Has anyone loaded up any WC-850 surplus powder . I recently came into 16 lbs of this powder along with 8 lbs of WC-846 .
From the powder chart I found on this site it says to use the load data for H-380 for the WC-850 and BL-C2 load data for the WC-846.
The only concern I have is with the note about it is associated with chamber ringing . I thought chamber ringing was associated with small powder charges and a filler in 45/70 cases.
