Has the 6mm Creedmoor much following in the UK, or is everybody just going to the 6.5CM?

Just wondering about rebarreling my 243 Heym at some point. It still shoots well. Just questioning whether 6mm CM would be better than a faster twist 243 (ie better with longer copper bullets) or just go to 6.5 CM. However I do shoot 7mm so 6.5 is really quite similar. I suppose real benefit of going to a faster twist 243 is that I don't need any form of variation etc.
 
6CM has a bit more poke than a 243 but that's about it, marginal really IMO but YMMV.

I went fast twist 243 for 107gr for convenience with dies, brass, reamer etc. Loaded for accuracy rather than speed.
 
Also you’ll have factory ammunition available in .243, which may be useful sometimes and is certainly a plus if you ever want to sell it.
 
Recently bought a 6mm CM, but yet to shoot it yet! No factory ammo availability, and besides - the licensing department managed to mess up the variation so my ammo authority is for 6.5mm not 6mm…

I have dies, brass and bullets (108gr ELD-M) ready to use. Unsure on which powder to go for yet…
 
A fast twist 243 and a 6mm CM are ballistically very similar. The big benefit is factory ammo for the 6mm CM (at least before the ammo shortage).

IMHO it's best suited for competitive shooting, but can be dual use capable in a hunting role.

Both are barrel burners though...which in the UK, should be a major factor (since prefits seemed to be limited in the UK by proofing laws).
 
Barrel burner. Let’s put it in the magnum range of a fried barrel at 1100 shots.

Say I use 100 shots on barrel break in, load development and scoping.

My other thousand shots. I could shoot 20 foxes or dear per week for a year. Or I could shoot 2 foxes or deer per week for 10 years.

Barrel burning is a term bandied around by people who have never shot a barrel out. Me included.

I’ll be happy if I need to get my 6mm Creed rebarreled in 10 years.

Hmmm...okay.

For some though, it is a term that is real. For example, I'm on my 3rd 6.5CM barrel on my AI. The two previous barrels died around the 3000rd mark (2950 on one, and 3100-3200 on the other).

Some people who bandie the term "barrel burner", have actually shot out barrels before. It's also why when buying a 6.5CM barrel, I order bullets in bulk for the life of the barrel (3k in the case of a 6.5CM barrel). Less load work up, and more competitive shooting, with periodic checks on the labradar for velocity shift.

If used only for hunting, then yes (obviously), you'd likely not shoot the barrel out quickly. But the 6mm CM was designed for competition, and some people do both. So barrel life can be a concern by some in the UK, and certainly many in the US (where we have a lot more matches and hunting opportunities).

Matches yes, hunting opportunities no. There’s a lot denser wildlife population over here and a lot less hunters. I know of 10 guys locally (less than 15 miles) who all shoot in excess of 50 deer a year. My best year on wild and free ranging deer is 62 animals back in 2017.

@Heym SR20 forgive me but it very much reads as though you’ve answered your own question in your initial post. Unless you plain just fancy a 6cm, which is of course a good enough reason. You’d just be making a rod for your own back in changing calibre.
 
I moved from .243 win to 6 creed. If you reload, in my opinion I’d do it. I’ve yet to find fault with the 6 creed. The factory 108 match ammo from Hornady shoots one hole groups in my rifle.

I’m contemplating a second 6 creed as a stalking rifle with a 22” barrel. The current creed has a 26” barrel.
 
@Ronin has just delivered a Sako 85 with a 20” 6 creedmoor barrel.

I went with the 6mm creedmoor over a .243 because I have whidden 6.5 creedmoor FL bushing dies that’s I can use.

Also it is a more efficient round than the .243 in the shorter barrel.

Having lived in the UK, I'm not sure I'd agree with that assessment. While in the US we are limited in how much game we can take by game regulations/seasons, there are a lot more hunters, and a lot more game to hunt here in the US than the UK IME. In fact, I was stunned by how...sterile...the fauna was in the UK. Nowhere near the diversity (or density) of game as in the US. Which makes sense when you consider the sheer difference in size of our two countries, plus the fact that we haven't been killing stuff off in our country for anywhere near as long as what has been done in the UK.

Case in point: While I only bag one deer a year (mainly due to time and location), there have been years where I have shot well over 600 prairie dogs in just one week, never mind that when deer hunting, it was a decision of which deer of the 60+ I was looking at, that I shot. Never mind dove, quail, pheasant, wild pig (5 varieties in my state alone), duck, geese, coyotes, bobcats, fox, turkey, elk, bear, bighorn sheep, pronghorn antelope, javelina, tree squirrels, rabbits etc...

Then add all the imported exotics (which in many states are not limited by law on bag limits and seasons) like axis deer, auhdad, and others, and you have a much denser wildlife population in the US. Hell, there's more whitetail deer in this country now, than when Columbus landed back in 1492. And then there's the declining hunter population here as well, but again, we're a country of 330M people. Sometimes I think people forget that the UK is under 94 thousand square miles big (with ~67M people), and the US is 3.7 million square miles. Which do you think is going to have a more dense wildlife population? Especially when so much of our wilderness is part of the government park system, and many parts of it are largely untouched and in pretty hospitable/temperate places (Yellowstone, Glacier, Gran Tetons, and those are just some of the big, well known ones).

I mean, come on, the state of Montana is almost 50% larger than the entire UK.

Fair enough @MarinePMI I’ll bite,
U.K. deer density roughly 8 per sq km
US deer density roughly 2.5 per sq km
US deer population 25 million, and active hunters 15 million, meaning 1.6 deer at any one time per hunter.
U.K. deer population is 2 million ( a 1000 year high) and there are 535,000 registered fac holders. If we assume they all stalk deer, which they don’t, it would still give us 3.7 deer to every U.K. fac holder at any one time.

So I’ll stand by my point that we do have not only a denser population of deer to shoot, but that the fewer hunters in the U.K. will likely kill more deer per head than a hunter in the US.
I’m not wanting to start anything, I’m incredibly envious of the opportunities American hunters have. And yes your map does show how little this country is, if only it was less crowded.
 
Thanks gentlemen for the input. I do like the 243 as a nice light rifle. I am trying the Peregrine 100gn and they shoot well in my old rifle, and so far on the only deer I have shot, they work well. I am totally convinced the 80gn non toxic bullets work very well on UK deer and other deer around the world. But we have a silly restriction here in Scotland with a min of 100gn bullet.

I suspect I will still be pondering whether or not to rebarrel in a few years time!!
 
@Ronin has just delivered a Sako 85 with a 20” 6 creedmoor barrel.

Also it is a more efficient round than the .243 in the shorter barrel.

I’d be interested to know what ammo you’re using and what velocities you’re getting. I looked at the same link when deciding to go with a 26” barrel for a vermin/target rifle.
