ive killed does with one lung shot, but have also "heard" they can survive on one lung.. just odd to me in all that distance it never once bedded down, i would think it would have bedded if it was in pain.. i switched to rage 2 blades this year from shuttle T locks last year, BUT i had an extra shuttle T left and in this spot i would not have a shot over 20 yards so i went with the shuttle T. they have worked awesome in the past. but not today...... my one and only experiecnce with the rage 2 blade was this year on a doe, and it made a huge entry and exit wound, and easy track...
