You have alot of good advice here. My 99F 308 needs the small base dies when using brass fired in a different rifle. I use IMR3031 and don't exceed 40.5 grains with 150 grain Hornady JSP's. I don't think that you will need 165 grain bullets even for Elk. I got a 610 lb (dressed) cow moose at 120 yards with 150 grain Hornadys. She took two before she realized the seriousness of her condition. Take good care of that 99. Mike
