Well, not near as far as some of you shoot, but a personal best for me at 535 yards tonight with my Sig SSG 3000. The groundhogs have been hammering the new bean fields that are just starting to sprout, and tonight I hit it just right. They were coming out of the wood work. I had some issues at 490 yards for some reason with my dope, still not sure what was going on, but I continued to miss some small ones that were coming in and out of their holes.
Later on this one came out and I checked the wind one more time, dialed the elevation in, held a mil off for wind and squeezed off. He never moved. Man I love varmint hunting.
