I bought a 243 for my son for the light recoil. I have been loading 100gr. speer GS, 100gr. hornady spire point and round nose that I had on the shelf and they did ok, but it just didn't have the punch to my liking. So I got some 85gr. barnes tsx for it and that made the difference. My son shot a doe at 120yards and the bullet entered in the front shoulder, went through, broke 3 ribs, exited and broke the other leg, deer ran 30 yards and fell. These bullets shoot better that any of the other ones I have put through it. I was not very sure about a 85gr. bullet for deer, but the barnes bullet is almost the same length as the 100gr. bullets I have been using. They are impressive in my opinion and perform well with better penetration.
