I would read hornady specs on that first. I thought I saw a maximum fps for it .
Could damage a suppressor if it comes apart.
It was developed to shoot 900-1100 fps and expand when it finally arrives.
Going to load 100 but think they blew the design when they put a boat tail on it.
My best load is a flat base so far and have tested factory bt from several brands and loaded some.
Running 220 hornady rnfb at 1015 fps crono on a 40 degree rainy day.
Has not gone sonic in 100 degrees.
12.1 cfeblk.
@spife7980 turned me onto that load and is the most accurate sub I have found in 300blk.
