The RCBS AR Series Small Base Die Set, 6.5 Creedmoor (RCBS part no. 32907) is built for progressive reloaders running 6.5 Creedmoor through a semi-automatic, AR-platform rifle, where a standard sizing die can leave just enough case taper to cause a chambering issue. The Small Base Sizer Die resizes the case body down further than a standard die, guaranteeing the finished round re-chambers reliably in an AR-platform gun.
