In time, we're going to have terrorist problems scattered around this country, rather than just concentrated in one place or another such as New York City or Washington D.C. By that time, additional restrictions may have already been imposed upon the armed citizens, especially in the category of so-called assault rifles. The government has already proven, time and time again, that they can neither prevent or efficiently respond to terrorist actions. Even worse, the current administration bites its tongue rather than even admit to obvious terrorism. So, we have a problem. It's brewing today, and will be on our table within a generation. With that being said, what do you recommend for both household defense and potential beyond-the-yard offense?
Yours is a perfect question, as we are sure that it has played in the minds of many who are capable of seeing beyond whatever sports event will be on TV next weekend. You've obviously noticed; while the majority of the country is passively asleep at the switch (only half of us even bother to vote in major elections anymore), we continually hand over our heritage to sub-standard thinkers (career politicians). To defend your home, have a dependable 12-guage shotgun close at hand. Loads should include some with shot in the No. 2 to BB range, some with large buckshot, and some rifled slugs. A full-cylinder or improved-cylinder choke will work best. My personal choice is a pump. It doesn't need to be one of those gussied-up creations with sights or vertical grips. Just practice with it from time to time to stay familiar with its characteristics. The rifled slugs will do a fine job of ignoring body armor.
For beyond the yard, we find that the balance, general handling, durability, and accuracy of the Remington 700 SPS Stainless to be about as good as anything on the market. If you prefer a different rifle, then choose it. Pick a chambering that shoots far accurately, hits hard, and has a ballistic advantage over the cartridges generally used by the military. The most commonly used cartridge with any power at distance is the 7.62x51mm Nato (308 Winchester), so think in terms of the 270 Winchester as a minimum. That Remington in a 30-06 is quite possibly more accurate than what Carlos Hathcock's sniping rifle was in Vietnam, and is an excellent choice. Personally, I choose to go even larger with the 300 Winchester Magnum and 210-grain match bullets, and that's why I favor the Remington. Its long action allows you to seat match bullets out further, which makes the round too long for actions that limit the cartridge length to 3.340". Some may prefer the 7mm Remington Magnum for their super-long-range choice. Don't over-scope. The Leupold Mark 4 in 3.5-10x40mm is all that's needed, and it won't spoil the balance and handling of the package.
As every Boy Scout knows; BE PREPARED. The advise of their motto is the best available.
