Petroleum jelly (Vaseline) has absolutely zero film strength and shear resistance and is a terrible hinge pin lubricant. Mixing any kind of plant oil with it would only make it worse, if that's possible. Anyone who has used break-open shotguns enough to matter would know better than to put such a concoction on the hinge area of these firearms.You continue to reveal yourself as a poseur here, Jager.

Be strong, be of good courage.
God bless America, long live the Republic.
