Considering only the hides get used from Mink at most 'farms' it's rather nice to see some other part being used. It does make a good cold weather patch lube for most calibers, however further testing will be necessary in the 14 bore with hunting loads. Trying to remember a few minus -40 or colder hunts back in the early 90's with mink oil, seems to me that with 165gr. of 2F, it allowed some fouling buildup after a number of shots, maybe 5 or so- but my memory of that is a bit thin. I did try Crisco oil and some other vegetable oil but the Mink oil was superior. Neetsfoot oil got pretty heavy and stiff at those temps & most of it resulted in my using paper ctgs. for other than the first shot.
I used Mink oil in the .40 and .32 this year, with supurb results on target and in the barrel. Seemed even better than a water based lube for target work (trail walk) as to loading, with accuracy on par with the water based lubes, WWasher fluid or spit.
