6XC OR 6 Creedmoor

[Milo 2.0]

Did they elaborate on some of the "whys" of that decision?

Thanks,

George

Some of this experience, I've been around my share of 6 creeds, owned one, and some conjecture, but I think necking the case down results in a lack of efficiency. If you run the faster powders that work in 6.5, now you have no barrel life. If you opt for a slower powder, now you get into a dead zone of suitable powders, and incomplete burns the order of the day. And it does not have the capacity to run slow powders like H1000.
I have friends that are trying to download the case for prs style shooting, (fast strings), it's not really working, too much carbon buildup, esp carbon rings.
Not a fair comparison, but take the 6.5x284, far from an efficient case itself, necked down to 6mm, yeah it worked, all it is was something to talk about.
I Pulled my 6 creed apart, I'm done with the case, but I pulled my barrel because my sizing die out of spec, was not buying new die, fixing brass, or buying new brass, it was just the easiest route

Yup, if you want trouble free go 6XC if you want 6.5 get a 260

The ones that had 6xc's before 6 Creedmor said the XC was easier to load for, had better barrel life, and easier to keep in tune. The one that had 6.5 and went to 6 Creedmor said that he just bought into the hype and had already ordered another 6.5 barrel. WD

The beauty of the 6XC is it appears to be basically developed for N160. So, the barrel life should be excellent with that powder.

Lapua making 6mm creedmoor brass by the end of the year. This is a no brainer IMO. Not to mention you're starting to see 6mm creedmoor factory ammo on the market and even factory rifles chambered in this caliber. You'll never see that with the 6XC.

I learned quite some time ago...the hard way...."never say never."

You are quite right. There is a "Factory" working on producing rifles in 6xc as we speak. Will they pull it off?? Time will tell. WD

blaser already have released 6xc

Reading threads like this makes me want to buy a new barrel, even though I don't need to at all.

For you 6XC shooters using Norma brass and bushing dies.....what size for .002 NT?

Both of my 6mm creeds have been super easy to load for. 1st one is still going strong with 1800rds on it and the second is at 500 with zero issue's. Both shoot practically the same load (4451 or rl23) with the exception of bullet choice as one has used only 105 and the other 115. I have no experience with xc but can't really see it being any easier.

Blaser rifles use a modular system with owner-operation QD barrel (and if needed, magazine) changes, so 'releasing a rifle in any particular calibre' simply means that the company has produced a stock of barrels in that calibre / chambered for that cartridge. The number of barrels made in a batch might be in the 10s, 100s, or ,000s depending on expected demand. The cost and risk of investing in a low demand cartridge are modest - the hammer forging mandrel, barrel forging machine downtime for set-up/breakdown before and after a run, and the inventory cost of the barrels alone should they sit on a shelf for years only being slowly used up. That's how come Blaser R models are also one of the tiny handful (possibly the only) factory rifles also listed in 6.5X47mm Lapua.

When an order is received for a new complete rifle, the factory staff simply select the appropriate bits from the store, assemble them, check headspace, and send the completed item off to the proof-house. (An EU legal requirement.) As many owners use the DIY switch calibre facility, the order may be for a standalone barrel as an alternative. The assembly bit takes a few minutes only. Manufacturing a conventional rifle with a threaded barrel takes more time and work and once made it ties up the inventory cost of the complete rifle (or maybe just a barrelled action) until an order is received.

So, having Blaser list a cartridge doesn't necessarily signal any opening of floodgates with others following. Because Blaser can do this so easily and relatively cheaply though, how quickly it starts to list something is a good indicator of demand being received from dealers and its distributors in other countries. I believe it has taken several years for 6XC to be adopted whereas the Creedmoors were picked up rather more quickly.

Not really what I was trying to convey at all, I know it can work. I guess I should have went in depth by saying if you run a powder in the 4451 burn rate, you now have a less than ideal case fill, and 4-5 gr of unusable capacity. If you are not utilizing the capacity of the case, it's efficiency drops, IMO

A 243 will shoot 105s all the way up to almost 3400 with N160, and you can shoot the lower nodes to the same or even better accuracy. I am really kind of stunned no one shoots it. Works for Dan Whidden, and considering how people love to copy so and so whoever won this or that, people not copying Whidden is really kind of perplexing. Maybe it the cost of VV 160N powder... No one uses it. It is one of the neatest powders i have ever tried in my life. It runs cooler than H1000, is so clean it barely leave anything in the bore and is just stupid accurate from the bottom node to the top.

A couple in our club shoot the 243 competitively and win matches. I shoot it and have shot a 1.7 inch group at 540 yds using Hornady 105 hpbt. That's in a Savage PTA and criterion barrel.

That's funny, there is no one that I know that started out with a 6.5 creedmoor and transitioned to the 6mm version that would ever go back. Shoot a 140 hybrid at say 2870 fps, or the same BC bullet in 6mm at 3100fps. No brainer.
With less recoil.

Which 6mm bullet has the same bc as a 140 hybrid? Berger shows .311 for the 140 Hybrid. The 115 VLD is only .289 and pushing that to 3100 is going to be a bit warm.

 

[AckleymanII]

For me, the 6 XC is very, very easy to tune, 8T- H4350 with 107 Sierra's in one barrel and 115g Dtac's in the other barrel which is a 7T.

Hohn, You probably will not get a reply from him. Thread is a couple years old and if I remember correctly he got banned from this site.

A 110 SMK is .613 and the 110 A tip Hornady is .604..... jim
