Yes I can make an air gun bullet which will perform beautifully. Best with a good flatnose if you want to take game.
I like your optimisum, BadNews, in believeing we may be able to use big air guns when they get the firearms from us, but all through history disarming meant everything more lethal than rocks and clubs and they weren't permited but only tolerated because they couldn't all be gathered up. - I have been in a fight with big brother who is trying to take me out of business for the last 9 years, but they ain't did it YET, and WON'T. All of you, please develope that attitude, and fight, even if you think you won't see tomorrow because of your stand. Tomorrow isn't worth seening if we are slaves. George Washington had a vision of what has turned out to be US history up to now and one more major battle, and the people won that last battle of his vision. My wife had an almost identical dream shortly after Kennedy was shot, but hers only showed that last war, and the people won, but only with the help God, which is exactly what George saw. Because my wifes dream was so vivid and clear, and showed her things she had to ask military people about to know what she had dreamed, we both believe in it strongly. The war against us is spiritual, against God and those to believe in Him. So pick that side and throw everything you have into it when the time comes. Just don't try to go out and start something on your own. Wade in to defend yourself and the countries freedom and call on God for strength. He will be there.
