6xc vs 243

I have a custom 6mm Creedmoor built on a Borden Aline and I love the cartridge!
I am currently shooting the 103gr ELD X at 3180fps average with and SD of 5.5 over 20 rounds using N160 it groups amazingly. Very easy to work up a load for.

It’s laser flat with very low recoil and great on fallow, highly recommend it!

24" barrel?
 
As a current dilemma myself, I always think a 6mm/243 is an ideal size.
With this in mind, I have a howa action, PSE stock, Krieger 6mm 1-8 twist barrel.

I really appreciate the 6xc for the efficient cartridge that it is, and it's proven accuracy in competition etc.
The 243 is great for ease of ammo.
The 6 creed was designed for PRS competition, and running bullets fast.

My money is on either 243 or 6xc...
 
6mm/243 .224 is an ideal size.

My money is on either 243 or 6xc... 22 Creedmoor

Thanks for the feedback as it was an R8 6xc barrel that caught my eye and got me thinking about this option. As you say a world of choices in our sport..
Do you know the twist rate of the Blaser 6XC barrel? I went 1:8 to shoot the 108gr ELD-M. It shoots 87gr V max superbly as well. If you plan on shooting long bullets, 1:8 is the min you need I’d say. 1:7.7-7.5 would be for 110gr+ typically
 
I've shot 58gr Vmax at 4000fps and 103gr ELD-X at 3100fps out of the same rifle. Used for lamping, stalking and competition use, its a great round and very capable.

My Blaser 6xc barrel is 1:8.

Should it help, the 1:8 twist also works with the 109gr Berger. The Berger runs slightly faster than the 108gr ELDM, as in 42.5gr of RS62 gives 3095 fps with the Hornady 108 or 3118 fps with the Berger 109.

No pressure signs with small primer brass in either load. I’ve not worked past 42.5gr of RS62. RS60 or a large primer would no doubt improve velocity if need be, but I’ve had better groups and ES with lower charges.

On that note, does 6XC give a choice of primer size?
 
I have owned a 6mm XC for four years, it replaced a .243. Most off the shelf .243 rifles can't stabilise heavier bullets, with 75-80 grain being the best they can do.
Mines a Sako 85 action in a McMillan adjustable Game Scout stock, with a 22 inch Sassen barrel. Currently using 100grain game kings for everything, which it shoots like they were match ammo.
It's my 'go to' rifle and has shot all deer species apart from Sika. Absolutely love it.
 
Not really fella, personal experience.
I had a SSG69 shot lovely between 58 - 75grains, any more than that and it's group sizes really opened up. I tried most weights up to 105.
Friend had a Sako 75, exactly the same.

The eternally vague accusation that the .243 won't handle the 'heavy' bullets it was designed for.
You never hear exactly what configuration these bullets have, no detail of the make, shape, product number, nothing relevant at all.
The gullible read this sort of unqualified statement and believe it.

The Sako 75 and 85 are fitted with exactly the same barrels as the Tikka range.
Tikka models handle standard flat-based 100gr & 105gr SP beautifully.
I've worked my way through Sierra, Speer, Hornady, Geco, Remington CL, and Winchester PP now. Sierra proved the best in my Tikka, as usual.
I haven't tried the longer needle-shaped design Sierra MatchKings of 95gr upwards, or the VLD offerings because these aren't appropriate to the .243.
Do tell us exactly what bullets you're talking about. I'm more than curious.:(

I'm not looking for an argument, and really don't have the time to list every bullet/powder/primer/seating depth/cartridge make/group size combination tried over around 10 years that made me personally move away from .243.
If it works for you, then I'm happy.
I had a 6.5x55 at the same time and that could really handle a wide range of bullet weights.
 
if the build quality and barrel are the same, the only real advantage the xc has over the .243 is the case prep routine for the reloader. the .243 stretches, the xc does not. shooting the same projectile they will be equal in terms of accuracy and performance. i've had both, and shot out both and they are great cartridges. my next build for PRS comp use and park deer culling will be a fast twist .243
 
I'm not looking for an argument…

Seeing as how you’re not looking for an argument, I’ll keep it simple and state a fact: you are patently wrong and you should correct your statement to something like “my reloading skills couldn’t solve my rifle’s fussy barrel problems, and I gave up and decided to blame one of the most commercially successful and ubiquitous cartridges in the history of sporting rifles”.

I fully agree with what you’re saying, the only advantage my 6mm CM has over my .243 is the ability to reach out much farther with high BC bullets due to the fast twist. But I am curious to know why you would choose a case that needs more prep for high volume shooting like PRS competition? Is this because of the availability of the brass?

These days that is definitely a consideration - you simply cannot get hold of the brass for either the 6XC or 6mm Creedmoor here any more. All gone and none on the way.
