Lee c312-1552r 300blk loads

Anybody use the lee 312-155gr bullets in 300blk? I have the mold coming and will size to .309. I have a bunch of cci magnum small rifle primers I'm hoping to use.

I cast the 170 grain gas checked. Still working on a load for it.

I've been loading lee 230s with 1680 and steel valley casting 220s with h110. I haven't shot any cast under 180 so I'm in new territory. Also never loaded the cci small rifle magnums but I got 2000 from a friend.
