Can't comment on the SBE because I don't shoot Benelli anymore, but one thing I have learned about oils I can share. Be careful with the stuff out there marketed specifically for hunters. Avoid Rem Oil or what I affectionately call "Rem Glue". During cold temperatures, the viscosity of the oil will increase. After reading quite a bit on different shotgun forums, many avid shooters go with Mobil 1 Synthetic. If I remember correctly, its viscosity doesn't change until -90F. Don't ever plan on hunting in those conditions!!!..... But I can say that since I switched, I have not had a problem in temps below freezing.
Hope this is food for thought.
Best,
Steve
