Can someone approximate what a 16" ar-10 velocity would be?

I was trying to research the fps of an 175g FGMM coming out of a 16" D.I. AR-10 barrel. Specifically an LMT 308. I wanted to make a dope card for my rifle.

You're going to have to chrono it, but from my experience with slightly longer barrels on bolt rifles you're probably going to be somewhere in the 2520 fps range.

Here is your answer:

EDIT: Sorry, not sure if AR-10 is on this chart. I thought you wanted velocity for a .223 55 gr out of a 16'' AR barrel

2450 to 2500 there abouts, depending on what charge of powder your pushing but factory loads run around that speed.

Around 2430fps.
It's going to go transonic around 850yds so don't bother running dope cards much past 800yds.

What is the reason for 16" barrel and would 18.5" be too long for your mission?
