Since there has already been a fair amount of thread drift, I'll add this note on SBE's. Hunting bud uses one exclusively for our forays hunting geese on cut over corn fields. One morning his became a non-functioning non-shot. Nothing could be seen to be wrong. He had to use a borrowed gun that morning. Back at the hotel I dismantled it trying to ascertain what had happened. Finally realized that he must have sat the gun down in the corn stubble w/the bolt open when we were getting comfortable [we were shooting lay out blinds] and picked up a minuscule bit of corn stalk or chaff and it was essentially invisible due to the black moly grease where the rotating bolt's head went to battery, but it was enough to keep it from going all the way home. It wasn't much, size or thickness wise, perhaps not even .125" x .005", but it was enough to keep the bolt from going fully to battery and made the gun inoperative. I only found it and realized what it was after wiping all of the grease out w/a combination of bent cotton swabs and toothpicks, when it came out on one of them. His gun functioned just fine afterwards.

On double gun lubricants, I like grease on the hinge pin and action's nose where the forearm fits against it. And prefer any of the synthetic oils like 'Minuteman Hi-tech gun oil, tw25 &c. favored by the 'run & gun' crowd for other places like locks, triggers, ejectors. I wipe them down w/a sheep skin sprayed w/Corrosion X most of the time, but have Eezox as well. Absolute best bore and plastic cleaner [from wads] I know of is Quick-Shot Bore Cleaner. Its no longer being made and you do not want to get any of it on the wood's finish. It was sold in aerosol cans. I was very fortunate to buy two cases [12 cans in a case] of it shortly before they went out of business, giving the first case away to shooting friends as Christmas presents and retaining the second. I'll be very sorry when the last can is gone & I'm getting close, but having to stop shooting for some time due to the Wuhan virus has delayed its consumption. Ed's Red does the job too as will MC-#7 firearms bore cleaner from Shooter's Choice, but its not as quick or as convenient.
I'm of the opinion that the most important thing is keeping the gun clean and freshly lubricated, more so than what exact product you are using. I've used Lubri-Plate white #105 grease, Super Lube, Military grade turbine oil and extreme low temp lubricants, Rem-oil [both with & without the 'rust preventive'], Kreighoff & Perazzi lubricants, Moly grease and others at one time or another. I also experienced a SS S&W revolver have the cylinder freeze up that had been stored for a long time w/WD-40 as the protective lubricant. More WD-40 loosened it up, but after that experience cleaned it all out and went back w/Corrosion-X and have never looked back. Had that revolver been used periodically, it might not have stuck like it did. It wasn't and it did. Just saying.
