Gold dots are not made for flight, so that 2 mils sounds about right from a shorty. The flattest shooting load known to man (in 5.56) is the 69gr TMK in 5.56 from Black Hills if that interests you.

Ok, barrel and optic are GTG. Your dope sounds about right for the speed of that bullet from a shorty, velocity is probably ~2450. Your shooting is GTG.
Now it's just a matter of picking a load for you.
Yeah, that 5.56 69 SMK and TMK has some magic in it.
Thats a good setup. My 11.5 is a cl barrel with a 1-4.
I also just checked, I was shooting fed fusion, I'll have to try the 69 handloads at 600. I believe they are between 223 and 556 pressures as Im getting 2800 fps from a 16"
Ill chrono and see how far I can push them from the 11.5"
Update: I only had access to 300 yesterday.
1.2 mil at 300yds. 69gr@2600 from my 11.5" w/socom556mini.
I have found the 75 Gold Dot to be an excellent bullet. The BC isn't as good as a 77 TMK/SMK/NCC, although Speer shows it as .400, but they shoot sub MOA from my 16" AR and Tikka.
Sorry ahead of time for the thread drift...
How good ? I realize it isn't match ammo, but I usually got 5-6MOA, while other brands were easily 2.5-3MOA.
Do you remember which specific one ?
I have always had dismal results from Winchester bulk 5.56 62gr and 55gr ... has that changed ?
I have always wanted Winc. bulk'ish to shoot decent, but it just never has for me over the decades.
That one, but no difference between the 20/150/200 packs. Recent data: 10rd/100yds, GTG Geissele barrel, 9rds ~2" with the tenth an obvious called flier. Runs about 3050fps with SDs in the teens. This is recent production out of LC. I've shot this in GI and precision barrels, it flies atypically well.
