Anyone out there loading subsonics with the Hornady 255gr Sub-X in a 7.62x39 yet?

I picked up a cheap 16” Ruger ranch rifle in 7.62x39 just for the purpose of shooting subsonics for Rockchucks in the cherry and pear orchards. The bullets just arrived, I have a pile of Starline brass. I have no clue where to start. Hornady told me they currently had no load data for the combo at the time. Plan on running it with my 36M suppressor.

All the best things in life, live on the other side off fear.

The true eye sees not the despair of its victims, only the elegance of equilibrium. It's a demonstration of superior judgment.
