Thread: Reloading for black powder

cowboy action loads with trail boss should be piece of wees to make up..... you want ????oz of 7s??? old rule was same VOLUME of shot as black powder..... strangely enough the starting point for trail boss in centrefire is 80% of volume of smokeless...... PERSONALLY I would run with load of same volume and see how it feels.... you shooting break open gun with no chokes...wads are surplus to requirements,circle of felt/cork is perfect,card over top of shot and nail polish it in place......it wont matter if case is only 3/4s full UNLIKE plastic hulls,you wont have wad pressure to worry about,just make sure no airspace around BP..... but you using TB so not so much of an issue.sounds like you have primers sorted.... have a look at Wingmans thread on everlasting .410 shells.....that will answer some questions and give you ideas.
