Description

Hornady OAL Modified Case 300 AAC #5A300A

The cases are modified to work with the precision Lock-N-Load gages. To attach them to the jars, they remain perfectly placed for accurate alignment in your firearms chamber, a special fine thread is used. Second, a standard diameter bullet falls into a case without effort but concentratedly, allowing the case to achieve the most exact results. The neck of the case is made perfectly round and slightly opened.
