April 22, 2018 -- A Quick Run Around the Web

The producer of this video tests the new Glock Marksman barrel versus the Polygonal barrel. Using 147 grain and 115 grain ammunition, he found a noticeably higher velocity for the 147 grain in the polygonal barrel versus the Marksman barrel; but only a negligible difference when comparing the 115 grain. Accuracy was noticeably better, however, using the Marksman barrel over the polygonal. 

  • Be careful what you wish for: "CDC, in Surveys It Never Bothered Making Public, Provides More Evidence that Plenty of Americans Innocently Defend Themselves with Guns"--Reason. Gary Kleck and Marc Gertz published a study in 1995 reporting that there were between 2.1 million and 2.5 million defensive gun uses (DGUs) per year by Americans. These findings have been severely criticized by the left, and various anti-gun researchers have concluded that the number of DGUs per year is in the tens of thousands to hundreds of thousands, but certainly much less than Kleck and Gertz's findings. For instance. a 2013 study by the Violence Policy Center concluded that there were only 67,740 DGUs per year. Because of the large discrepancies, the left has wanted the Centers for Disease Control to research the issue and give its imprimatur on the conclusions that firearms aren't widely used for self-defense. It appears, however, that the reason the CDC didn't want to conduct the research was because it already had ... and its conclusions matched those of Kleck and Gertz. That is, that firearms were used nearly 2.5 million times a year for self-defense.
  • "Legally Armed People Have a Murder rate similar to Japan"--Ammo Land. "Within the United States, there is a law abiding culture that has a murder rate as low as Japan's. That culture consists of gun owners who carry guns legally." The author bases this on 14 years of Michigan records that showed 17 criminal convictions of CCL holders for murder during that period, working out to a murder rate of 0.43 murders per 100,000 CCL holders. 
  • Five more reasons for a 30-round magazine: "Home Invasion Victims Use AR–15 To Defend Themselves Against Five Armed Intruders"--The Daily Caller. The article reports that "[t]he armed victims shot about 30 rounds, killing the gunman who wore a mask — Corey Lauramore — and wounding two others — William Lauramore and an unidentified 16-year-old." But here is the scary part: the intruders attempted to pass themselves off as a law enforcement raid: 
       Three men were asleep inside their Glen St. Mary, Fla., mobile home when five young intruders claiming to be police broke down the front door at 4:00 a.m. on Tuesday, News 4 Jax reports.
            The first intruder wore a mask and shouted, “Sheriff’s office!” from outside the trailer before breaking the front door down and shooting a single round.
    This is not that uncommon. And the problem for the homeowner is determining whether it is a criminal home invasion or police action. 
    • "How Many Gallons of Propane in a 20 lb Tank"--Modern Survival Blog. According to the author, a standard 20-lbs tank can hold 5 gallons of propane, but for safety reasons, should only be filled 80% full, or about 4 gallons (or 17 lbs). He also notes how the exchange dealers rip you off: "Apparently today’s ‘exchange’ propane tanks are only filled with 15 pounds, or about 3.5 gallons."
    • "Looking For a Long-Gun Light? Crimson Trace Has 4 New Options"--Range 365. The 4 options are offered in 500 or 900 lumen, and mountable to a Picatinny rail or M-Lok/K-Mod, starting at an MSRP of $60 to $80, depending on the particular model, which includes a touch pad to activate the light.
    • "THE MYTHS OF THE AFTERMATH"--Suarez International. Gabe Suarez attempts to dispel myths on surviving the aftermath of a defensive gun use. He notes that the police will see you in one of two lights--as the victim or the perpetrator--and your job in the aftermath is to make sure that the police know that you are the victim. Thus, he notes that you will need to call the police to report the incident--if you don't, the police will assume that you are the perpetrator. (See Part 2, here).
    • "Preparing an Urban Emergency Kit"--American Rifleman. The author discusses several options and recommendations, and explains his choices. He recommends a single strap bag instead of a backpack; two or three sources of illumination (and a portable charger for your cell phone); work gloves, dust mask, foam earplugs, and safety glasses; a light jacket; a bandanna; "sensible shoes" (i.e., something you can actually use to walk long distances or run); a knife and/or multi-tool; some first aid supplies (the photograph he uses includes a tourniquet); and some high energy foods and bottles of water. He also discusses whether to include a firearm. Anyway, great article and worth the read.
    • "Terminal ballistics: The wound cavity"--Sporting Rifle Magazine. An excerpt:
              ... Apart from the small amount of heat generated as the bullet passes through tissue, most of the energy is converted to elastic energy.
                Tissue within the body of your quarry has a certain amount of elasticity. Pinching your own skin is a demonstration of this. In the same way that the ballistic gel expands and stretches as the bullet passes through it, so too will flesh (we will tackle the effects on organs later). The extent to which a medium will stretch is defined as its elasticity, which – for those engineers among us – is determined by Young’s modulus, which is a ratio of stress over strain. Intuitively, it is easy to see that the more elastic a medium is, the larger the temporary cavity will be, as a given amount of energy transferred from the bullet will push the medium more easily away.
                  What’s interesting is that after the temporary cavity expands and collapses, residual energy remains. This creates a secondary temporary cavity, expanding once again before collapsing. This continues in a pulsing motion until no elastic energy is left. Just like the declining height with which a ball bounces, each created cavity will be smaller than the last. During this time, debris can be pulled into both the entry and exit wound.
                    With the tissue relaxed back to its stable state, we are left with a permanent wound channel of destroyed tissue, and an area around this known as the extravasation zone. Unlike the permanent wound channel, which can be defined visually from the by the residual signature left behind in the ballistic gel, the extravasation zone shows no visual destruction. Here, the stretching imposed by the temporary cavity isn’t sufficient to tear tissue, but is enough to rupture sensitive parts of the body such as capillaries. ...
            On Friday evening, President Donald J. Trump inadvertently referred to the disgraced Congresswoman Debbie Wasserman Schultz as "Wendy." In hysteria, the media and blue-check marked liberals on Twitter erupted with laughter as the tweet sat there for twenty minutes. President Trump finally deleted that mistake and replaced it with a tweet featuring her proper name. 
            It wasn't a mistake. Q recently posted about "Wendy." Now we know who was "Wendy."
            A large number of seasonless Americans fall into this category, including Paul Ryan, white women who work at nonprofits and anyone who believes in reverse racism. Businesses include Cracker Barrel and your church. Yes, yours.
                     Gang-related gun murders, now mainly a phenomenon among men with immigrant backgrounds in the country’s parallel societies, increased from 4 per year in the early 1990s to around 40 last year. Because of this, Sweden has gone from being a low-crime country to having homicide rates significantly above the Western European average. Social unrest, with car torchings, attacks on first responders and even riots, is a recurring phenomenon.

                        Shootings in the country have become so common that they don’t make top headlines anymore, unless they are spectacular or lead to fatalities. News of attacks are quickly replaced with headlines about sports events and celebrities, as readers have become desensitized to the violence. A generation ago, bombings against the police and riots were extremely rare events. Today, reading about such incidents is considered part of daily life.
