Muzzle velocity of ar 1510/6/2023 In this post, I’m posting a few quality examples of what I’m talking about. The physics of ballistics don’t change just because you went from an AR-15 to a bolt action.Įverything I’ve written here comes from years of reading, competing, training, practicing, and writing articles for this blog and elsewhere. While I’m focusing on the AR-15 platform in particular, the principles apply to any firearms barrel. This article summarizes just about everything I’ve learned about AR-15 barrels. Companies throw a lot of marketing dollars around to convince you that you need the latest and greatest or you’re going to lose the match, be uncool, or even wind up dead in the street! "In general, I would expect the prognosis for someone who's been shot with a military-grade weapon to be much worse, the likelihood of getting them out of the trauma bay to the operating room to survive the hospital stay, I would be much less optimistic," Griggs said.Selecting the “right” AR-15 barrel is probably the most difficult choice to make, especially for beginners. Multiple wounds often mean identifying which injuries are the most severe and need to be treated first, but unfortunately not all patients can be saved. "We'll see people who come in not with one hole or two holes but with six, eight, 10 holes and trying to sort of piece that out to figure out what organ systems might be injured based on the trajectory, just trying to determine what that trajectory is can be significantly more complicated." "So, it can be a little bit more confounding to understand the connection of all of the different holes." "We've learned that, while shooters often don't shoot well, the semi-automatic weapons increase the likelihood that someone will be shot multiple times," Shapiro said. However, those injured by high velocity weapons, such as AR-15-style rifles, are more likely to have serious injuries. The initial triage process of treating victims of handgun wounds and semi-automatic rifle wounds is the same, including making sure breathing, blood pressure and circulation are stable and assessing if there are spinal injuries or other internal injuries. There's nothing that trauma surgery team could do and that is very classic of what we have come to see as the norm." Treating a wound from a semi-automatic rifle "And devastatingly, the children who were shot in Nashville were dead on arrival to the hospital. "When we see a child who has been shot with an AR-15-style rifle, there is often very little hope - depending on where the bullet has hit them in their body - that we can save their life even if they make it to the hospital," she said. including Sandy Hook Elementary School in Newtown, Connecticut, in 2012 and Robb Elementary School in Uvalde, Texas, last year. Griggs said this has been seen in the multiple mass shootings that have occurred in schools across the U.S. Not just going to completely shatter their liver, but also their spleen, causing catastrophic fatal bleeding." "And so, you can imagine that a bullet that is causing a blast effect inside their body, inside their abdomen or their torso or their chest, it's not just going to explode, or tear apart, their lung, but also their heart. "Children, their organs are a lot more compact, and they have a lot less fat surrounding their vital organs," Griggs said.
