You might also go to one of the large gun shows in your area and check on some of the Israeli Military surplus ammunition. Usually in cans! I have shot it and it always worked well! There are other good 7.62 (308) military surplus ammunition also that is good for stocking up! Some here on the forum will add others that are good to the list from experience!
The Constitution is not an instrument for the Government to restrain the people. It is an instrument for the people to restrain the Government!
Today, we need a nation of Minutemen, citizens who are not only prepared to take arms, but citizens who regard the preservation of freedom as the basic purpose of their daily life and who are willing to consciously work and sacrifice for that freedom."
