Negative. They were designed for a reason. The 77gr TMK is the highest BC bullet that can be loaded to standard M4 mag constraints. They also offer dramatically increased terminal performance over existing lines. The need has been there and this will become THE bullet.
that is if your trying to carry 10#'s in a 5# sack. anytime you put a bullet that size in the 223 your going to limit the power the case can hold.
your not going to be able to compare this bullet to the 77 hollowpoint. This bullet is going to have a much larger hole in the front for expansion because it holds the plastic tip. It may or may not work well at certain ranges.
