500straight.500 Nitro Express heavy (very heavy) cast bullets loads?
I have recently purchased some 970-grain cast bullets for my .500 NE. However, I have no idea where to start with a load for these bullets. I have been reloading 550-grain cast bullets for awhile with good results using 40-60 grains of AA5744. I do not know what to use for a starting load with the 970-grain bullets? Does anyone have any ideas? Thanks.
