RE: Hunting: Oil or No Oil?
I use a light sewing machine oil on my actions, to include below zero weather. I found that it works and is not costly. When I had the "opportunity" (cough cough) to carry the M16 instead of a pistol, I was pretty much stuck with break free for lube. It seemed to work. I kept a rubber over the muzzle and the dust plate up, too. Never had to use the M16 in colder than -16 degrees farenheit though. But maybe some yote hunters have and will bring us up to speed.
Many years ago my local gunshop recommended using WD40 for firearms. Over time, I discovered it had gummed up in the innards of my 45! I stripped it completely and meticulously cleaned all the parts. Went back to oil and no problem!
