The RCBS AR Series Small Base/Taper Crimp Die Set for .22 Nosler (part no. 29707) is built specifically for semi-automatic AR-platform rifles, where a standard sizing die can leave brass slightly too large to reliably rechamber. RCBS pairs a Small Base Sizer Die with a Taper Crimp Seater Die in this two-die set, sizing cases down enough to guarantee they will rechamber in a gas gun and then seating and crimping the bullet in the same setup.
