Federals new cartridge any guesses?

I don't know who takes shots at game at 1000 yards. I've heard out to several hundred and 500 yards, but not more than that. If I'm confident and I know what the bullet can do, I might take a shot. But I know for myself, I'm 300 and in tops.

You have to remember- some gunowners and hunters are idiots, and follow dumb suggestions to the T.
 
Looks cool to me, but not so cool that I’m interested in buying one … though I’d like to shoot one if given the chance. I can get most of what I need out of 7mm-08 and the .208 Ackley, not to mention the 7PRC. But I do acknowledge the incremental advancement. I look forward to some good info about reloading the cartridge; I expect that will be a bit more involved, perhaps making it less attractive to many.
 
I was watching this review on YouTube this morning. He observed the same thing that I have shooting hybrid cases in my 308. The recoil is like unexplainably mild for the performance you get out the end of the barrel.

Federal's New Cartridge Will Blow Your Mind

I'm not doing anything crazy with my 308, i'm not turning it into a 300 wm. At best I'm turning a 308 into a warmly loaded 30-06. So big deal, why not just get a 30-06? But the thing is it doesn't recoil like a 30-06. It doesn't even recoil like a 308 to me. This sounds incredulous but I don't feel any increase in recoil pushing the pressures from normal 308 pressures up into the mid 70k's. If anything I want to say it feels like slightly less recoil than standard 308 loads I don't really know how to explain that and I had just attributed it to my rifle having a good stock, but now hearing someone else observe the same thing and struggling to explain it, I thought I would also mention it. My rifle for reference is a Lithgow LA102 in 308 with polymer stock and no muzzle device.

Also on a side note, he mentions in the above video that Federal told him they have proofed these cases at 110,000 psi.
 
Have you, or can you, do a side by side comparison of your hybrid loads vs. a few factory loads? I would be very curious to hear about the felt recoil difference between the two.

Do you have any trouble resizing the case or it sticking in the chamber after multiple firings? Does the steel casehead no deform enough to need resized, so you're just working the brass? I'm very curious about how this works, just not curious enough to try it myself.

ETA: I just saw you already responded to my earlier post with most of this. I missed that somehow.

I have but I don't know how I could quantify it in a meaningful way other than just shooting both and saying what it felt like.

I really don't understand why this is the case but I think it's just do to the burn rates of powder used affecting the temperature of the gas being expelled. I've noticed a couple times that slower burn rate powders in the same cartridge seaned to produced more recoil for the same or even sometimes less performance. The first example that sticks in my mind was working up a 270 load for my brother in law maybe 5 years ago. I tried RL19, H4831sc, and IMR4350 with the same bullet. I was replicating the factory loads he shoots which we chrono'd at 2800 fps. To get there with RL19 and H4831sc I was getting significantly more recoil than his factory load. When I tried the first load with 4350 I thought I was way off on the charge weight because it felt and sounded so weak but when I looked at the chrono data I was easily getting the target velocity. I noticed the same thing with my 375 Ruger after trying a few different powders.

I think when you still have powder combusting out the end of the muzzle, the gas temperature is very high and the continued combustion is maintaining that temp slightly longer and that it's producing kind of a rocket effect pushing the rifle backwards. If you've ever studied the math behind rockets, the biggest factor in rocket thrust is velocity of the gas, and the temperature of the gas is the biggest contributor to that gas velocity.

I could be way off, but there is something to it that I don't think is totally explained by just the mass of the ejecta.

No I haven't noticed any expansion of the case head. The stainless part is going well up into the sizing die and I'm full length sizing each time. I don't see any resistance sizing them or chambering them. The first batch of 50 cases I converted I loaded 5 times, and then moved on to shooting the rest of the cases I converted, so I don't know yet what will happen when they get to 10 or 20 firings, and I don't know what will happen if you were loading them repeatedly at 80k psi plus. If I get to 10 or 12 firings on all of them I'll probably throw them all away and start over. Will probably be ready for a new barrel at that point anyway.

If you go on the long range hunting forum there is a thread there with a few people loading them converted to 308, 6.5CM, and 260 AI. I'm not a member there but Ive read through it and I don't see anyone reporting what Bartlien is purporting will happen.
 
Instead of sending pressures to the moon, why not just load light for caliber bullets? Ryan at Vortex Optics runs a suppressed 16" Tikka (I think) in .308 but loads 130gr and is getting close to 3000fps if I recall the video correctly.

Video if anyone is interested.

Yup.

Light for caliber bullets fly like wiffle balls... fast up front, but shed speed like it's their job.
 
When I started working up loads for the hybrid cases my intention was to only run them at about max load velocities for brass cases and the only benefit would be that they are cheap and the primer pockets won't go loose. If you just buy Lapua or Alpha small primer brass you could do that too, but they are expensive and I was curious about trying something new. the case capacity and found they are 2 or 3 grains more capacity than brass cases so I started loading them at max load book charge weights and compared chronograph numbers to load books and quick load. After a couple loadings I wasn't seeing any brass growth or loosening of the joint so I incrementally increased the charge loads comparing velocity with quick load till I got up to what quick load estimates to be about 70-75k psi. I'm delighted with how it shoots and the velocities I'm getting so I'm not planning to keep going past where I'm at but may experiment with different powders and bullet weights.
 
I'm interested in what this technology would do as applied to an 8mm through .416 modern sniper cartridge, or the good old .50 M2. It's probably already in the prototype testing stage, or possibly deployed and field testing. The .338 LM had a number of kills before any of us ever read about it!
 
Kinda what others have said I’m not actually terribly interested in a 7mm Magnum, and I’m definitely not on the short barrel bandwagon. But if they can get the “Peak Alloy” to work well it opens up a world of possibilities. Lawyers would never go for it but it could be a handloaders dream. I have a .30-06 Savage 110 I bought when I was in Jr. High. Wouldn’t it be fun to peak alloy an ‘06 or any other legacy cartridge and get magnum performance out of it once in awhile just for funsies?
