Anyone come up with a action Cycling Subsonic Load yet

[Smokepole50]

For another data point........I loaded up some Hornady 160gr RN bullets with 14.0gr of IMR 8208 in NEW AA cases and CCI 450 mag primers. Seated the bullet around 2.4" and fired away. All 5 rounds cycled the action in my 16 inch chrome lined Saber AA upper. Velocity was a bit high at around 1200 fps so I need to back the load off a bit but it was fun and accurate. Looking forward to the next experiment.
