Sorry for a bit of a resurrection here.
Just wanted to add that I have been running a TTD set at 8oz for ~1krds in my carbon and have had zero issues with reliability or safety.
Have seen a lot of people concerned about this, just want to clear it up. Seems to me it was perhaps more of a problem with earlier rifles.
Nice shooting btw. Currently contemplating what chassis to throw mine in and leaning MPA was well.
