I'm old and I shoot a stout load so I have a muzzle break and i use a wad which complicates muzzle loading. I havnt tried this but I don't see a problem. A breech plug that is easily removed is required. Measure where the base of the bullet rests when loaded with your particular powder load. Cut your powder funnel tube off to seat the bullet from the breech when it rests against the end of the barrel. Pour powder in and reinstall the breech plug. I would probably place the bullet a little long and use the ramrod to be safe, but this step may not be necessary.
