Can anyone give me a idea what you can expect for velocity out of a 15" barrel with a 123 grain bullet?

I'd be interested to know as well. I've been thinking hard about getting a Grendel barrel.

I had a Grendel in a custom ar15 with a 24" bbl. Not going to doll it up, I wasn't super excited at the velocities out of a long barrel. Honestly I can't remember what my hot 123's ran but I want to say in the low 2600's just to give you an idea. Fantastically accurate though!!
