HET, Part 7: The War of the 50mm glass. Setting the stage.

The title of this post is my attempt at theatrical exuberance. If that was not clear before, this should really clarify why I never had a snowball's chance of a career in performing arts. Some people are just born to be nerds, I suppose.
I have mentioned here and elsewhere that I am kicking of a new High End Tactical (HET) comparison. Interestingly, although very few people are actually willing to spend this much money on these, quite a few people want to know what the pecking order at the top is and whether one is significantly better than all the others.
I'll try to rank them in some sort of a reasonable way, but the choice between the options is usually not the same for everyone. Barring some potential surprises (and those are usually not good surprises), everything on the high end is very good. However, riflescope design is an art of compromises and different manufacturers make those compromises in different ways. As is most often the case in real life, the answer is more nuanced than a simple ranking from best to worst. The biggest driver for the comparison is the introduction of March 4.5-28x52 and Zeiss LRP 3-18x50. I am really curious to see how they stack up against the competition.
I originally decided to put this together because I was curious how the new March 4.5-28x52 stacks up against the competition. 52mm objective is sort of an "in between" size, but it is closer to 50mm than 56mm and since the scope is compact, it really fits better with 50mm designs.
I have spent quite a lot of time with a near production prototype of this scope and I know it is very nice. What I do not know is how it stacks up against the competition.
While we are talking about nuanced answers, if you were to ask me what the best precision oriented high end scope out there for everything across the board is, I can tell you right off-hand that this March is going to be in the top 3, simply on the strength of it having very wide FOV broadest magnification range of the group, reasonably compact size and light weight. I also have the background knowledge of what they changed compared to the prototype I looked at. However, if you were to ask me whether you should get this new march or the ZCO 4-20x50, I would really struggle with the answer. The easiest would be to find out whether you often use magnification above 20x, which reticle you prefer and how much value you put on locking turrets. Based on answers to those recommendations I can make a perfectly reasonable recommendation, but the dirty trick here, so to speak, is that since I know these two are really nice scopes and whichever one I recommend, you are not going to be disappointed. What I can't yet offer is a sufficiently nuanced answer on how they compare optically and optical comparison will be a really significant part of this effort.
I will obviously carefully look at the mechanical quality, both objective and subjective, but I really do not expect anything within this price range to give me any objective mechanical problems. That is definitely something to check though. Feel will be different, of course, and that is another potential differentiator.
Normally, when I do these, I make the announcement, then vanish into my "dark lord lair" for a few months only to emerge with the results.
I plan to do it differently this time. There will be supporter-only updates as I go along, so that I can get some feedback here and there and make sure I dig into the details that matter to you. Also, if any of you are within a reasonable driving distance of me, we can potentially arrange a meet somewhere for you to look at the scopes yourself.
Here are the contenders:

March 4.5-28x52 with FML-TR1 reticle (on its way here) https://bit.ly/32qOUhj
Zeiss LRP 3-18x50 (should be here in a couple of weeks) https://bit.ly/3nNYZNx
ZCO 4-20x50 with MPCT3x (already here)
Tangent Theta TT315M 3-15x50 (has been here for a few years) https://bit.ly/3p22gs0
S&B PMII UltraShort 5-20x50 with P4F and DTII+ turrets (has been here for a bit). https://bit.ly/3CKequw
Steiner M7Xi 2.9-20x50 with Tremor3 rerticle (got here last week. They only had it with Tremor3, so I had no choice) https://bit.ly/3r5sw7t
US Optics 3.2-17x50 with JVCR (I already reviewed this one, so it will only be here for the optics part of the comparison; I know the mechanics work) https://bit.ly/3l9u9gJ

I also have a mystery contender, of sorts, that I had not mentioned before. I do not think it belongs in this group in terms of features or price, but optical and mechanical quality are very good. One of the things I am looking to figure out while I am doing this is where it fits between these $3k+ scopes and $1500-ish designs that I consider to be the best bang for the buck, like Vortex Razor HD-LHT 4.5-22x50 and Element Nexus 5-20x50.

Burris XTR PS Wrap-Up

The first Burris XTR PS scope I got my hands on landed here in the beginning of March.
That means I have been messing with this design for a bit under four months. That does not quite qualify as a long term test by my standards, but it is a fair amount of time and quite a few rounds shot, mostly 5.56 and 308.
I have both of the models of XTR PS and both work well.
https://alnk.to/3U3cZEC

For matches and such, I would lean toward the 5.5-30x56 version, but for general purpose use, the smaller 3.3-18x50 model does have an edge. You can shoot a match with it, take it hunting in the mountains or slap a thermal clip-on in front to go shoot some pigs. While not light weight, it is a very flexible design owing to moderate size and mid-pack magnification range.

As I said in the video, I think XTR PS is a meaningful step forward in simplifying how we shoot at distance.

I will provide occasional updates as I continue using the scope.

5x Prismatic Wrap-up

This is not the end of my commentary on 5x prismatics, but it is a wrap for an unintentionally very long term project I had. I spent an unhealthy amount of time evaluating these four prismatic riflescopes:
Element Immersive 5x30 https://alnk.to/gzXEPUr
Swampfox Sabre 5x36 https://alnk.to/aAPTubq
Vortex Spitfire Gen2 5x https://alnk.to/3co4hVD
Primary Arms SLx 5x https://alnk.to/2jOhnT7

Two are large prism designs. Two are small prism designs.

The order in which I list them above corresponds to the image quality, from best to worst, although there isn't a ton of difference between SLx and Spitfire Gen2. Purely on the merits of resolution, Sabre is comparable to them as well, but much wider FOV and forgiving eyebox does put it a step above in terms of performance (at the expense of about a pound of weight). Element Immersive 5x30 is a different beast optically and it should be at a higher price at which it sells. It resolves better, has higher contrast and widest FOV of the bunch. Side-focus adds ...

Blast From The Past: Millett ZoomDot RDS

I dug this thing up purely by accident. It has been a long time since I used it for anything, but I am thinking I should, especially as I work on a magnifier video.

MIllet's ZoomDot was a unique red dot sight that had auto brightness and variable dot size from 1MOA to 10MOA.

Early ones, like mine, were made in the US. Millett had some aspirations of selling these to the US military.

I do not think they got very far, then the company was bought by Bushnell and essentially shut down after a little bit. At some point, the manufacturing for the ZoomDot moved to China and it was not really the same.

Independence Day, 2025

Publishing a "Happy Independence Day!" a day after independence day is probably bad form. It is also bad for posting affiliate links. Everybody and their grandmother is having discounts and I am not posting any links. To be honest, I do not particularly like posting general links and I simply did not have time to dig through everything and come with specific product links.
Still, if you plan to be buying something from one of the retailers I have an affiliate account with, I would appreciate it if you were to start with one of my links listed in the FAQ: https://darklordofoptics.locals.com/faq

I started writing the more substantive part of this post yesterday, but got sidetracked with thinking about the origin of the ideas that make America and ran out of time. I was only able to get back to it now. I suppose, better late than never.

We live in the world that, as far as the details go, is dramatically different from the world of the founders of the United States.

For the majority of this ...

This is a good deal:

Hi Ilya,

For many years I have been looking for a new spotting scope that has an FFP mil reticle for accurately calling corrections.  I have the angled version Kowa TSN-883 with 20-60 eyepiece that is great except it doesn’t have a reticle so the correction calls are not as precise or as fast as they could/should be. An ideal reticle would have a crosshair or L with a grid off of center but a simple crosshair, L or a tree would be sufficient.

I really like dual focus (can settle for single focus) that uses the small knobs that rotate very easily/smoothly so the scope can be focused on a v-bag while staying on target when it's impractical or a hassle to use a tripod. 

I also like an angled eye piece because it’s easier to establish a comfortable position in many situations as compared to straight eyepiece where you need to be directly behind the scope.  

I haven’t found anything with these attributes with max magnification and glass quality at least “good enough” for clear ...

A morning with a chronograph

When I tell people that I am using Hornady's factory ammo for matches, I get occasionally surprised looks.  Occasionally.  Most of the time, I get fairly condescending looks from handloaders who would not let a factory round pollute the chambers of their precision rifles if their lives depended on it.

To be fair, if I had the time, I might be reloading as well.  I might be able to do better than modern factory ammo, but the truth is that I am not a quarter MOA shooter, so a lot of that would be lost on me.  The UKD matches I fidn most interesting can be done by a competent shooter with a 1MOA gun.  I am working on that first part.  I reload when I have to, but if I can get factory ammo that's not outrageously expensive and that shoots well, I will go with that every time.

I looked around and realized that I have about 600 rounds of Hornady 147gr 6.5CM factory ammo from two lots.  400 rounds from one that I will use during the match later this month.  The remainder I will likely use up practicing prior to that.

I woke up early and snuck out to the range while my family was still asleep earlier today.

I set up in the 100 yard tunnel we have.  I took my four shots to zero with the lot I plan to use for the match.  Then I fired a six shot ~0.7MOA group.  That's accurate enough for my purposes.

Here are the chronograph results:

It is slow, but accurate and consistent.

Then I shot a five round group of Hornady 147gr ammo from the other lot.

Both of those lots are not too shabby for factory ammo.  POI was within 0.2mrad between the two lots, all laterally.  

 

I had some other ammo on hand, so I fired two five shot groups with Berger 144gr hybrid target ammo and Sako TRG 136gr.

Here is what I got for five rounds of Berger:

That's not a ton of statistics, but it is a data point.  The group was ~1.1MOA

 

Here the data for the Sako TRG 136gr ammo:

This ammo showed some mild pressure signs, but not too significant.  

Again, this is not a ton of data, but Hornady is looking pretty decent here.

I'll repeat the zero retention and consistency tests a couple more times between now and June 18th when we head to Wyoming.

I might pick up a couple more boxes of Hornady 147gr from a different lot to get some more data.

More to come.

First PRS Match is behind me
High Noon at Del Norte

My first PRS match is officially behind me.  It was, I think an officially sanctioned regional PRS match at the shooting range called Del Norte about an hour from me (just east of Rio Rancho).
As I discussed previously, rather than using the rifle I originally prepared for it, I ended up having to change gears at the last moment and slapping a 5-25x56 Tangent on my daughter's 6ARC MiniFIx.  A lightweight 16" Proof barreled 6ARC is not an ideal set up for PRS competition, but, in the grand scheme of things, the rifle did hot hold me back at all.  I had a couple of weights that fit the Q-cert handguard, so I slapped them on there as well, which got the rifle to right around 12lbs.  The balance point was almost where I want it, but not quite.  In all other ways, this was a very handy rifle to shoot.  I am actually thinking of getting a couple more weights that I can stack on it (Sawtooth weights are stackable), so that I can shoot some future local matches with it.  It shoots Hornady's Black 105gr ammo very well (it also shoots 108gr ELD-M and 103gr ELD-X well, but I had a larger supply of Hornady Black ammo on hand).

It chrono'ed pretty consistently for factory ammo.  Here are the measurements for a 20 shot group.

If I were to take out the fastest shot, SD drops down to 8fps.  

In terms of wind performance, it is a 5mph rifle, so slightly better than the 308 ammo I was going to use originally, but not as good as the 6.5CM that was my intended match rifle for this year (we make plans, but then life happens).

I do have to admit that I really enjoyed shooting the match with the MiniFix.  So much so, that I am seriously thinking of building another one for myself, since this rifle is technically my daughter's.

The closest shot we had was a bit over a couple of hundred yards.  The furthest was around 1150.  That was a bit challenging for the 16" barreled 6ARC, especially since the terrain there is tricky and wind is doing strange things.  Morning was relatively quiet wind-wise, but then the wind becamse gusty with changing directions.

It was a one day match with about 30 shooters (six squads) and ten stages.  The 17 year old kid who won the match was in my squad with his dad.  Apparently he is on the US team, so it should not be surrpising that he won.  He was very good.

Overall level of the shooters in the match was quite good.  I really was not sure what to expect.  Somewhat paradoxically, the only matches that I have shot in so far are the much larger two day NRL Hunter matches.  In those, I am just out of the bottom third in terms of skill level.  In this match, it was pretty much in the same spot, I think.  

The terrain was a little bit like Cameo, I think (I have been there, but not shot there), with some angle changes and sufficient vegetation to make getting on target occasionally troublesome.

Getting back on the horse, little by little

My original plan was to do a livestream on Thursday of this week, but I think I'll push it out to next week.  A few days at home is doing wonders for my recovery, but my voice is still not quite there.  I do not think any of you are looking to listen to me cough for two hours straight.

Also, I am going to try to shoot that local PRS match this coming Saturday, so doign a livestream next week after the match is likely to be more productive.  It is my first one, so I fully expect that I will screw it all up.  It should be a good learning experience.  I do not have a dedicated PRS rifle and I am not looking to set one up jsut yet.  If I like it, I'll put something together, but as far as competition goes, my focus is really on UKD matches like NRL Hunter, Competition Dynamics, etc.  My 6.5CM is not back yet, so I'll just shoot it with my 308 FIx.  It is not ideal, but it will do just fine for my purposes.  I am in no danger of winning anything either way and this will stress my ability to read wind.  A secondary purpse here is that I am not 100% certain what rifle I will take on a mule deer hunt with later this year, but it will be either something new to test or this 308.  Now that I think about it, the 308 is going with me regardless either as a primary rifle or as backup.  The rifle shoots, so if I miss, I know it is on me.

For the match, I have Burris XTR PS 5.5-30x56 scope on the 308 Fix.  I think the way they did the heads up display in these is a meaningful improvement over conventional riflescopes.

https://alnk.to/d3EjPHC or https://alnk.to/8iVRlGN

Optically, I think XTR Pro is a little better, but the EO integration in the XTR PS is, I think, in advantage.

In parallel, I am looking at the replacement AAC ammo (they replaced the faulty ammo and I have chrono results on it) and testing the optics of the 40mm scopes in parallel.
