Word of the Day
ultracrepidarian
June 02, 2023

I am not planning to start a "word of the day" article series, but I stumbled onto a word I did not know.  If I do not find a way to use it, I will forget it and this one is too good to let go.  There are a few complicated words that are used when you want to call someone a moron without them catching on.  This is one of them.  

Ultracrepidarian

If there is a word out there more apt for describing modern world where hiding behind your keyboard is the easiest thing in the world, it is this one.  We were talking about the critique I made of one of the Youtube videos during the livestream yesterday, so it has been on my mind: https://darklordofoptics.locals.com/post/3528032/can-you-make-a-good-1-10x-scope

According to dictionary.com, here are the origin and the meaning.

Origin:
First recorded in 1800–20; from Latin ultrā crepidam (also suprā crepidam ) “above the sole, beyond the sole,” from adverb and preposition ultrā (see origin at ultra-) + Latin crepidam (accusative singular of crepida ) “sole of a shoe, shoe, sandal” (re-formed from Greek krēpîd-, stem of krēpís “man's high boot, half boot, shoe”) + -arian; in allusion to Pliny the Elder's adaptation of the retort that the Greek painter Apelles (360?–315? b.c.) made to a cobbler who was critiquing Apelles' work, nē suprā crepidam sūtor jūdicāre “let the cobbler not judge above the sandal”; cf. the English proverb “let the cobbler stick to his last”

Meaning:
noting or pertaining to a person who criticizes, judges, or gives advice outside their area of expertise.

We live in a world where ultracrepidarians generate enough noise to make discovery difficult.

There are few words like this I use on a regular basis.  My favourite is probably supraclavicular.

A while back, my boss was a very capable engineer with one hell of a sense of humor (a very useful thing for engineers and scientists since we tend to take ourselves a little too seriously).  I once noticed that in a meeting with some upper management types, the beancoutners were talking about something fundamentally stupid that we were asolutely not going to do.  I explained, the best I could, why we should not be doing that.  I was very adamant we shouldn't for two reasons: 1) it was profoundly ignorant and stupid, 2) it would take me two months to work through all the bullshit if they forced me into it.  I am neither a nice man nor a tolerant one and my boss (Richard) noticed that I am getting a full lungs of year to explain to the upper management guys what exactly they can do with this idea.  In retrospect, that would have been career limiting, but I was too young to care.  Richard smoothly inserted himself into the conversation and explained to them that there is fundamental supraclavicular problem that makes ths idea non-viable.

Apparently, noone knew what "supraclavicular" meant and noone was going to fess up to that.  The subject was dropped.  As we were walking back to the lab, I sked Richard what he meant by that word, since I didn't figure it out either.

Richard originally planned to become a doctor, but dropped out of medical school after a couple of years since it clearly wasn't for him.  He foudn his calling in the semiconductor world.  He did pick up a few words there. 

Supraclavicular means "above the clavicles".  What is above the clavicles? Mostly your head.  A supraclavicular problem is a problem of understanding and understanding only. 

It is a somewhat subtle thing, as is "ultracrepidarian".  It does not necessarily mean "full of shit".  It can simply means that a layman's opinion is passed off as an expert opinion.  More dangerously and very commonly in the last few years and opinion of an expert in an unrelated field is passed off as an expert opinion.  A lot of our response to COVID was exactly that.

Vortex Defender XL Green

This is the second time Vortex' Defender XL crosses my path. I was very impressed with the original red dot version, so I was curious to see how the one with the green dot works for my eyes.
To get the details, see the attached video.
The cliff's notes version is that I am just as impressed with this one. In terms of collimation quality and parallax control, it is quite exceptional.

Primary Arms HTX-1 US Made red dot sight

I've had this RDS for a bit over two months now and I am beyond pleased with it.
Despite some spirited abuse, it keeps soldiering on.

It is a very nice RDS and being fully made in the US does not hurt either.

Delta Stryker 3.5-21x44 Wrap-up

This scope comes up a lot since I really like the configuration. It is time to do a final wrap-up of it.

It is one of my favourite scopes on the market today, especially for the money, since I naturally lean toward general purpose-ish designs. Still, while the 3.5-21x44 Stryker is relatively compact and light, it still clearly leans toward the precision side of things, which suites me very well.

Labor Day is upon us...

As we head into Labor Day, we will all be bombarded with a huge number of emails indicating impending discounts of all sorts.
I am not even going to pretend that I have the bandwidth to go through it all, but if I see something worthwhile, I'll post it here. This will remained pinned to the top of the feed for a week or so.

The first nice deal that crossed my path here is steep discount on the original version of the FFP PLxC LPVO from Primary Arms. https://alnk.to/5Q7R6eK
Now that the new version with nuclear bright illumination came out, it looks they are closing out the original. It is a lot of LPVO for $1100 and the version with the Meters reticle is my favourite. You can easily make it work for imperial units.

Tract has the TORIC100 coupon code that gets you $100 off any Tract Toric optic. https://tractoptics.com/toric-uhd-30mm-2-5-15x44-ffp-illuminated-mrad-eagleman-long-range-hunting-rifle-scope?ref=ILYAKOSHKIN
The coupon codes are stackable, so if you also use my DLO discount code...

I was a bit confused at the beginning but this is a new Model looking at the turret compare to old LH2-10x40,
Any news on this ?

Updates, deals and new review items: PLxC RDB, Zeiss Tripod, etc

As the week is coming to an end, I find myself in an unusual place: home.

I plan to be home between now and September 1st when I have to go to Israel for ten days, returning on the 11th (dayjob stuff).

For the last couple of months, between family vacations, work and a couple of matches, it seems like I only spent enough time at home to check zero on my 6.5CM Fix and head out again (it has not shifted, thank you Area 419 mount).

I have a lot to do during the next two weeks, but I will try to take some pictures, film some footage and release it as I go along. I can edit videos on the plane or in Israel just about as well as I can at home.

While generally, I am very picky about what I accept for review (given my bandwidth limitations), I do have a few new things here worth talking about.

One is Primary Arms new PLxC RDB 1-8x24 LPVO. It is essentially a version of the original FFP PLxC LPVO except with different reticle illumination technology. The new model utilizes diffractive reticle illumination (same style ...

Well, that was a doozy...

My original plan was to try to set up a hunt where my daughter will have her first memorable hunting experience without working too hard.

The choice of the pronghorn hunt was largely based off of my experience in that same area last year.

The way it went last year was quite straightforward.  We drove around until we saw a large pronghorn buck.  It was a solitary animal that decided to lie down in an open area to relax.  We made a short stock, crawled the last hundred yards or so, found a good spot about 350 yards away from the pronghorn and made the shot.

https://darklordofoptics.locals.com/post/6034347/well-that-was-a-nice-morning

This year, when I decided to take my daugher on the same pronghorn hunt on the day of her 14th birthday, I figured it will be somewhere along those same lines.  It kinda was, but not quite.

Still, it worked out nicely.

In the pciture:

Q Mini-Fix with 6ARC 16" Proof Research carbon fiber barrel

Q Jumbo Shrimp supressor

Gunwerks Elevate 2.0 bipod

Telson Toxin 3-18x50 riflescope

Leica Geovid Pro AB+ LRF binoculars

Pint-sized sticky Gamechanger bag

Unnamed pronghorn buck.  It will likely get a name once it's skull is euro-ed and is hanging on the wall.

Steiner C35 Gen2 Mount
from Annex Defense

The production version of the Annex Defense's mount for the Steiner C35 Gen2 thermal Clip-on is finally here.  At $1600 (when this is published), the clip-on is an absolute steal.

I've had it for a few days, but, me being the good old paranoid me, I spent some time shooting with it before posting anything.  I had a couple of days with it prior to last weekend's match in Montana and a couple of days after.  Another to pop it on and off a few times and get a couple of hundred rounds of 6.5Grendel through the gun to see if anything shakes loose.  So far so good.

The C35 Gen2 clip-on is sitting on my 6.5Grendel AR as a part of a long running "Only One" project that I have.  It pairs perfectly with the Steiner H6Xi 2-12x42 scope.

Here is what comes in the box from Annex Defense:

The order in which the whole thing comes togethe is pretty stragihtforward:

-slide the thermal washer onto the threaded interface extending out of the back of the clip-on

-spin the mount itself onto the threaded interface (the mount is threaded on the inside) until it can go no further

-rotate the mount so that the clip-on is properly lined up to the picatinny clamp

-once you are happy with the alignment, use the three nylon tipped set screws (you'll need an allen wrench for that) to lock in the position of the clip-on in the mount.  You need very little torque on the set screws.  They are there for one reason and one reason only: to keep the mount from spinning when you tighten the timing nut in the next step

-spin the timing nut onto the threaded interface of the clip-on to lock the mount in place.  You should not need the timing nut wrench, but one is in there just in case.

Here are the pieces laid out in the order in which you will need them.

When you are done, it should look like this:

Note that the mount normaly comes with two T20 screws.  I am using two thumbscrews instead, since I am popping the mount on and off all the time.  It seems to be staying put with the thumbscrews just fine.  I am hoping Annex will offer the thumbscrews as an option.

It is not quite an equivalent of a QD mount, but we needed something with an extremely low profile clamp to fit under scopes with fairly large objectives.  As is, the mount works with most scope that have objective lens diameter of 50mm or less.

I am using with with Steiner H6Xi 2-12x42 and the two work together exceedingly well.
