How do make 360 yard shot with rifle on ten inch plate??
Well, in order to try and build the same sort of familiarity, skill and comfort with longarms that I currently have with handguns thanks to regular competition, I have resolved to participate in a local USPSA 3 gun match on Saturday.
However, I learned that there will be a 360 yard rifle shot on a ten inch plate in this competition.
Holy cow! I have hardly ever taken a shot at that distance seeing as I'm used to pistol ranges. How the heck do I make a shot like that?
I plan on taking my A2 style AR 15 since obviously I'll need a lot of accuracy for this event.
A friend helped me to set my irons on that rifle for 100 yards. Just last Saturday he showed me how when shooting atba close target I actually have to aim high because of the position of the sights relative to the barrel.
I surmise that at 360 yards I'd also have to aim high if I'm sighted in for 100 yards. Is that correct? How high should I aim?
If I make the shot I'll be able to tell everyone I learned how to do it on the internet...

It's been awhile since I shot a M16A2 but I can give you some advice, I shot expert in the Corps. You need to practice at the range in the position you plan on shooting first. The A2 style sight adjustments are pretty easy to make. One click here and there and you are on target.
If it is standing I would get my natural aiming down first. I do this by aiming then closing my eyes taking a breath then opening again to see where I was aiming. Then move my front foot left or right and repeat till I would be on target after opening my eyes. Move your body not the rifle.
Clear front sight tip then put the sight in the middle of the blurry target.
I could shoot a 4 inch group at 500 standing. Which pissed one of my Drill Instructors off.Judo is only gentle for the guy on top.

For a 360 yard shot you'll have to aim low if you're zeroed for 100 yards. If I recall you'll be aiming low about two plates. On silhouettes you aim at the base of the target and hit about center mass. Keep in mind this is all an estimate.
Is the shot resting, standing or kneeling?

Depending if you took a standard 25M BZO with your gun or if you sighted it in at 100, it's really going to depend. A 10" plate is a HUGE target...even at 300 yards. You should have no issues. If you have a standard A2 upper (carrying handle style sight), you can copy/print out your standard military-style BZO sight-in target and the ballistics for such weapons (depending of course, on barrel length) are readily available online. You can either hold over/under or you can simply add the requisite number of clicks (remembering of course to undo whatever you "do", when you're engaging targets closer).

Wow, thanks for all the info, folks.
I'll do my best this Saturday, maybe aiming low, and then I'll go ahead and fool around learning about zeroing, so hopefully next time I'll feel more confident!
I am not sure if the shot is standing, supported, kneeling or what. But as a n00b, I'll feel no shame in going prone if I have to, as long as that isn't against the rules. :P

Depending on the ammo, your average civvie 223 is gonna drop about what? 4 inches at 300 yards. If your good at kentucky windage you can simply adjust your POA by that amount without dialing in your sights. Takes knowledge of your rifle and consistancy with your ammo usage though.

Position yourself so your aim is naturally on target.
Breath in, let some out, stay relaxed and squeeze the trigger. Standing, I like to pull off the round as the muzzles lowers onto the target.
10 inch target at that distance is no problem.
4" groups at 500 yards standing is some fantastic shooting. Hell, that's good shooting from prone with the M-16.Carter Hargrave's Jeet Can't Do

With an M16 500 yard shots are impressive period let alone 4'" groups. Beyond 350m the sight post is bigger than the silhouette of a full size man.

The competition was called on account of rain. :(
That's okay...I guess it just means I have more time to practice and learn one end of a longarm from another.
Thanks again to everyone for all the advice. I hit an indoor range this morning and attempted the 50 yard zero, since the competition was called.

Are you using a 20" barrel or 14.5/16" ? I'm assuming the latter unless otherwise stated?
Are you using a mil spec rear sight with adjustable windage and elevation, or a back up style/flip up with no elevation adjustment?
For rear sights with adjustable elevation, I personally prefer the revised improved battle sight zero, which requires that you "reset" the click where your elevation bottoms out. By doing so you get a bottomed-out 100 yard (or meters if you prefer that) zero, with the original bottomed-out setting now being a 50/200, while maintaining your normal 300, 400, etc settings. You can find instructions on the net of how to do this, it's easy and just requires an allen wrench. Or find someone local that can show you, or just ask if you have questions about it. It takes almost all the guess work out since your point of aim is generally never off your point of impact by more than about 2 inches assuming your elevation is properly set for the distance.
For non adjustable elevation, I would normally recommend a 50/200 for practical purposes, but if you are specifically having to shoot at 360 yards for competition, assuming you have no targets in about the 100 to 300 range, I would recommend 25/375.
The reason is that with a 25 yard zero, your point of aim and point of impact are nearly crossing at 360 yards. With 50/200, you have more than 10 inches of drop at 360, which is larger than your target. However, pretending I was shooting a competition and for whatever reason did not have a rear sight or optic that was either adjustable for elevation or did not have elevation markings, and if that competition had targets at, let's say 100 yards, 250 yards, and 360 yards, I would probably go with a 50/200 because my point of impact on the 100 and 250 yard targets would be within about 2 inches of my aim on the 10 inch plate, with me having to adjust for 10 inches of drop on the 360. Conversely, under those same conditions with a 25 yard zero, I would have to adjust significantly on two targets, holding low on the 100 (impact about 6 inches higher than aim) and on the 250, with the difference on the 250 being a 10 inch difference between aim and impact.
Wetware, unless I'm reading the post wrong, you have it opposite. A 100 yard zero will drop by about two feet at 360 yards, so you would be aiming very high.
