I have a .22 rifle and I am trying to adjust the scope.

Unfortunately, I am limited to 12 feet distance at the moment.

I just made a great .22 target/catcher from a 12x12" 1/4" steel plate
and wood, so I can now work on the scope.

At exactly 12 feet of distance, impacts very reliably end exactly 1
inch to the left.

The scope is this:

An adjustment of 1/4" MOA means 1/4 inch per click at 100 yards. 12
feet is 4 yards, so one click means 1/4*4/100 = 0.01 inch. So, to
adjust the point of impact by this much, I would need to adjust the
scope by 100 clicks?

This does not make sense to me. Would it suggest to you that something
is seriously wrong with the scope, or the way I mounted it?

At that short a distance, the offset between barrel and optical axis
is going to give you problems.

You mean, on the vertical plane, right? I simply adjust for this and
aim about 1.5 inches higher than the tagret.

Also, .22 scopes are usually set for parallax for 50-75 yards, just
moving your head a bit at that short a distance will make hash of
any adjustments you're trying to make. What you need for initial
setup is a laser boresighter, I usually use the license plate on my
trailer for a laser target at night for initial adjustments. Good
enough to get on the paper when I get to the range. 21' is just too
short for boresighting.

That's an interesting idea, but how accurate are those boresighters?
