I both cast and swage my own.My swaged and cast bullets for target work are aprox 5 to 6BHN.Up to 900 to 1000fps,no leading problem with the swagwd.My cast run aprox 11 to 14 BHN.I can shoot full magnum with them(some with and some without GC) and in all exept one(a recently acquired mod 629 .44Mag at 1250fps)no leading.The first thing I'll be doing is measure the throats and I'm 90% sure that's where I'll find the problem and then apply the cure to the 629.
I actually find that people shoot too hard lead in their guns.The softer lead bumps up to fit the throats of the cylinder and obturates the rushing gas to where they belong;behind the bullet.
Sometimes,too hard a bullet will only contribute to leading by not bumping the diameter up,letting the gases pass between the bullet and bore.Result:lots of fun at home if scrubbing a bore is your definition of having a good time;not my cup of tea!
