That seams to sum it up I guess.
It has never been a concern to me maybe it should be.
The way I take it is If your NOT EXACTLY square to both leases the crass heirs will move across the target if the Parallax is not set right?
I guess I never noticed. I have shot many animals at well over 300 yards, must have a lota luck, or set the scope/rifle exactly right?
The new Burris has a parallax adjustment ring on the front of the scope.
I'm thinking for hunting purposes I'll just leave it at around 200 yards.
I don't plan on hunting coyotes with it so tight quartets should not happen fast and need to be thinking about such stuff.
BUT if I need to go out to 400/500 yards with the 8 I now can and try it out.
Thoughts anyone?
Clear as mud right?

Ok, difficult to express.  BUT, your scope has an adjustment on the front (objective lens), and one on the rear (ocular lens).  Assume a SFP scope

The rear lens adjusts the parrallax ONLY.  this it to keep the crosshairs in the center plane of the internal erector lens.  It is adjusted ONCE and then never touched.  Adjust by holding the scope up to a nice white sky.  Look quick, then adjust a little, then look away to avoid your eye correcting.  keep doing this till you see just one cross-hair, sharp without a second hair close by.  done.  set locking ring and forget.

The front lens is a focus, just like binoculars.  Change it to see objects at various ranges.  I set it at the range I expect to see game.  when getting a shot (usually sitting for me) I change the focus to bring the image in clearest.  scpes without this adjustment are set a 150 yards, a good compromise as the further away the less critical it is.   for what it is worth you can use this feature backwards--look at a target and adjust the front lens till you get it clear, red  the front lens yardage for the range.


just Sunday thoughts  (rifle buck season was over last evening)

Parallax?!? Wasn't that the bad guy from Green Lantern?

If your eyes are finely equipped and you play enough at the range. Use of it for rangefinding is possible as well. It gets you pretty close. The old 6x24 I had on my 22-250 and younger eyes made for a deadly combo on groundhogs out to 500. Eyes failing as well as other parts keep me much closer in range these days to the point where that doesn't matter.
...oh yeah! thats gonna hurt!
