Do neck bushings and mandrels actually make a measurable difference in rifle accuracy? In this test we neck-turn and size brass with and without bushings/mandrels, record concentricity and neck wall uniformity, and then run a live accuracy validation to see if the math translates to tighter groups. Tools used: mandrel mandrel sizing, neck bushings, concentricity gauge, calipers, and live chronograph.
What you’ll learn: when bushings help, when they don’t, and how to prioritize your time at the bench. No fluff — just repeatable numbers.
