The Right Gun for the Job
Home Defense: For protecting your home nothing beats a 12-gauge pump shotgun with the shortest legal barrel loaded with buckshot. The sound of chambering a shell alone is enough to make most intruders pee-pee in their pants. If you do need to fire on anyone the shot spread should be wide enough that you will not miss as long as the gun pointed in the same general direction as the bad guy. Buckshot is large enough to have the stopping power to kill a human on the first shot.
Bird Hunting: An over-and-under shotgun of the gauge of your choice can’t be beat. Some people prefer semi-autos, but I think that over-and-under shotguns are more accurate, less likely to jam, and you never have to worry about the game warden interrupting your hunt to inspect you gun to ensure it can’t hold more than 2 rounds.
Personal Defense: I suggest a snub-nosed .45 ACP revolver. The snubbed nose makes for a lighter, more easily concealed and drawn weapon. I say ACP instead of magnum because the snubbed nose will make the gun deafeningly loud, literally. People have burst their eardrums firing high caliber snub-nosed magnum pistols. Revolvers are superior to semi-autos for self defense because they never need to be pre-cocked with two hands. A simple thumb-cock or just squeezing the trigger will do. People are large animals, and you need significant stopping power to guarantee your safety when you shoot someone. This means big bullets that transfer a lot of energy. Therefore go with a .45.
Varminting: A .22 cal rifle provides all the power you could need for varmints without turning them into pudding. My personal favorite now that the assault weapons ban has expired is a Walther G-22 rifle with laser sight and scope, loaded with Stingers. This has to be the MANLIEST .22 in the world. Stingers are by far my favorite .22 LR bullet. I tested them against all lead .22 LR and magnums as well as the same bullets with copper jackets. I took a rifle and a box of 20 of each bullet out to a place where people do some illegal dumping. I chose an old stove as my target, and shot it up, checking the penetration and expansion of each type of bullet I used. The Stingers penetrated deeper and expanded more than every other bullet I tested. These bullets rock!
Big Game: I use a .338 magnum bolt action rifle. At this size you can shoot anything from pronghorn to elephants and get a kill without ruining too much meat. It has a long range so you can really reach out and touch someone with it. A bolt action rifle is both more accurate and more reliable than a semi-auto. Sure you can only expect to get one shot off before your target runs away, but if you hit with this rifle you won’t need a second shot anyway.
Fun: Can you say machine gun?
If Civil War Breaks Out: Again, can you say machine gun? Barring that get your hands on a .45 ACP semi-auto pistol or bigger so you have stopping power and a large clip size with fast reloading capability. Get at least a 30-06 semi-automatic rifle, but it would be better to stick with a .308. Now that riot shotguns are available a 12-gauge riot shotgun would definitely come in handy. Having trouble getting a machine gun? Buy any semi-automatic model of a fully automatic weapon. Go online and buy a trigger modification kit for that particular gun. Install the trigger mod. You can also take your gun to a local gunsmith. Some of them will modify triggers into full-autos. Now the world of real MP-5’s, Tommy Guns, CAWS, AK-47s, and the like is open to you. With all of these semi-autos and fully-autos there is one other you need to know. Do not waste your time with a gas operated gun. They jam easily. Stick with mechanically operated guns.
