Maximum distance you can reliably first-shot impact 1MOA, 1/2MOA target?

MOA is not unreasonable
Personally, I’ve had my best rifle impact miss .1 off the 1in zero target. Sun? Trigger finger? Zero shift? Lot change? I dunno.

I read this as what could I guarantee, I think hitting a 1moa target even at 100, over a long enough period of time, some variable would align and I personally would miss.

Personally 3moa, no problem.

Just my 2c.

What means "over a long enough period of time" to you?
9/10 cold bore shots on different locations?
99/100?
999/1000 maybe?
Specify
Personally 3moa, I consider a problem for 1000/1000.
Bad load, you sneeze while pulling the trigger and so on
 
fwiw, i'm on day 21 of my experiment. AXSR 300nm @ 410+ yards, 1 shot per day across a holler one ridgetop to another, different times, positions etc. only 2 days rain. None of the misses were from prone or when raining.

17 hits, 4 misses - 81% hit rate
11 of the hits are inside IPSC A zone (1 7/8" tall by 3 7/8" wide box in upper half of the 6"x6" head).
IOW 11 of 21 shots are in a .5 x 1 MOA rectangle. The remaining 6 hits are in 1.5 MOA square.

1 miss was just low and due to ammo (at least, i assume as the garmin read the fps about 5 STD below mean.)
1 miss was just left missed wind call.
2 miss were just high, i attributed one to light and the other to wind moving up the face of the mountain toward the target, but just a guess

I will say, I think i'd have more hits shooting my 6dasher or 6.5x47. 300nm seems a lot less forgiving.
Nice grouping, gunney.
