Leupold's Target Cross hair is .00013 as where the ones Premier would install, this is taken from one of the Premier Catalogs I have kicking around, if anyone would like this in PDF form email me and I will get you a copy.

By far our most popular reticle. It is a very pleasing
reticle to the eye because of it's simplicity.
The round dot naturally draws the eye to the center.
Two style dot reticles are available. First is the
target dot reticle installed on target style
crosshairs. Often referred to as a floating dot reticle.
The supporting lines are so fine that under
certain conditions they have the appearance of
disappearing.
The second style dot reticle, having medium to larger size dots, would be
installed on fine appearing crosshairs that measure .00045"
Line sizes available with dots
To give you an idea of the actual size of the target crosshairs they are 3.3
microns. 1 micron is 1 millionth of a meter or .00004". Another comparison
would be this line is about 20 times smaller than a human hair.
There are certain limitations to consider whether or not a target dot would
be practical in your scope.
First, very small dot sizes must be installed on the target lines and would
include dots .0024” and smaller. As an example 1/2 moa in 6X, 1/4 moa in
12X, 3/16 moa in 20X or 1/8 moa in 24X or 36X scopes. All these dots
measure .0024" or smaller. See the reticle chart showing dot sizes and line
sizes available in the various Leupold scopes.
Second, if a very large dot size is ordered it may be too massive for the
target lines to support and could break at recoil. We would use the .00045"
lines with the larger dots. Lines sizes over .00045" are not available with
No. 3 dot reticles.
Target dots are available in standard or custom sizes when installed in a
variable power boost.
Selecting a dot size
Three factors determine what the best dot size would be.
First the dot must be the appropriate size for the target. You don't want a
dot so big it covers the animal or aiming point on the target. Remember,
as the distance to target increases so does the coverage of the dot on the
target. As an example if a 1/2 minute dot was installed in your 12X scope
and you were shooting at prairie dogs at 600 yards the dot will cover 3
inches (.5 X 6 = 3). The average prairie dog is only 1-1/2 inches wide. As
you can see a smaller 1/4 moa dot would be more appropriate.
The second factor used to determine proper dot size is the magnification of
the scope. Unfortunately this is one of the most difficult concepts for most
dot users to understand. Simply put, the higher the magnification of the
scope the smaller the subtension of the dot that can be installed. So often
dots too small for the magnification are requested. For example a 1/8 moa
dot would be ordered to be installed in a low magnification scope. If made
it would be impossible to see even for the best of eyes.
This 1/8 minute dot is a standard dot size for both the 24X and 36X
scopes. To give you an idea of comparative size: if a 1/8 minute dot that
measures .0024" were installed in a 6X scope it would subtend 6 times
more on the target because the power of the scope is 1/6th the power of a
36X scope. This .0024" dot would therefore cover 6/8th or 3/4 minute if it
was installed in a 6X scope. Imagine, if you can, a dot that would appear
6 times smaller than a target dot in a 36X scope! Impossible to see and
not a very good choice.
The third factor for proper selection of a dot after the first two are considered
is "How good are your eyes?" Generally speaking younger eyes
can see smaller dots.
It is impossible know what size dot you will be able to see when the smaller
sizes are requested. We use our best judgement based on the three
above factors when determining an appropriate size. See the reticle subtension
chart for our smallest and largest recommended dot sizes for various
scopes.
Reticle No. 6
Our reticle number 6 is a plain and simple
crosshair reticle. The name crosshair is mistakenly
used by many to refer to any style reticle. A
duplex is not a crosshair nor is any other style.
We offer three crosshair sizes in all standard
Leupold scopes (except LPS).
First is the .00013" target crosshair. As explained
under the number 3 reticle, this is the smallest
size crosshair that may be installed. It is referred to as a target crosshair
because it is customarily installed in high magnification scopes. It subtends
the least amount of any reticle we offer. It can be installed in any Leupold
scope but should be chosen with caution if it is to be used under low light
conditions, dark backgrounds or if your vision is not good.
Second choice is a .00045" fine crosshair. It is more than 3 times bigger
than the target crosshair and is more suitable for varmint hunting and for
less than perfect eyes. Many benchrest shooters prefer the fine cross hair
over the target crosshair because it does not cause eye strain.
This .00045" size is mostly used with multiple dot systems with average
size dots.
Third choice is the .0010" medium crosshair. A much more visible reticle
than either the target or fine crosshair it is the same size as used with mildot
reticles. Medium crosshairs CANNOT have multiple dots added or be
used with single dot reticles.
These three sizes are considered standard sizes. Multiple dot reticles are
installed ONLY on .00013 or .00045 crosshairs and are not available with
other size lines.
. So .0005 would be .5 @ 100yds.
