Letter Re: The PTR91 Rifle

Dear Mr. Rawles: In a past life I used the popular HK MP-5SD. It’s reliability prompted me to purchase one of the first PTR-91s directly from the manufacturer. (Back when that was possible–they are all now sold though distributors). I found the PTR-91 capable of digesting a wide variety of ammunition thanks to the HK family of well designed roller delayed blowback systems. This functional reliability and availability of really cheap magazines indeed make it a popular battle rifle. What I haven’t read by those singing it’s kudos, is that the forcefulness of the extraction system throws the brass quite a distance, …


Pat’s Product Reviews: The PTR91 Rifle

In 1987 at a Colorado gun shop’s “Going Out of Business” sale, I purchased a brand-new HK (Heckler & Koch) Model 91 .308 battle rifle. I got the rifle, along with 10 brand new spare magazines, 1,000 rounds of ammo, a bipod and carrying case for the gun – for the combined price of just $600. Oh, for the good ol’ days! Today, you’ll likely spend $2,500 just for an original H&K Model 91 – and they are now hard to come by. A wave of stupidity overcame me one day, and I sold my HK91 to my friend, and …


Pat’s Product Reviews: AK-47 vs. AK-47 vs. AK-47

I’ve received quite a few e-mails from SurvivalBlog readers, asking me to write an article on AK-47s. Well, here’s my take on the AK line-up. First of all, I only write about guns I actually own or have personally tested. I don’t take a press release and write an article based on that, like some writers (that I’ve heard have done.) There are so many different variations of “AK-47s” out there these days, it would cost me a fortune and a lot of time, to obtain samples of ’em all to test and evaluation. The question always arises, which is …


Letter Re: The MGI Hydra Multi-Caliber Rifle

Mr. Rawles-   I continue to enjoy your blog.   I read with interest Pat Cascio’s review of the MGI Hydra rifle.  I can think of a one very good scenario where such a system is very valuable:  In a political environment where licensing restricts the number of guns that one can own.  The Witness brand semi-auto handguns are popular in Europe for this very reason.  One receiver can support several different caliber conversions.  Unfortunately, those same places usually take a dim view of private ownership of AR-15 style weapons platforms, so other restrictions may prevent ownership in any case. …


Pat’s Product Reviews: MGI Hydra Modular Rifle

Update, October, 2011: This review has been updated to NEGATIVE. To explain: In my original review, I had posted favorable comments on the MGI “Hydra” rifle system. I am withdrawing that positive review, and alerting SurvivalBlog readers to NOT purchase this product. While the sample I wrote-up in SurvivalBlog worked flawlessly, I have been informed of some serious quality control problems with current production Hydra rifles. Several SurvivalBlog readers who placed orders have received defective guns. One SurvivalBlog reader, after many months, finally did get a working Hydra. Another SurvivalBlog reader is still waiting. He returned his Hydra before he …


Letter Re: Ammunition Storage and Do-It-Yourself Desiccants

Hi Jim.   Dry wall is made of Gypsum, which is composed of Calcium Sulfate Dihydrate, with the chemical formula CaSO4·2H2O. It is found naturally and also made Synthetically by Flue Gas Desulfurization at some coal-fired electric power plants. Synthetic Gypsum can be used interchangeably with Natural Gypsum in some applications. There was a problem with drywall from China which contains too much Sulfur probably from the flue gas desulfurization process. When Water is absorbed by the bad drywall, Hydrogen Sulfide is formed which induces corrosion in some metals. I would not trust using drywall as a desiccant for ammo storage. Just think …


Two Letters Re: Ammunition Storage and Do-It-Yourself Desiccants

Hi Jim,   I wanted to share with others of how I make my own desiccant packs. Go to a craft store like Michaels and in the flower department you can buy a box of silica gel that is used for drying flowers. I then get a box of family sized tea bags (these are twice the size of regular tea bags but any size will work) Use needle nose pliers to remove the staple that holds on the little piece of cardboard used to squeeze the bags, empty out the tea and use a spoon to now fill the …


Three Letters Re: #10 Cans for Ammunition Storage

Hi Jim,   For some time now, I’ve been using spare food-grade oxygen absorbers with my long-term ammo storage in regular ammo cans. I keep a regular supply of O2 absorbers in a Mason Jar that I re-vacuum each time with the now famous Alvin Vacuum sealer / Tilia Mason Jar Adaptor.   Being able to stack ammo cans is also good. Seeing the sides of the cans squeeze towards the center (and hard to re-open): Priceless. This is one of the reasons why 5.45x39mm Russian is my favorite MBR round: The surplus Soviet ammo is already delivered that way! …


Letter Re: #10 Cans for Ammunition Storage

Mr. Rawles,   I have searched your site and others for detailed information on long term storage using sealed #10 cans.  Are there any drawbacks?  I can buy cans from the LDS cannery for around 1.00 a piece, which is much cheaper, by volume, than regular ammunition cans.  Any information you or your readers could provided would be greatly appreciated. – John S. JWR Replies: The #10 steel can is awesome! For food storage, they don’t suffer from the gradual oxygen transmission (permeability) weakness of HDPE buckets. For ammo storage, they work nearly as well as military surplus ammo cans. But …


Three Lessons from Russian History, by R.M.B. in Tennessee

I returned to the United States in 1999 after spending an extended period of time in Russia. The country has a deep, fascinating and sometimes terrible history. However, of moment to this submission are three events that, in my opinion, are very beneficial for each of us to consider and contemplate as we go about our business of preparing. These three events are so significant because I believe that these events are illustrative of what may occur in a SHTF or TEOTWAWKI scenario. By examining what actually transpired in a modern first world civilization during times of SHTF/TEOTWAWKI we can …


Reloading On the Run, by David L.

Your house might be secured. In your basement or workshop you have your reloading outfit, your press, your scale and all of your dies. You can load thousands of rounds in a couple of days if you choose. So what if you have to leave your home in case of the proverbial excrement hitting the rotating circulating blades? How will you pack up your reloading outfit? How much ammunition can you possibly carry if the need arose? Ammunition runs out, especially if you can’t get to the store to replenish that supply and you are away from home.   In …


Letter Re: Seeking Advice on Household Moves with Firearms and Ammunition

Sir, What advice could you give for moving one’s store of firearms and ammo a considerable distance in a relocation within the continental Unites States?  I am in one of the reasonably free northern New England states and figure that if I can make it through New York state without being stopped I can breathe a relative sigh of relief.  Still, I envision a scenario where the vehicle with the supplies is never left unattended.  And if I had to make this move alone I would consider doing so in a motor home so that I would only have to …


From Cartridge to Target: A Bullet’s Flight and Impact, by HardWalker

Lots of care and time are taken to select the appropriate firearm. A precisely crafted piece of machinery primarily designed to do one thing, send a chunk of metal downrange and high speeds with the intention of killing someone or something. There are many ways of doing this and many types of bullets designed for many different purposes. We all can gather the hearsay of what round is the best, which manufacturer has the furthers traveling, hardest-hitting or bang-for-buck ammunition. So when it’s all said and done, understanding what happens to that piece of copper, steel and lead once it …


Protecting Your Firearms Investment, by Grey Knight

Survival is a mindset.  The most valuable item one can have is knowledge.  One area of preparedness that gets reams of attention is the firearm.  The debate over which type, caliber, and capacity is endless.  Some of this is based on opinion, while other on experience. Yet with all the hoopla about the importance of firearms and ammunition, you never see much about care and cleaning.  I’m not going to throw my hat in with the hundreds of “experts” on firearms out there in the preparedness community, but I do want to talk a little about the importance of protecting …


Letter Re: Cold Weather Patrol Tactics and Techniques

Dear JWR: Regarding the recent Cold Weather Patrol Tactics and Techniques article, just one note about condensation prevention from bringing a cold weapon indoors. Packing or leaving a heavy duty garbage or similar bag outside and placing your weapon inside the bag can greatly reduce condensation from the indoor climate. Just place your weapon completely inside the bag. I like to compress the opening in my hand like a balloon opening and instead of blowing into this opening, I suck as much air out as I can with my lungs. If two or more deep inhalations are required to remove …
