Homeland Security shooters are dumping .308 for this long-range round
Not the best article but an interesting development.INDIANAPOLIS ― The Department of Homeland Security plans to get rid of all its 7.62mm NATO, or .308 caliber, long-range rifle ammunition and replace it with an intermediate caliber that Special Operations snipers will field next year — the 6.5mm Creedmoor.
Speaking Monday during a panel at the National Defense Industrial Association Armament Systems Forum here, Devin Patterson, a DHS engineer, told the audience that the switch would give their “tactical observers,” civilian speak for snipers, a more accurate round for their sensitive security missions.
And because the dimensions of the cartridge are not drastically different, the change mostly involves just a barrel change.
“It’s an easy swap,” Patterson said.
