ir, Your not the first person to explain this challenge and I really appreciate the info. As a very young man, In basic training, with a strait away tail wind well over 20mph (Ft. Sill, Ok) I was incredibly lucky to hit a pop up at 700yrds with an M-16 A3 Shooting off a sand bag. Using 55g. Army issue 5.56 @3270fps (according to what they made us memorize...always doubted the speed but you can't argue with a drill Sergeant...) I have been hooked on the AR rifle ever since. As I have gotten older, and became somewhat knowledgeable of the limitations of that round and rifle, I realize I was indeed, lucky to hit that shot...(actually did it 3 times, twice while the senior drill was watching). The scope within my budget is the zhd520r-Zulus HD 5-20x....got it for $580.00 (new)...The cold hammer forged 20' barrel is from Palmetto State Arms...on sale $480.00 (1-7) twist. Lower is a CMMG with a Rock River Trigger $346.00. Next purchase will be a good precision platform to shoot from. Got about $600.00 to spend on this. Will rely on my phone app. for weather conditions at the time. I see your data on the 88g ARC. I considered this round but choose the 62 grain (see attached BC chart)...it's currently without wind drift but I am working on that problem. I understand the sales pitch Hornady's sending my way and will consider other rounds if unsuccessful. Always liked a challenge and just starting to enjoy my retirement. I am looking forward to what I might learn from this project and other shooters like you. PLEASE feel free to pass on any knowledge or advice....It would be welcomed. With respect...Jeff S.Just for fun:

Good Luck with this.
The only folks claiming 'game changer' status are the advertising writers for Hornady (who have done a great job in the past deluding us). The wannnabe influencers also join in the fray just so they can say they know more than we do...
At 1,000 yards your drop will be 315 inches or 26-1/4' (feet), drift is 6.2' (feet). Your scope choice, not including add-ons, should have this much available correction or add more money for a better range of adjustments.
Personally, I'd look at another cartridge and get some better ballistic information to use when making these decisions. Sorry to make this judgment but $2,000 is simply not enough to create the rifle +scope you want, to achieve what you're asking.
Now, on the other hand, it's your money and you are certainly able to spend it as you see fit.
Enjoy the search!
B,,Hornady sent me the table......big difference is they are using a 24' barrel and shoot in an underground tunnel (no wind) at 200yrds in order to get their 3400fps speed. Switching to the 88g on your suggestion. Big thanks... P.S...How is that 75g performing past 400 yrds in your 18' barrel and can you go further accurately? With respect...Jeff S.You are correct, it would be more like 29 MOA and closer to 300 inches of drop.
18" barrel with 1-7" twist
In my rifle I'm getting right at 3150fps with the 62gr ELD-VT and a little over 2800 with the 88gr ELD-M. The BC on the 88gr is considerably higher than the 62's and will stay supersonic somewhere around 200 yards further. Plus, the wind deflection is better with the 88 starting relatively quick. According to the numbers, the 88 should make for a better 1000-yard projectile.
The 75's shoot the best in my rifle so I'm currently using them.
