Bear with me I'm not up on this, but are you saying the same breech plug that fits my 50 cal encore would also fit after reboring to 54 cal.?Yes.
My Encore breech plug is 11/16” diameter (0.6875”) with a minor of (0.625”).
You can measure the face diameter of your existing plug to confirm.
Thank youYes sir.
My GReen Mountain 54-120 uses the same plug as my other Knights.
