sscoyote... yes indeed. My 1000 yard rifle is a custom .300 Dakota with a 26" Lothar Walther barrel on a Mauser action. I use a real good Leuy 6.5-20 with target turrets and a 20 MOA base for that and it works well. I'm using 210 Bergers and 208 Amaxs and they really shoot nice. I've shot as tight as .700 at 500 meters (542 yards) but normally see around 2 inches at 600 yards. That rig has shot as well as a 3.5 inch five shot group at 1000 yards but I have a real tough time finding a place to shoot 1000 yards in Georgia. I shoot it slow at 2850 fps for accuracy (I'm a little sensitive to bone crushing recoil so I just putt along slowly when I am not in a hurry).
I'd like to have one of these nice new scopes on it but I have to have 20x or better and zero paralax and that gets a little pricey for me at present. I just bought a Nicon Monarch for my 30-06 hunting rifle and am anxious to try their BDC reticle to see if I can get that thing shooting well at 600 yards.
I'm hoping to spend two weeks in mid-Febrary coyote hunting in South Dakota if we get some snow. I'll use a 25-06 in Rem Sendero with a 6-24x50 4200 Elite. I'm still testing new bullets but expect to use a 90g monometal at 3600 fps to tap them out to 600 yards pretty well. I've had good success with the Sierra Game Kings in that, having taken a 500 yard antelope easily with that rig a couple months ago.
I'll also take my Bushmaster Varminter on that hunt where it looks like I might call in multiples. That thing is mucho deadly. I use a 6-24x56 Millot Buck Gold on that and it shoots 2 inch groups at 500 meters all day. The only difference is that it can spit out about one well aimed shot per second... its just too deadly on coyotes to make it a sport.
