Lead in your barrel is due to bullet fit. Slug your barrel and cylinder throats. Next step is to use the proper bhn hardness of a bullet. Hard cast comercial bullets are not the best. Example if your bullet is a bhn of 18 that is going to need in the neighborhood of 25,000 psi to get it to expand and fill the barrel of your gun. At those pressures depending on the load it may not be obtainable for a lead bullet. Take 38 special of example that is in the area of 12 to 15,000 psi. The bullet will not expand if its a bhn of 18 so you would want a softer bullet like a bhn of 10 or 12.
