#.22

.22LR is a popular round for many reasons from its soft report to its minimal recoil – and, of course, it’s just plain fun. It was designed in 1887 by the J. Stevens Arms and Tool Company, and if you really want to trace its roots all the way back they technically began with the Flobert BB cap back in 1845. That said, its parent case is actually the .22 Long, and its bullet comes courtesy of the .22 Extra Long. While many new shooters pick up a .22LR as their first firearm, it’s great for everyone and useful for a variety of things from taking down squirrels and coyotes to plinking away at a row of empty soda cans. Then there’s the fun of seeing just what the .22LR can penetrate, and that’s where YouTuber 22plinkster comes in.

A group called NYC CN C has put together a video on creating a sentry contraption jig that assisted with a computer program, can automatically detect a target, then the shooter uses a string to pull the trigger. They say that everything can be made for $150, and it seems to work pretty well at the 5 meters they are shooting at with a .22 AR15. The actual mechanics of the rotors, and electrics is so far beyond my poor means to comprehend, so maybe some of our more knowledgeable readers can let us in how just how those work.

Anthony Williams, small arms theorist and co-author of the book Assault Rifle with Maxim Popenker, wrote an article in February of 2006 on the development of the Personal Defense Weapon and its ammunition, which he amended in late 2013. He includes in the article two photos which together represent one of the most complete collections of PDW cartridges I know of:

The .22 case design dates back over 150 years to 1845 when a Frenchman named Flobert invented the .22 CB cap. Some years later the case length was extended to make the .22 Short, then extended again to make the .22 Long and finally the load was modified to produce the .22 LR, 40 years after the original invention of the .22 CB cap. So what does this have to do with Memristors, and what the heck is a Memristor?

We got a chance to take a peek inside the new Surefire Ryder can. Two models will be available, one for .22 only, and another for .22/.17hmr. MSRP is 400 dollars for the dual purpose can.

The crazy people at Waterloo Labs developed a system to play the computer game Half-Life, a First Person Shooter, using accelerometers, drywall and a integrally suppressed Ruger MKIII.

Tam reminds us all that even though .22 Long Rifle is a weak cartridge, proper headspacing is still necessary. Case failure can be dangerous with any firearm / cartridge.

Wilson Combat have added a complete .22 Long Rifle AR-15 upper receiver to their AR-15 product line. It is in the M4 style with a quad rail, 16″ barrel, front flip up sight and a A2-style flash hider. The price will be $995.

The Target Cannon is a reusable reactive target designed to be used with .22 LR firearms or high powered air guns.

S&W are now selling a version of the .22 AR-15 patterned M&P15-22 that is compliant with Connecticut, Massachusetts, Maryland, New Jersey and New York law.

Over the past year Winchester have been doing a major update of their .22 rimfire product offering.

Remington have announced a new addition to their line of Model 597 semi-automatic .22 rifles. The VTR (Varmint Target Rifle) is styled after the AR-15 and features:

Crossman have licensed a gas piston technology and will be incorporating it into a range of air rifles. The word “gas piston” probably has you thinking of gas operated autoloader rifles. In the context of air guns, “gas piston” refers to the piston system of break barrel air guns. Instead of compressing a spring when cocked, they compress gas. When the trigger is pulled the piston is released, the piston is pushed forward by the expanding gas. The piston in turn compresses air which pushes the pellet out of the rifle.

Because of demand from customers have Federal have brought back the .22 Long Rifle UltraMatch Rimfire Target

The American Tactical Imports / German Sport Guns Kalashnikov has finally arrived. The Kalashnikov, endorsed by General Kalashnikov himself, is a AK-47 patterned rifle chambered in .22 Long Rifle.
