Sight in distance for ar15 .223 for Prairie Dogs
 
 


This was my first time for shooting dogs.
I have a AR15 RRA A4 Varmint in .223.
In the 1st Issue of Varmint Hunter Magazine had an article on Prairie Dogs: "Practical Sighting Strategies for Prarie Dogs."
In this article it advises for a moderate velocity cartridge, which the .223 falls into, it recommended to sight the gun 2" high at 100 Yards for a 225 yard sight in.
My question is that the sight height for this rifle is 2.6" not the usual 1.75".
I used the Hornady Ballistics calculator, it shows that for this sight height it should be 1.4 " high at 100 yards for a 225 yard sight in.
Do I forget about the sight and just sight it in at 2" high at 100 yds?

Thank you in advance for any assistance in this matter.

Jeff B.

AR15 .223 sight in @ 200 yards for Prairie Dogs
 
 


Dead nutz on @ 200, and your "Point to Kill" range is yours out to 300 yards w/ 69 grainers. Mine was with a 24" barrel, yet this is also what worked for me as it had in the past. You gott'sta try it out and see for you. What works for me evileye might just be "Snake oil" for you!

Thanks for the advice, I will try that, I have yet to try the 69 grain bullets but I have the 1 in 8 twist which should handle the heavier bullet with no problem.

Buzzard Bait,
Which factory 69 grain bullet would you recomend or do you roll your own? I have the 50 grain and 60 grain v-max in black hills but have not tried the 50 grainer yet. My AR is Also a RRA 20" 223 Varminter(1-8 twist).Thanks for more input!smokesmile

If you have a Mil-Dot scope you can zero it at 100 yds on the first dot above the crosshair that way if you have a close "peeker" you know exactly where your POI is.

I have loaded the Sierra Match King, Boat-Tail Hollow Point as well as the Nosler, and both work well and BOTH require minor tweaking to zero, so they are NOT to be mixed as fodder.

It's 25 grains of Varget and Fed Mag primers. REMEMBER to fully prep your case before loading and remember once fired cases from an AR do not reload well as the heated case and the twisting from the extractor motion tend to stretch or buldge the case and it in my opinion is not worth the hassle to babysit to reload and due to the lack of chambering & reliability in the field. I have had a few case seperations and stuck cases to base my extreeme prejudices of once or more fired brass reloaded for an AR. ...
