Sony MDR ZX110 Headphones

Sony pretty much invented Portable Hi-Fidelity Audio with the WalkMan back in the 1980’s. While one can debate the validity of cassette tapes as an audiophile format, you can’t argue that Sony has a history of offering some of the best affordable, high quality headphones for both professionals and consumers. I still use the same pair of Sony MDR V-150 Studio Monitor Headsets I bought 20 years ago for my video editing today.

In my ongoing quest to find the best “cheap” headphone I tried out Sony’s ZX110 heaphones. They come in a range of colors, I picked up a white colored pair on Amazon which were on sale for under $10 (regular retail price $15). They come shipped in a cleanly designed cardboard box. This is a nice step up from the usual vacuform clamshell packages of their competitors like Panasonic and JVC.

The headphones retained my V-150s design cues on the ear cup , while improving on their compact stowability. Cord was an ample 4ft long with good solid feeling amount of wire insulation for durability. The audio jack had a clever dimple design on a right-angled 3.5mm jack.

Wearing them, I found them to be more comfortable than my old V-150’s, which have to fit tightly on the head to reduce sound-leak along the ear pads. The ZX110 head a looser more light feel along the ears while providing decent sound isolation. The earpads are replaceable.

Audio quality was balanced but underwhelming compared to my studio headphones. Performance was very similar to Pansonic HF100’s with slightly weaker bass response but clearer in the mid-range. The bass was its weak point, sounding more rattling than thumping on a House music track. Those used to bass-biased power speakers, like Beats will be disappointed. But the overall balance was good and likely to be straining on the user when listening to spoken word, Classical, Jazz, or Acoustic Pop.

Overall the headphones were among the performers in the Budget sub $20 price tier. These headphones are available on Amazon. Please use my Affiliate link to support my work: https://amzn.to/3764DoW

Rim Sorting 22LR

After testing weight sorted cartridges of Federal Champion 22LR LRN and finding that they produced 60% smaller groups than non weight-sorted cartridges, I decided to test the other big old-school 22LR accuracy technique: sorting cartridges by rim thickness.

The thickness of the a 22LR rim can effect the amount of headspace of the bullet in the chamber. And presumably, the thickness could also effect the amount and burn rate of the primer inside it. Both of these factors could effect the velocity and stability of a .22 bullet.

For the test used a batch of weight sorted 22LR cartridges from which to draw my rim sorted samples from. All the cartridges I measured weighed between 51.3gr and 51.5gr. I put 50 aside as a control group and measured the rim thickness of the remaining cartridges and sorted them by rim thickness. A friend from my rifle club lent me his Neil Jones Rimfire Gauge tool which made the measurement process relatively quick.

For my testbed I used my same CZ 457 VPC that I used for the weight sort test. At the range, I set up 2 rows of 3″ paste up targets at 100yrds. I fired 5 rounds into each target for a total of 40 rounds of rim sorted and 40 rounds of my non-sorted ammo.

Upon inspection the target groups were each a bit different from each other but overall appeared relatively similar in size. Just how similar surprised me after I ran a photo through my phone’s Range Buddy App. On overage both the rim sorted and the randomized control group produced a 1.27 MOA average size. Identical.

RIM SORTED
1.03 1.28 1.61 1.16 MOA
Avg 1.27 MOA

RANDOM CONTROL
1.83 0.99 1.14 1.14 MOA
Avg 1.27 MOA

So it would appear that rim thickness plays an insignificant role in 22LR accuracy and performance. At least so far as Federal Champion LRN is concerned. My buddy who lent me his Rim Gauge told me as much when he tested his Match Grade 22LR for competitions. Were it not the case, I doubt he’d be lending me his gauge.

SVBony SV46 20-60×80

SVBony, the Hong Kong based maker of budget astronomical telescopes, sent me a their mid-range SV46 spotting scope to test and evaluate. I reviewed the SVBony SV28 a few months ago and found it to be good value in the sub-$100 price tier. The SV46 is a big step in features and a moderate step up in price.

This is 80mm scope is heavier and has a more robust and detailed build. It is IPX waterproof rated and its front lens cap was so well fitted that I seriously had a hard time pulling it off. It has the stacked coarse and fine focus knobs found in pricier high end spotting scopes. Its eyepiece was large, removable, and featured an independently turning magnification ring.

But for a sub-$500 scope there has to be a trade-off and in the SV46’s case, its in the optics. Looking through the glass I found softness around the other edges. At x60 there was noticeable purple fringe. In the USAF-51 resolution test, I was able to resolve down to Element 4 in Group 0 which is quite good for a scope under $500 but this sharpness only applied to the center of the image as the focus got significantly softer about a 1/3 out from center.

The It’s optics, while underwhelming, are on-par with similar scopes in this price tier and magnification range. The Athlon Talos has better glass but has less features and looks and feels cheaper in comparison. The SV46 has a well built tube, adjustments, and controls normally found on spotters twice its price. As evidenced by very tight seal on the lens cover, is extremely water tight.

PRO

  • Built in Sun Shade
  • Water tight seals
  • Built in eye-cup
  • Fine and Course focus knobs
  • Indexed mounting ring

CON

  • Shallow eye-relief
  • Not sharp from edge-to-edge
  • Chromatic aberrations

CVLife M-Lok Bipod

The CVLife M-Lok bipod is a Harris-style bipod that retails for about $30 on Amazon (a 1/4 of the cost of a Harris). Its light-weight, aluminum construction features a low-profile mounting head that directly attaches to most AR-style octagonal M-Lok handguards.

The leg design is a copy of a Harris bipod with spring-loaded telescoping legs that deploy by swinging them down from and depressing the locking tab on the legs. Once deployed, the lower leg’s length can be adjusted by locking them onto segmented notches. The feet are rubberized pads, which are held in with rolled pins. I was not able to test if they were replaceable with spikes.

Until recently Harris did no have an M-Lok model but at Shot Show 2022, I was shown a prototype M-Lok bipod which appears similar. But unlike this CVLife bipod, the Harris prototype allows for cant adjustments and play . At the time of this video recording, the Harris M-Lok bipod has not yet been released, nor is it shown in their website. https://www.harrisbipods.com/bipods/

While this CVLife bipod is not as ruggedly constructed as a combat proven Harris, it should prove to be rugged enough to typical range shooters. It is best suited to light recoiling rifles such as .22LR and .223/5.56mm.

Testing on my Ruger Precision Remfire rifle, I was able to keep good groups at 100yrds (well, good enough groups using cheap Federal Champion .22LR cartridges). The bipod proved to be steady and rigged enough provide repeatable performance. Its long term durability will have to be tested over time.

CVLife sent me this bipod to test and evaluate. When comparing performance and price, this bipod is still good value.

Weight Sorting 22LR

There’s some old-school lore among bolt-action rimfire shooters that weight sorting bulk 22LR ammo is almost as good as buying Match Grade ammo. I put that theory to the test, partially out of curiosity and partly out of necessity. Since the COVID pandemic, Match Grade rimfire ammo has been impossible for me to find locally and what few boxes I could find were outrageously priced.

Match Grade rimfire ammo differs to cheap bulk ammo primarily in the quality control testing of the product. Many manufacturers do not make “practice” or “plinking’ grade ammo. Instead really only make Match ammo but based on the quality control testing of the batches, they reclassify and repackage the rejects lower grade varieties (Club, Target, Rifle, etc.). This quality control includes visually inspecting the uniformity of the cartridge as well as weighing them. Consistency in ballistic performance comes from consistency of the bullet cartridge.

I took the more mediocre 22LR ammo I had in stock, which was a loose box of Federal Champion “Blue Box”. Using a digital scale, I measure the weight in grains of each 22LR cartridge I would pull out of the box. I sorted the measured cartridges into groups: 49.8gr-51.2gr and under, 51.3-51.5gr, and 51.6gr-5.19gr. Any cartridges outside of these 3 batches was thrown in the “junk” pile; about 1 in 30 fell.

I took 50 rounds of the middle-weight batch (~51.4gr) to the range along with the new box of Federal Champion. Using my CZ-457 as the test bed, I set up a target downrange at 100yrds. I pasted up eight, 5/8″ sticker dots as my targets. I would fire 20 shots, 5 at shots at each of the 4 targets in each group.

The first group would be my weight-sorted batch. On second row of dots would use random bullets pulled from the Federal blue box. I chose to shoot the random batch 2nd to afford it the best opportunity possible. Compared to the Weight Sorted batch, the barrel would be well seasoned and I would have been warmed up from shooting the 1st batch.

Inspecting the target afterwards, my first impression was that there wasn’t a huge difference between the two rows. But after taking a photo and crunching the numbers using my phone’s Range Buddy app, the number told a different story. The Weight Sorted batch scored an average of 1.25 MOA whilst the Random Batch scored an average of 1.83 MOA. That 0.58 MOA difference that’s an almost 60% improvement!

But in the real world 0.6 MOA, hardly seems worth the time and effort to measure each 22LR cartridge. Certainly when shooting at a competition, every little bit helps. In one of my recent matches the difference between my 1st place win and 2nd place was only 3 points.

You can try it yourself to see how much a difference weight sorting is to you. You’ll need a precision digital scale that can measure to the nearest 0.01g . I used this one: https://amzn.to/3s8NG4j

Leupold Mark3HD 8-24×50

I bought my first Leupold a Mark 3HD 8-24×50 to pair with my new Ruger Precision Rimfire 22LR rifle. Its optical performance did not disappoint. In my camera testing and naked-eye observation it produced stunningly sharp and bright images with its HD glass.

Using the USAF-51 optical resolution chart, I could see resolution lines down to Group 0 which put this scope in the same league as some 60mm and 80mm spotting scopes! In glass performance, this is the sharpest and brightest scope I’ve tested in the sub $900 tier. Not surprisingly, only its big brother, the Mark 5 was able to resolve even smaller elements on the chart but that scope is four times the price.

While I had this on a 22LR, this scope is better suited for a high-power rifle. At 8x, it’s eye relief was well over 5″ behind the eye-piece at low power. This proved to be a challenge in filming as my phone/camera mount could not really be extended that far. At high-power the eye relief contracted slightly but the eye-box did quite profoundly; at 24x its eye-box was rather unforgiving.

It’s low, hunting profile turrets were a bit disappointing. The clicks were soft and muffled. But the tracking was dead-nuts accurate. The elevation turret had a precise and easy to use zero-stop and the windage was covered by a cap, hunting-style.

It has a 2nd focal plane Mil-Spec metal P5 TMR reticle. They way Leupold designed their Mk3, it uses the exact same reticle scrim plate as the lower power Mk3 but enlarged at a fixed 24x size. Because its a 2nd focal plane, the reticle size doesn’t change. Unfortunately, this also means the reticle appears overly thick at low power. This may be great for hunters who prefer a reticle that doesn’t get lost in their field of view. But a thick reticle is anathema to precision shooters because it obscures small targets and bullseyes.


Unfortunately this was a dealbreaker for me. While I love the glass clarity and Leupold’s reputation for reliability, the reticle made this a hard-pass for me. Regretfully, I returned it and will have to look for one of Leupold’s other models for my needs.

Feyachi LF58 Retro TLR-2 or Rip-Off?

Back in 2004 we were watching the Matt Damon in the first Bourne sequel, Tobey Mcguire in Spiderman 2, and looking at Streamlight’s newest pistol light with a built in laser, their TLR-2. One could easily mistake the Feyachi LF58 for a remake. While not a 100% copy of the TLR-s, the Feyachi LF58 is strikingly similar.

Feyachi sent me an LF58 to test and review. It came in a plain brown box containing the light, instruction pamphlet, pair of CR123A lithium batteries A set of batteries is included in the battery compartment of the light with protective plastic contact barriers which much first be removed to activate the light. The box also contained two Allen wrenches; one for the base mount and the smaller to adjust the laser.

The LF58 is the green laser variant, mated to a 200LM light. It mounts via an integrated Pictinny rail clamp and mates well with my Glock 17 postil. In my testing, I found the built in laser was very nearly aligned to the bore. Slight adjustments can be made with an included Allen wrench to achieve a 1:1 zero.

The controls are very much a copy of the Streamlight TLR-2 with toggle-posts in the rear battery compartment which can be manipulated with either the primary or secondary index fingers. The light as momentary and constant on settings. A dial near the bottom of the scope selects for light-light&laser-laser modes.

In my testing I found that the light output far exceeded the stated 200LM by Fayachi. My readings placed it closer to 400LM. This is only half the max output of a modern TLR-2 (~1000LM) but still plenty bright for most home defense situations.

I plan to conduct further testing to determine its long term durability and reliability. While it seems to sufficiently rugged for range use, I’m not yet convinced that it’s reliable enough for personal defense.

Panasonic HF100 Headphones

The HF100 is one of Panasonic’s most affordable wired headphones. They feature a clean modern design in a semi-open headset; the ear cups do not completely cover all of your ear. The ear cups do feature padding that provides a good sound isolating seal around your ear though some may find the squeeze uncomfortable over long periods of time.

They are a step up from their HT21 budget headsets but sound quality is very similar. They are well balanced for headphones under $30, though far from audiophile quality. Those looking for thumping bass will be disappointed. They are better than the free headphones issued on flights (unless you’re in Business class).

Unlike the HT21, these headphones also include an inline microphone and volume controls in the audio cord. The flat insulated wire cord feel somewhat silicone coated and ends in a standard 3.5mm TRRS jack. These lend themselves for use as inexpensive gaming or Zoom headsets, though they lack the heavy bass and venting for the former.

For the price and the microphone feature, these headphones are a good option for travel headsets or headsets you can send with your kids to school. They are inexpensive enough that you won’t have to cry about losing or breaking them. Though their lightweight construction does make me question their durability?

They come in a variety of colors (white, red, pink, black, and blue). I purchased these blue headsets from Amazon and they are also available from Best Buy, Walmart, and other retailers. Purchase through my Amazon Affiliate link to support my channel: https://amzn.to/3LmZoQr

Shot Show 2022: Ammo-Up

If you enjoy shooting at the end of a fun day at the range, you’ll be left with a smile on your face and a lot spent brass on the ground. Unless you’re shooting at some full-service indoor range, chances are you’re responsible for “policing” your brass; you need to pick up a broom and a dustbin and clean up after yourself.

Ammo-Up is a company that makes a very clever and effective tool that picks up almost all types of spent shell and collects them in easy to dump bins. This device is vaguely shaped like a push lawnmower. It has a roller with long polymer fingerlike bristles which grab the shells from the ground and a teeth above the brass bin combs the shells out of the bristles into its catch bin.

Cleaning up is as easy as rolling over the brass and Bobs-your-uncle, the brass it gone. The picker works on carpet, concrete, and even sand. But it doesn’t work on gravel (which get lodged in the bristles along with shells) nor does it work on .22 or smaller rimfire (the shells are too small).

We have a large sized unit at the Coyote Point Range that the Sheriff’s use for their 9mm and 5.56mm shells but us poor rimfire shooters have to contend with old school brooms and dustbins. I stopped by the Ammo-Up booth to see if they had come up with a solution or option for .22LR but alas, no.

Their units are sold online and are available on Amazon. https://amzn.to/3L0Zcpt

Hi-Lux Malcolm 20x

https://rumble.com/embed/vzh5ie/?pub=7xlsb Monetized

If you own an original, vintage, collectible rifle or a modern replica, it only makes sense that you’d want a scope to match its period aesthetics. Often times, a vintage scope, in good condition, can be as hard to find and as dear as the rifle you put it on. To serve this collector market, Leatherwood/Hi-Lux introduced their W.M. Malcolm line of target scopes.

Malcolm scopes utilize modern C&C construction methods, materials, along with modern optics and coatings. I saw their newest scopes at Shot Show 2022 but got a hands-on demonstration back home from my friend Mike at the Coyote Point Rifle and Pistol Club. He recently purchased a 20x Malcolm scope for a 1950’s vintage BSA Martini International Target 22LR.

This scope was a replica of Unertl scopes made from the 1930’s-2008. Rather than turrets that manipulate internal lenses, Unertl scopes use a unique mount, with turrets that move the entire scope tube within its brackets. While precise, its external mechanism is exposed to the elements and the environment; a design not known for ruggedness or durability when abused.

Despite the Unertl’s design quirks, it is able to retain zero on large caliber and magnum rifles. Legendary Marine Corps sniper Sgt. Hathcock utilized a Unertl scope on one of his sniper rifles. He was credited for 93 confirmed kills during the Vietnam War.

Looking through the scope, I was surprised at how sharp the image was. Looking at at the USAF Optical Resolution chart, at 100 yards, I was able to make out vertical and horizontal lines down to Element 1 of Group 0. This level of detail was comparable to a $2500 Leupold Mark 5, I recently reviewed.

Part of the reason for its optical performance was due to it being a fixed 20x power scope. Variable power scopes can have chromatic aberrations, darkening, or distorted image due to the additional lenses required to shift magnification. A fixed power scope does have limits to its field of view and versatility. But mounted to a long-distance target rifle and shooting 100 yrd. bullseye, a fixed power scope isnt’ at a disadvantage.

Annoyingly the original edit of the video was erroneously rejected by YouTube’s staff reviewers, categorizing its content as “Firearms Modification.” But by their own definition: “Modifications” refer to anything that interferes, enhances or changes the internal functioning of the product, as well as hair triggers, bump stocks, and explosive/incendiary ammunition, or other attachments such as thermal/infrared sights or large capacity magazines. Anyone with basic firearms understanding would see that the video does not depict any internal modifications of any sort, nor are any of the other cited issues presented. I have had to re-upload a lengthy explanation section to educated YouTube staff.
