How much parallax is acceptable?

[Topshot]

I have two Burris scopes and they both seem to have a heap of parrallax.

If I move my eye up and down or back and forth, the cross hairs move about one and a half minutes of angle on a target at 300 yards away.

These scopes do not have an adjustable objective lens. How does this amount of parrallax compare with other scopes that have no parrallax adjustment?

Short answer is ZERO!

Most fixed objective scopes are set to have zero parallax at something like 150 yds.

However, with the Leuy VX-IIs that I've had parallax has not been a problem.

A workaround is to back off the scope enough so that you have a black ring, small or large, around the reticle center. This is not the best for hunting except for chucks and such and targets, but it helps w/the parallax problelm.
