I have used a 243 for the past 30 years and always use Winchester 100 gr. PSP ; I try for a rib shot,sometimes high sholder shot just depends on the angle of the deer.both will make him lay down.the ribs just behind the point of the leg will drop him or her within 50 yards or less.I havr some old road way where I hunt.I put an orange ribbon on them all at the 200 yards and 250 yards. cheap rangefinder.
this one I dropped at 180 yards Sat. evening.he came out just a few steps from my 200 yard mark.
love the 243, I have two and my wife has one.all three shoot the same ammo.Great gun for light recoil.
