Im loading my 338whisper case with 11.7 grains of blue dot powder. these are just 3 cases im loading up over and over. i have 3 reloads with h4427 powder and 4 with the blue dot. the primers are still tight. primers still have rounded edges. and just a dent no flow back or raising of the primer. With the blue dot but it looks like i might be getting a very very light shinny spot on the case head. wouldnt the the pockets or primers show signs first. they did on all my other guns.
