So far I have just used my VihtaVuori manual as a guide. Since it only has VV powders and I can only buy VV powders, it is serving its purpose well.
I went for N135 or N140 for two reasons. One was the velocity. For that Sierra bullet both those powders seem to generate decent velocity. At starting loads the N135 gives 2558fps and N140 2548fps. The other option would be N150 at 2576fps
In the burnrate chart that comes in the manual N135 is in 71st place and N140 in 78th. By comparison, Reloader 12 is in 69th and reloader 15 in 80th. N150 sits in 85th position.
You cannot wake someone who is pretending to sleep. Stop pretending. Wake up.
