Is one better than the other? Seems Lapua has better ballistics but Creedmor is more popular. Why is that?
Barrel life better in the Creedmor maybe?
I've never had an issue getting 6.5x47 brass. .260 brass has been hard to find, and from what I've read 6.5CM is very hard to find.
The 6.5x47 uses the smaller PPC flash hole, so you'd have to get a different tool if you cared enough to ream and clean them.
I'm not sure if the 6.5x47 would feed in a semi, but as most of you know the .260 and CM feed in the modern hunter.
I've read that because of the better , stronger brass that the 6.5 Lapua uses.This gives a slight edge to the 6.5 Lapua as you can load them a bit hotter, thereby having more velocity.
I just read an article by demigod, who compared the 6.5 CM,6.5 Lapua and .260 rem.
He ended up choosing the .260 , but did say that all three are virtually the same.
I'm running 34.5gr of h4350 @ 2835fps and I got 8 reloads out of my last batch of brass and I don't aneal.
