The odds of shooting out a .223 bolt action without really working at is pretty slim. At least for hunting/ recreational accuracy.
Bulk wise 68 and 75 hornady bthps are pretty good. If the 73 eldm was offered in bulk it would be my choice for most and fit magazines better. There are 69 & 77 grain bthps offered by most manufacturers, Lapua and Sierra are slightly more consistent for accuracy but most would do for punch paper and ringing steel. Unfortunately most of the heavy bthps are not consistent when shooting critters.
Lots of lighter bullets being suggested, I wouldn't bother fmjs but hornady's 55 grain soft point (2266 if you want an item number) often available in bulk and a good plinking and critter bullet. I wouldn't worry about too fast a twist.
