I know a lot of people who do use it with sabots to get them to slide in easier and it works really well for them... but that is one of the ways that I think might bewrong - if you cake anything with BB it might come back and bite you.
Another group of people have reacted to the the tobacco stain they see on occasion, BB causes leaching, it forces (leaches) old powder residue trapped in the lands grooves of a gun. We all think we clean really well but it is awful hard to get it all especially down in the chamber area where the powder is driven into the walls with pressure and heat. Back in the day when I was using a copper based BP grease - it was impossible to get it all out of the chamber area as heat and pressure had driven it into the pores.
Again BC, I really think it is the application process that a lot of us screw up. Course that is just my thought. The processworks for me and doesn't for others and that is OK.
