I would make another suggestion also - if the BP is the standard BP I would make a real effort to find a Lehigh breech plug with a removable vent liner or contact Bestill Creations and get one of Jeff's breech plugs that will/can be built to fit your rifle and the primer you choose to use.


Also, if you do go to BH you will probably need to use a wad to seal the bore and keep the heat off the bottom of the bullet. BH and T7 will melt the bottom of the bullet.
