I highly suggest not using borebutter on inlines like this that use sabots. What I suggest is, you shoot it at the range, clean it with simply green or simular, store with some good oil barrel down, and before hunting, shoot ya a fouling shot.

In fact, this is the reason I swab every shot. I may get better accuracy not swabbing every shot, but its consistent and before hunting season, I take to the range and ensure its sighted in, go home and clean the breech plug without disassebling the entire rifle, swab the barrel with TC number 13, and take hunting. After the week season, totally clean.
