So I appreciate your input....as with the others who have actually used them.

My question is this:

So idea goes that you need consistent head position/cheek weld etc or else you will introduce parallax issues.....parallax leads to opened groups or wandering zero--(for lack of better terms).....

But if the parallax is so small (so affect on groups).. then why worry about it?

So then, of course, within reason, why worry about forcing your head/eye into a particular spot? (So no need for the reducer).......?

In other words if the affect on groups by the question of parallax is so small, why worry about going thru all these steps to correct or eliminate it?
Parallax isnít the issue unless you have your eye alignment so off that the image is heavily shadowed and you are shooting very Close or very far. I once did a spreadsheet to calculate parallax and with a 24 mm objective and parallax set @ 300 yards maximum possible parallax error at 200 and 600 was only like 0.1 moa.

Varying head pressure and position creates varying loading on the rifle butt that causes shots to go where they were not aimed when you pull the trigger. With a huge field of view in a scope it is easy to get sloppy whereas with a .042 aperture it forces you to place your head consistently
