300 Win Mag load for Browning BAR II?
Hello, I am trying to set up a load for my browning BAR 300 winchester magnum auto loader. I have tried remmington factory ammunition which grouped better than anything I have loaded so far. I tried hornady acubond 165 grain bullets and tried IMR 4350, Reloader 22, A3100 powders and have not been able to come up with a load that works. I am going to try hornady 165 grain interlock bullets next, but not sure where to start on powders. If anyone knows this rifle and has a good load already.... even if it is a larger bullet 180 gr will work too. Thank you for any info.
