Q: Most scopes should have two dials on it, one on the top and one on the side, which are used to adjust the scope and will allow you to zero it, so what you're seeing and where the rifle is aimed will be in line. The top knob is used to adjust the up and down of the cross-hairs, and the one on the side will adjust the scope left to right. On some older sights, you'll need to use a penny or a small key to turn the knobs gently, though on most sights you can just use your fingers to twist the knob, like a dial. If you missed high, adjust the scope to go higher. If you missed left, adjust the scope toward the left. Continue making the necessary adjustments until your secured and steady rifle is hitting bull's eye regularly, then move elsewhere on the range to try from another distance. On most scopes, each click you turn either dial that moves the zero 1/4", so four clicks of the knob would be about an inch. Read the user manual that came with your scope to be sure about adjustments, but always move little. If you have access to a laser bore sighter that will save you a lot of ammo and less wear on the shoulder. If not, take your rifle it to your local sporting goods dealer and have them bore sight it. It's a very inexpensive process that will result in a pretty accurate rifle. Once the gun has been bore sighted and is ready to shoot you should still test it yourself using these directions and make the necessary adjustments. Some difference will come from different user variables.
A: Examine the adjustment knobs. Move the sight toward the misses. Make very small adjustments. Use a bore sight for more adjustments, if necessary.

Q: Take safety precautions before using a grinding wheel. Polycarbonate safety goggles protect your eyes from stray sparks and metal fragments. Also put on ear muffs to block out the machine's noise and a respirator to avoid breathing in dust. Steel-toed boots are also a good idea. Wear these in case you drop a heavy piece of metal. To test the metal, you need some sort of spinning wheel. The faster it rotates, the more sparks it will produce. Get a bench grinder or handheld grinder with a 24-grit carborundum wheel and wait for it to spin up to speed. Hold the ends of the metal in your hands directly in front of you. Keep a firm grip on the metal as you lower it onto the wheel. The contact produces sparks, which you should be able to see without moving your head. Adjust the metal's position until you get a clear view of the spark pattern. Maintain a light amount of pressure on the metal as you watch the sparks. Steel produces sparks that branch out into about 5 yellow streaks. All the streaks are different lengths. The ends of the sparks fan out into tiny branches or "leaves," like on a tree. Search online for a visual aid by searching for the steel spark test. Both wrought iron and stainless steel produce long, even yellow streaks. The leaves on the end are smaller in stainless steel sparks. Steel made with less carbon produces yellow sparks with different lengths. The leaves on the end fan out more with a lot of extra little branches. Steel with high amounts of carbon produce sparks that begin spreading out near the grinding wheel. The sparks are duller or even red and fan out less at the end. Some metals, including nickel and aluminum, produce few or no sparks.
A: Wear goggles and other safety gear. Turn on a bench grinder. Hold the metal flat when pressing it against the wheel. Note if the sparks branch out in a pattern.

Q: Falling from a window is an extremely quick process, especially if it's only from the second story. The first thing you should do is stay calm and think quickly. You have only seconds to increase your chances of survival so it's crucial to act on your toes. The best way to survive a fall is to avoid hitting your head. People who land on their head almost always die, even if it was just from a few stories. While landing on your feet can sometimes cause pelvic injuries, it is a much safer bet than landing head first. Keep your legs and feet tight pressed against each other so that both of your feet hit the ground at the same time. If you find yourself falling out a window head first, try to quickly reposition yourself so your feet will be the first thing to hit the ground. A fall from a second story window takes only seconds so you must act quickly. If you are trying to escape from a window and you can avoid jumping, it is best to hold onto the windowsill or ledge, lower yourself to arms length, and drop from there. This will shorten the distance between you and the ground and therefore, reduce the impact. Before you fall, push off a bit with your feet and hands to make sure you clear the wall.
A:
Think quickly. Keep your feet down. Lower your body.
