What is the most recommended 243 load for whitetail? My son, 9, will be going on his first hunt with his 243. Living and hunting western game in NM, we have never shot anything that little besides Barbary sheep which are similar in size. Usually 80-95 grn. vmax ammo is what we use. I suppose that will do for deer also. Just thought I would get some insight from those of you with it.
