Why would you want to? Greasy lubes are only suitable for situations where you will be leaving your gun loaded for an extended period. For daily shooting on the range or rondy, a wet patch (detergent and water is what I use) will keep you shooting all day without having to wipe out fouling every 10 shots or so. The buttered patches also tend to 'dry out' over time, so doing a stack of more than what you need for the next few days or weeks might not work out. When I wanted (a long time ago) to do a stack with bbutter, I melted the bbutter in a shallow dish on a repurposed coffee maker hot plate, then just toss the stack in; the melted lube will soak in quite quickly (squish the stack a few times to work bubbles out). Pull the stack out, and squeeze out excess liquid; let it cool, and you can peel one patch at a time off the stack. It's a pretty tidy way to carry patch in an old cap tin.
