Try these guys http://www.precisionvarminting.com.au/products.html

They are bringing in alpha munitions brass in 6xc with small primer pockets and other target shooting / PRS calibers. Supposed to be very good quality

Is your chamber cut for a 6XC or 6XCII chamber? My understanding is the Alpha brass may not work so well in a 6XC chamber. David Tubb recommends Norma or Peterson for the 6XC. I bought a stack of Norma from Magnum Sports a while back so might be worth a call.
I can say that with a basic 6XC chamber I’ve experienced the stiff bolt closure that I was warned may be an issue with Norma brass. I picked up one of Tubbs FLS dies (which is a small base die) and that seems to have solved the problem.

Thanks BATattack,

Bullyeye,
Your spot on with the chambers, and brass variants.. Im fairly confident the reamer I have is a 6mmxc not 6mmxc II... The reamer has only been used once and i have been told that norma 6mmxc brass was fine and had no extraction issues... Ill keep looking around..

This afternoon it got the better of me to try something with the dies at home and im fairly confident that this brass will work fine, just takes abit more work... (Will need to be inside neck reamed and neck turned.)
Made from some factory fired 308 win brass that was laying around, last step was ran through a 6mmxc FL die... I will do the same to a few different cases (6.5 creedmoor 243/260) just to see how they extract/handle pressures etc..

L to R
308 win FL
First form die (used a 6mmbr body die) sized shoulder to within .015"
Then through a 6mm xc FL and trim to length

Your other option is run neck up Lapua 22-250 brass and fireform 6XC brass from it.

Has anyone tried lapua 22-250 brass in their 6xc... How did it compare to norma/peterson 6mm xc brass?

Think you have to neck up and push the shoulder back leaving some horrible looking mushroomed brass which does fire form out. After going down the Dasher path before I think I’d find an option not requiring that amount of work...just my opinion. Original 6XC was made for brass formed from 22-250 so it obviously can work.

As for Norma brass in a 6XC chamber, I had no issues for the first couple of firings then had VERY tight brass on closing the bolt. Thought it was a headspace issue but no amount of shoulder bump fixed the problem. Sticky brass seems to have been solved by a small base die. Just my experience which at this point isn’t extensive but seems to run true with what I’ve read on the www.

Wal86, I used 22-250 Lap brass to make XC, it's slightly different but works quite well. Use a 308W die to push down the shoulder so it just chambers then fire form. A great article on 6mm.com some time ago described it all . It referred to penis head brass after the 308 die was used. Anyway it's simple to use on new Lap brass. fireforming it shoots quite well with a jammed 105gn VLD. I've never had problems with Norma XC or 22-250 brass made into XC. Your call.

I have a Tubb2000 rifle with barrels for both 6XC and 308. I have shot 6XC for a number of years and get good results using Berger VLD 115 grain projectiles in Norma 6XC cases with 38.0 grains of A2209 powder. 6xc cases are expensive and often hard to come by. I have tried fire forming 22-250 cases. This works but the cases are real ugly until fire formed and the results with the first load are pretty bad. A cheap option is to start with a Winchester 308 case and chop about 3 mm off the neck then using a 7mm-08 bump die I bump the neck down to the level required for 6xc. Then I full length resize the case using my Tubb 6xc full length resizing die. With practice you can get a very good 6xc case out of this process without having to anneal or heat treat the brass. Since you can pick up once fired factory Winchester brass at our range for virtually nothing these cases make a very cheap alternative to 6xc brass which currently seems to cost more than $200 per hundred. You need to use Winchester brass rather than Lapua or other good quality brass because the Winchester brass has a thinner neck and shoulder. This means that you don't have to ream the new neck. If you use Lapua brass this is necessary. Also the thinner brass can be worked carefully without annealing.
Hope this helps.
