Weekend Knowledge Dump- February 28, 2014

Here are a few links to articles and videos I found interesting this week. Some are intellectual. Some are informative. Some are just fun. If you have some free time, check them out this weekend.

 

 

How to Prepare for a Big Moment

The best mental preparation involves a balance of planning responses to failure and visualizing success.

20 Gauge Segmenting Slug

s12pdx1s_slug_segmentedWinchester has released its innovative segmenting slug in a 20 gauge loading.  I really like this slug’s performance and will be picking some of these up for my 20 gauge defensive shotguns.  For some test results of this load in 12 gauge, see my test results HERE.

 

 

15 Reasons to Sprint More This Year

I’m a big fan of sprinting, both for exercise and for survival training.  When is the last time you ran an all-out sprint?

 

 

Debunking the Myth of the 10,000-Hours Rule: What It Actually Takes to Reach Genius-Level Excellence

goreytreehorn4

The article doesn’t really debunk the idea, it clarifies some of the issues.  Practice time isn’t the largest factor in acquiring competency, it is focused and concentrated practice with a goal of improvement.  Coaches and feedback can speed the process along.

 

 

Sinister Studies: Serious Scrutiny into Southpaw Shooting (Part 1)

lefty3-300x300

An excellent resource for you left handed shooters.  Even if you aren’t a lefty, you should learn how to run a gun left handed in case and injury takes your right hand out of the fight.  Part Two covers left hand only reloads and malfunction drills.  Part Three covers left handed revolver manipulation.

 

 

The Medieval—and Highly Effective—Tactics of the Ukrainian Protests

Amazing videos and analysis of the Medieval tactics used by the Ukrainians to defend themselves against attacks by pro-government forces.  Learning these kind of tactics may be useful in the future.

 

 

John Boyd’s Roll Call: Do You Want to Be Someone or Do Something?

boydpic

It’s unusual to find an article about John Boyd, so I’m happy to see this one.  Boyd was a true tactical genius who developed the OODA loop.  All students of the combative arts should be thoroughly grounded in his theories of maneuver warfare.  A good place to start is Robert Coram’s book.

 

 

Head shots and ricochets.

Grant Cunningham adds some good information about why head shots may ricochet off a criminal’s skull.

 

 

Underwood Ammo 380 +P 80 Grain TAC-XP Denim and Clear Gel Test – See more at: http://mousegunaddict.blogspot.com/2014/01/underwood-ammo-380-p-80-grain-tac-xp.html?utm_source=feedburner&utm_medium=feed&utm_campaign=Feed%3A+PocketGunsAndGear+%28Pocket+Guns+and+Gear%29#sthash.wGjaJRRz.dpuf

Underwood Ammo .380 Gelatin Tests

IMG_4880_zps9f29fd65

The .380 is a tough gun to feed.  Bullets moving fast enough to expand well rarely penetrate enough.  The slower moving bullets don’t expand.  With the gaining popularity of the caliber, ALL self defense ammo is hard to come by.  This load shows promise.  I’d like to see a little more penetration, but I wouldn’t be uncomfortable relying on this one for self defense purposes.  With the high velocity, it’s probably quite unpleasant in a polymer gun like the LCP or KelTec.  I’d save this one for the Kahr, Beretta, or the new Glock 42.

The modern phenomenon of nonsense jobs

psi-graeber-wide-20130902110935876195-620x349

“If someone had designed a work regime perfectly suited to maintaining the power of finance capital, it’s hard to see how they could have done a better job. Real, productive workers are relentlessly squeezed and exploited. The remainder are divided between a terrorised stratum of the, universally reviled, unemployed and a larger stratum who are basically paid to do nothing, in positions designed to make them identify with the perspectives and sensibilities of the ruling class (managers, administrators, etc) – and particularly its financial avatars – but, at the same time, foster a simmering resentment against anyone whose work has clear and undeniable social value.”

 

 

Modifying A TDI Knife with Tek Lok

images-300x136

The Ka-Bar TDI knife is a very affordable option for a small centerline-carried fixed blade.  It’s the fixed blade knife that I use in all my classes and carry myself.  Occasionally, I see complaints about the sheath’s belt clip.  Here’s how to retrofit a Tek-Lok onto the sheath to make it more secure.  You can also use this method if you would prefer to carry the knife horizontally instead of vertically.

The knife is unbeatable for less than $40 on Amazon.

 

The Tactical Placekicker

Lots of pictures of some very unique homemade machine guns seized by police in Brazil.  It’s amazing seeing the ingenuity spawned by restrictive gun control laws…and another reason why such laws will never work.  If you have access to a third world machine shop, you can make your own guns!

 

Lessons From the Real World – Chicago Gas Station Shooting

Lessons From the Real World – Chicago Gas Station Shooting - Gun Nuts Media 2014-02-24 20-39-05

A lot of people have written to ask for my analysis of the Chicago gas station shooting. The off duty cop performed well, but the incident wasn’t so unusual that I felt the need to analyze it. Tim’s review is a great one if you are still looking for more info.
