The Wilson Decapping Base, .380 (L.E. Wilson part no. PBB-380), is a case-hardened base sold on its own that pairs with a compatible punch to de-cap primers from the case while providing a stable base to work against. Many precision shooters prefer to punch primers out as a separate operation before sizing, which works especially well for military-crimped primers. To determine the correct size, measure your case head diameter; for example, a 223 Remington head measures .375 inch, so it takes a .380 base like this one. It is manufactured in the U.S.A. and available for most calibers.
