7mm Federal Backcountry

[Old Navy]

If your saying that a case that doesn’t fully fire form at 80,000 psi, will be difficult to resize with a conventional die, it makes sense.

Those cases did not not fireform.

 

[Herzo]

It would appear that conventional brass cases could be formed out of 30-06 brass should someone wish to have "reduced " loads for practice or other activities. A modified 7mm neck sizing die could suffice.

A rifle working at that pressure is a disaster waiting to happen. The thing will not tolerate any kind of failure. A gas leak by a faulty primer will be horrible. A handheld Columbia gas leak.

 

[nakneker]

Yet another fad to deal with. How many more cartridges do we really need.

This really isn’t about a new cartridge as much as it is about a new case/alloy. I get what you’re saying but I think this case may actually change things. There’s a ton of info on it for those who are interested. I wrote it off at first but the more I watch and read about it the more intrigued I am. It’s the case that is new thing here..

Brass is the weak link in high pressure now you take the brass out of the equation now whats the weak link?
Action? Barrel?
Reloaders over pressure stuff all the time and some factory ammo so what happens when there's 90,000- 100,000 psi?

Well the 6.5 prc filled a gap, there was no high performance short action “magnum” 6.5. I wonder if a 6.5 wsm would have taken off if introduced earlier?
And 80,000 psi is a much higher pressure increase than standard maximum of 65ksi. So its kinda not reinventing the wheel imo.

More i think of it, it does seem to be advantageous. Sure a hotrodded 7 wsm, 7prc, or 28 nosler could see great performance in a 20-24” barrel thats ideal in the back country. Hell even 16.5-18” for more suppressor friendly lengths, you could still kill game a long range. But it def wouldnt be as efficient. And thinner case for an extra round or two seems cool. Has merits.
My biggest concern is reloading and how expensive it will be, price of alloy casings? Forming/resizing process, any special equipment? How many reloads?

Actually there is and was a better High Performance 6.5. Call it what you want, GA Precision named it 6.5 Gap/4S or 6.5 Saum/Rsaum. Take your pick. It leaves a PRC in the dust and is a super accurate round. Hornady makes the Gap/4S brass available thru GA Precision or ADG 6.5 Saum brass. PRC with 130 gr = 3100 fps, Gap with 130 gr + 3300 fps. Kills like the hammer of Thor.

Look at the barrel length on authors rifle, in American Rifleman magazine. . 26" old school. No suppressor.

Again, as discussed throughout this thread in other responses, it was not commercial mainstream over the counter available to the masses…aka saami i guess. Maybe its reached that status now idk but i never seen it in gun shops or ammo on shelf. I had forgotten about the 6.5 rem mag but that was dead decades ago. 6.5-284 was perfect but didnt seem to gather the attention it deserved. But might be considered long action? Thats what the PRC did, jumped on the 6.5 popularity high bc train and took advantage of the long range shooting/hunting craze to where we are now.

From a third party business perspective it seems like an overinvested project than no one was bold enough to kill soon enough. They kept testing this for 6 years and spent so much money on it that they decided to launch the cartrdige no matter what. It's clearly agency problem.
Market was not expecting this cartridge, There are other cartridges out there which do the job and are reloadable. It's not a competition cartridge.
It's a hunter's cartridge. Do hunters really need it? Time will tell.

My suppressor.

The article states it is a 20" #2 contour barrel.

edit: Going to the Weatherby site and looking up the tech specs say its a 20" barrel with a 2" muzzle brake for an overall length of 22". It is threaded 1/2-28 for a suppressor.

 

[FrankG]

I will await the die specs and experience in resizing the cases.
Thanks.

Reloadable is possible... is it going to be easy.... I'll say no. From what I'm hearing... neck tension / consistencies are going to be the biggest issue.

I wouldn't hold your breath on dies and reloading it at this time.

Brass is the weak link in high pressure now you take the brass out of the equation now whats the weak link?
Action? Barrel?
Reloaders over pressure stuff all the time and some factory ammo so what happens when there's 90,000- 100,000 psi?

This right here is well said! Take note everyone!

The higher the pressure and we are losing safety margins in the barrel steel and actions etc...

I’m guessing the weak link will be the primer and people without a bushed firing pin will not be happy.

I've played with several PRC's that guys spent a ton of money on and tried to get them to shoot, a couple did with the correct load. A couple got re-barreled and a couple were "close enough" for who bought them. Unimpressed at best. There is commercial 6.5 Saum ammo available thru Prime.

lm glad i read this cause i always considered the 6.5 prc just a 6.5 saum with a different name. i was just gonna order a 6.5 prc reamer. now ill check a little more before I do. the cases are almost identical so Im thinking the performance of my handloads would be about the same. thanks

Performance is not even really close, I have no issue getting a safe 3300 fps out of a 22 inch barrel with great accuracy. I use 4350 burn rate double base powder. The Saum/Gap holds 5-6 grs more powder. Ballistically, the PRC is a 270. 130gr @ 3100 fps. ADG runs 6.5 Saum brass a couple times a year and a lot of places stock it. I just got both 7 & 6.5 Saum brass from Blue Collar.

I wouldn’t reload that one.
