My family had terrible experiences with the 243 shooting 100gr cup and core bullets but no more deer needing multiple shots or lost when I started loading 100gr Nosler Partitions. It really doesn't take much to kill whitetail deer but for some reason we were jinxed and all swore we would not have another. Other than shooting heavier bullets the 257 Roberts and the 243 should be able to down deer equally but I'll have nothing to do with another 243. But I would gladly hunt with a 250 /300, 250AI or a 257 Roberts. Just doesn't make sense but I don't want any dealings with the 243.
