One of the great things about 300 Blackout is that it is available as both a supersonic round and a subsonic round. Supersonic 300 Blackout has bullet weights and velocities that are similar to 7.62x39mm ammunition. Subsonic 300 Blackout, on the other hand, has bullet weights around 200 grains and is quite similar to 45 ACP. Guns and ammo don\u2019t exist in a vacuum, though, so today we\u2019ll be looking at the idea of 300 Blackout for home defense.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">There are a lot of advantages at first glance for using 300 Blackout for home defense. 300 Blackout was designed from the ground up to use a suppressor and <\/span><a href=\"https:\/\/www.ammoman.com\/blog\/subsonic-ammo-bang-without-the-sonic-boom\/\"><span style=\"font-weight: 400;\">subsonic ammunition<\/span><\/a><span style=\"font-weight: 400;\">. Guns are loud (really loud) and using a firearm without a suppressor indoors can cause permanent hearing damage to yourself and your loved ones.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Another advantage to using 300 Blackout for home defense is how it works with AR pattern guns. The <\/span><a href=\"https:\/\/www.cnn.com\/2017\/12\/14\/health\/ar15-rifle-history-trnd\/index.html\"><span style=\"font-weight: 400;\">AR-15 is one of the most-common rifles<\/span><\/a><span style=\"font-weight: 400;\"> in America and is an excellent self-defense firearm. 300 Blackout uses the standard AR-15 magazine, as well as many receiver parts. This means that if you can just as easily shoot an AR-15 chambered in 300 Blackout as you can an AR-15 chambered in 5.56mm or .223 well.\u00a0<\/span><\/p>\n<h3><span style=\"font-weight: 400;\">Optimizing 300 Blackout for Home Defense<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">We know from previous testing that subsonic 300 Blackout ammunition is more than up to the task of stopping a threat to our lives. The question we\u2019ll be answering today is, how effective is 300 Blackout for home defense? What happens if you miss the target, and your round goes sailing off through an interior wall? What effect might that have on an innocent person behind that wall? Preventing innocent people from being injured by guns is the reason why we have the four rules of gun safety. Our accuracy can degrade in a stressful situation when lives are on the line, and we can miss the target and hit something else. Therefore, a good home defense ammo should have enough power to stop the threat, but minimize the damage it might cause if we miss.\u00a0<\/span><\/p>\n<div id=\"attachment_3710\" style=\"width: 310px\" class=\"wp-caption alignright\"><a href=\"https:\/\/www.ammoman.com\/blog\/media\/amax_testing.jpg\" data-rel=\"lightbox-image-0\" data-magnific_type=\"image\" data-rl_title=\"\" data-rl_caption=\"\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-3710\" class=\"wp-image-3710 size-medium\" title=\"\" src=\"https:\/\/www.ammoman.com\/blog\/media\/amax_testing-300x130.jpg\" alt=\"300 Blackout hitting wall\" width=\"300\" height=\"130\" srcset=\"https:\/\/www.ammoman.com\/blog\/media\/amax_testing-300x130.jpg 300w, https:\/\/www.ammoman.com\/blog\/media\/amax_testing-1024x443.jpg 1024w, https:\/\/www.ammoman.com\/blog\/media\/amax_testing-768x332.jpg 768w, https:\/\/www.ammoman.com\/blog\/media\/amax_testing-1536x664.jpg 1536w, https:\/\/www.ammoman.com\/blog\/media\/amax_testing-2048x886.jpg 2048w, https:\/\/www.ammoman.com\/blog\/media\/amax_testing-610x264.jpg 610w, https:\/\/www.ammoman.com\/blog\/media\/amax_testing-1080x467.jpg 1080w, https:\/\/www.ammoman.com\/blog\/media\/amax_testing-627x271.jpg 627w\" sizes=\"auto, (max-width: 300px) 100vw, 300px\" \/><\/a><p id=\"caption-attachment-3710\" class=\"wp-caption-text\">300 Blackout tends to yaw and tumble when it hits something<\/p><\/div>\n<p><span style=\"font-weight: 400;\">The interior wall of a typical home is made from 2&#215;4 lumber spaced 16 inches apart with one sheet of drywall attached to each side. We\u2019ve built a number of 16 inch square test walls that replicate this type of construction. We\u2019ll be shooting at each of those test walls from a distance of 10 feet. We\u2019ll place a block of clear ballistics gel one foot behind that wall to measure the effects of a missed shot on someone who wasn\u2019t the initial target.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Lastly, we\u2019ll place a 4 foot by four foot wall built the same way as the first wall. That final wall will be at a distance of 12 feet behind that first wall, which is a common distance in between walls in the typical American home.\u00a0<\/span><\/p>\n<h3><span style=\"font-weight: 400;\">Interior Wall Penetration Test<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">We\u2019ll be testing three rounds each of three different kinds of 300 Blackout ammo:<\/span><\/p>\n<p><a href=\"https:\/\/www.ammoman.com\/300-aac-blackout-sellier-bellot-124-grain-fmj-sb300blka-500-rounds\"><span style=\"font-weight: 400;\">Sellier &amp; Bellot 124 grain FMJ Supersonic<\/span><\/a><br \/>\n<a href=\"https:\/\/www.ammoman.com\/300-aac-blackout-hornady-subsonic-190-grain-sub-x-20-rounds\"><span style=\"font-weight: 400;\">Hornady 190 Grain Sub-X Subsonic<\/span><\/a><br \/>\n<a href=\"https:\/\/www.ammoman.com\/300-aac-blackout-hornady-black-208-grain-a-max-80891-200-rounds\"><span style=\"font-weight: 400;\">Hornady 208 Grain Black Subsonic<\/span><\/a><\/p>\n<p><span style=\"font-weight: 400;\">We chose the two Hornady rounds in particular because they delivered radically different results in a recent <\/span><a href=\"https:\/\/www.ammoman.com\/blog\/subsonic-300-blackout-ballistics\/\"><span style=\"font-weight: 400;\">300 Blackout subsonic ballistics<\/span><\/a><span style=\"font-weight: 400;\"> test. The A-Max bullets loaded into the subsonic Black rounds did not destabilize or tumble on impact, but rather yawed and exited the test gel at very different angles from where they entered the gel. The Sub-X round, on the other hand, expanded and slowed down as it hit the testing medium, and all five of our test rounds remained inside the gel.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">We\u2019ll also test the Sellier &amp; Bellot to see what a supersonic 300 Blackout round will do in a home defense situation.

All three of the rounds penetrated at least 16 inches of gel after they passed through the first wall. However, they changed direction so much we could not tell if they had struck the rear wall or not.. All in all, these results were somewhat consistent with our previous test.\u00a0<\/span><\/p>\n<h3><span style=\"font-weight: 400;\">Accuracy Matters Inside Your Home<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">The very low noise associated with a suppressed firearm using subsonic ammunition combined with the wide range of options available for the AR-pattern make using 300 Blackout for home defense a very viable choice. Based on how it performed in our first test along the results from this wall penetration test, I would choose the 190 grain Hornady Sub-X 300 Blackout for home defense, as I feel it offers the best blend of penetration and noise reduction. Stopping the target is the first priority of any defensive round, and Sub-X will do that, while leaving your hearing (and the hearing of your loved ones) intact.\u00a0<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"<p>300 Blackout first appeared on the scene in 2011 as a \u201cdo it all\u201d cartridge for the AR platform.
