zoom scopes

[hodgy]

is it true that the zero moves when you use the zoom on "cheaper" scopes such as simmons or tasco, as apossed to expensive ones like zeis which dont??` <img src="http://jsramsbottom.co.uk/bbs/e/icon_confused.gif" alt="Confused" width="15" height="22"><!--graemlin::confused:-->

zero shouldn't change period
if it does the scopes u/s

Fair point Gary, but the tendecy for it to occur is definately greater with cheap stuff

It can do.

But the most important thing to note is that unless your scope reticle is in the first focal plane, then all of your holdovers will be different (in relation to the primary zero) when you use the zoom.

On a second FP scope (even top-line Leupolds) the only time the POI will remain constant is when you are using your primary zero. That shouldn't change at ANY magnification.

If you can't afford a decent scope then just use the same mag all the time.

I have a couple of parallax adjustable Hawke scopes, and I must say that I have never found it a useful "feature". If I use the PA to help me focus the image to my imperfect eyesight the zero shifts, and if I reset the PA to it's previous value the zero does not alway return!. As a result the PA rings on my scopes are now locked with insulating tape. Am I missing out on anything useful as a result?
