Yep, 64gr is an oddball weight. Typical .223 bullet weights are 55, 60, 62, 68, 69, 70, 72, 75 and 77gr.

.223 is the caliber size or bore diameter of the lands, .224 is the actual bullet diameter and exactly what you want to use for .223 / 5.56mm. Bullets need to be just oversize or they won't seal the bore
