I'm shooting a .243 this November on Whitetail for the first time ever. My primary gun has mainly been a .30-06.
Ive taken countless shoulder shots with the 06 and anchored the deer where they stood. Is the .243, shooting 100grn Hornady, enough to still safely take a shoulder shot? I know deer have a thin shoulder but ive lost one doe to a 30/30 and I'm insanely paranoid about losing another. Years later I still let that one doe bother me.
Also, what can I look for range wise on the .243 and still remain totally effective? The longest shot would probably be 250 but I do have the possibility to take a 300yd shot. I have every confidence I can make the shot, ive been feeding lead well over 200yds with great accuracy. I was just curious about energy of the 100grn at that distance.
