In my experience...nope...hunt it...if its a good area they will return...About 10 years ago I shot a 8 point in the lungs with CoreLokt...he ran perhaps 25 yards...and fell under the tree I was sitting in...I was a smoker at that time...so I lit one up...relaxing, enjoying life...heard a noise behind me...looked around...dang if there wasn't a 9 point with his nose to the blood trail...not 25 yards from my tree stand....While I was watching him....he just dropped...Hit the ground....CoreLokt through the neck put him down...
