Fire forming brass with Sierra 175 gr soft points using IMR 4831 it is slow at 2675 fps but shoots .6 groups at 100.
Also have shot the Bergers 180 using H1000 shooting in the 2850fps. I only have a pound of n565 so not going to burn it up trying to get over 3000 fps. I will stick with H 1000...

I have a bear hunt this fall in North Carolina and I have been working on a load with Sierra Soft Points 175 gr.
I had a 8lb jug of IMR 4831 laying around and decided to try. To my surprise the powder has been shot very
well in temps from 55 degrees to 75 degrees in GA.
IMR 4831 54.5 gr...
