Have you recently purchased a new scope? Then you should verify the actual click value of the turrets before you use the optic in competition (or on a long-range hunt). While a scope may have listed click values of 1/4-MOA, 1/8-MOA or 0.1 Mils, the reality may be slightly different. Many scopes have actual click values that are slightly higher or lower than the value claimed by the manufacturer. The small variance adds up when you click through a wide range of elevation.

In this video, Bryan Litz of Applied Ballistics shows how to verify your true click values using a “Tall Target Test”. The idea is to start at the bottom end of a vertical line, and then click up 30 MOA or so. Multiply the number of clicked MOA by 1.047 to get the claimed value in inches. For example, at 100 yards, 30 MOA is exactly 31.41 inches. Then measure the difference in your actual point of impact. If, for example, your point of impact is 33 inches, then you are getting more than the stated MOA with each click (assuming the target is positioned at exactly 100 yards).

How to Perform the Tall Target Test
The objective of the tall target test is to insure that your scope is giving you the proper amount of adjustment. For example, when you dial 30 MOA, are you really getting 30 MOA, or are you getting 28.5 or 31.2 MOA? The only way to be sure is to verify, don’t take it for granted! Knowing your scopes true click values insures that you can accurately apply a ballistic solution. In fact, many perceived inaccuracies of long range ballistics solutions are actually caused by the scopes not applying the intended adjustment. In order to verify your scope’s true movement and calculate a correction factor, follow the steps in the Tall Target Worksheet. This worksheet takes you thru the ‘calibration process’ including measuring true range to target and actual POI shift for a given scope adjustment. The goal is to calculate a correction factor that you can apply to a ballistic solution which accounts for the tracking error of your scope. For example, if you find your scope moves 7% more than it should, then you have to apply 7% less than the ballistic solution calls for to hit your target.

NOTE: When doing this test, don’t go for the maximum possible elevation. You don’t want to max out the elevation knob, running it to the top stop. Bryan Litz explains: “It’s good to avoid the extremes of adjustment when doing the tall target test.I don’t know how much different the clicks would be at the edges, but they’re not the same.”

Should You Perform a WIDE Target Test Too?
What about testing your windage clicks the same way, with a WIDE target test? Bryan Litz says that’s not really necessary: “The wide target test isn’t as important for a couple reasons. First, you typically don’t dial nearly as much wind as you do elevation. Second, your dialed windage is a guess to begin with; a moving average that’s different for every shot. Whereas you stand to gain a lot by nailing vertical down to the click, the same is not true of windage. If there’s a 5% error in your scope’s windage tracking, you’d never know it.”

Verifying Scope Level With Tall Target Test
Bryan says: “While setting up your Tall Target Test, you should also verify that your scope level is mounted and aligned properly. This is critical to insuring that you’ll have a long range horizontal zero when you dial on a bunch of elevation for long range shots. This is a requirement for all kinds of long range shooting. Without a properly-mounted scope level (verified on a Tall Target), you really can’t guarantee your horizontal zero at long range.”

NOTE: For ‘known-distance’ competition, this is the only mandatory part of the tall target test, since slight variations in elevation click-values are not that important once you’re centered “on target” at a known distance.

Schmidt & Bender 5-25×56mm PM II SFP Review
Test conducted by RifleShooter.com
For police and military use, the Schmidt & Bender PM II (Police Marksman) is the gold standard of extreme use rifle optics. Other high end scopes aspire to the PM II’s level of durability, optical clarity, repeatability, and performance. With our assistance, RifleShooter.com recently conducted an in-depth test of Schmidt & Bender’s 5-25×56 PM II, Second Focal Plane (SFP) version. Here are the results…

» READ FULL 5-25x56mm PM II Scope Review (LONGER VERSION)

The test scope is a 5-25×56 PM II (SKU: 677-911-995-A8-A2) with a Second Focal Plane (SFP) P4FL2-MOA reticle; double-turn elevation with rotation indicator; single turn windage; 1/4-MOA click values; illuminated reticle; and side adjustable parallax from 10 meters to infinity. This is an impressive beast — a big, sturdy, well-made optic.

Schmidt & Bender scopes have sophisticated features and a wide array of available options. The many options and features of the 5-26x56mm PM II are explained in this Schmidt & Bender video:

Second Focal Plane (SFP) Reticles
The Second Focal Plane (SFP) reticle design works well for long-range target shooters, benchrest shooters, hunters, and law enforcement. Often, SFP reticles are associated with Minute of Angle/MOA-based reticles. For target shooters who like to dial-in the elevation corrections, frequently SFP is the preferred reticle type. Also, these reticles are offered with thinner lines and markings to aid in target shooting, by not covering up as much of the target area, which is absolutely necessary in such cases as F-Class and Benchrest shooting. With a SFP reticle the size/width of the reticle lines stay constant at all magnifications.

Tall Target and Box Tests

Commentary by Rifleshooter.com Editor
To get an idea of how the PM II tracked I wanted to conduct a tall target and box test. I set up a couple of ISPC targets at 100 yards (below).

The target on the left is for the tall ladder test, the target at the right is for the box test.

With the scope zeroed* I set up a tall target test at 100 yards. I placed a 1″ orange dot on a pair of targets (above, left). We then used a four foot level to draw a plum line moving up from the dot and fired the three shot group below.

I dialed 30 MOA of elevation on the scope and fired another group. Measuring the distance between the two groups, would indicate how well the scope is tracking.

Since 1 MOA is 1.047″ at 100 yards, 30 MOA would be 31.41″ (30 x 1.047″ = 31.41″), looking at my tape measure, everything checked out (above).

Next I conducted a quick box test and set up an IPSC target with a orange paster at 100 yards. To do this I first Fired one round with the scope zeroed, then…

Dialed 6 MOA left, fired one round
Dialed 15 MOA up, fired one round
Dialed 6 MOA right, fired one round
Dialed 6 MOA right, fired one round
Dialed 15 MOA down, fired one round
Dialed 6 MOA left and fired one round

After this, you want to see two holes close to each other on the first target, as well as the correct spacing dialed in between each hole, so how did the PM II do?

Well, it worked like a champ! The rest of my time with the PM II has been equally impressive.

SUMMARY — Our Assessment of the 5-25×56 PM II

Here are our key conclusions from testing the Schmidt & Bender PM II 5-25×56 SFP:

— Crystal clear glass. Great light transmission and reticle.

Turrets and Controls — How They Work

On the right side of the optic, you’ll notice a .250 MOA single-turn windage adjustment knob. On the top you’ll note the .250 MOA elevation adjustments. The tactile feel of each “click” is impressive — crisp and precise. A large parallax knob is located on the left side of the turret. The smaller knob located closer to the eyepiece is the adjustment knob for the illuminated reticle.

Here the view from behind the scope. Note the DT (double turn) elevation turret. At its current setting in the photo above, it is still on the first revolution (.250 MOA below 0) and as adjustments within the first revolution are made, you’d read the white numbers. During the second revolution, the windows in the top of the turret turn yellow, as shown below.

Test Rifle — .300 Win Mag in Accuracy International AICS AX Chassis
For testing and evaluation purposes I mounted the PM II in Spuhr ISMS mount on a custom made .300 Winchester Magnum rifle. Testing was done with handloaded ammo: Sierra’s 195-grain Tipped MatchKings over Norma brass and Hodgdon H4831SC powder.

This is the test rifle I used. It was built primarily with parts from Brownells.

Here is the Schmidt & Bender 5-25x56mm PM II SFP (foreground) alongside three other S&B products:
5-25×56 PM II FFP (Desert Tan), 12-50×56 PM II, 3-20×50 PM II

Better Pricing, Better Warranty, Better Availabilty
In addition to increased production and availability, Schmidt and Bender has reduced retail pricing on PMII models 14-19% depending on the model. S&B Marketing Director Kyle Brown commented, “S&B improved its warranty in the USA for 2017, and now offers a USA 20-Year Transferable Limited Warranty. We have reduced our pricing to be competitive; and have greatly increased our on-hand inventory levels to supply our customers with complete and on-time deliveries.”

Schmidt & Bender has made an effort to support the Precision Rifle Series (PRS). Brown said “for 2017 we have made a very hard push to become more active in PRS with our brand and with our products.”.

Need a high-magnification scope for long-range competition? Among quality scopes with 40+ power, we think the Sightron SIII 10-50x60mm scope may be the best value on the market right now. For a limited time, these scopes are available through Amazon.com for under $980.00. That’s less than half the price of a Leupold 7-42x56mm VX-6, and about 42% of the cost of a Nightforce 15-55X competition model. The Sightron is a good product with a lifetime manufacturer’s warranty.

MOA-2 Reticle

Target Dot Reticle

Fine X-Hair Reticle

Mil-Dot Reticle

NOTE: There are a variety of reticle options and both 1/4-MOA and 1/8-MOA click versions are offered. Read the product description carefully when ordering to be sure you’ve selected your preferred reticle type and click value.

Less than Half the Cost of New 34mm 10-50x60mm Sightron
Sightron’s SIII series 10-50x60mm riflescopes have a 30mm maintube. NOTE: Sightron has announced a new “SV” model 10-50x60mm scope with a 34mm maintube. The new “SV” 10-50 scope is nice, but it costs $1999.99! That’s more than DOUBLE the cost of the 30mm-tube 10-50X SIIIs featured here. Think about it — the older 30mm SIII 10-50X offers way more bang for the buck.

Proceeds from Scope Sales Help Our Shooters’s Forum
When you purchase one of these Sightrons from Amazon, you can improve your long-range capabilities while helping our Shooters’ Forum. For every scope sold, Amazon provides roughly $50.00 to this site. All scope sale commissions will go to provide IT and tech support for our Shooters’ Forum. You don’t pay a penny extra — you pay the same price as any other Amazon customer. But because the sale originated here, Amazon pays a commission. So you can get a great deal, while helping the Forum at the same time.

Editor’s Comments: Here’s our take on this scope. For long-range benchrest and F-Class, it is one of the best options if you can’t swing $2000-$2500 for a Leupold, March, or Nightforce. We’ve used the 10-50X SIII Sightron in competition, and it’s plenty good enough to win matches. The glass is sharp and the clicks are reliable. Anything better (in this class) is going to cost you a LOT more.
