Here in the US, this cartridge is called the Grinch.  You can find lots of info at both accurateshooter.com and on Bart Sauter's website.  http://bartsbullets.weebly.com/    Click on the tab named 6mm Grinch.
There are two distinct ways to approach this cartridge.  You can run an 8 twist barrel shooting the 103 to 108 grain bullets or you can run a 12 twist barrel shooting the 80 grain bullets.  Usually, the 600 yard guys are using the 8 twist barrels and the short range benchresters are utilizing the 12 twist / 80 grain combo.

I have one and it seems to me to be real close to the 6mm BRA cartridge.  As stated above, it is a nice way to take a rifle with a PPC boltface and use it for longer range.  My rifle is a legal 13.5 lb HV rifle.  It does have a bit of recoil but is it is a little less than my 13.5lb 30BR.

It will shoot well at 500 meters.  Back in September, I used it to win the Huntsville TX light gun.  You can see my best target shot with it over on the best target thread.  I was shooting Bart's 103 grain Dominators.  

The most used powders here are Varget and H4895.
