I just picked up a 10.5" bbl from tp555 a couple of weeks ago. This is a SBR AR build for my wife. I'd been using a 6.8spc loaded w/150gr SP's & AA#9 for subs, but cycling was so-so and I was key holing pretty badly at 100yrds. I decided I'd pick up a whisper and give it a shot for her instead. I'm just waiting on a stamp so I can starting building her can. Until then, I'll just use my HVT and see what I can come up with.
