No way a double lung shot lasts that long. The lungs collapse and she can no longer breath and she is also bleeding to death internally. All of my double lungs I' ve seen or heard the deer fall over within 60-70 yards. We' ve gotta see those pictures!!!!

She had to have one lung to last that long.

A double lung will die withing seconds of being hit. High entrance and exit wounds will prevent blood from hitting the ground. Another thing that can block a hole is if the lung hit was made with the foreleg back. This will quite frequently block a hole very efficently. Generally, the DL hit deer will drown in its own blood . . . very quickly.

Sounds like a single lung hit to me. And I have had experience with them(unfortunately). I would swear a couple of shots were good double lung hits , but upon careful inspection I only caught one lung .
I have learned to wait an hour before looking because of this, even when I feel 100% that I made a great shot. - Even when I hear them go down.

I also think it sounds like a single lung hit and
tend to agree with others comments- deer hit
through both lungs just don' t live that long. No
matter how she bedded down it' s not going to
keep air in her lungs if a 1 1/2" BH just went
through them.

I' ve seen what appeared to be perfect ' double
lung' hits...turn out to be not what it appeared.
When both lungs are taken out, that animal is
" dead on it' s feet" and rarely travels
far.

The important thing is you recovered her[:-].

The first half your story made me wonder if I wrote it!!
I took a doe last year with a sidewinder and she half jump kicked, stumbled around for about 20 yards and then made a death leap into the brush where I recovered her. All within view except where she landed!! It was a beautiful sight to behold!!

I have to agree with the others, it had to have been only a single lung hit. Double lunged deer do not live that long.
