Precision Barrel Blanks - An EABCO barrel blank is precision gun drilled from the best Chromoly and Stainless steel alloys. Bore dimensions are reamed consistent to airgauge within .0002" (2/10,000ths) of proper bore dimension. These are then Two-Pass button rifled in the various twist rates we offer to suit particular accuracy requirements. One at Time Barrel Making - True, center-to-center barrel turning at a rate that minimizes stress while keeping the bore in the middle. True, center-to-center chamber reaming insures centering and linear alignment of the chamber with the bore. Each chamber's headspace is checked and confirmed with gauges. True, center-to-center 11° target crown, applied after finishing, insures that bullets exit the barrel with perfectly even gas pressure. (You can tell an EABCO Accuracy Barrel by the bright metal crown). Encore Accuracy Barrels are available in several popular chamberings, off-the-shelf or made-to-order.
