Remember, 223’s are marginal and not recommend for deer. Bullet design and terminal ballistics have nothing to do with it. A 45gr SP is exactly the same as a 50gr mono, which is exactly the same as a 77gr TMK.
Last year was mostly a 6.5 deal, but years prior. Impacts from nearly 3,000fps to just over 1,800. None were “80 pound swampier Louisiana whitetails”.
And that there, is why I generally avoid bone whenever possible and try to put the bullet tight behind the shoulder. I'll take the occasional 50 yards runner, and VERY occasionally 100 yard+ runner to not have to deal with those bone fragments and that nasty, gritty bone marrow in the shoulder meat.
