Velocity question on factory Hornady 73gr ELDM

[AdamRM]

Hello all, first off I would really like to thank everyone that contributes to this forum. I've been primarily a handgun shooter for the last 20 years. Do to a wrist injury I needed to find a new obsession

I've re-equiped my Colt 11.5" SBR to start leaning the basics of scoped shooting.

I don't have a chronograph yet, so I was wondering if anyone might have the velocity of factory Hornady 73gr ELDM out of a 11.5" barrel just so I can figuring what my ballistics will look like at least in general terms until I start working with my own data.

Thank you all again for the new education

Adam

25fps per inch is subtracted from the 24” factory test barrel’s listed velocity. So, I’d say 2450-2500fps?

That's the fps range I also had in my head, was curious if anybody happened to chrono that ammo in their 11.5

I greatly appreciate it
