I'm still puzzled about the bullet smoking thing.
I have shot many thousands of rounds of hard cast bullets out of my Ruger Redhawk in .44 mag. There were conventionally lubed. Smoke was not present and never even thought about.
I shoot traditional muzzle loaders a lot and use real black powder. That smokes but the 'bullets' do not.
Bullets smoke?
Nah. Somebody is making funny.
