The Ammo Equation: How Much Ammo Do You Really Need?

Those of us who have lived through ammo shortages in the past are not surprised that ammunition is getting harder to find and more expensive under these pandemic conditions.  You need an ammo stockpile.  Here is one opinion about how much you need for a basic stash. 

In my opinion, ammo is only going to get more expensive and harder to acquire in the future.  I prefer to work towards the goal of having a lifetime of practice ammunition in storage.

When a Gun Is Not a Gun


Fascinating information about the science behind mistaken identity shootings.  From the article:

In a dangerous, high-pressure situation such as a possible crime scene, it’s conceivable that some police shooters actually see a weapon when none is present. Other research from our lab (done by Professor Wormwood in collaboration with the psychologist David DeSteno) supports this possibility. In a set of five studies published in 2010 in the Journal of Personality and Social Psychology, we asked test subjects to identify whether individuals were holding guns or harmless objects like wallets and cellphones. Our subjects reported more weapons when they were feeling angry, regardless of what the individuals were actually holding.

Let us reiterate: We are not claiming that affective realism is the preferred explanation for police shootings that involve the misidentification of weapons. Nor are we claiming that racial bias has had nothing to do with such shootings. Indeed, affective realism may be one pernicious way in which racial bias expresses itself.

What we do know is that the brain is wired for prediction, and you predict most of the sights, sounds and other sensations in your life. You are, in large measure, the architect of your own experience.”

Keyword Anti-Targeting: What to Know, What to Avoid, and Why You Shouldn’t Worry

Why I think using paid subscription services (like Patreon and similar companies) is the way forward with niche bloggers in one of the “bad” industries. Check out this article and think about my site.

How many of those words are used in every single article on my site? Advertisers shun websites that regularly use the “forbidden words.” I use 16/20 of the worst words on a weekly basis in my articles.

You wonder why you don’t see articles containing deeper thinking on the topic of criminal violence and terrorism? Wonder why you see so many banal gun and gear reviews? This is the reason. There’s no ad revenue coming in for articles that describe criminal violence.



The Importance of Situational Awareness

“It is critically important that, once a potential threat is spotted, we keep it under constant observation. This is not the time to watch a while and then go back to shopping, reading your book or that friendly conversation. We keep the potential threat in view until the threat leaves, we leave or the matter is otherwise resolved. Let me repeat—don’t take your eyes off of a potential threat.

In the meantime, you should be formulating a plan. Where is the nearest exit? Where is the nearest cover? If you are carrying things, it’s time to put them down and free your hands. It is also time to open whatever covering garments you might have on for freer access to your defensive firearm.”
