If you are planning on using the TC Naturalube as over-ball grease, it will work fine, BUT...it will also blow all over the gun, making it as messy as a 3 year old's high chair and slippery as a greased eel to hold onto. I highly recommend over powder wads. You can get these in either lubed or dry. For general shooting, lubed are preferred but some people like to leave a BP revolver loaded and the lube can work it's way into the powder and cause a squib load or misfire if left for days or weeks at a time, in which case you should use the dry ones. You can also make your own using Durofelt and a wad punch if you choose to go that route. Buffalo Arms carries the wad punch.
Or...stick with the lube.
