I voiced the same compaint after almost giving up on a buck shot the same place with a 130gr IL from my .270. No exit, no blood at all, just hair knocked off the far side by the impact of the bullet.
Tough bullets are one solution. Placing you shot lower so blood starts leaking out sooner is another. High shoulder shots, as some have pointed out, are another, eliminating the need for a blood trail.
If you can figure out how to shoot Muzzy broadheads out of that .243, all your bloodtrail issues will vanish. Big hole in, big hole out. Maximum carnage!
