With all of these factors below in Lapuas favor why would they make Creedmoor brass?
The 6.5x47 is more accurate then the 6.5 Creedmoor.
I once considered the Creedmoor and asked this same question on many forums. What I asked was if anyone who has both a Creedmoor and a 47L, of their two guns which was more accurate. The answer was 100% unanimously the 47L so I went with the 47L.
Since then other things have come up that have convinced me further of the virtues of the 47L vs Creedmoor.
In this article the author of rifle shooter.com states very plainly that the 47L is more accurate.

Another major thing to think about is the life of the brass. Lapua's last 25 reloads at worst case scenario. While Creedmoor guys struggle to get 10 reloads and most only get 5-7. That means the brass ages fast and it changes from shot to shot a lot more then the Lapua does. This I believe is a major reason for the greater accuracy of the 47L.
I will include a nice graph for you by Precisionrifleblog.com As can be seen in this graph if you shoot a 47L you are much more likely to place or win in PRS. As you can see the numbers for both the 6mm and 6.5mm version are better for the 47L then the Creedmoor. By the way a smaller number is better in this graph.
Next and probably LARGEST REASON the 47L is more accurate is that the 47L has set a hug slough of world records. The Creedmoor has yet to produce ANY and don't anyone say that is because no on is shooting it. There are a ton of people shooting it thanks to excellent marketing. But once again it has yet to produce any winning results.
Next there is that primer pocket. The USA Palma team has proven that small primers produce a smaller ES. And that gives the 47L an edge in accuracy.

Then there is the cost. At first you would think the CM is cheeper to shoot right? NO it is not. Think of it this way.
A batch of Lapua brass costs $105 for 100. Creedmoor costs $66 for a batch of 100. Noe divide both of those $ by the number of reloads you get out of each. The Creedmoor you are guaranteed to get at least 5 reloads.... well ok lets be nice and say 10 even though practically no one does. That works out to be $0.066 ea. While the Lapua gets at worst 25 reloads that works out to be $0.042 ea reload. That is an astounding 50% difference in cost with the Lapua coming out to be much cheaper to shoot. And we are not even connoting that Small primers are cheaper and the 47L needs less powder to get the same performance as the CM.
Lastly remember that these to cartridges are basically Balistic twins. Both do the same thing ballistically.
I see only one reason to by a Creedmoor. That is factory ammo. If you do not reload then get a Creedmoor but if you reload then it would be stupid to get anything other then a 47L.
