6.5 Creedmoor from 6.5 X 47 Lapua or 6XC Norma?
- Thread starter reverend
- Start date
Not sure on the 6XC, but the 6.5L I think could be made to work, but the neck would end up short (proabably excessively short). Also, you'd have to neck it up, and then back down to create a false shoulder since the shoulder datum on the 6.5L is 1.405" versus the 6.5C, which is 1.520".
You'd be better off using a different parent cartridge (.308, .243, 7mm-08 or .260)...

6.5X47 will end up pretty short for the Creedmoor. Use Lapua's .22-250, neck it up and jam the bullet stout or it'll misfire. The 22-250 brass ends up short but only about .015" which isn't a big deal. I necked up to 6MM then to 6.5.
I've been running my brass from that exact process for about a month now and couldn't be happier.

From drawings I have seen, the Creedmoor is about .050 longer at the shoulder and .020 longer overall than the 6XC. The web on the Creedmoor is .471 and the 6XC Norma brass measures .469. The Creedmoor shows .459 diameter at the shoulder and measures .455 on the 6XC . I compared some of the cases at the range this weekend and visually they look the same except for the neck diameter.
Yes, my observations have been that the 6XC looks an awful lot like a 6.5CM necked down. Or maybe the 6.5CM looks like an awful lot like a 6XC necked up. Whichever.
the 6XC would entail a little less work than the 22-250 neck up I suppose. Either way you're better off than the Hornady stuff.

I'm not being flippant here, but unless you've already got a bbl. chambered for the 6.5 Creedmoor, why not just go with the 6.5x47? It's a great little cartridge - I liked it so much that I chambered an AR10 bbl. for it. Sure, the brass is expensive, but with a tuned gas port, I'm not dinging case rims with warm loads. I've also built myself three bolt rifles in 6.5x47 - a prone rifle on a BAT 3L, Eliseo RTS for XC HP, and a M700 in a tactical stock. I've found the cartridge is capable of fine accuracy, and with 139-142gr. bullets, is competitive out to 1000yds.
In hindsight, I've often wondered if the AR project wouldn't have been more economically practical if I'd gone with a 6.5XC and formed cases from 22-250 or 250 Savage. But - to a certain extent - you get what you pay for, and the Lapua 6.5x47 brass is some of the best I've ever used.

Dennis,
The Creedmoor allows greater velocity than the X47, that's why. I've heard of people pushing the 6.5X47 with 120 class bullets to 2950 FPS but that's still not even where Hornady's velocity was for the 120 class with the Creedmoor. Personally I've pushed 120 class bullets out of my Creedmoor over 3300 and that was with Hornady brass, I've gone over 3100 with 140s. The 22-250 Lapua brass, .243 Lapua and .308 Lapua is very good and Creedmoor can be made from all three, I'm sure Norma's 6XC would also be great so brass isn't something to put in juxtaposition with the Creedmoor any longer. The two cartridges run the same 473" case head, same length action, same bullets, same barrel life roughly and same accuracy - the Creemoor's just a bit faster.
The X47 Lapua's a good cartridge but that's my answer to why not the X47?
