Depends on critter, caliber, weight, and TTSX.....except for some specific uses/cases/ weights....Barnes is overkill for deer in anything over 243,...JMO. Cup and core is plenty. I’ve yet to catch an accubond in a deer, anyway. ....but a .308 130 TTSX at over 3k is great for threading needles through treetops, and the 30-30 150 TSX thinks it’s a 300 WM.
