I have bought a lee 155gr. mold (.312").

Has anyone worked up a subsonic load for this? I have read about the dangers of SEE etc, and also a few threads saying that the case capacity is similar to a 44 mag.

To save me reinventing the wheel, has anyone worked up an accurate subsonic load?

I guess 2400 would be a good powder, or titegroup with a filler of some sort (cotton wool)?

I have no clue how fast it would push a 155 gr bullet, but hodgdon/IMR Trailboss is a fantastic low pressure powder. I'm pushing 160 gr gas checked hardcast with 18 gr in a 30-06.

Thanks for that.

Does anyone know where I could find some load data to start with?

I'm trying to stay under 1,000 FPS.

You might want to email Hogdon about the Trailboss tomorrow they will let you know if it is safe and about what the load will be. They have been helpful to me in the past many times.
