Re: Gun Grease or Lube
I use grease (Tetra or TW25B) wherever possible; I mainly use oil (Tetra-Lube) as a rust preventative as opposed to a lubricant.
In my opinion, it is pretty hard to go wrong as long as you use a quality (TetraLube, TW25B, CLP, Slip2000, wheel bearing grease, or one of the many others out there)lubricant. If you are going to be shooting in colder temperatures, one of the modern synthetics will likely be preferred.
