No one. It's counter-productive. You can find 50-55 grain flat base bullets, (they are superior for 100 yards) but not 68-70. 68-70 is for long range, they would not bother making them flat based. TO test your rifle at short range (out to 200) use 50, 53 or 55 gr flat base bullets. They are cheaper (less materials and easier to make) and inherently more accurate at that range. (they also create slightly less recoil, as if it matters in .223)
