7mm Creedmoor——-who’s in???

[High Plains]

A 7mm Creedmoor might be seen as a cartridge we don’t need. I think we have long since passed the “we need this” era and now we are deep into what we can make the market will support. Nosler sorta led the way with their cartridges based on the 404 Jeffrey and I have no idea how sales are doing ‘crept for the 28 Nosler seemingly doing the best in that department.
A 7mm Creedmoor would compete with the 7mm-08 Rem, the 284 Win, the big 7mm magnums and the short magnums. Would it work? I think so.
Discuss.

I love the 7mm, IMO the CM case is too small to really offer any major advantage over what the completely stock 7-08 delivers.....the other CMs DO offer some "improvements" over the other common cartridges (fast twist for longer bullets, and less bullet in powder space etc.)

Imo the 120-140s from the 7cm vs the 7-08 wouldnt be very interesting. The 160s could be if throated long for them.
The 180s wont have the velocity to really excell, and IMO you NEED the 180s to best the smaller CMs.
Again IMO, the 162 vs the 140-147s would effectively be a wash, UNLESS you needed/wanted the extra 20gr of bullet weight.

That doesn't mean i wouldnt buy one, i like the way the CM case looks and Its not like the 7-08 class performance is anything to sneeze at.

Too small. But the 7-6.5 PRC is doable and has been done with success.

 

[gotboostvr]

The 7mm-08 is already twisted fast enough for just about any bullet you'd want to cram in a case that size.

The 6.5 and 6 creedmoor addressed the twist and overall length concerns with the 260rem and 243Win, respectively.

The 7mm-08 dosen't have that issue, or at least not to a large an extent. There's very little blood to squeeze from that particular rock.

 

[troy fairweather]

I agree it would have the powder space and the 7-08 is just fine the way it is.

 

[Bcwitt]

I'd go the other way. 25 creed, anyone? 270 perhaps?

 

[JDeere]

7-08 can do all things I need done. Range out to 600 with 165s and hunting with 140s. I have more than one in 7-08. Personally I would not even be interested.

25 cm would pretty much be a 250-3000ai and should be nice, even the 270 I don't think it has enough for 130s or heavier.

Or a .796 BC 180 gr @ 2600 fps.

 

[jmr40]

IMO the 7-08 IS the 7 Creedmoor.

^this.

Gotta get up into 170+ class bullets in 7mm to exceed the 140-150 class 6.5’s, and then we have to push the shoulder back farther on the case to fit the ogives ahead of the neck, so we lose even more powder capacity.

7-08AI does pretty fantastic with the mid weight bullets, but it gives up some BC to the slippery 6.5’s.

 

[3% outdoorsman]

Would do 7 saw before any of them.
Alpha makes brass and no fire forming needed.
Run a 308 through 7saw die and your your done if you want to go that route with no fire forming needed also.same performance as 7-08ai but no fire forming

There are .277 Dia. projos down to 90 gr. @ least. Mabey 100/110 ?

Ya but there pretty much a flying brick,

If I was looking for a new hunting cartridge, 7mm08 would be at or near the top of my list, If a custom rig I would put the AI ahead of the standard chamber, I think the 08 case has better capacity than the Creedmoor case for the 7MM and up calibers.

 

[CarJunkieLS1]

The 7mm08 is IMO what the .308 should've been all along. To me it does all I've ever asked it to do. I even use my hunting loads at the target range too. Shot it as far 835 yards and done well. Mostly 500yds at most now.

I won't shoot at live animals that far as I have roughly 400 yards as my max, but for the most part if I can see it I can hit it.

The 7-08 and 7-08 AI existing makes the 7mmCM idea a moot point. If you need more in that size action the 7WSM or better yet a 270WSM necked up to 7mm even better.

The Creedmoor case design really hits the sweet spot in the 6mm to 6.5mm diameter adding the proper twist barrel of course.

 

[Okie_Poke]

I agree with others that a 7 Creedmoor doesn’t really make sense. But guessing what cartridge the folks at Hornady are going to release next is entertaining speculation. My guess the 25 Creedmoor. I’m also curious if they try a 338 prc or something to cater to the ELR crowd. Think a scaled up 300 prc case designed around their 300 grain a-tip or the 285 ELDM or maybe a new ELDM. Im not sure what other gap exists in their cartridge line at this point, other than the 25. I don’t think they’ll touch 27 with a ten-foot pole, but I’ve been wrong before.

 

[1948CJ2A]

I always wanted 25-08 to become a thing. I read about the 25 Souper wildcat but it never really caught on. I love quarter-bore calibers almost as much as 7mms.

 

[LoonWulf]

25CM is kinda a thing, when my 6.5 burns out, it or the 6 are my most likely tries...... If I don't, just stick with the 6.5.

I feel the 130-140s are about the perfect weight for them CM case to drive.

 

[High Plains]

The 27 Nosler is the latest, perhaps last of the small caliber cartridges to carry the Nosler name. Why was it last? I think it is a combination of few bullet weight varieties that can compete with the .264” and .284” calibers with high ballistic coefficients and market demand. Let’s face it, there is not a wide selection of bullet weights in .27 caliber. Virtually the same goes for the .25 cal bullets.
Let none of this be misconstrued as “only” high BC bullets are worth using. Noooooo way, at least for me because ordinary lead core bullets of 1960s design have dropped plenty of deer for me and my friends, despite hunting on the High Plains where a 300 yard shot is typical.
I doubt a 257 or 277 Creedmoor sees the light of day in a production rifle but I’ve been wrong before.

 

[Legionnaire]

I'm content with the 7mm-08. A 7/6.5 PRC might appeal to some, but I'd jump straight to the 7 PRC.

I wish they had done a full length 300prc for the 7......but what they did actually makes the most sense in that caliber i think.

I think they should have went longer with the 7 to, it's already needs a long action. Then they could really say it's faster then the 7rm, some of the shooting comps have speed restrictions so maybe that's why and a little better barrel life.

 

[someguy2800]

I am interested in doing a 7mm SAW, but it offers so little difference between 6.5cm and 308 that I can't justify putting money or time to the idea until I wear out my 2 6.5cm barrels. I can't think of a compelling reason for a 7cm.

 

[WisBorn]

I look at what a 7mm CM may do for the other cartridges?
Some of the bullets that were developed as part of the 6.5 & 6 cm are available for the other 6.5 & 6 cartridges. Yes, you may not be able to take full advantage of the ones for the fastest twist bullets, but technology usually helps the old cartridges as new cartridges are introduced.

I like the new bullets that are being loaded for the 7rm in factory offerings. How many of those bullets would be available if it wasn't for the 7 prc and even the 7mm RUM???
