I do try for shots at 1000 yards, but these days I'm still working on trying to be proficient at 650 and 700. I'm good at 500 as long as the wind isn't completely out of control, and them I'm marginal.
Save milk jugs, and nail those bad boys at 500 - 700 yards. That's a serious challenge at first, and then a fun challenge to hone skills. I keep shooting, and keep moving the targets back, and keep doing close up stuff, and somebody I'll be able to shoot 1000 very well. Maybe five years from now.
If I could shoot 1000 yards tomorrow, it wouldn't be any fun to finally know you've become an accomplished 1000-yard shot.
with this practice, I have killed more than 20 coyotes out past 500 yards over the last few years. probably twice that number inside of 500 yards, and one inside of 10 yards with a 9mm sig. There's an overpopulation at my in-laws ranch in northern idaho.
More than a few times I've shot at the yotes out past 500 and for one reason or another (me, wind, range, bullet, rain, snow, me again) the round misses and the follow-up shots have to be done while the beast is running. I have hit two on the run (yay!) both shoulder shots, but if that first shot isn't right, mostly they will get to some cover. Sometimes they stop and look right before they go into the trees, we are usually ready for that and BOOM, wait for it, wait for it, splat.
I'm doing this with a sako 30'06, but I have borrowed my dad's CZ in 300wm and his sako in 300wsm. my uncle long range habit is with the 300 rum, and he handloads his stuff and is shooting under five inches at 700 yards. It's impressive. I will get there eventually.
