Its all about a timely recovery and two holes make that process so much easier.

Yeah, you might get a quick kill and lots of damage with a 2" hole that didn't penetrate both sides, but if the deer goes in thick brush and there is littleor no blood trail.....well good luck in consistently finding that deer in shortorder when it is early season and 80 degrees, even if the deer only went a short distance.

You got it right Shultzy. A complete pass through is first and foremost when answering "What makes a good blood trail?"
