Delta Stryker 1-10x28FFP
First Impressions
October 03, 2023

Let's starts with a disclaimer: through the scope pictures were done quick and dirty with a handheld cell phone.  In the course of the review, I'll do a proper through the scope video and pictures.  These are just here to give you an idea of the reticle size.

Another disclaimer: I do not think it is for sale anywhere yet, but it is coming.  Annex Defense has a pre-order goign on their website: https://annexdefense.com/delta-stryker-hd-1-10x28-rifle-scope-do-2517-1-10/

This scope is interesting.  It is very full featured in an attempt to make a "do everything design" from CQB to DMR use.  The interesting thing is that it does all of that pretty decently.  Conceptually, it is pretty similar to March 1-10x24 Shorty.  March is a little smaller, a little lighter, has zero stop and it a bit more expensive.  Delta has wider FOV, lower profile turrets, more forgiving eyebox and lower price.  It is about three ounces heavier and couple of inches longer.  

Both have side focus which makes them stand out from the field.

The reticle in the Delta is conceptually similar to the EOTech with a very large circle that disappears from the FOV by the time you get to 6x.  On 1x, however, I found it to be very useful.  THe circle is 69mrad in diameter, which is quite helpful on low power.

That allows the reticle in the center of it to cater a little more to the DMR end of the market, although there are still some high visbility features to help on low power.  I'll do a full reticle workup separately.  In the meantime, here are some pictures.

1x, illuminated and not.  Illumination is day visible, but not nuclear bright.

Without illumination, it is not ideal on 1x, but surprisingly usable.

On 5x, the large circle is right at the edge of the FOV which looks a little odd, but not too intrusive.


But on 6x, the big circle is gone and the scope is esentially in its DMR mode:

On 10x, this is a pretty solid precision reticle with a few clever features: note the difference in dot size through the tree (full disclaimer: I did not design this reticle, but I had a chance to offer input).

My apologies about the picture quality.  The shading is purely due to camera alignment.

Both windage and elevation turret lock.  There is no zero stop.  Turrets are nicely low profile which I like.  I did a quick tracking test and they seem consistent.

Illumination is integrated with the side focus turret.  Side focus has a detent on 100 meter setting so you can return to it by touch.  It focuses down to 10m, which I really like for dry practice.

The objective is 28mm which should help a little in low light, but I have not yet tested that.

Daytime image quality is very good and side focus really helps when the distance is fairly close or very long.

All adjustments work as they should without any excessive resistance.

Eyebox is nicely forgiving despite fairly wide 22.3 degree apparent FOV.

Overall, it sure comes off as an exceedingly competent design.  No issues of any sort so far.

I'll keep you up to speed as I spend more time with it.  I put onto my DMR-ish AR-15 where I think it is most at home.

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.

Scout Scopes: Burris 2.75x20

Scout scopes are almost like a forgotten art form these days. There is an occasional discussion either on how they are the greatest thing since sliced bread because 1) THE colonel said so 2) if you do not think they are, refer to rule number 1.
Alternatively, the prevailing thought is that they are completely useless and if LPVOs existed in Jeff Cooper's time, there would never be such a thing as scout scopes.
The truth, as is usually the case, resides somewhere in the middle.
Scout scopes do have their place, but they are definitely a niche product. It is, however, an interesting niche.
Scout scope pickings are relatively slim in terms of what's on offer.
Leupold makes a 1.5-4x28 https://alnk.to/gKSibYj
Burris makes a 2-7x32 and 2.75x20
Vortex has a 2-7x32 in the Crossfire line
There are also a few out there from UTG, Aimsports, etc.

I strongly lean toward compact fixed power designs, so Burris 2.75x20 https://alnk.to/cSJCBQx is probably my favourite and is the subject of this ...

Integrix M1 MRAD Reticle in the 3-18x44

Wind was really making things difficult, but at least this gives you a look at the reticle.
It is a respectable design that is conceptually closer to SKMR reticles than to the ones I usually gravitate to. They also have an M2 that is, I think, a little better.
In the grand scheme of things, the M1 did not take me long to get used to and it is not giving me any real issues.

Current Events

Gentlemen,
I am trying to decide if I want to do a livestream to discuss the current events in the Middle East.
Every time I do that that, the feedback is rather conflicting.
If I do, that will be tomorrow evening (17th), around 7PM Mountain Time.

Father's Day Deals

It looks like all the different retailers have sufficiently recovered from the Memorial Day to swiftly transition into Father's Day.

It is not quite a Father's day thing, but Norma usually ahs something interesting on sale. This time it is rather good quality 9mm https://alnk.to/4fSBmuh

Riflescope Mount recommendations

We have had enough discussions on riflescope mounts that I figured I should have at least a small number of the ones I recommend summarized among the riflescope recommendations.
There is a huge number of mounts out there with many very serviceable ones.
This will be more along the lines of the ones that I actually use, rather than an exhaustive list of the good ones.

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.
