zeroing a scope on a AR

[coltn46920]

I have a spikes tactical midlength 16" upper flat top with a Barska 6-24x42 Varmint Riflescope & 18-36x45 Blackhawk Spotting Scope Combo http://www.natchezss.com/product.cfm...odID=BKDA11414 and a burris AR-P.E.P.R Mount http://www.burrisoptics.com/arpepr.html

My question is when changing shooting distances do I have to constantly change my settings? So if I'm shooting at 20 yards then shoot a target at 100 yards I have to readjust my settings? Or is it the further I zero my scope at between that distance and 1 yard I'm zero'ed in at? So If I zero in at 100 yards between 100 yards and 1 yard I will be dead on accurate? Or does Parallax come into play at a certain close distance? Say 25 yards and closer?

I would start by reading this to learn about zeros and trajectories: AR-15 Zeros and Trajectories

Dude, you just asked this question last week, coupled with your "I bought super cheap free float rails, will they help me shoot better?" question. Do you actually want to learn this material or do you just want people to spoon feed you the most narrow of tidbit of info as it relates to the most pressing and newest concern that you have.

I highly suggest that you read the link above that Omega posted, along with http://www.snipershide.com/forum/ubb...812#Post378812 That thread's OP gives you links to 14 other threads that has just about all the info you could possibly need about scopes.

Read the info provided in the links, absorb it, use some common sense and critical thinking, that is the best way. You will retain the information.

+1.

We keep seeing the same threads by the same people, just worded slightly different. And they all end up in the Centerfire Rifles Section for some reason, no matter what they're about!

I think the guy's just doing what he can with the funds he has... I'd love a $2000 nightforce scope, but I'm broke as hell. So I too, have a cheapie Barska on my .308, because that's what I can afford in the meantime.

Being a newbie with a ton of "dumb questions" myself, I feel like I must stand up for our friend Coltn a little bit. I do agree that pretty much all the info you'd need can be found on this site, it's just a matter of finding it and knowing what you're looking for, which can be confusing to us beginners, trust me. I've spent hours pouring over webpages describing MOA, ballistic coefficients, barrel harmonics... and I'm constantly thinking of new questions, even though I've dedicated a lot of time to reading and learning.

Hey, I'm not knocking the guy for his equipment choice if he is living within his means. What I do take issue with, and I'm probably not the only one, is that asking the same question multiple times, and when people take the time to give good answers and try to be helpful the responses fall upon deaf ears and the question just gets repeated over and over again.

I wholeheartedly agree that there is insane amounts of information out there regarding every facet of our sport, however one must put in the time and effort like everyone else and attempt to do the research themselves and find the answers on their own first before asking, especially when the answers are so easy to find.

I am more than happy to help those who have done due dilligance in trying to learn the answers for themselves, sometimes you just can't find the answers, I get that. But agrivation sets in when that information is discarded so rapidly.

Fair enough.

As far as answering OP's question, I also recommend the posted link. I learned a TON from that one when I first wanted to reach out past 100yds, and become more precise under 100yds.

I have to backtrack and find that thread you started with the sme question that rero360 is talking about, OP did'nt get much response so I guess he thought he can get response from others if he starts a new one with the same Q asked in a different manner.

Anyway, OP to answer your question. Yes, if you zero your scope at a certain distance, you NEED to adjust your setting. Scope is just the same as iron sights. Look at the graph shown by zman, If you zero your scope or your irons at 25 yards, when you shoot at 100 yards, your shots will be 6" high.
You need to learn the hold over technique if you dont want to adjust your dials. If your scope has those markings or dots like the multiplex or mildot sights, learn how many dots or lines it would take to bring your shots to where you want it.
As an advice, zero both irons and scope at 50 yards. With irons, your shots are still close to POI from 25 to 250 yards, as for the scope, as Ive learn the holdover and you dont need to adjust the dials, unless you want to be precise.

One more advice, if from your other thread you said that you cannot even hit an 8" circle target at 25 yards? figure out whats wrong first before you worry about scopes, if you cant hit at 25 yards with irons, either your rifle is not zeroed or the problem is you.
