Delta Optical Stryker 5-50x56mm HD Scope Field Test

delta optical stryker 5-50x56mm long range SFP MOA scope test review james mock

Product Review By James Mock
There is an old adage when it comes to buying rifle scopes — one should “buy the best and cry once”. Generally it is true that we get what we pay for. However, we all like to get full value for our hard-earned dollars and it seems that we have several top-flight rifle scopes available to shooters today. Many of these top-tier scopes carry a premium price of $3000 or more. If one has champagne tastes and beer budget, must he/she settle for a second-tier scope?

The answer to the above is “not any more”. Check out the new Delta Stryker 5-50x56mm at under $1600.00 retail. A well known gunsmith told me that if someone made a scope with the quality of glass found in a Nightforce Competition and the reliable tracking plus ability to hold point of aim of the Kahles, they would have a winner. I have shot both of the above-mentioned scopes and they are great scopes. If one could get the best traits of both of these in one package and could get that optic at a good price (relative term), it would be great.

I may have found such a scope with the Delta Stryker 5-50x56mm long range scope, currently $1590.00 at SW Optics. Since I shoot mostly 600-yard matches, I requested the 5X-50X Stryker model with second focal plane (SFP) MOA reticle and 1/8-MOA adjustments. Here are the key features and specifications:

Gen 3 Delta Stryker Long Range Optic
Note: Shown above is Delta Stryker’s new Generation 3 offering. This incorporates features wanted by purchasers of earlier generation scopes. Delta has made some great improvements to this scope. Key Gen 3 upgrades are: 1) Indicator added to show the number of revolutions the turrets have been turned; 2) Locking turrets for both windage and elevation knobs; 3) Unique Zero Stop made of brass rather than plastic; 4) MILRAD models now have .05 mils per adjustment clicks; and 5) Parallax adjustment wheel was given much longer travel which benefits getting the fine adjustments needed.

Other features of this second focal plane (SFP) scope include Japanese ED glass, illuminated 1/10 MOA dot with 11 brightness settings, zero lock turrets, 1/8 MOA click values, and a 10 year warranty. There are three reticles offered in this 5X-50X model. The DLS-1 and DLS-2 reticles are MILRAD types, while the third DLS-3 reticle, the one I tested, is a MOA reticle with each hash mark subtending 1 MOA at 40 power.

Turrets Run Smoothly with Easy to Read Markings
The markings on the turrets are large and easy to read with 10 MOA per revolution. The center dot subtends 1/10th MOA. The illumination on this model illuminates only the dot. The Gen 3 comes with sunshade, hex wrench for adjustments of zero stop, scope caps, a tab for the power ring, an optional large parallax wheel, and glass lens cover. It has a 10-year warranty. When one turns the windage, elevation, parallax, or power change knobs, he or she realizes what a quality scope this is. All of the above adjustments could not be smoother if they were on ball bearings.

The objective lens is 56mm. The image produced by the ED glass in this scope is spectacular — equal to or better than many scopes costing twice as much. There is little of the dreaded “black ring” surrounding the image. The adjustments are very, very smooth and the clicks are positive and without the backlash evident in many scopes. This is very well thought-out scope and represents one of the great values available today.

DEVA Institute Tests Confirm High Light Transmission
Delta enlisted the services of the prestigious DEVA Institute in Germany for an independent evaluation. The Deva Institute gave the scope a thorough “going over”, determining that that the individual lens layer allowed 98% light transmission while the total system allowed 92%. The scope is also very tough and withstood 6500 Joules (~5054 ft-lbs) of recoil energy.

Field Test Results of Delta Stryker 5-50x56mm

My testing began on a cold January 29th, 2022. I designed a tall target with a vertical line drawn with a level and marked that line up 25 MOA in 5 MOA hash marks. I set up my rifle (Stiller Cobra) on the bench and leveled both the rifle and the scope’s crosshairs. The model that I am shooting has 1 MOA hash marks with a 1/10th MOA floating dot. This reticle is ideal for 600 and 1000 yard competition. The rifle is currently chambered in 6mm PPC and I tested with N133 and Bart’s Avenger BT bullets. I will change the barrel to a 6mm Dasher before the next 600-yard match.

Photo below shows the setup with tall target at a measured 100 yards. I measured 100 yards with a steel tape to make certain that I did not skew my results but shooting at a greater or less distance. I will do some more testing at this distance when the weather warms a bit.

Tall Target Test — 25 MOA Up and Back Down
For this test I created a target with two sighting points placed a measured 25 MOA apart. I shot a few rounds of old ammo to get a rough zero and then fired an initial sighter. After an adjustment, I fired the first test shot and it hit in the proper location (inside the lower circle). Then I adjusted the elevation up 25 MOA. I fired again and the bullet impact was VERY close to my measured +25 MOA hash mark. Then I cranked 25 MOA back down and fired. That drilled the third test shot in the original circle at virtually the exact original elevation. This confirmed the accuracy of the click values.

Below is a picture showing the impact with the 25 minutes dialed in the scope. Although it is not perfect, it is VERY good. This scope tracks very well. The picture below shows the great tracking at 25 minutes up.

The final test done today was one in which I tested for shift in point of aim with power change. The first two rounds were fired at 40X, then I moved followed by one at 30X, another at 25X, then the final two rounds at 15X.

For each of the test magnification levels I had an aiming box on a vertical line. I started with 40X, then moved my point-of-aim down to the next box in sequence as I reduced the magnification level: 30X, 25X, and finally 15X. As you can see, the impact was very good at all the tested magnification levels.

Excellent Quality Image
Viewed through the Lenses

Delta Optical is located in Poland. The company’s devotion to excellence is very evident. The brightness and clarity of the Delta lenses is amazing and the scope has large internal lenses as demonstrated by the sight picture. The tunnel effect with the black ring surrounding the image is absent in this fine scope.

Let me add that on two occasions, I have tested with extreme mirage and this scope handles the mirage as well as any I have tested. After all of my shooting, I can say that this scope has passed the tests with flying colors.

SUMMARY — Excellent High-Magnification Optic and Great Value

I have previously named other scopes as being the best value in long range scopes, but I may have to reconsider that statement. For a scope as versatile as the Delta Stryker 5-50x56mm, the price is very reasonable ($1590.00 at SW Optics). There are scopes that cost $1000 more without the features of this offering. My testing will continue and there will be updates. I want to thank Mr. Grzegorz Matosek of Delta Optical. He made it possible for me to have this scope for testing.

My shooting partner, Kent Bennett, remarked recently when we were testing several guns at his range, that this scope is as clear as any [high-magnification optic] he has looked through.

I predict that this Delta 5-50x56mm scope will sell very well in the USA. When the word gets out about the features and overall quality of this instrument, I believe that long range shooters will want to try it. There are two USA importers with which I am familiar: SW Optics & Equipment (Arizona) and EDgun West (California). My prediction is that those who try this scope will not be disappointed with quality or price. — GOOD SHOOTING! — James Mock

Berger 6.5 Creedmoor Ammo Performs Great in PRS Rifle

Erik Cortina Berger Factory ammo ammunition OTM tactical PRS rifle MPA chassis Lapua brass

Is factory 6.5 Creedmoor ammunition good enough to win a PRS or NRL competition? The answer is a resounding “YES” if we’re talking about Berger ammunition. Produced with Berger match bullets and premium Lapua brass, this Berger 6.5 ammunition demonstrated excellent accuracy, impressive velocity, and very good ES/SD numbers. When tested at 1000 yards with an MPA-stocked PRS rig with Rem 700 action, this ammo showed just half-MOA of vertical, and produced a group that would have been a 50-1X in F-Class competition. That’s quite impressive for a PRS rig.

This ammo test was performed by our friend Erik Cortina from Texas. Erik is a top F-Class competitor who also shoots tactical matches (for fun and glory). Erik recently built a new 6.5 Creedmoor with a Remington 700 action. Though this rifle sports a top-shelf MPA chassis and premium Kahles scope, Erik calls this his “budget build” because it has a plain Rem 700 factory action rather than the elite Borden actions he normally runs. Erik’s actions of choice are the Borden Mountaineer for PRS and Borden BRM-XD for F-Class.

Erik posted: “Shot my budget 6.5 Creedmoor today with Berger Bullets factory ammo. I shot five rounds over the chrono to get speed. I used BC info from the box and it all lined up properly. I adjusted my ECTuner to tune load and it took just 15 shots to get it shooting well. It’s simple with good components.”

This Berger factory ammo features Berger 130gr Hybrid OTM Tactical bullets. The Lapua 6.5 Creedmoor cases have a large rifle primer. You can see this ammo displays good velocity with Extreme Spread and Standard Deviation rivaling good hand-loads.

Masterpiece Arms BA Competition Chassis
Brux Heavy Varmint 26-inch, 1:8″-twist barrel
Remington 700 Action (custom bolt knob)
ECTuner (by Erik Cortina)
Kahles 6-24x56mm MIL Scope
MPA 1-piece 30mm Scope Mount

Barrel Tuner by Erik Cortina — Fits Behind Muzzle Brake
This rifle features a barrel tuner designed and crafted by Erik Cortina. You can the ECTuner alone, or, as you can see, the ECTuner can be fitted BEHIND a muzzle brake. Erik tells us: “The ECTuner allowed me to tune the barrel to my ammo rather than tuning the ammo for barrel as is done when reloading. With the tuner, there is no need to try different brands of ammo as they can all be tuned to shoot as good as possible in my rifle.”

MPA Chassis Configuration Guide
Erik’s “budget” PRS rifle employs a MasterPiece Arms (MPA) BA Competition Chassis with Rapid Adjustment Technology (RAT). This MPA Arms Video shows how to set up an MPA Chassis to suit the owner:

Air Rifles: A Buyer’s and Shooter’s Guide

pyramyd air airgun field target pnematic

We like air rifles both for fun shooting and for competition. However, so many options are now available that is easy to get overwhelmed with the choices. Thankfully, there is a good book that helps air rifle shooters make informed decisions about air guns and accessories. Steve Markwith’s comprehensive resource, Air Rifles: A Buyer’s and Shooter’s Guide offers a wealth of useful information. This 154-page book is now available for $12.95 (paperback) or $9.95 (Kindle).
