I have to go with Bolts Rock. After trying various powders, Varget has become my go-to with BL-C(2) close behind. Both drive 55 gr pills in my loads consistently accurate in my guns.
BL-C2 has worked for me over 30 years firing anything from 52gr to 69gr but you give up some velocity above 62gr bullets. Varget has worked the past few years with every match bullet from 52gr to 80gr.
Not sure what the OP means by BLC being messy in the press.
