PMC ammunition is loaded in new brass cases with boxer primers. This ammunition is non-corrosive and is loaded to SAAMI specifications. Each of these rounds complies with MIL SPEC. All PMC ammunition is reloadable. Rifle ammunition may have crimped military primers. In reloading, the crimped first needs to be removed before a new primer can be inserted. Most major reloading companies can provide a tool to accomplish this operation.
