6mm xc vs a 6mm creedmoor

[16tpi]

Can someone tell me which one will have the better barrel life?Velocity with 105 gr bullets, case specs differences? Would like to hear from all shooters. It's a toss up for me.

 

[22DASHER]

It's not just a toss up for you…It's a toss up for everyone! Those cartridges are so similar that in this situation the shooter will be the determining factor….not the cartridge

 

[16tpi]

Are they about the same over all? What are the ups and downs for both? I shoot a dasher now @ 1k. Looking for a little more but still want a good barrel life, and better availability in case working ease?

 

[16tpi]

Will one brass work in the other to fire form with?

Tad more case capacity with the 6 Creedmoor but not much. Hornady brass for the Creedmoor and Norma brass for the 6XC. Doubt you will see any difference in barrel life between the 2.

Thank you, how many rds life span? Not looking to hot rod. I want it to last. So what feet per second we talking about?

Hey and I want to thank you guy for the info, for the new guy... it is greatly appreciated!!

Much better brass available for the XC.

Thanks

Thanks

What about case preping, trimming, donuts... for the xc?

Both have norma brass available. Just run 6.5 creedmore through a neck sizing die and you should have it. And you'll probably have to dress the necks up a bit after that. 22 dasher is correct, your reloading and shooting will determine barrel life. I have over 1800 Rounds through 6xc barrels and they are still competitive and no firecracking at all.

FWIW, In my experience the extra work and expense to make a 6 Creedmore over a 6xc isn't worth the effort. Go with the 6xc and don't over think your choice. WD

Thanks for the information, I think the XC it is going to be... very interested in finding out more about this Round.

Now for the barrel length.. i'll be running a, Bartlein 6mm- 1.250-5"-to 1" con#12.it comes in 30",. But id like to determine the velocity and barrel length 3100 fps from 30"???

I will get 32" if need be. @ $375-485 id like to get the right length at start up. I agree some barrels run slower than others some run faster. Go long shoot to thrill, have the extra to deal with if it does shoot vel. could always use the extra for setbacks...

All the help and advice is greatly appreciative.. Anymore we be more so.

With Kind Regards, and Happy shooting

Do the XC cases have alot of case growth between firings? I have ran 22-250 and am running the 6 Dasher now, with the 22-250 after about 5 firings I started to see growth for trimming for the 22-250. I really like the Dasher and not have to trim that much. I have about 10 firings and have trimmed once to clean up and get back to length.
I know that these are to different rounds just looking for a comparative case that I have used in the past, and to what i'm getting into. More time in the field and less time reloading is the goal for me. I'm not lazy just looking for ways around to making life easier.

I would expect to see about what you're currently seeing on your 22-250. As far as your question in the previous post, to me that 31" seems like a lot and may affect what powder will work best.... depending too upon what twist rate you decide upon.

Pay the money for a VERY good gunsmith, put the best quality glass you can possibly afford, great trigger, be patient and you'll be fine with the 6xc. JME. WD

Good info on compare

If you want great barrel life out of a 6MM you should look at the 6SLR or the 6CM (Competition Match) Both are capable of 3000 rounds for barrel life and both are very accurate. They are a larger case and you can use slower burning powders so the barrel life is much longer. I just pulled my 6SLR barrel and it had over 32 or 3400 rds on it. I had it rechambered from a 6xc to a 6SLR @ around 1800rds. It was still shooting half MOA at 600yds but was starting to get unexplained flyers at longer ranges. I love my SLR.....

I have a 30" Krieger 1:7.5 twist and shoot Hbn coated DTAC 115s at 3000fps easily with 39.5 - 40.0g H4350. Most people get around 2500 - 3000 rounds before swapping out barrels. Shoots lights out at 1000yds.

Hey that sounds good!!! I read somewhere that a guy had a 1-8-7.75 gain twist rate. I shoot a 1-8, in the 6 Dasher velocity is about 2930fps.. Reloader 15 and 4064 32gr and 32.7 , with a 105 bthp honrady. also shoots 75gr serria very well. I try not to shoot those if all possible. All out of a Bartlein barrel, and Sako L579 action. Its a joy to shoot, feels like a .223 off the bench maybe less. It weighs 14lbs12oz, have a Canjar set trigger, topped with leupold rings I turned the bottom off to adapt to Sako Optic lock bases, that I put 30 minutes of angle on. Leupold 6.5-20x40LR. I dope using the hornady ballistic calculator cheat sheet. It all works very well. I also have a Wheeler scope level, x2 one is right the other has small defects that the bubble wants to stay when raise or lower the arm. Just needs to be shimmed. U.S Optics made one that clamped to the scope like the Wheeler, but it has been discontinued. :-(


Ok Ok enough of my babbling , hey tell me more about the 6XC. So the cases grow alot, Has this case been improved yet to reduce the brass working? Or did something go wrong and mess the accuracy up when you improve it? I could have a reamer made to the xc and improve it. I think id want to make the reamer to where the xc is already at a false shoulder that way one less step to forming. I learn my lesson with the dasher, and bought a second rifle small savage .243 set it back and rechambered it to fire form in. save on burning the Bartlein barrel up.

Thanks everyone for the help..

We shoot a 6 creed, great round, feeds well from magazines, even AR type rifles. Most get 2200 plus or minus accurate rounds out of your average barrel, but depends on how hot you load, light loads will get 3K out of a barrel.

One of the Hart barrels(26" 8 twist) we have can run 105s around 3200 feet with no pressure signs, 42 of H4350. Accuracy nodes in the mid 3000 and mid 3150 range. We started to load the lower node for longer barrel and brass life. Daughter, 11, was shooting 600-1000 with it no problem.
I buy the Hornady 6 creed brass from GA precision,it is good stuff, works great, have 4-5 loads on a couple of hundred of them and no primer pocket issues, brass is reasonably priced.

Hornady brass is the 6XC has a lot more going for it. Seams more accurate too from the places I am reading range reports at.
