Re: Parallax Adjustment.
<div class="ubbcode-block"><div class="ubbcode-header">Originally Posted By: RotARy15</div><div class="ubbcode-body">Help inform this newbie on parallax adjustment. Specifically, why do a lot of optics skip certain ranges in adjustment?
I have noticed optics that list parallax settings in an order such as, 75-100-150-200-300-500-600-700-infinity.
It skips the 400 yard setting and the progression has no uniformity. Is there a reason for this? I understand basic parallax but am not an expert. Am I missing something?
Thanks in advance,</div></div>
1. they can't fit (label) all the numbers in the small space
2. they figure if you can split the difference between 300 and 500, you must be around 400.
3. it's not set in stone, for your eye (and especially on cheaper scopes) you may find it's clearest B-4 or after the labeled distance you intend on shooting at. also on the cheaper scopes, you may see it will vary with the power of magnification you are on.
4. you'll also find the lesser distances more commonly labeled as that's the range where most of the shooting public will be shooting.
5. as you go up in labeled distance, you'll see the space between the labeled distances gets less as a smaller adjustment makes more of a difference, just like adjusting an elevation or windage turret.
many of the reasons why you shouldn't use the parallax adjustment as a ranging tool, as some say is OK to do. a very rough yardage, maybe, but not something that should be relied on for ranging.
