Can you imagine how hard it is to maintain a 500 yrds perimeter 24/7/365? Do you know how EASY it is for any modern hunting rifle to hit a man-sized target at 500 yrds? ANY politician giving a confiscation order paints a massive bulls-eye on his own forehead.
On that day, I plan on being one of those who suddenly isn't at home when they come to round us up. This is not a warning. This is not a threat. This is just what will be.
Not saying anything provacative...but I'm rather proficiemt at 300 yds with my 30-06...and have a LOT of 30-06 ammo. I won't be at home either.
