.17 HMR
.17 Hornady Magnum Rimfire (4.5×27mmR), commonly known as the .17 HMR, is a rimfire rifle cartridge developed by the ammunition company Hornady in 2002. It descended from the .22 Magnum by necking down the .22 Magnum case to take a .17 caliber (4.5 mm) bullet. Commonly loaded with a 17 grain (1.1 g) bullet, it can deliver muzzle velocities in excess of 775 m/s (2550 ft/s).
Development
The .17 HMR round is similar to rounds developed by dedicated rimfire wildcatters who worked to create a rimfire cartridge with an exceptionally flat trajectory. These wildcatters were seeking to match the ballistics of the obsolete 5mm Remington Magnum Rimfire, which was made from 1970 to 1974, and was to that point the fastest rimfire cartridge ever produced. With 5mm (.20 caliber) diameter barrels and bullets being virtually unavailable at the time (the 5mm RMR was the last commercial 5mm round until the 2004 release of the centerfire .204 Ruger), the commercially available .17 caliber became their bullet of choice. The .22 Winchester Magnum Rimfire was the logical parent case, rather than 5mm RMR (with its unique case head size, which requires a significantly different bolt and magazine), because it was commonly available, and it is a far larger and stronger case than the next largest .22 Long Rifle. The .17 caliber wildcats not only met, but far exceeded the 5 mm RMR's velocities and flat trajectory. The accuracy of these cartridges was also quite good. However, the downrange energy of the 5mm RMR is superior to both .22 WMR and .17 HMR, so there is still potential in the 5mm rimfire for wildcatters.
VMM-774
Marine Medium Tiltrotor Squadron 774 (VMM-774) is a United States Marine Corps medium helicopter squadron consisting of V-22 Osprey transport helicopters. The squadron, known as the "Wild Goose", is a United States Marine Corps Reserve unit based at Naval Station Norfolk (Chambers Field), Virginia and falls under the command of Marine Aircraft Group 49 (MAG-49) and the 4th Marine Aircraft Wing (4th MAW).
With the deactivation of training squadron HMMT-164 and re-designation as VMM-164 on April 9, 2015, HMM-774 was the last dedicated CH-46E squadron in the Marine Corps.
Mission
Support the MAGTF Commander by providing assault support transport of combat troops, supplies, and equipment, day or night, under all weather conditions during expeditionary, joint or combined operations
Maintain combat readiness and provide support to the 4th Marine Aircraft Wing. Missions include assault support, CASEVAC, helicopter support team training and SEAL team support.
History
Marine Medium Helicopter 774 was activated September 5, 1958, at Naval Air Station New York as Marine Transport Helicopter Squadron 774 (HMR-774). The squadron operated the SH-34G/J Sea Bat helicopter. In April 1962 the squadron was redesignated Marine Medium Helicopter Squadron 774, but was deactivated on 30 September 1962.
VMM-163
Marine Medium Tiltrotor Squadron 163 (VMM-163) is a United States Marine Corps helicopter squadron consisting of MV-22 Osprey transport tiltrotors. The squadron, known as the "Ridge Runners", is based at Marine Corps Air Station Miramar, California and falls under the command of Marine Aircraft Group 16 (MAG-16) and the 3rd Marine Aircraft Wing (3rd MAW).
The Squadron's nickname, "Ridge Runners", was bestowed as a result of typhoon rescue and relief operations in the mountainous terrain surrounding Hagman, Japan.
Mission
Provide assault support transport of combat troops, supplies and equipment during expeditionary, joint or combined operations. Be prepared for short-notice, worldwide deployment in support of Marine Air-Ground Task Force operations.
History
Vietnam War
HMR(L)-163, the predecessor of HMM-163, was formed in December 1951. From February to October 1965, the HMM-163 "Ridge Runners" helicopter squadron became famous for its operations in Viet Nam. This was primarily due to a LIFE magazine story that documented the combat death of Marine H-34 pilot 1st Lt James E. Magel and the rescue of wounded and paralyzed 1st Lt Dale Eddy during a strike mission transporting South Vietnamese troops. For most U.S. citizens, this was the first time they were made aware of the extent of America's involvement in Viet Nam.
