I have found that bevel based bullets(mostly Magnus cast) give me more trouble than flat base or slightly chamfered cast bullets.
As long as the bullet diameter is at least .005" larger than the cylinder mouth diameter and you do not exceed the pressure limits for the bullet alloy, there should be minimal if any, leading.
