Plugging my info into a ballistic calculator puts me at 36 MOA, which is why I said "about". 26" Barrel, 175 gr SMK, .496 BC, 2665 fps, 800 ft elevation and 85 degrees.
Yes, it does depend on barrel length, muzzle velocity, BC, and other factors. What I was getting at was that 44" is not the holdover.
I now see that that is not what MTSCMike meant by it, but that is what it came across as. Since the OP asked what his holdover should be, I didn't want him to go out and hold 4ft over his target at 1,000 yards with a 100 yd zero and expect to be close...
