I am getting closer to finishing this build and I would like to start gathering powder and primers before it is finished so I have them on hand. What are some of the tried and true selections for this chambering shooting 80 VLD and 75 AMAX. Also what primers are you using. Take in to consideration that most of my shooting will be done when it is 30 and below and the rest when it is 85 and above. Also, does anyone know of a load manual that covers your non traditional cartridges, or is it a trial and error process starting with the non improved version? Thanks in advance.
