I have a chance in two weeks to go hunting for coyote on some farmland where the guy pays per head to get rid of them. I have a shooting range in which we have a 100 yard target,, but he states that most of the shots for the hunt will be around 200 yards or little more... anyone have info on how high my shot would have to be at 100 yards to be on at 200 yards?? thanks in advance for any help. FYI I will be using reloads with 69 grain nosler competition hp bullets.
 
It's impossible to say without knowing the type of gun, barrel length....and how that works with the ammunition you mentioned. You didn't say if and at what distance your gun is zeroed at. If your gun was zeroed at 100 yards, you'd have to then go shoot at a 200 yard target and see how much drop you get below your POA. If you were zeroed and 100 yards, depending on your gun, barrel length and ammunition, you'd probably be looking at around a 2 to 4 inch drop going out another 100 yards. The only way you're going to know for sure would be to go to a rifle range with your gun and the exact ammunition you'll be using....get the gun zeroed for 100 yards and then see what kind of drop you get if you shoot at 200 yard targets.
 
Hornady has a trajectory calculator on their website. Try that. In general, set 1.5 - 1.7" high at 100. You'll be close at 200 and 7 - 9" low at 300.
 
Tkx for all replies... I know there are alot of variables that I failed to meantion... I was just looking for a rough estimate... I figured 2inches high at 100 yds... thats what I will try for now...
 
If you are already zeroed at 100, I you should be close enough at 200 to still hold on hair and get hits. I would prefer to actually shoot my guns at all ranges I anticipate so I know exactly where it would hit. But realistically with most modern rounds they don't drop that much between 100 and 200.
 
I zero pretty near all my hunting rifles for 2" high at 100 yards. That, way, they're all about dead-on at 200 and around six inches low at 300 (no magnums).

With my .223, that's fine for prairie dogs to 300 yards...
 
Loaded some ammo tonight... got freshly processed brass, cci primers, Ram-Tac @ 24.5gr, 69 gr hpbt nosler competition bullets..backup 44mag, Buck 120. Supposed to hunt two weeks from tomorrow. The landowners nephew is going to take me out the first time to show me the ropes. The big man is paying fifty bucks per head to shoot em on his property.:D Ive always wanted to shoot a 'yote.

Nice looking gear, I like TAC too. Hunting in the East many shots at coyotes are on the shorter side. Of course it depends on the specifics of your area. They also don't hang around long to pose for the perfect shot. I'd make sure you can handle the 50-150yrd shot 1st. Watch you scent,noise, & movement getting into position, good luck.
 
1.5-2" high at 100 yards should be pretty much spot on at 200 yards. Most high velocity cartridges are in that range with a 200 yard zero. I'm with Art Eatman. A rifle intended for most hunting conditions should be zeroed 1-2" high at 100 yards. I really don't understand why some people like to zero their rifles spot on at 100 yards.
 
The Army Marksmanship Unit use to put on sniper schools for Police Departments (including the FBI before they got their own program). Their recommendation for urban sniping/counter sniping was a 223 bolt gun with a fixed 6-8 power scope.

They recommended zeroing the rifle at 250 yards, the ideal being that you can make head shots up to 300 yards. This was with the M193 55 gr ball or similar bullets.

Thats the way I set up my rifle in LE and it works. You sight it in for 250 yards I think you'll be able to get any coyote at reasonable ranges. At 400 yards you're only gonna be about 15 inches low so just have a tad of daylight above the critter and you'll nail him at that range also.
 
Good info here.
Be sure to take a camera and a range finder or GPS. It's always cool to post pics and distances and such of your successes. Good luck and have fun!
 
Trouble is, kraigwy, that military stuff doesn't really apply to hunting critters. "Somewhere in the head" isn't good enough for a clean kill on a coyote. And it surely isn't good enough for prairie dogs.
 
Having trouble getting a good pattern at 200 yds... Have replaced the Bushnell scope with a Konus. Ive had pretty good luck with them. When I did adjust my shots 2 inches high at 100 yards they were then aprox 6 inches high at 200 yards.

That's pretty odd.

If you have a 200yd target then you might want to re-zero on that target.

What type of groups are you getting at 100 and 200? Hopefully you're under 4" at 200yds.

Sorry to say this might have been a case of the perfect being the enemy of the good.
 
Buzz, a quick question about sight-in height in the hunting forum is fine. But when it shifts to problems in point of impact, this isn't the forum for it, and it's a drift off topic. :)
