Thread: 223 question

Has anyone chronied the 223 Hornady Training ammo through a 22" barrel?
If no one has, would I be alright guessing it would be about 3150ish fps?

I have with the steel case stuff, though I doubt the brass is much if any different.
I won't be home for a few days but I'll check my notes for you then

This ammo through my 24" only chronyed to be 3100fps.

@smidey

I have though @Spudattack chrony.
I think I posted a thread about it, search chronograph Hornady 223.

I can't ATM, on my phone

That seems pretty slow... What twist rate?

Factory Hornady (brass case) 55gr SP #80255
20" barrel, 1 in 8
3084 fps average (Magnetospeed)

my average was 3151 from my 1:8 22" barrel, interesting. I like the ammo, still very accurate

Mine was from a 21.5" long, 1/8" twist with a Chrony at around 8ft away. Saying it, my speed is at "G1" and yours at "G0", maybe it is the difference.
Sorry I can't be more precise but the velocities are printed as you can see and I can't change that, also the group say how precise it was, the flyers is ALL on me.

My post wasn't referenced to yours in anyway PERRISCICABA.
Just providing additional data on the Hornady load.

I have my 223 @ the Gsmith at the moment. I will beable to give you 17.5" plus suppressor speeds later
