Hello everyone first post here so sorry if this is in the wrong place but I recently picked up an original model 1836 made by R.Johnson it’s definitely all original the bore looks very good action works great on half **** and full **** the nipple still has very thick walls and looks good the negative is the powder burns around the nipple area I was wondering if it’s a good idea to shoot this (I don’t like lookers) and possibly value does it have a removable beech plug and should I even bother trying to get it out I looked it over really good and seems safe to me but this is my first original it appears to be .54 cal I can add more pictures later during the week when I pick it up unfortunately I bought it in NJ and they classify it as a firearm so I had to ship it to my PA ffl
