I use the Remington Express (green box) 100 gr. Pointed Soft Point Core-Lokt's in my .243. Longest shot on a deer has been about 100 yards. Took a wild pig with it at 175... Still has about 1100 ft. lbs of energy at 300 yards, so plenty of punch for deer at that range, if you do your part and punch it into the deer's lungs...
