2 Questions for swagers[ I looked it up and I've been spelling it wrong--I apologize ,but now you guys who mispell VARMINT have to change too! }---- Could an off the shelf 20 ga. slug be extruded to a .505" dia,then trimmed to a length/weight that would work in a 28 Ga.? What diameter is the BODY of the 20 ga. slug and the height of the fins ? The "knob" of the 28 ga.cushion/seal could be gripped by the flowing ,extruded lead and provide retention of the seal. KL
