6.5 Creedmoor Peak

[El Jason]

The new Proof rifling might be unique enough that they die in a different manner, but my guess is they’ll wear out faster with 80ksi loads than 62ksi ones just like the rest. Time will tell.

Physics don’t lie. I don’t know how they couldn’t wear out faster.

A .308 version would be pretty cool, but there’s no free lunch and I’m sure it would recoil just like any other .30 that pushes 180s at 2900-3000 fps. Still a cool idea though.

I’d also be surprised to see it happen as they don’t want Remington pump actions and savage 99s exploding left and right.

Some pretty smart guy on another forum said maybe not for the Ruger No. 1 either (in 6.5 CM). I wasn't going to do it anyway as my wife is recoil sensitive, and doesn't need the extra performance at the range she shoots.

There is a long thread on the Hammer site discussing the nas3 case in .308 and the handloading of it. mtmuley

Most people will still never wear a barrel out though

 

[Big Sky Guy]

What do folks think are likelihood this carries into straight-walled cartridges and pistol cartridges? Specifically thinking of 350 Legend and 9mm.

I absolutely agree with this.

 

[mtmuley]

I absolutely agree with this.

But need barrels that don't wear out quickly. mtmuley

This was a much smarter marketing move by Federal than creating a new cartridge that requires a new rifle or barrel. They dont care about rifle or barrel sales. How many owners of 6.5c are just going to buy a box or two to try? A ton more than buy new rifles. Tons of shooters keep the same rifle even though new "better" ones come out all time. I'll be interested in buying some if they do this treatment to a cartridge I already shoot, but I am way to invested to jump on every new trend. I appreciate them trying to innovate for shooters like me.

That’s a little surprising, considering people load the .45-70 up to .458 win mag pressures in the No. 1.

I agree, the #1’s are a pretty strong action. I do think they specifically advised against something like the CVA scouts and probably the older H&Rs.

I remember reading something from one of the developers of the number 1 saying that they tried to blow it up but were unsuccessful. It was on the Internet so it has to be true.

You know, I thought that too, but the guy I quoted is pretty smart. If I want to borrow her rifle maybe I'll ask Paul Hampton, who customized it. I don't care about recoil.

I think this concept is interesting. It certainly gives a cartridge much more versatility without having to go out and buy another rifle.

Or perhaps going heavy for caliber and not giving up velocity.

Interestingly, I built a .308 with a 16.5” barrel for a dedicated silencer setup. Compared to the original 24” barrel the rifle came with, I’m giving up some 200 fps. Now, the deer out to 300 yards don’t really care…but if I wanted hunt longer ranges (backpack sheep or whatever) and needed to get that velocity back, this idea is pretty cool.

On the other hand, it also means not needing to buy another rifle. So where’s the fun in that?

I'd think if you're compairing to a standard 6.5CM it would burn a barrel out faster purly based on pushing it 300fps faster. But to Carls/Forkys point you're getting magnum (6.5 PRC) performance out of a standard cartridge so your powder efficiency seems like it is much better. So two 6.5 barrels, one magnum (PRC) vs standard (CM) you should theoretically get less powder erosion. Especially when considering the trend to cut barrels down to 18-20". I'd imagine it's easier on barrels/suppressors than equivalent length barrels in 6.5 PRC?

IDK, i'm very intrigued based on the versatility you could have in 1 gun with endless/cheap ammo options.

Anyone have real world experience? Im interest in velocities/barrel length/group size and bullet information.

130gr. Terminal Ascents leaving ~28-2900 out of an 18" barrel sounds pretty awesome
The 156 berger eliete hunters at 27-2800 out of a 20" barrel also sound great

I'm not a hand loader so I'm trying to understand why I would ever consider a 6.5 PRC over CM if this technology actually works.

I plan to order some and chrono it out of a 16 inch and 24 inch.

Just need them to not be backordered somewhere.

Yes, powder efficiency is better. Pressure is pressure though and will accelerate wear. Less erosion than a PRC? Maybe. More than a standard CM? Almost certainly yes. Physics don’t lie.

As @Fire_9 pointed out, most folks don’t shoot enough to wear out a barrel anyway, so it’s a moot point. I’ve lost track of the number of rounds through my CM (in the thousands) and it’s still shooting just fine.

I ordered two boxes of the Fusion tipped direct from Federal when they happened to have a brief period of availability. However, I don't currently have a chrono nor am I going to have the time to actually shoot them til after hunting season, and realistically spring. I'm sure other people will chime in before then, but I'll have a chrono by then and will chip in some data on my 20" Howa superlite with an Airlock ZG7. As long as the action doesn't blow up and kill me.

 

[Forkyfinder]

Ive sort of got concerns about that myself.

To my knowledge its the only action thats scaled down like that. If it were a savage, regular howa 1500, etc - itd have the same size bolt lugs as a 6.5 prc.

I emailed LSI but i havent heard back.

I plan on trying it in my Sako 85 whenever I can find it. Sako has 6 different action sizes, scaled to specific cartridge families, with the CM being the second smallest. The case is supposed to be handling the majority of the increased pressure so shouldn't be stressing the bolt or action.

However, if you look on Weatherby's website the 7BC (also a +peak round) in the same rifle configuration (say Mark V Backcountry) with a shorter barrel weighs significantly more than a 280ai with longer barrel (which to me was part of the draw of that cartridge - lighter, shorter rifle, so I pretty much dismissed it when I found this out). I even e-mailed them because I noticed the weight discrepancy and they confirmed they use the magnum action for the 7BC, so not sure what's up with that if they were being extra safe or a long action +peak is too much for their standard lug action? Weatherby has a weird tiny but more lug system to me but you know there will be a ton of 6.5CM Weatherby's getting +peak ammo run through them . . .

 

[Forkyfinder]

The case is supposed to be handling the majority of the increased pressure so shouldn't be stressing the bolt or action.

Bolt thrust is a function of case area, pressure, and friction. So that can be true, and steel to steel has more friction than brass to steel. But Im a little skeptical of relying on friction alone to reduce that, when thats variable (oil, moisture, temp, etc) itself.

Are you sure the bolt lugs are scaled - or just the action length?
