I was able to take the new SS 5-20X50HD out to the range today to sight it in and compare it to the old scope as well as the scope from another rifle.

I tested it against the Sightron SIII 6-24X50LRD(target dot) and Leupold Mark 4 4.5-14X40. I'm replacing the Sightron with the SS and mounted the new scope last night. Here's a picture of them at the range:

I was only able to go to the 100 yard range for the testing, and used target paper and target spots to test for resolution and contrast. The target had a bar code on it which was very helpful for this.

It was immediately apparent that the Mark 4 was out of it's league here. This came to no surprise as it has a smaller objective and previous reviews of it have been less than stellar. I however like how compact it is, especially the small eyepiece, which is why it resides on my M1a.

At 14X both the Sightron and Super Sniper could resolve the smallest lines on a Birchwood Casey orange target. The Mark 4 could not.

Here is a picture of the target so you know what I'm talking about:

It was very sunny day but the temperature was a mild 80. The Mark 4 showed mirage at 14X. It wasn't enough to have to turn the magnification down, but was very evident when looking at something ground level. Neither the Sightron or Super Sniper showed this, even at Max (24 and 20) magnification. This was surprising to me as I thought mirage appeared regardless of optical quality, and that it was only effected by magnification and environment.

I did not spend much time testing at 14X since I knew the Mark 4 didn't really hold up to the other two. I also meant to do low magnification tests for field of view and such, but I forgot.

Most of my time was spent testing the Sightron against the Super Sniper at high magnification. It didn't take much time realize the Sightron was clearly designed for benchrest shooting, while the Super Sniper was more of a tactical scope.

For one: the reticles are very different. The Sightron's 1/4 MOA target dot is SUPERB for shooting at paper. Not only does it not cover it much of the target, but it is much easier for the eye to align two circles(the reticle and the target) than it does a crosshair and a circle. If I were shooting a benchrest competition, I would pick the Sightron based on the reticle alone.

Another feature that separated the two was the parallax adjustment. The Sightron has a much longer field of travel, ideal for fine adjustment. I noticed while looking at a tree approximately 300 yards away that I had a ways to go before infinity. This was not the case for the Super Sniper. The Parrallax on the Super Sniper is marked in distances, and the amount of travel to go from 200 yards to infinity is fairly minimal. I suppose this is adjust for parallax quicker in a tactical setting. My old 16X super sniper was much the same as this one in that regards. I prefer the Sightron's as it is easier to get the best picture and for fine tuning. I suppose the Super Sniper's is quicker if you just want to get it "in the ballpark", however I still see that as an area for improvement on the scope. I don't have anyone shooting at me though.

As far as construction is concerned, the Super Sniper is considerably beefier than the Sightron. I definitely feel more confident that I won't break the SS than the Sightron. I have dropped the rifle a couple times with the Sightron attached however and it held up just fine. I have no doubts that the super sniper will take much more abuse.

I spent damn near an hour looking through the two scopes and comparing them side by side. I spent almost 5 minutes just setting the parallax to what I thought provided the clearest picture. At 20X the Super Sniper JUST BARELY edged out the Sightron in resolution. The super sniper was at max magnification whereas the Sightron I just set to where it said 20 on the mag ring, which aren't always accurate. I also set it to where it was clearly below 20 (19.5 or so) and the Super Sniper had better resolution. When I set the Sightron to just above(but clearly above, 20.5-21 or so), the Sightron showed more detail. It was that close. At 24X I could see more detail than the SS at 20X. Again, I was looking through for almost an hour at different objects to come up with this. As far as contrast goes, the Sightron won out in that regards, again just barely. At 20X, I could see the individual barcode lines better than on the Super Sniper.

The Super Sniper seems brighter, but that is a test I will have to do in a darker setting. I have tested the Sightron against a Weaver EMDR at night and the Sightron thoroughly trounced the weaver at light gathering, so that says something for the Super Sniper. There was a slight amount of chromatic aberration present in both scopes but not enough to compare with one another. The color hues of the Sightron are on the warm side, I prefer the slightly cooler colors of the Super Sniper. Actually the Mark 4 displayed the best colors in my opinion.

Tracking in the Sightron has been spot-on, as was the case for the Super Sniper. I was hitting center bull on my second shot. I did not do a box test because I couldn't measure out exactly 100 meters. Tracking on the Mark 4 has been sketchy and I am thinking about sending it back to be looked at.

In the end, I am very pleased with the Super Sniper and not disappointed in the least bit that it's glass wasn't a huge step up from the Sightron's (I didn't expect it to be). I appreciate the addition of FFP and all the new features, and that's what I upgraded for.
 
Re: SS 5-20HD vs Sightron SIII vs Mark 4 Review(long)

Few things I forgot the mention:

Eyebox, both are great. When I had the Sightron mounted on a rifle and the SS off, I thought the Sightron's was better. When I had the SS mounted and the Sightron's off, I thought the SS was better. I would have to get the two both mounted to do a fair test.

I really like the SS's diamond reticle. The diamonds look like hashes at lowest mag and are perfectly usable. This was not the case for other FFP scopes I've tried. The SS reticle would be perfect if it had an open center or were open with a a .05mil dot.

The turrets on the two scopes are very different, I'm not sure which one I like better. The Sightron's are more tactile, but are much lighter to move because of the covered turrets. They are also 15 MOA/Rev. The SS's weren't quite as much due to the increased amount of adjustment per rev. Neither felt as good as a nightforce's. Then again, the Nightforce I'm basing it off of had 5 mil/rev.

Also, the 19 eyepiece butler creek seems a bit small. Not sure if the was the cap that I got, but I have difficulty closing it all the way.
 
Re: SS 5-20HD vs Sightron SIII vs Mark 4 Review(long)

Thanks for the review. Can you compare the eye box with the Mark 4? I know it is not in the running, but I am familiar with the eye box on it.

It will be interesting to see how folks like the diamond reticle after having a little time to use it.

I agree with you on the turrets of the SIII. For me, the covered turrets were one of the reasons that I got rid of it. I definitely would prefer the exposed turrets of the SS, although Sightron has since brought out models with exposed turrets.

Thanks for the time writing the review. You did a nice job.

I didn't look at them back to back, but I can tell you both were significantly better than the Mark 4. Keep in mind the Mark 4 only has 40mm objective though, and that will effect the eyebox.

In any case I'm not a fan of the Mark 4 eyebox. I can get a decent sight picture if I try hard enough at max magnification, but I hate how the eye relief changes A LOT when you dial it down. I did not notice this on either of the other scopes.

After messing with the turrets a little more at home, the SS turrets are growing on me.
 
Re: SS 5-20HD vs Sightron SIII vs Mark 4 Review(long)

thanx for the review, I have a SIII 6x24 and like a lot too, reading this makes the wait for my 2 SS 5-20 a little harder now.
cheers.
 
Re: SS 5-20HD vs Sightron SIII vs Mark 4 Review(long)

I can personally tell you about the Diamond Reticle. The whole reticle itself makes range estimation an absolute breeze. When I was out shooting last weekend, I did the range estimation from the reticle to the known size targets that I placed out through the gulch.

I have also now received a card from SWFA that outlines all of the reticle subtensions. AWESOME!! You guys are gonna love these things!!

Re: SS 5-20HD vs Sightron SIII vs Mark 4 Review(long)

Thanks for the review. I have one of the Sightron 16x SIII tacticals coming next week and a new SS 5-20 someday later I'm sure. Really looking forward to doing my own comparasin.

You were likely observing mirage caused by your M1A's barrel. It tends to heat up rather quickly, due to the small diameter. I've seen the same thing with my Mark 4 equipped M1A vs. my USO equipped Remmy 5R.
 
Re: SS 5-20HD vs Sightron SIII vs Mark 4 Review(long)

I just mounted the SIII on the M1A to compare eyeboxes (and because I'm questioning the Mark 4 holding zero). I looked out my window in failing light with the Super Sniper and the Sightron. The target I was looking at was the roof and chimney of a house about 100 yards away, as well as a pine tree about 300 yards away.

I have to say, I do not like the coarse parallax adjustment knob on the Super Sniper. The Sightron's finer knob with larger range of travel makes it much easier to get a perfect sight picture.

While the light is fading, and its an overcast day, its still not dark enough for either of these scopes as I could turn to max magnification with any problem or darkening. I would give the brightness edge slightly to the Super Sniper. I mentioned the Super Sniper not having as good a contrast as the Sightron earlier, and in reduced light, it really hurt the Super Sniper. At 100 yards, the image on the Sightron seemed to "pop" better despite resolution being the same. At 300 yards, I could tell a huge difference looking at pine cones. With the Sightron, they really stood out from the rest of the tree. Although they were still easy to spot with the Super Sniper, it wasn't as readily apparent. Resolution at both ranges was equal, although I had to strain more on the Super Sniper.

Both scopes showed a fair amount of Chromatic Aberration on a white vent on top of a dark roof. The Super sniper's was less noticeable though.

I get the feeling that the Super Sniper isn't taking full advantage of its glass. At 300 yards, my parallax was adjusted all the way to infinity at its clearest setting. Also, about 2/3 of the parallax adjustment is used for ranges 35-100, while only 1/3 is 100-infinity. I may see if the adjustment range can be changed on these.

The eyebox was another surprise as well. At 20X the Sightron's was better. The Super Sniper is mounted on a 700 with a near perfect cheekweld, whereas the Sightron is on an M1a who's cheek weld leaves some to be desired. The Sightron was simply easier to get behind. Both scopes have good enough eyeboxes to not matter though. I highly doubt anyone is going to be trying to shoot a close range moving target at max magnification.

I am still very satisfied with the Super sniper, and I think with a few minor tweaks, it will be perfect. It's resolution and light transmission is just as good or better than the Sightron's, which makes me think minor tweaks with the focus will optimize it.

I will take a look again tonight when its completely dark and see what they look like at minimum magnification.
 
Re: SS 5-20HD vs Sightron SIII vs Mark 4 Review(long)

Yes I have a SIII 8-32x56 with the target dot. And i have to say for an 800 dollar scope it has spoiled me.

I got an 3-18x50 IOR and after hearing how great there glass is I was disappointed with it at first. Since then I have seen many other "High end scopes", and I now realize, its not that the IOR glass isn't awsome, its that for the money SIII's are untouchable.

Also had my savage 12 F/TR fall right on the SIII out of the gun safe. The scope still tracks as good as a scope possibly can.

So if the SS 5-20 is close to a SIII with FFP, and a nice ret iam sold, and will be ordering one soon.
 
Re: SS 5-20HD vs Sightron SIII vs Mark 4 Review(long)

Very good review of the glass.

SS seem to have a 100% tracking record so I'm not worried about super intensive tracking tests just yet.

Thanks for that!

<div class="ubbcode-block"><div class="ubbcode-header">Originally Posted By: RichS</div><div class="ubbcode-body">Nice post and review. I'm considering a SIII 10x42 MMD. I wonder how that would compare to a SS 10HD?

Any idea when SCSC's new range will be done?</div></div>

Ilya made a comparison of the fixed 10Xs and noted that the fixed Sightrons were not up to par with the variable ones for some reason. I would choose the 10HD based on matching reticle and turrets though.

If you wanted to take a look through mine, I live just south of you.
