Why no 270-08 ?

[winmag]

With a 243 a guy could neck up pretty easy, or a 308 you could neck down.

With all the talk about kid/women friendly cartridges I don't know why no one has done this.
Is there a reason that there isn't any real 308 parent case necked to 277?

I mean we've got it bracketed on both sides with the 243, & 7-08. Then we've got the 308, & 338 Fed, so why no 270 wildcat?
Seems to me like it'd be the one to benefit as far as case volume, & bullet wt goes.
Anybody got any idea?
I'm kinda brainstorming for a build. Now, Im a very opinionated person, so Don't take it personally, but I'm not a fan of any 6.5, or 7mm in any configuration so that's out. The 338Fed just seem like a ballistic nightmare. And the 308Win frankly bores me to death. So, that leaves me with the 243. Ok, i know it'll do the job, but so will the others I've already mentioned. It just doesn't strike me as anything but a big coyote gun. Ya ya I know a ton of ladies who've killed Elk with them too (not impressed).

Please understand I'm not "bashing" anyone's favorite cartridges here. I'm also fully aware of the ballistic advantages of the 6.5, & 7mm's on paper. I don't need a tutorial on it. I just want something different, for my wife & daughter.
I'm a Huge 270, 30, & 338 fan in most configurations. They perform well on the critters we hunt in "out west". Plain & simple. But, For me, the 308Win case capacity alone rules out the 30, & 338 as ballistic dog turds, and the 243 (to me) is simply a cross over gun from varmint to thin skinned game.
I've got an old Model-70 in 243 that'd be a great platform for a build, so Why not a 270-08?

Seems like a fair amount of people have done it judging by my google results...sounds cool. Wonder how it would perform with 110s and 130s. I will have to look into it.

Ackley calls it out in his books, but was not his design

Why not just go with a .25 Souper? Wicked little caliber. Essentially a .257-308 Win, is basically what it is.

.25-08 (.25 Souper)

Recoil is virtually non-existant, potent, and capable.

You can buy dies for it...Special order from Midway & you can have them in 1 month to your door.

RCBS 2-Die Set 25 Souper (25-308 Winchester)

This caliber is intriguing me.....Might have to go find me a cheap 700 .308 Win and build one of these....

You can use Lapua .308 Win brass, I already have thousands of 210 primers, powder, and .257 caliber bullets....

Hmmmmmm......

I was thinking of using 130-140 gr bullets with it.
After a few searches it seems a 130 at 2900-3000 is very achievable.
It's also a run of the mill velocity with an average-mid load for a 270Win with a 130gr bullet. (Tho the 270 Win can be loaded quite a bit hotter)

Next Question:
How much actual difference in recoil between the 270-08 & the 270 Win?
A 270-08 with a 130gr bullet @ say 2900- 2950ish fps, with 46ish gr. of powder.
Or
A 270Win with a 130 gr bullet @ same speed but with 10-12 more grains of powder?

I'm confused why this didn't catch on a long time ago
Any thoughts?

Only because I have a huge fondness for 270's, & was thinking of launching 130-140gr bullets.

Same here as far as intriguing. I Love the Lapua brass idea too!
Ya I've got powder, primers, & bullets. Brass wouldn't be too hard to score being a .308

IMO the differences in your suggestion vs. the 7mm-08 make it almost not worth talking about. I have a 270win and a 7-08 and the ballistics are so close. You've got to get out past 400 yrds before it even matters (for hunting scenarios). Now...there is more heavy bullet options in the .284 and you can actually make a good LR target rig on the 7-08 if you want.

Recoil wise, IMO my 7-08 kicks a little less and it weighs less than the 270 I own. The 7-08 with a 160+grain bullets recoil is about the same as the 270 with a 140.

Also, if I wanted more punch I'd go with a 284win or the 7saum.

My two bits...

Yeah, I've got probably close to 1K once-fired .308 Hornady Match brass from back before I reloaded. I use them for load development with my .308, so I don't waste shots on my Lapua brass.

I am a huge fan of 7mm calibers, and .257 calibers. I'm fixing to build a .280 AI to add to my 7mm collection, and hopefully I'll have a .25-06 Sendero SF barrel on it's way Monday. I replied back to the guy with the barrel's PM saying I agreed to his price, but haven't heard back from him yet. And that will be turned into a .25-06 AI or possibly another .257 Wby....I haven't made up my mind yet.

I'm guessing that the difference wouldn't be too much . Please build one and let me know.

Here ya go.

I say build one and let us know. I have often wondered myself why it has never been done or hardly done. I know what you mean how the caliber is bracketed, but hey... it would be worth a try. I think you could use the 150 class bullet with good success. Though the 130-140 pills would definitely be potent medicine. Here in PA, the 150RN is potent medicine for whitetails in 270. Works well in brush too.

I'm willing to say that the 270-08 would also be a good platform for a short barreled rifle. Use a 20-24" barrel for weight savings and carry ability. I'm liking the idea. Go for it and set us all straight!

Thanks guys.
Riley, thank you for posting that.

At this point it's still brainstorming, but I'm diggin the idea!
Another build is still a ways off, financially, but this one is worth looking into a lil deeper. Too many pros, not many cons.
Wondering why? & wondering why it's not vastly more popular?

#1 priority is a light weight, light recoiling rifle for wife & daughter that is capable of taking Elk at 300yds and closer. Preferably closer, but capable of farther. This is not intended to be a LR rig. Nor compared to one. I'm quite positive the 270-08 would fill this roll very handily.

Dear God man that won't kill an elk, haven't you been reading the internet I've come very, very close to buying a 270-308 reamer, I think your on the right track, besides a 270 cal will get you a some extra yardage because it's just better

Wondering why? & wondering why it's not vastly more popular?

Among commercial cartridges, there really isn't another cartridge that does what the .270 Win does at normal hunting ranges. I am a bigger fan of the .280 Remington, but in factory form it doesn't live up to its potential. The classic .270 offers a combination of high velocity, flat trajectory, low recoil, and good terminal performance that places is squarely by itself.

I really think the original .270 is a well enough balanced cartridge that changing it around a bit tends to dim its virtue. I don't know how popular the WSM version is, but it is safe to say that it is nowhere near as popular as the original. The 6.8spc is basically a niche cartridge for AR's.

From a big picture standpoint, if you put a .270 bullet in a .308 case, it goes from being in a class by itself to being bracketed by well established cartridges to which it would offer little or no advantage and be ballistically inferior.

I say this by way of attempting to address the question you posed. I am not bashing your idea. I think it will do what you want it to do. Since you are a .270 fan, you will likely enjoy the pursuit. In the big picture, though, I think the question of why it's not more popular has a lot to do with the fact that most .270 shooters are pretty happy with the cartridge in its classic form. It's a Classic Coke vs New Coke sort of thing. We all know how that turned out.
