I’m never one to complain about a pass through. But I will never forego an internal grenade in the name of an exit. FMJ’s will largely exit, but zero grenade/damage (relative to an ELDM/X or SST or TMK or Berger). I want chunky, soupy insides, and if a projectile happens to exit, so be it. But I won’t trade some terminal damage to get an exit (IE I’ll never trade to a Barnes TTSX to get an exit in lieu of getting the tissue damage from a Hornady ELDX).
EDIT: Clarifying, I don’t need an exit. I don’t care. But if it happens, whoop-de-doo. I’m more concerned with tissue damage. It’s why I use ELDM’s/X’s and not bonded projectiles or monos.
