FWIW...I sell extreme duty industrial lubricants for a living. Food grade lubricants typically do not possess the extreme anti-wear properties (such as molybdenum) that non-food grade lubes have. FG lubes are made so that they can be consumed in a small quantity if some gets on a edible product. They have extremely limited EP additives.
I can't fit a 14-ounce can in my range bag.
This would typically not be a aerosol or liquid can. 14 ounce is the standard for a grease cartridge that fits in a standard grease gun.
Oil is typically the preferred lubricant IF it will stay in place. Grease is simply solidified oil with some anti-wear additives added. The amount and type vary greatly depending upon the manufacturer. Moly is an exceptional EP (extreme pressure) additive, but is quite expensive per pound. Many manufacturers add little or no moly. Just because several greases are listed as "moly" also does mean that they are equal. Moly can be as little as 1/10th of 1% and still be listed. Our greases typically have 11%. That makes a world of difference.
Also, the amount of RO (rust and oxidation) additive can vary significantly within different oils. Hydraulic oils are typically either AW (anti-wear) or RO (rust and oxidation) blended. You never see an ad for WD-40 that touts their anti oxidation properties. They say "for anything that sticks or squeaks". I guess if your gun sticks or squeaks, that's fine. In 50+ years of shooting I can't remember one of my guns that sticks or squeaks.
Lubriplate was bought out (for the naming rights) by one of major manufacturers. I consider them one of the poorest lubes on the market currently.
I would look for something that has strong anti-wear characteristics and also R/O properties. For the typical person, CLP (cleans/lubricates/protects) comes to mind. I would assume this is most shooter's objective. Lubricate and retard oxidation (rust).
For me, I sell a PTFE teflon based product that has incredible anti-oxidation properties. AFAIK, PTFE has the lowest coefficient of friction of any product available. That's what I use.
YMMV
