What happens, though, when that kind of performance is scaled up to .30 cal size and fired from a .308 Winchester? William has us covered there, too.<\/p>\n<p>In the video, you can see the excellent design of the EPR-type projectile at work: Immediate and reliable disruption coupled with large fragments that give good penetration together create as ideal a wound channel for general purpose military use as is possible with current technology. A great deal of work went into creating the best possible projectile design; you can read more about the history of that effort\u00a0<a href=\"http:\/\/www.thefirearmblog.com\/blog\/2014\/08\/21\/weekly-dtic-m855a1-story\/\">at these<\/a> <a href=\"http:\/\/www.thefirearmblog.com\/blog\/2014\/07\/28\/weekly-dtic-fleet-yaw-problem-improving-rifle-effectiveness\/\">two links<\/a>.<\/p>\n<p>M80A1 uses a lighter 130gr projectile than its nought mark 147gr predecessor, M80. The construction of the new projectile is the same as the 5.56mm M855A1, with a copper \u201cslug\u201d, hardened steel penetrator, and both wrapped in a gilding metal jacket.<\/p>\n<p>During filming of this video, William was just working up loads to figure out which would best replicate the Army\u2019s M80A1, which he believed to produce 2,950 ft\/s muzzle velocity. In fact, according to <a href=\"http:\/\/www.dtic.mil\/dtic\/tr\/fulltext\/u2\/a567897.pdf\">PEO Soldier\u2019s 2013 Ammunition Portfolio<\/a>, M80A1 produces 3,050 ft\/s <strong>at 78 ft<\/strong> from a 24.8\u2033 M240 barrel, which would mean roughly 3,050-3,060 ft\/s <strong>at the muzzle<\/strong> from a 22\u2033 barreled weapon, such as an M14. William told TFB that high speed footage of M80A1 in partnership with Aimed Research is in the works, so stay tuned!<\/p>\n<p>Read the Original Article at<strong><a href=\"http:\/\/www.thefirearmblog.com\/blog\/2016\/06\/16\/wound-channel-tests-7-62-308-m80a1-epr-glorious\/\"> The Firearms Blog<\/a><\/strong><\/p>\n<p>You Can Read A More In-Depth Analysis of this Round at <strong><a href=\"http:\/\/www.thefirearmblog.com\/blog\/2016\/07\/23\/taking-a-look-inside-the-armys-devastating-new-m80a1-7-62mm-round\/\">TFB<\/a><\/strong><\/p>\n<p>Please Subscribe to <strong><a href=\"https:\/\/www.youtube.com\/channel\/UCwsEFHahtESl91JuTlhUJEg\">The Wound Channel<\/a><\/strong> on YouTube if you like Ammo Testing<\/p>\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Previously, we looked at the incredible damage and penetration caused by the US Army\u2019s new M855A1 Enhanced Performance Round (EPR), thanks to a video published by William of the Wound Channel.
