Problem: Article: You want to pick up the cleanest brass possible (though it isn't terribly important), but the main issues when picking up brass is collecting the correct caliber, making sure the brass is in good shape (literally), and it hasn't been reloaded too many times. Most rifle casings work just fine together. Common pistol calibers are a bit more picky as casings will wedge themselves in the openings of other larger caliber casings. .45s and 9mm work just fine with each other, but adding .40s into the mix will create problems. When cleaning .45s, .44 Magnums, .40s, 9mm, .357 Magnums, and 38 Specials all at the same time, clean the .45s, .44 Magnums, and 9mm in one batch, and the .40s, .357 Magnums, and 38 Specials in a separate one. You can test to see if casings work well together by trying to fit one casing into another, if it is even remotely tight it won't work. The easiest way is to use a vibratory case cleaner. The case cleaner uses a media to clean the case, and optionally you can use a polishing additive to make the casings look almost as good as new!  The media is usually ground corn cob or walnut hull, but liquid media is also available. The media is what makes the tight fitting cases stick in each other. When the media is not able to cycle (because it is jammed in a casing) it cannot clean as well. Note that the media is reusable, and less polish is needed every time you use the same media. Depending on how dirty the brass is, one batch of media may last anywhere between three and eight cleanings. This allows for easy access when loading so you don't have to pick up handfuls of random casings to find the one you want. It will speed up the process in the long run. Usually you place each different caliber into separate bags for transporting or storage.
Summary: Pick up empty casings from where you shoot or from a gun range which allows you to collect brass. Sort the casings, the level of sorting (before cleaning) depends on the calibers being used. Clean the casings. Sort the casings into separate calibers.

Problem: Article: Typically calls are made with either one reed or two reeds and a wooden, acrylic, or polycarbonate sound chamber that amplifies the sound.   A single-reed call has a larger range, both in terms of volume and sound control, but is a little more difficult to master in terms of technique. This would be a good option for the advanced (or at least experienced) caller. Double reed calls are quieter but easier to control and easier to vary in terms of sound. A double reed will require more breath, but is generally a better option for the beginner. Making accurate sounds is more important than volume and double-reeds have a reliable "sweet spot" that sounds very realistic. While the notable differences are few between the different materials that make up the sound chamber, knowing the subtleties will provide you with a good guide if you're planning on buying and a smart use when you plan to use them.  Acrylic calls will make a loud, sharp noise. These are useful for open-water and long distances. They're also very easy to take care of, extremely durable, and will stay clean in the elements, but are the most expensive option by far. Wooden calls make a soft and mellow tone that some say is more accurate. They're inexpensive, but more difficult to take care of, though they will last for a long time if you do. Polycarbonate calls are generally the same price as wooden calls and offer a sound somewhere in between the sharpness of the acrylic call and the softer tone of the wood. They're water-resistant and reliable. If you're going to be hunting on open water, or it's particularly windy out, you're going to need a call with a lot of volume. If you're going to hunt from a blind, or with decoys the ducks come right up to, it would be better to have a softer call that offered more finesse in terms of sounds. When you know where you're going to hunt, you can pick a smart call for the job. Talk to local hunters and sporting goods dealers to check out available calls and learn about popular varieties. Detailed instruction guides are available to guide you through the process of carving a wooden duck call, fitting it with reeds, and tuning it to the proper specifications. This allows you the option of customizing your call and designing it creatively. Cheap do-it-yourself kits are also available, but these are often low quality.
Summary: Choose between a single-reed or a double-reed call. Select between an acrylic, wooden, or polycarbonate call. Consider volume. Try  making a call.

Problem: Article: (If you're wearing a pullover hoodie, only put your arms in so that the hood is again in the front of your body.
Summary: Rip off a piece of paper, maybe about 5" by 5". Write all of the test answers, notes and any other important information on the paper. Tape the cheat-sheet into the hood of your hoodie on the day of the test. Put your hoodie on backwards, so that the hood is in front of you. Look at the paper, easily, whenever needed.

Problem: Article: If you need to travel backward, make sure the vehicle is at a complete stop before changing gears in or out of "reverse." Slide the gear shift to select the gear marked "R" and check behind/ around you for any possible obstructions. Gently remove your foot from the brake and place it on the accelerator. When turning in Reverse, your car will turn in the same direction that you turn the wheel. You're just going backwards, so the end of the car will swing in that direction, rather than the front. " The "neutral" gear is only to be used when you have no need to control the speed of your car, not when driving regularly. Examples of this include when idling parked for a short time or when being pushed/towed. The gears marked "1," "2," and "3" are known as lower gears. These can work as a sort of in-engine brake system when you need to save your actual brakes. Going down steep hills is a good use of this technique. 1st gear, however, is only to be used when you must go very slowly. There is no need to stop when shifting between these gears and Drive.
Summary:
Travel in Reverse. Use "neutral. Use the lower gears.
