6mm Creedmoor vs. 6.5mm Creedmoor

Is there any significant difference between 6mm Creedmoor and 6.5mm Creedmoor?

Which one would you choose for a new bolt-action rifle and why?

One is unobtanium the other will replace 308 in virtually all capacities in the next 3 years

I doubt it will fully replace .308 wholesale but it is catching on which is very good. Might have some staying power.

I mean, aside from the practical factors.

How does it compare to .308 in terms of recoil, for instance?

I'm sure 6.5mm Cred. is superior in many ways, but even if it's better in every single one there's just a LOT of .308 rifles and machine guns out there already, it being the standard heavy cartridge for NATO since the 1950s and all. 6.5mm isn't going to just come in and replace everything, especially in 3 years.

The real question is will it augment .308, slowly (and I mean like 20+ year timescale) phase it out or come and go as a fad? Only time will tell.

I'm just looking for a new bolt-action rifle and I see a lot of them in .308 Win and 6.5mm Creedmoor, as well as 6mm Creedmoor. So I wanted to know if there is any reason to use those

.308 if you are very worried about ammunition availability in the distant future. Even if it gets eclipsed ammo will always be around for it as legacy support (like it is for .30-06 and .45-70 for instance) because so many guns chambered in it are out in the wild.
6.5mm if you are sufficiently sold on the benefits and are willing to take the risk. It's a popular cartridge now with growing popularity and a promising future but it could go like .41 AE so that's a risk you take. Not a huge problem if you hand-load of course (it uses .308 as a parent case and 6.5mm projectiles are well established).
6mm seems to have not really caught on much, so I'd give it a miss unless you are exceptionally keen on it and willing to go full wildcat.

6.5-7mm is the sweetspot for low recoil and good ballistics.

Heavy ass shit like .338 and up is for when you don't give a fuck about recoil, cost or whatever.

6mm is for when you're looking for accuracy out to medium-long and would rather have even less recoil than the 6.5 to 7mm stuff and don't care/need the better external ballistics they can provide.

6.5 will have less recoil than a 308.

Imo as a huge fan and owner of both, if you're hunting under 500 yards, 308 is a better option. The line up of factory hunting ammo is probably the largest selection out of any caliber, and its effectiveness is undisputed.

If you're just punching holes on targets, metal plates, and going for longer precision shots 6.5 is a better option. In my area match grade 6.5 is a little cheaper than 308, and there's tons of great options until you start loading your own.

If you're a prepper, get yourself a goddamn ar10 and an upper in each caliber.

>but user what about hunting longer ranges?
If you're asking about what caliber to go with, you're probably not a good enough shot to be taking ethical shots at 500+ yards. Also imho if you're hunting outside of 500 yards you need to look at bigger calibers (300 win mag, 6.5-300 weatherby)

Let the shitposting and crying commence.

6mm in .243 has been a damn good dual purpose gun for 60 years. Shoots a heavy 100gr bullet at 300fps that'a great up to mule deer (some use it on Elk, but let's not go down that road). Also shoots 60grain varmint rounds at 4000fps in case you need to disintergrate varmings with a MPBR of nearly 300y. I read that some PRS guys use 6mm as well.

6.5 is definately a more dedicated medium game round. Assuming I could actually call in Elk, I'd trust a 140gr bullet to make it out the farside of the animal's chest than I would a 100gr.

I guess I'll go for a 6mm Creedmoor then, since I am just target shooting

> Also imho if you're hunting outside of 500 yards you need to look at bigger calibers (300 win mag, 6.5-300 weatherby)
Amen. Who the fuck wants to walk half a kilometer to start on a blood trail running down a ravine.

Do you reload?

No, i don't

Then why would you get a 6mm creedmoor?

Because I don't like the recoil of the .308 Win.

Do you think 6.5mm Creedmoor is better?

If you don't reload, yes.

6cm has flatter trajectories, higher velocities, and lighter recoil than 6.5cm, making 6cm a better competition round for PRS. 6mm PPC is the hot new shit right now.

There's 6mm Dasher, 6XC, .243, 6.5 Creed, 6mm Creed, 6.5x467L, 6x47L, .260, and others that are associated with the PRS world. 30 cals are dead in that realm. I thought 6mm PPC was a benchrest round.

How far are you shooting paper at? Not being a shitbag but if its under 300 yards and your area is calm I would go 223 everytime

My range right now is 150m, but they're extending to 500m in 2020, so I would like to be able to shoot at that distance.

Right now I have an AR15 in .223, which is decent enough

Im always a fan of having a shitload of guns so I would be lookin at a nicer bolt 223 now and maybe a 6.5 in 2020 but that's me, kek.

You're right. Everything 6mm is hot. Fast and flat is the current dogma. 6 creedmoor, 6AR, 6PPC, 6XC, 6 Dasher and 6 SAUM are all in the mix and winning matches. But i think 6.5 creedmoor has real legs and is here to stay.

Do you have any recommendations for a nice .223 bolt action gun?

I was looking at the Ruger Precision Rifle in .223, but they don't sell those anymore

Savage makes some great ones, (model 12 f/tr is stupid good) weatherby does as well. Depending on budget you could always go with a custom action and build, but only if you know a good smith.

Look into 6.5 grendel and .224 Valkyrie. 6.5g is a proprietary round owned by alexander arms, so support and options are limited, but lots of data and rifle options exist. .224v is 2018's hot new meme, and lots of companies are pushing barrels, bullets and rifles for it. I personally don't care for either because i don't like shooting gas guns.

Barrel life

6.5 because of the barrel life.

I only shoot manual action guns so I have no interest in either caliber.

Who has a factory offering in 6mm creedmore? And why would 6 creed be better than 243 win?

If recoil is your big concern, just get a .243 Win. I haven't seen seen 6.0 CM in stores here yet.

If you have a chance to shoot 6.5 CM and verify recoil won't be an issue, it's possible that it's price will eventually drop below .243 Win and the barrel will last longer due to not being as over-bored a cartridge.

>I only shoot manual action guns
good, you grew up. Welcome to the adult table.

The 12 F/TR looks decent. I will have to look at my local gunstore if it's available.

My big problem is that I live in Austria and it's not so easy to come by good firearms

>Is there any significant difference between 6mm Creedmoor and 6.5mm Creedmoor?
this applies across the board, but when you compare smaller caliber rounds with larger ones fired out of the same case/charge you will find that at any given bullet weight the smaller caliber will have higher ballistic coefficient longer range capability and better sectional density which are all good things, but you will have higher barrel wear as a result, which makes choosing the right caliber a balancing act of performance to longevity.
>tl;dr
>small caliber = better ballistics at a given weight
>large caliber = better barrel wear at a given weight

If you're shooting enough to burn out barrels, then barrels become a consumable component and your argument becomes moot. If you don't shoot enough to burn out barrels, then high velocity rounds are likely not for you.

>fast and flat
7mm-08, anyone?

No one will ever love you. 7x57 has forever tarnished 7mm due to the Krauts.

>If you're shooting enough to burn out barrels, then barrels become a consumable component
True, but its not a moot point. Burning out your barrel at 1000 rounds (6mm) vs 2500 (6.5mm) vs 5000+ (308) is significant, someone might not burn out a 308 or 6.5 but will go through a couple 6mm barrels. On top of that is the fact that the military will gravitate to the rounds which give better barrel life and that ammunition will be more available for less money.
Obviously though it is up to the individual to choose what they want, 6mm is definitely better if barrel wear is acceptable, especially if the person is going to hand load anyway where bullet availability is a non issue.

6.5 creedmore is a meme
6.5x47 lapua is a meme
.260 remington is a meme
6.5x55 is not a meme

I wonder who could be behind this post?

Im not the recoil shy user im the one suggesting a bolt in 223 or 6.5

And this post.

Kek, ive always been that way. Hate ars, hate aks, hate everything semi auto.

I think you meant to write 5.56. It will replace 5.56 in the next three years. Wounding enemy soldiers isn't very ethical.

Unless you can replace every single 5.56 cartridge with a 6.5CM 1-to-1 when you fill up a C-5, the US military will never allow that to happen, wounding patterns be damned.

.41AE got supplanted by .40 S&W. And no, it does not use .308 as a parent case. It uses .30 TC as a parent case. .260 Remington is .308 win necked down to 6.5.

Which is quite a ironic, because wasn't .30tc supposed to give equivalent velocity to .30-06 but out of a short action?

7.62 NATO is still the superior high volume/machine gun round. Barrel life is shorter and heat buildup is faster on the 6.5 Creedmoor.

For low volume shooting though, 6.5 CM outclasses 308 in most every respect. But we've known that for years about the 6.5 caliber, it's hardly news.

Exactly. It's solving something that only a fudd would consider a problem. Most people don't give a fuck about the 100 fps difference.

>replace 308

Not a chance in hell.

>the other will replace 308 in virtually all capacities in the next 3 years
LOL'd. Let me know how replacing a NATO cartridge will go down.
Fucking retard.

Hornady bet so hard on that cartridge too, buying up the tooling. Remington sitting on their fucking ass with .260 gave them an opening, and boy did they make it work.

Remington fucked up with the 260

You can't load truly high BC projectiles (which are very long) and fit them into an AR-10 mag. 6.5 CM shortened the case length so you can load VLD projectiles.

>Rustington making good bussiness decions or products.

>ethics during wartime
Guess how I can tell you're a soiboy?

Eh. 143s are long enough for most. Not sure you could cut a .308 case in such a way to manage Berger's anyway.
