Letter RE: Some Points About Pistol and Rifle Magazines and Their Springs

Sir: Over the years I, like all shooters, have heard theories on magazine springs and how to treat them. A few years back I took a tour of the Sandia National Laboratories and I spoke with a metallurgist who was also a shooter and he had some noteworthy insight on the issue. As he said, “if the spring was made of the right materials and heat treated properly, leaving it loaded will not cause the spring to weaken.” Leaving a spring compressed will not weaken it, it is compressing and relieving the spring a lot that causes them to weaken …


Letter Re: Assessment of Coach Guns?

Mr. Rawles; What do you think of the double-barrel coach gun as a weapon for less-frequent shooters? I’m thinking this might be a good choice to give to the older lady next door, or the wife who doesn’t shoot as a hobby. It’s easy to use (few controls), intimidating, and has manageable recoil, when used with the right buckshot loads and possibly a quality recoil pad. – John in California JWR Replies:  Coach Guns (a.k.a. side-by-side double-barreled shotguns or “luparas“) are an antiquated design, but they do fill a couple of useful roles in a retreat firearms battery. Their greatest …

David in Israel on Spices and Charcoal Medicine

Spices The original use for spices was to take out the funky flavor from spoiled food. As you remember, Columbus sailed in search of a shortcut to these spice which were considered a treasure on par with gold and jewels. Common sense will dictate how to stew, boil, or overcook foods to a safe level. Spices and salt will make this still nourishing food edible. Of course spices will be a valuable barter item if international trade is stopped. Charcoal Medicine Charcoal is a great first line treatment for loose stools. For example, a slice of bread burned over flame …



Letter Re: Poor Man’s Generator Power Transfer Switch

James, Anyone considering using a generator and transfer switch should give the following link a look: http://www.generlink.com. It’s an alternative to the most commonly used transfer switches and costs much less. When I called my power company about it they were not familiar with [this brand of switches] but studied the info on it and approved it for installation, they also offered to install it and said they would probably stock them for customers needing back-up power supplies. Regards, – Keith


Letter Re: Some Points About Pistol and Rifle Magazines and Their Springs

JWR – Recently had a few realizations about magazines (the weakest link in any semi-auto firearm): Even though I regularly rotate my magazines, I have discovered that the Glock G30 [compact .45 ACP] magazines have taken a set. [Their springs became weakened, under compression.] They are 10 round magazines, which I was only loading to 9 rounds and rotating every 30 days. While I ALWAYS download magazines to preclude the maximum compression of the spring from overwhelming the loading energy of the slide/bolt going forward, the extreme compactness of the G30 magazines is apparently more than the springs can take. …


Letter Re: Protecting Your Family From an Influenza Pandemic

Jim: [In your article on Protecting Your Family From an Influenza Pandemic] you mention: “Stock up on Acetominophen (Tylenol) and Ibuprofen (Motrin) as well – for treating fevers.” Some of us know that a mild fever is a good thing. [It is part of the] immune system response to fighting the virus. Aspirin is a symptom treater and can cause a virus to live longer in it’s host. See: http://survivalmonkey.com/forum/a-fever-is-a-good-thing-to-a-point-vt1842.htm?highlight=fever JWR Replies: Yes, a mild fever can be a good thing, but a high fever can cause complications. A high fever should definitely be knocked down quickly.  Hence my advice …


Jim’s Quote of the Day:

"Certainly one of the chief guarantees of freedom under any government, no matter how popular and respected, is the right of citizens to keep and bear arms. This is not to say that firearms should not be very carefully used, and that definite safety rules of precaution should not be taught and enforced. But the right of citizens to bear arms is just one more guarantee against arbitrary government, one more safeguard against tyranny which now appears remote in America, but which historically has proved to be always possible." Senator Hubert H. Humphrey (D.) Minn. "Know Your Lawmakers" Guns magazine, …



Army Upgrades Interceptor Ballistic Armor With New Side Panels

(Quoting the American Forces Press Service, Jan 10, 2005, by Jim Garamone) The Army will continue to improve body armor issued to soldiers, and will begin manufacturing side-panel inserts to the Interceptor ballistic armor (IBA), officials said here today.  The side panels, which weigh three pounds, will be made of the same material as the small-arms protective inserts. Army Col. Thomas Spoehr is in charge of fielding body armor. He said the Interceptor body armor now issued to servicemembers protects against most of the threats they face in Iraq and Afghanistan today. “It’s the best body armor in the world,” …


Letter Re: What is The Big Deal About Pre-1899s and 80% Complete Receivers?

Jim – I guess I am thickheaded and missing something here. What difference does a pre-1899 or a 80% finished firearm make? Are you trying to tell me that the jackbooted thugs of the ATF will stop, examine the rifle, determine that it is legally not a firearm, and not steal/confiscate it from you? Got it, no 4473/record of it, but neither is there one between private individuals either, so why pay $120 for a pre ’98 barreled receiver, when I can get a complete working Mauser for that? I’m not trying to be ugly here – just really don’t …


Letter Re: Truck, Auto, ATV, Motorcycle, and Bicycle Tire Repair

James, When I was in high school (in the early 1980s) I had no money and would find tires for my car by the side of the road. If it said E78-14 on the side and had more tread than the worst tire on the car, it came home. I could change a tire by breaking the bead using the bumper jack on my Sister’s Dodge Dart. Flip it over, break the other side. Remove from the rim with a pair of tire spoons that my Father had, then repeat in reverse to get the new tire on the rim. …


Letter From Rourke Re: Insulated Concrete Forms for Home/Retreat Construction

This is in response to a letter from B.V. (posted 1/12/06) on Insulated Concrete Forms (ICFs) and http://www.polysteel.com. As I said in my 1/7/05 letter, the major shortfall of this type of construction is the roof. Otherwise, this a good idea, in particular to insulate the concrete wall from the elements so it acts as helpful thermal mass for heating and cooling efficiency. Also, reinforced poured concrete is far superior to block, just try drilling through each sometime. There are several companies that make these systems. I happen like the hanger system (for joists and trusses, etc.), and the system …
