.223 AR shooters

[browning204]

hey guys, a little help please.

For those yote hunters that use the AR, I have a question.

What distance and P.O.I. do you sight in your rifles???

The .223 has one heck of an arch during flight. I have been noticing that when dead on at 100 yards, it is high at 50 yards.

with 55 grainers.

Just trying to see where you guys sight in your rifles to be effective at all shot ranges.

I already lost 1 coyote with the .223 after being shot twice. I don't want it to happen again.

Thanks

here is the remington shoot program I like to play with

http://www.remington.com/products/ammunition/ballistics/remington_shoot_ballistics_software.asp

I like using this ballistics chart for quick reference-

http://www.shootingtimes.com/ballistics/ - under centerfire choose .223(then click the go button to the right, and it will open up a page full of .223 rounds/makers/ types


On the RemShoot-  after you apply ammo, set target and zero, shoot =)   there is A calculate tab in upper left, open it and go down to graph trajectory.  your cursor becomes A  +  and as you mouse over  the blue line and the readout at the bottom will give you the bullet path and yards.
                                                       
      With all that out of the way   With A 200 zero (24"bl) you shouldn't get more than 2" high, and -2"  is about 240yds.  Of course with A 16" barrel your losing about 6-7% velocity(can't remember what the experts said)- so if your starting out @ 3200 you're down to about 2975 right off the top.

   Sorry if this was choppy, trying to play with the program while I type this up!  I went with A 24" 1/12 twist to shoot 40-45 grainers ~KT

[browning204]

ya I have a 16" barrel. thanks for the info, I will try it out.

One of the shoot programs lets you change power grains, bullets, and so on. Not sure which one though.  I did have A sierra program, but not sure where it ran off to.

RemShoot also has A setting there for scope ht. , wind,  and different stuff.

      I prolly didn't help you very much, but maybe I'm baiting A real expert to come in here and explain! :roflmao:  ~KT

Hey browning I have a DPMS sweet 16 its a real shooter wiith my hand loads, but I came to the conclusion that 200 yrds is max for that gun, short and sweet they dont have much more after that they start droppin fast.Oh and I do have it sighted in at 200.

[cb223]

I have a 16" and a 20". I have them both zeroed for 200 yards.

So does that put you around - 1/2" at 50 Yards ??? ( on the 20" Barrel) and just for S&G  where does this compare to the 16" Barrel ???

I have a 16" AR zeroed at 100 yrds w/ a red dot. I've also zero'ed a 20" at 50 yrds. Not a whole lot of difference but I went with 100 in the end just because its what I normally do with my other rifles. The Sierra Reloading CD has a wealth of information on drop etc if you can get your hands on it.

  Hornady.com  has a ballistics calculator on it that might be helpful. Punch in your loads and print trajectory charts for anything.   Happy hunting

I've got a bushmaster with a 14.5in barrel (1 1/2in flash suppresor) and i use two different methods for zeroing depending on what range i may have an opportunity to shoot at.  First, we have the factory style of zeroing.  center your groups @25 yards and you will re-zero @300.  Seems like this method will provide you with two extremes as far as range goes. 

Then, we have my preffered method of AR/m4 zeroing.  I center my groups @50 yards with the theory that i will be hunting in relatively thick terrain where i wont hav to pull off a shot at over 150yards  (the field to my back  ) . With this done,  a 25, 50, or 100 yard shot will not have significant difference in its POI .  However, to overcome the problem with pulling off tight shots through small shooting lanes outside or inside of the 50 yards;  I practice and memorize 25,75,100,and 150.  Hope it works 4 YOU!!! good hunting, let me know if you try this

Hey there, I have mine sighted in at 100yds,  it shoots about 3 inches high at 10 yds.    But most of the shooting I do around here is under 150 - 200 yds, so that works out good for me.  Aaron

  To answer your question, i mainly shoot a remington 55gr hp.  For the purpose of cost efficiency and they have proven accurate and devastating when well placed.  I also use winchester supreme 55gr ballistic tips  (on special occasions)  These bullets are as vicious as i have seen for .223 as far as terminal ballistics and accuracy.  The only problem with the ballistic tips is that with any remotely rapid fire, the projectile is commonly forced back into the casing upon feeding into the chamber.  I think they were designed for bolt action rifles.  But none the less,  Accurate and VICIOUS. 

     I also just started experimenting with 55gr remington soft points.  I'll keep you posted on their perfomance.

I use V-Max in my AR-15 and I have NEVER had ANY Problem with any Ballistic Tipped Bullet and I hope I NEVER have a Problem with them  especially since I MIGHT order 500 of the 50 Grn V-Max for My AR-15 and My youngest Sons 223
About the not affording to reload your own Rounds,,I just seen 2 Post's on another Board from Remington AND Winchester saying that ALL Remington Ammunition is going up by at LEAST 15% at the end of July or August and also that ALL Winchester Ammunition is going up at LEAST 15% By the END of September !!! so ya MIGHT want to "Roll your Own" Ammo here pretty soon,,Of course Reloading Components are ALSO going up in Price,,pretty soon ya wont be able to Shoot your Guns because of Ammo Prices  ah Hell,,EVERYTHING is going up in cost and one of these days the SHIT WILL HIT THE FAN !!! I probably wont see it BUT My Grandkid will and he is Only 7 years old  BUT Until that day I will keep

aaahhh hheeeelllllll    This is unreal.  i sure hope there's no problem with my AR  :shck:  Naaaa, there couldn't be.  I bought something like five boxes of the win. supremes from this little old gun shop in Maine.  I pray that i had a bad batch and thats all.  Ya know,  I always wanted to "roll my own" rounds.  The owner of my club might have some equipment floatin' around.  I really appreciate the heads up

So you shoot v-max through your AR?  I don't know much about the rounds and was sceptical of the coating on the bullets.  Would they have any negative effect on the chrome-lined barrel?  Also, How do they work 4 you?

[ohiobob]

Nate
When you say Coating on the Bullet,,are you talking about the Moly Coat ??? I have NOT shot any Moly Coated V-Max through my AR-15,,BUT I have shot the 50 Grn Moly Coated V-Max through my Parker-Hale 22-250 and I have NOT ever had a Problem with them  BUT I do have 100 Moly Coated V-Max in 55 Grns that I may have to load and shoot through my AR-15  The Moly Coating does not Bother me,,everything I have shot the Moly Through and cleaned came very Clean,,BUT I prefer to have the Non-Moly Bullets,,thats just me though 
Bob

[bushmaster]

Bob

    Yeah thats what i was wonderin' about.  I've heard some people at the gun club talk about the moly-coated rounds to be no good for chrome-lined barrels.  Let me know when you shoot em through the old AR

Nate
I sure will let ya know  I got the 55 Grn  Moly Coated V-Max and a 1 Lb Can of Varget for Fathers day,,I THOUGHT about taking the V-Max back and trade them in for NON Moly Coated Bullets,,but then I figured,,ah Hell,I will just shoot them in the AR-15 and Just buy more 50 Grn NON Moly Coated V-Max for the other Rifles,,I am THINKING of Buying 500 or a 1000 of the 50 Grn V-Max,,and then getting 1000 FMJ's Strictly for the AR-15 on "FUN" Days 
Now all I need is to get the Neighbors in Gear and let me know what kind of Powder and Primers they want 
Bob

P.S. Browning204,,did you ever sight your AR-15 in with ALL this Advice ???  and do you have access to a Chronograph ??? I have one BUT I haven't shot any of my NEW LOADS through it yet  I need to get my ass in Gear !!!

[bushmaster]
