Perfect Example of Why Numbers Matter
And that you can be a perfectly competent shot with zero understanding of what's happening
November 06, 2023

There is a thread on the Hide that brings back the topic of drop tests, but in an even sillier way than is typical.  Someone over there has already tried to get me to chime in, but I think I will skip that thread.  I have tried to explain why this is stupid on the Hide before, but was mostly met with an online equivalent of a blank incomprehending stare.

I will give it a shot here for albeit briefly, since it is a good follow-up to discussion I had with SlavGuns on Arken optics: https://darklordofoptics.locals.com/post/4779477/starter-precision and starter precision scopes.

This most recent Hide has a link from a gentleman who has an Arken EP5.  He shoots a plate at 1000 yards, then takes the scope off the rifle (it is in a QD LaRue mount, which is already not a great idea), chucks it 25 feet onto soft dirt, walks over to pick it up, mounts it back on a rifle and hits the plate again.  Then, he proudly announces that the Arken EP5 is good to go.

I have no idea who the gentleman is, so none of this should be viewed as an attack on his intelligence or integrity.  Smart people say and do stupid things all the time.  This is CLEARLY not something he has ever bothered to think about.  He likely saw some knuckle dragging lunatic on Youtube do this.  It probably looked cool.  A lot of this stuff makes sense if you do not bother to think about it.

There are several problems here.  The most obvious, aside from the fact that his "test" is just stupid, is that he looked at one scope and pronounced EP5 as "good-to-go". 

I just had a livestream with SlavGuns and out of six Arkens he had, three had problems, including some Arkens.

All of this is anecdotal data, but six data points are a lot better than one (deeply flawed) data point.

I have an Arken scope here.  It works great.  However, having talked to many people with Arken scopes, I think my experience with it is not representative.  When I talk to people who buy Arken scopes and who actually shoot, they tell me they see these go down in every competition they have been to.  Arken did a great job getting many scopes out there.  Now, they need QC and engineering to catch up with their sales and marketing.   

As far as the test itself goes, aside from the fact it is meaningless on a sample of one, it really does nto tell us anything. If you drop your rifle in the field, you should check zero.  If you have a decent quality scope and something shifted, seven times out of ten, it is the mount.  If you have a QD mount, it is probably nine out of ten or higher. 

As far as the impact itself goes, what people at rifle scope QC departments do to their products to check for zero shift is orders of magnitude more severe than chucking it onto the ground. 

Now, intentionally dropping the whole rifle with the scope is equally stupid since depending on the exact angle, what it hits, the exact type of mount, how well the whole thing is bedded, the types of turrets the scope has, where the rings happen to be, whether it is fast focus or traditional eyepiece, and a myriad other factors, you can get very different results.  With this attempt of a test, it is impossible to correct for all the variables, so when something goes wrong you have no idea what the root cause is. If nothing goes wrong, you have no idea if that is repeatable.

It does provide ample opportunity to rig the results to get what you want.  I once saw this test set up so that the product of a company the reviewer hated was in a QD mount, while the other product was in a fixed and properly torqued mount.  Naturally, the QD mount shifted and it was blamed on the scope.

All influencers claim impartiality and all that.  However, most of them live off of affiliate links and it is very hard to not bias toward what pays you more.  That is one of the reasons I was so happy to see SlavGuns raise the issue of 50% failure rate on his Arkens.  A little intellectual honesty goes a long way.

That is also why when posting affiliate links, I tend to prefer to deal with large companies that carry many brands, like Brownells or Eurooptic, for example.  It makes no financial difference to me which product I recommend, and as the memebrship here grows, I hope to phase out the whole affiliate business completely.

I do not think most reviewers/influencers rig the results (although some clearly do, just based on how they position the cameras and do the tests).  

As the (slightly modified) saying goes, "never ascribe to malice what can be adequately explained by incompetence".

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.

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 ...

Livestream later tonight and upcoming raffle

I made it back to some semblance of civilization in Colorado, but only for one night. Tomorrow, we will head into the Rocky Mountain National Park for a few days of camping and I am not sure how spotty internet connectivity is going to be.

My original plan was to do an impromptu sort of a livestream on my takeaways from the match I just shot, but given what has been happening in the Middle East, it is probably more pertinent to talk about that.

I am going to start by rehashing a little bit the narrative of how we got to the current situation and where the latest events are likely to taking us.

As far as the match goes, they did a random drawing for the prize table, so Ethan and I both walked away with something. Since both of us are very much industry insiders, I am not sure how appropriate it would be for either one of us to keep stuff off of the prize table.

That means that I will raffle off the items we picked up during the next couple of livestreams.

One is a $2000 OFF certificate for...

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.

Please vote and add a comment if there is something specific that interests you or your reasoning.

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

Telson optics offer a 15% site-wide sale on everything that is stackable with my DLO6 discount code that gets you additional 6% off.
https://www.telsonoptics.com/?coupon_code=dlo6
To date, I have looked at the Toxin 3-18x50 very carefully and like it quite a lot. I have had a little bit of hands on time with the 5-25x56 and 5-32x56 as well, but not enough to form strong opinions. They do seem like nice scopes.

Opticsplanet has 13% off with "TYDAD" coupon plus 2% bonus bucks. https://alnk.to/90B3faG

Primary Arms has a pretty extensive list of discounted items posted already https://alnk.to/2uJ0X2f They usually add something new to it as they build to the actual holiday, so if you are looking for ...

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.
