What do you guys lube your C&B revolvers with?

I mean I could shoot up the 451s and then pour 454s.

What I can say is Chain fire issue starts at .451 (and likely below but .451 is a good point to call for remedy)

FWIW, I shoot some .451 just to see if there is an accuracy gain. When I do I used a lubed felt wad.

I had done some testing with felt wads ahead of the bullets, removed the wad from the chamber that indexed up for the next shot.

You could see the blast marks on the wad, but it did not go much below the surface. In my world we would call that a flame arrestor (fuel tanks and flooded cell batteries).

My take was if anything did work its way around the ball (checked the seal, it was there, not as wide as .454 of course). The Wad would snuff anything flame wise. No issues so far though the Wad goes under the bullet.

I suspect it more like .448 that you would see no seal, but .451 is a good spot to take precautions.
the only sure way to ensure a seal band is to put a ball into each chamber and then pop it out with a punch via removed the Cone.

Back in 1980 when I bought my Remington I bought at the same time a number of tubes of Navy Arms revolver sealant in yellow tubes. That stuff may not have been made in decades now. I decided to keep one unopened just to have one so it's around my house somewhere. CVA used to make something similar in black tubes. That Navy Arms lube worked well for me. Later I started using Crisco, then tried some Blue and Gray sealer. What you use does make a difference. When I first used the Blue and Gray it was at a state shoot where if I remember correctly I bought it. I shot the entire aggregate with it. Most horrible targets I ever shot. No two shots on any target were even close to one another. Instead of a pistol at 25 yards looked like I shot with a Brown Bess at 150 yards. Went back to Crisco and acceptable accuracy returned. Now whenever I use a lube it's Mink Oil since I lube rifle patches and minis with that. Most times I use Wonder Wads with no over ball sealer.
