The Bureau of Land Management is planning a truly boneheaded move, angering some conservationists over the affects to herd populations and migration routes. From Field & Stream.
The Bureau of Land Management (BLM) recently released a draft plan outlining potential solar energy development in the West. The proposal is an update of the BLM’s 2012 Western Solar Plan. It adds five new states—Idaho, Montana, Oregon, Washington, and Wyoming—to a list of 11 western states already earmarked…… [read more]
I hate the NRA, but this type of information and certifying firearms courses and instructors really is what they should focus on, leaving rights advocacy to the adults.
We hear this term bantered about a lot when it comes to ammunition. But what exactly does it mean, and how does it affect your success in the field or for self-defense?
Terminal performance is how a bullet or other projectile reacts, and the ability of it to stop a human threat or take down an animal. In other words, hunters rate a bullet’s terminal performance in how quickly a projectile kills game animals. Soldiers, law enforcement officers and responsible citizens in self-defense situations rate terminal performance on how quickly a projectile neutralizes a threat. It all relates to how deeply a bullet penetrates to reach the vital organs and cause tissue damage.
Terminal performance is often referred to as “knock-down” or “stopping” power. It is not whether the bullet kills, but how quickly and consistently. Terminal performance has a lot to do with bullet design and the ballistics of the cartridge.
Target shooters are not as concerned with terminal performance as they are in punching holes in paper. They are looking for consistent bullet placement in a tight grouping where they are aiming. Those who use a gun for hunting, and those who carry a gun to defend freedom—like our soldiers, men and women in blue, or citizens who carry for personal protection—are concerned with the terminal performance of a bullet. Remember, if you use a firearm, you have the potential to use deadly force. Using a firearm should be your last resort if you have no other option and it is either you or the assailant. Stopping a threat, whether human or animal, is done in two ways: by causing severe damage to the vascular system and interrupting or stopping the flow of oxygenated blood to the brain; or causing severe damage to the central nervous system in the brain or cerebellum.
There are three things that a bullet needs for terminal performance: bullet expansion, bullet penetration and bullet velocity. All three are related to bullet design and all must work in concert to get the required performance.
