O’Connor had his choice to use every exotic cartridge ever invented through 1978 and to use them all over the world. And he chose the .270 Win.

It's not doing anything new. It's selling more rifles and ammunition. That's the entire reason they're doing it. Same as 260 Remington, 264 WM, 7mm RUM & Stw, etc.

Again, this isn’t for broad siding whitetail at 80 yards, it’s for dialing on the elk of a lifetime at 540 yards, and not losing any velocity while shaving almost a pound of barrel off the rifle you just carried 17 miles and 4000 feet up.
The 308, 270win, 7mm rem mag and 300wm can do this all day long and have been.

Would be cool to get a little extra out of things like 7mm-08 without messing with a new chamber.
That's an interesting thought.

What will be really interesting to see is how the technology is applied to other caliber. Will 80ksi .308 Winchester be an option? 300 Win Mag? .50 BMG?
Interesting questions. What would happen if you run a 7 Rem Mag at 80K psi using the special brass. Would velocity of 80K psi Rem Mag=velocity of 80K psi 7 Backcountry?? If so, would that many people want to pay what it take to buy a new gun, just to get that performance in a 20" barrel?? I don't know, but it raises a lot of interesting questions.

A 270win is better than a 6.5 PRC.
I disagree. Further you go out the PRC will have less drift. Also, it will be shooting higher grain for caliber therefore higher sectional density bullets with better bc’s. 6.5PRC with a Berger 156 is lethal.

One of the bigger questions will be the bolt. I remember when the Sig Cross came out there were some that had to get +p bolts to run the 277 Fury. Then all of the Cross rifles were outfitted with it. I think you’re going to be cornered into buying a factory offering from Seekins, Geissele, etc. until custom action manufacturers test it with their bolts.

270win has been lethal all the way to the plains of Africa. The PRC stands for Profit Reaping Cartridge. It doesn't kill any better but if you want to punch paper at 1000 yds, it's better at that.

Nothing wrong with a 270, but dead is dead in an animal. 270 is a legacy cartridge, of course it’s been more places as it’s been around 10x as long. 6.5PRC shines at the versatility it offers, I run mine in a long action so I can swap between it and 7PRC. But if one wanted to shoot mag length or factory ammo, it can easily be shot in a short action as well. The further the distance the more energy the PRC will retain at impact. Better for punching paper and steel at 1k yards = higher precision with no reduction in lethality.

I agree but if we had long heavy bullets back in the 50s, these cartridges would already be used by the same calibers they had back then. The only changes made would be barrel twist. New bullets = new rifles =more money. It's not really doing anything new but making money. I another 50 years how many of these are still going to be around?

6.5x55 was designed for 160gr bullets. The main difference now is that you have rangefinders and ballistic computers and good scopes. In the 50's you probably never knew the exact range.

A little bit off the subject but how come 7mm rounds aren't more popular? I'd buy a 7mm-08 in a heartbeat if ammo were easier to find. On paper it seems like the perfect whitetail cartridge.

I just bought a 7mm-08 this year, but haven’t had any trouble finding ammo.

Good to know. I don't see it often. I really want one on an AR-10 platform.

What’s going on now with rifle calibers is similar to what’s happening with compound bows. There’s very little real world improvement in calibers for the average hunter.
This new 7mm likely would serve me well on the elk mountain, but I killed a bull this fall with my 300 WBY and had no idea about this new rifle that I might need.

No hand loading. No care.

I don't understand why new cartridges seem to trigger people so much.

He chose the 270 win because in a time before rangefinders it was the best compromise between flat trajectory, manageable recoil, and acceptable terminal performance. He loaded his 270 win so hot the book will tell you it’s about to explode. If he could have gotten higher pressure safely, he would have.

That’s not true. Before rangefinders velocity was king, heavy for caliber bullets in fast twist barrels is a direct result of rangefinders getting so good that drop can be calculated on the spot, making wind drift the biggest unknown.

New cartridges disrupts the order of things in people’s minds. And it was stated earlier in this thread, but many of us have seen the WSMs, Creeds, PRCs, etc and they’re really not much of an improvement over what’s been around for a while. Also, ammo for standard cartridges can be hard to find because of the massive production of 6.5 creed and 350 Legend.
