[QUOTE="barnesuser28, post: 778678, member: 43468"] The reason they might need a break-in is the throat has tooling marks going across the bullet travel from your gunsmiths reamer or neck throater. And that roughness shears bullet jacket off and the copper becomes a plasma because of the extremely hot temps and pressures from the expanding gasses of the gun powder and as it cools on its way down the barrel it gets deposited into the barrel.
