I have a Robinson Arms XCR-L with uppers in both 223 & 6.8 SPC from what I understand RA is working on releasing a 6mmX45 barrel.

Being that this is the round that I feel the 223 should have been introduced as all along I will be picking up the barrel as soon as it is available...

So a big thank you for that link to the pdf load data file it will definitely come in handy...
