Home Forums Hunting & Shooting Muzzleloaders Rusty Bore?

Finding an old Knight slotted breech plug removal tool isn’t easy or cheap. Harbor Freight to the rescue. The nipple was stuck so I ground a spare chisel and worked the breech plug loose. Having soaked it for a few days in Kroil helped I’m sure.


I finally got a clear look down the barrel. It’s still not pretty after a brass brush (that’s chunks of rust stuck to the interior) so it’s back soaking in Evaporust.

I’ll keep after it and see what transpires.

I plan to order a new style breech plug and musket nipple to match my other Bighorn and for the added benefit of easier removal. Pulling that rusty breech plug was a relief!
