New 7mm cartridge from Federal

[liber]

Probably their HK91 (military version G3) and HK93. 7.62 and 5.56. I had an HK91. Awesome rifle. It had fluted chamber to assist in pressure for blowback. It sucked for sizing cases. Not sure if they still do it.
Don't know why I told you that. Just sparks a memory I guess

Ah, just use a bit of water and bump that shoulder back with a popsicle stick! LOL

I haven't heard a reply on the ceramic case 277 Fury. Maybe it was non pertinent. It might not have been 277 Fury. CRS Steel case head and brass body. 6.8x51 I guess.
Not on topic. I know. What's new.

I don't remember hearing about Fury ceramic, the cases I remember were hybrid with steel for the head and brass the rest. But, AFAIK, there was never any rounds that actually reached 80,000 psi.

Now with this Federal announcement they're using some nickel alloy for the cases, which I don't see for sale on their website. But there's a lot of shooters reviewing this cartridge, so they seem to be pushing it. Still remains to be seen if the non-brass cases stick in the chamber and/or cause clickers. That is a common problem on the 6.5 PRC, and possibly others, but the Alex Wheeler 2 mods seem to fix that. Also, clickers seem to happen mostly with high pressure, so the average PRC shooter shouldn't see that, where Bench Rest will be taking it to extreme pressure. I guess time will tell!

Here is my take. I know that Federal claims the cases are reloadable, but the malleability necessary for decent reloading doesn't really play nice with 80k+ pressures. It also reduces your margin to catastrophic failure, unless the gun manufacturers start beefing up actions and barrel tenons, which is kind of counter to why we build short rifles in the first place.

I wonder what the price of ammo is. I'll guess probably enough to make it a flop.

I'm betting on the Flop...steel cases... probably only be one source for those! And once again...what's the gain...a few 100 fps....oh well something new to talk about!

I could be wrong but I thought I saw a ceramic case application about 3 years ago. Maybe military. I thought the 6.6x51/277 Furry. I could be way off so I'll drop it.

Probably have to buy new titanium dies or something...

It could be, that I don't know for certain, but you bring up a good point that I don't think has been mentioned. The 277 Fury was rumored to be adopted by the military, and what about the 7mm Backcountry? It certainly doesn't have a very military type name, heh?

My contractor shoots a 300 RUM, that's a heck of a cartridge...been around for a long time but the 300 PRC just barely beats it out, ballistics wise.

He's shot everything in the west with it, bears, elk, deer, et al, he doesn't like pig hunting. He doesn't like tongue either, so I get dibbs on tongue, and he often shares his game with me!

I don't know if I want a 7mm that is speedy. I am going 7STW. Kinda feels like we're going to reinvent the wheel soon. Just my opinion

Yeah, I wasn't planning on 6.5 PRC either, but somehow it happened...

I have been planning to build a 6.5 Creedmoor and have most all of the parts, and I have 4 action blanks, but the 6.5CM was the first I've been wanting to build. Well, I'm just getting my new shop setup, so it's not really operational, and I have 2 short action rem 700 blanks, one round and one tactical, and I have 2 bolts that fit either one. One is standard bolt face and one is magnum bolt face, but both of the bolts are short action bolts. The tactical blank could build a long action, even a lapua 338LM, but I would need to get a bolt. And honestly, there is no real reason as I have another bolt/blank set for a 375 CheyTac. I don't need that for hunting, unless I was to go to Africa and even then a smaller caliber could take most everything I would want to hunt...(famous last words).

There's not a lot of 6.5mm barrels around, mine is 1.250" straight, 1:8 twist, so I'm looking to see if I can trade it for a short action stock to use for a hunting rifle. I can get another barrel later, it seems like a better bargaining position. I digress, not trying to get banned from here, I was gonna post in the trade forum, but it told me I can without being a supporting member. Moderator, please remove this if it violates the LRH forum.

The 277 Fury isn't the same cartridge as the new Federal round . The 300 PRC doesn't beat out the 300 RUM. The 30 Nosler and 300 PRC would be a better comparison. The 308 Norma an 300 Win Mag not far behind. Only thec30-378 has more gas than 300 RUM.

I think it depends on what you're looking for. As far a recoil, 300 PRC definitely wins. Very close in velocity that I don't think either would matter.

My contractor shoots 150 grain TTSXs with H4381, I think he started from the Hodgdon site for TSXs and worked up his own load. Barnes does show the H4381SC at 3400 fps in the latest data, but he's been shooting this cartridge for years. I know the 150 is kinda small, but that's what he likes to shoot. He's taken an Elk at 780 yards in Idaho a year or two back...(it tasted good! ) That's clipping along though...I don't have anything that would reach that kind of speed.

Also, when I was looking, the 300 PRC uses less powder, another plus. I think that would be good for anything in NA, and most likely Africa, aside from Elephant. I bet given a magazine, the 300 PRC could take down a mammoth sized elephant, but I think the same thing about the 300 RUM.

Because of this is seems to make sense that if someone didn't have a RUM, a PRC makes a lot of sense over the RUM, but I see no reason anyone with a RUM would be enticed to change to PRC other than anxiety. LOL

EDIT: one point to RUM, it fits in a standard long action as far as I know, where the PRC is kind of extended, similar to an AICS mag. And that translates to more stocks in general, where the PRC could be limited. Looking at the case you would think otherwise, but when seeing a bullet seated in them, it becomes obvious. Could be hard finding a stock to fit the 300 PRC. Trying to be objective here...because I let a stock dictate what I'm using for 6.5 PRC.

Ammo is priced pretty fair compared to other fast 7mm's.

I don't see all the hate; it's reloadable, it's fast, a lot of good guns are being chambered in it.

Does it really do anything that something else doesn't already do? No. But it's innovative and a step towards the future.

The RUM uses a magnum action in Rem 700. its longer than a "long" action and has a bigger bolt face. The PRC is a shorter case and has less case capacity so I can't it having more velocity/M.E..
I could care less who wins the recoil contest. You stated the PRC "barely" beats it out. Never happen. The PRC is shorter in length than the RUM so your your theory on action mags and stocks Is bogus also. I have no anxiety over my 300 RUM. Been shooting and reloading for them since 1999. Long before the wonderful 300 PRC. I get 3482 fps. With a 180 Hammer and 3275 with a 215 Berger. Both not max. I could push them both but with the groups I get I don't need to. I ran Barnes TSX and TTSX 180 gr. for a long time in my factory barrel at 3360 fps. 3/8 in. Groups. 150 TSX at 3630 fps.
Maybe you should do some more research on your PRC compared to RUM.

Being from Kommiefornia does "Iiber" mean liberal ? If not I'd change it. Just saying ...
No offense Adam32+P

The "extra steps" required to reload is intriguing. Wonder what is involved there? I'll be hitting the Utah outdoor expo pretty soon. Maybe I can get some answers then.
