Anything you could want to know about guns or related subjects (It's like Wikipedia for your boomstick) - 5,722 pages as of Tuesday, May 21, 2024.
If it's about guns, gun rights, gun grabbers or any other related subject, sooner or later it's going to be here. Whether it's sniper rifles, shotguns, WWII arms, ammunition or anything else, we're out there scrounging up anything and everything that we can find. Yes, this is something of an ambitious (some would say impossible) project but we're not quitting until we have it all in one place. Have a look around and see some of what our contributors have put together so far.
Some princes, so as to hold securely the state, have disarmed their subjects.... But when you disarm them, you commence to offend them and show that you distrust them either through cowardice or lack of confidence, and both of these opinions generate hatred against you. And because the government cannot remain unarmed, it follows that the government turns to hired police. Therefore a wise prince has always distributed arms to the general population. - Nicolo Machiavelli, The Prince, Chapter 20

Did you know?
The 22-250 is based on the 250-3000 Savage case necked down to .22caliber and is so named because of the caliber (22) and the parent case (250).
Brisance is a measure of the rapidity with which an explosive develops its maximum pressure.
In addition to strength, explosive materials display a second characteristic, which is their shattering effect or brisance (from the French briser, to break), which is distinguished from their total work capacity. This characteristic is of practical importance in determining the effectiveness of an explosion in fragmenting shells, bomb casings, grenades, structures, and the like.
A brisant explosive is one in which the maximum pressure is attained so rapidly that a shock wave is formed, and the net effect is to shatter (by shock resonance) the material surrounding or in contact with the supersonic detonation wave created by this explosive. Thus brisance is a measure of the shattering ability of an explosive.
The sand crush test is commonly employed to determine the relative brisance in comparison to TNT. No single test is capable of directly comparing the explosive properties of two or more compounds; it is important to examine the data from several such tests (sand crush, trauzl, and so forth) in order to gauge relative brisance. True values for comparison will require field experiments.
One of the most brisant of the conventional explosives is cyclotrimethylene trinitramine (also known as RDX).[1]
