zeroing a red dot on a rifle

[Sasko31]

Ok purchased a vortex strike fire. Mounted on a xcr l never owned or used a red dot what is the recommended method and range to zero it.

Start close range(25yd) with big paper or sand bank to spot hits. Read the specs to find out how much each click is and go from there.

On a rifle like yours, I tend to separate the upper, ditch the bcg at home, and bore sight the windage first. Then use a large target as mentioned above.

Point of aim point of impact? At 25 do you have it below point of aim. Is there a link to a thread about co witness iron sight to scope. Tried advice off you tube video do believe it was incorrect.
Had it zeroed at a hundred. But not working for close 5 shots for 1 beaver. Dot on beaver at 30 m rounds consistently hitting water in front of beaver. Yet at 100 m rounds punch steel plate 8 by 10 inch center of mass.
Able to punch steel at 450 m with set up yet can't hit a beaver at 30 m.
Having to eat humble pie.......
open to suggestions or links to credible YouTube videos.

No manual.... trying to short cut the Internet search time and tap into people's actual experience.

Oh well guess the wise shooters of the Internet are too busy.
so after searching through gunnutz and 2 other sites. 50 yard zero for a vortex strike fire will put the rounds were i need them to be.
And the awsome instruction manual downloaded from vortex site pretty much just says to zero at 25 and a 100.

Use sand bags or a bench rest to ensure good and secure, aim at the bulls eye or an "X" drawn on a cardboard.

Repeat but while aiming at the "X" adjust sight to move dot to point of impact (POI).
