    Sectioning ammunition is tricky, especially of the ammunition has tracer compound or other especially flammable substance integral to the bullet. Great care must be taken to to avoid the ignition of the primer, propellant, or other components. Wolfgang has great skill in doing this, and it shows in the products of his labor!
