 replaced it. Call it efficiency or plain old common sense. Less recoil, less powder, less cost for equal or better performance. I'm not trying to dispute a word, just stating some cartridges do better with equal or less powder and same bullet weight. BC plays a huge part as well. Obviously why the 6.5/7s are at the top of the list.

It would be better if the term "relative efficiency" was used to describe all this.

While I'm interested in seeing what will happen with the 277 fury, I think it will have the same effect on the 270win as the 6.5cm had on the 260:

Not much other than giving more bullet options in custom rifles while simultaneously overshadowing it.

Sure the guys with custom 260s are still around and shooting them, but if you were looking to enter into long range shooting would you buy a factory 260 or a factory 6.5cm?

In my view the 277 fury is too much a change in case design and pressure tolerance to help the ol' 270w very much in any other way than getting new bullet designs out there. The same holds true for the 27nosler. Too much more powder capacity. I think the 270s best chance at resurgence would have been the 270wsm being saami speed with a faster twist back when it was released.

Also, look at the numbers. 264, 277, 284. The 6.5mm is 0.013 smaller and the 7mm is 0.007 larger. So the 270w is bracketed on both side by cartridges like the 6.5prc/6.5x284 and the 284/280ai. And both 6.5 and 7mm already have great high bc bullets. It seems to me that there would be so little change in bullet weight and recoil between bullets of the same BC in 277 that the 270 doesn't really bring anything to the table over the others. Especially the 284/280ai

That's understandable. Out to about 400 yards there close. Beyond that it's much more noticable when the BC numbers aren't accurate. Really gets out of whack beyond 600

I think the big gun makers are kind of like harley davidson they watch and see what people are doing to customize the products or what custom builders are doing and then they may follow suit

Or, they may not ...... depending on how big they think the market is for the new development. Sometimes they get it right, and sometimes they don't. Hornady's marketing department got it right with the 6.5's. If/when that market is saturated, some other bullet diameter may be the next "new frontier." I think you're right that the big manufacturers keep their fingers on the pulse of the market, and react to what the custom builders are doing to modify their products, or build completely new stuff.

I think manufacturers try to make their own trends. Look at 284 Winchester and 280AI, everyone knows what they can do but they are hard to find as a factory chambering.

Do you think any ammo manufacturer wants to make .270 ammo that will keyhole in 99.9% of all .270 rifles?

They would rather copy a 6 Grendle and call it 6 Arc or create .224 Valkyrie and have huge issues out of the gate.

6.5 Creedmoor was an anomaly where Hornady started a trend that actually worked and caught on but it still took years before Savage and Remington started building rifles and it became a common large frame Ar chambering.

It's only my opinion. I'm all for every caliber offering high bc bullets for LR shooting but the truth of the matter is that with the 6.5/7/7.62/.338 offering so many excellent bullets for the LR/ELR game, I don't see any company dumping time and cost into the .277. I'd love to be wrong and see it happen. Just gives me a reason to build a LR .270

Isn't Sig Sauer dumping money into the 277 Fury?

I'm currently getting a 1/8 put on a 270wsm, nosler has a 165, berger 170 , matrix has a few heavy bullets, honestly with some RL26 with a 24 inch barrel I dont see why it wont push a 165/170 3000/3050, that's more than enough to take down anything except griz imo. With 3/4 the recoil of a 300win

 

[Starlite]

I own 2 6.5CMs and love them. I'm over the moon to use my new 270win Overwatch. And, as far as I'm concerned the CM has 70+yers to go before it can have the ultimate bragging rights. The 270Win (should have been call a 7mm in my opinion but that for another debate) has definitely earned that.
just my 2c

No it won't.

So what do we have? A Long action, 26"+ barrels, faster twist barrels, high BC heavy bullets, low recoil, brass CHEAP, brass neck is wonderful for longer higher BC bullets, RL26 pixie dust, every manufacturer has a .270 in current configuration of 1:10 BUT with advent of the higher BC bullets, heavier and need for faster twist barrels, is this the next NEW caliber to win over everybody?

Heck, my 24" sporter barrel is shooting 150 ABLR at 3075 fps with RL26 with absolutely no pressure so what will a 26"+ do with faster twist for heavier higher BC bullets? Recoil is actually pleasant and can shoot all day for probably anyone. The downrange ballistics are pretty darn good with the higher velocity, higher BC, heavier bullets that the .270 Win can actually do with faster twist and RL26 pixie dust.

So what do you think? Does the old girl have a chance? I do. Then again, Hornady has not branded it as a CM or PRC so probably no chance at all.

This is my next build!

Been saying this for years. Since day of the CM cult beginnings.

How about the 27 Nosler guys?
