Each bullet potentially "represents a dead American," wrote retired Maj. Gen. Jerry Curry, an Army vet.

Evidently the good Maj. Gen. did not require his personnel to practice on the range.... And yes, you need more than six rounds to practice and yes, you need the same exact rounds in practice as you use in the field.
From Snopes:
"Origins: An August 2012 Infowars.com post pointed to a Request for Quote (RFQ) issued by the Social Security Administration (SSA) for the purchase of 174,000 rounds of ".357 Sig 125 grain bonded jacketed hollow point pistol ammunition." The article opined that as the ammunition was to be sent to a number of major cities around the U.S., it was "not outlandish to suggest that the Social Security Administration is purchasing the bullets as part of preparations for civil unrest."
In fact, the spreadsheet showing the destination locations of the ammunition to be purchased by the SSA indicated that it was for "duty carry" purposes and was being procured for Field Division locations of the Office of Investigations (OI), part of the SSA's Office of the Inspector General (OIG). The OI "conducts and coordinates investigative activity related to fraud, waste, abuse, and mismanagement in Social Security Administration programs and operations" and "conducts joint investigations with other Federal, State and local law enforcement agencies."
The OIG's Office of External Relations posted a notice explaining that the reason behind the ammunition procurement was to supply the nearly 300 special agents who work for the OIG and are armed while on duty:
Our office has criminal investigators, or special agents, who are responsible for investigating violations of the laws that govern SSA's programs. Currently, about 295 special agents and supervisory special agents work in 66 offices across the United States. These investigators have full law enforcement authority, including executing search warrants and making arrests.
Our investigators are similar to your State or local police officers. They use traditional investigative techniques, and they are armed when on official duty.
Media reports expressed concerns over the type of ammunition ordered. In fact, this type of ammunition is standard issue for many law enforcement agencies.
OIG's special agents use this ammunition during their mandatory quarterly firearms qualifications and other training sessions, to ensure agent and public safety. Additionally, the ammunition our agents use is the same type used at the Federal Law Enforcement Training Center.Our special agents need to be armed and trained appropriately. They not only investigate allegations of Social Security fraud, but they also are called to respond to threats against Social Security offices, employees, and customers.
A similar invitation for bids to supply 46,000 rounds of hollow point bullets along with 500 paper targets was issued by the National Oceanic and Atmospheric Administration (NOAA). That ammunition is destined for the NOAA's National Marine Fisheries Service (NMFS), which is tasked with protecting fish stocks from depletion, marine mammals from extinction, the livelihoods of commercial fishers, the hobbies of recreational fishers, and the health of seafood consumers." NOAA spokesman Scott Smullen stated that the ammunition is
"standard issue for many law enforcement agencies, and it will be used by 63 NOAA enforcement agents in their twice annual target qualifications and training."Last updated: 16 August 2012 "
