I-US Marine Corps ishintsha izibhamu zayo ezikhona kakade ifake imodeli entsha edubula inhlamvu enzima, yebanga elide. Isibhamu esisha se-Mark 13 Mod 7 sniper, intandokazi yama-Navy SEALs sithatha isikhundla sochungechunge oludala lwezibhamu ze-M40. Umphumela uba isibhamu esinembe kakhudlwana esinamandla okushaya okuqondiwe cishe izingxenye ezintathu kwezine zemayela.

Uchungechunge lwezibhamu ze-M40 lusebenze i-Marine Corps iminyaka engaphezu kwengu-50. Eyethulwe ekuqaleni ngesikhathi seMpi YaseVietnam, i-Marine Corps yathenga izibhamu ze-Remington Model 40X ze-bolt-action varmint ezinemiphongolo esindayo, zashaywa ku-Redfield 3-9x wamandla aguquguqukayo, futhi yazinikeza igama elithi M40.

Naphezu kokuthuthukiswa, uchungechunge lwe-M40 lukhawulelwe ama-ballistics omjikelezo we-.308 Winchester. Nakuba ukuzingela okuphumelelayo nomjikelezo wezempi, umjikelezo ongu-a.308 ulahlekelwa amandla ngokushesha ngemva kwamayadi angu-700. Kumayadi angu-600, i-sniper ehlome nge-M40 ingalindela ukuthi inhlamvu yehle ngamaintshi angu-105 eduze kwalapho kuhlosiwe, okudinga isinxephezelo esingaphezulu esingamayintshi angu-105 ukuze sihlale kuthagethi. Kumayadi angu-800 amabhaluni ehlayo ukuya kuma-intshi angu-228, futhi kumayadi angu-1,000 ukwehla kungu-421 amayintshi. Lokhu kulahlekelwa kwamandla kuphinde kuthinte ukukhukhuleka komoya, okuthi .308 kudinga amayintshi angu-53 okulungiswa komoya emoyeni wamamayela amahlanu ngehora ukuze ufinyelele ithagethi kumayadi angu-1,000. Ibanga eliphezulu elisebenzayo lochungechunge lwe-M40 licishe libe ngamayadi angu-1,000.

Izilungiso ezimbalwa i-sniper okumelwe izenze ukuze ishaye kangcono ibanga elide, futhi abadubuli ababukhali bafeza lokhu ngokusebenzisa umzuliswano osindayo, onamandla aphezulu. Ngokungafani nomjikelezo omdala ongu-.308, i-.300 Winchester Magnum enkulu isebenza kahle ngamayadi angu-1,300. Idinga kuphela amayintshi angu-246 okulungiswa okuqondile kumayadi angu-1,000, kanye namayintshi angu-40 okulungiswa okuvundlile kumayadi angu-1,000 emoyeni wamamayela amahlanu ngehora. Umzuliswano osindayo futhi ushaya ngamandla engeziwe kumabanga amade, okwenza kube maningi amathuba okuthi kukhubaze okuqondiwe. Ububanzi obuyindilinga obungu-.300 bungamayadi angu-1,300.
