AAC 55gr Sabre Blade velocity?

[TonyAngel]

I recently threw together an 11.5 to run as a dedicated suppressor host for a YHM Fat Cat. When I ran some PMC m855 over a Garmin chronograph I got ~2750 fps, which is about what I usually get with that ammo out of an 11.5. When I ran the 55gr Sabre Blades over the same Chronograph, I got around ~2850.

Has anyone experienced something similar? Just wondering because just shooting the stuff, I got the impression that it was a bit underpowered, because I had to open my gas block up a tick to get it to run the way I like. 2850 is pretty fast out of an 11.5.

Black Arc 53gr only get me 2900 by comparison and the Black Arc load is hot.

Sounds about right for a 11.5.

Is this current production ? .. Or an older lot ? ( purchase )

It's a current lot. I just got a case of it because it was on sale. I just thought it seemed a bit fast for an 11.5 barrel.
