At a time when I used my 243 on deer. I preferred Remington 80-gr. PSP. Fast, flat shooting, and hard hitting out of my Ruger 77. Never cared to use anyone's store bought 100 gr bullet ammo. Stuff didn't seem to work out for me in what I expected of it. (had to track deer a fair distance too often when shot with those 100 gr bullets) 80-85 gr. bullets on the other hand. Those deer succumbed to there wound within 20 yards or less usually. (rib shot most often made by me)
