Saturday Movies: New Athlon Rangecraft Radar Chronograph

Today’s Movie Showcase features video reviews of the new Athlon Rangecraft radar chrono that offers exceptional performance for the price. At $399.99 MSRP, the new-for-2025 Athlon Rangecraft Velocity Pro Chronograph is about $200 cheaper than the popular Garmin Xero C1 Pro Chrono, which costs $599.99. So far, most tests show that this compact Athlon Chrono works very well and its Doppler Radar system is accurate. Velocities may be a few FPS faster that with a Garmin, but the ES/SD values are very close. If you are in the market for a new chronograph, definitely watch these videos. And take note — right now, for the Independence Day weekend, Brownells is offering a 15% off discount that can reduce the price of a new Athlon Chrono to $339.99 (use Code USA15 at checkout). NOTE — this deal may expire very soon!

Ultimate Reloader Test of Athlon Rangecraft Chronograph

Athlon’s NEW Rangecraft Velocity PRO Doppler Radar Chronograph is impressive, and it is a genuine rival to the popular Garmin. In this video Gavin Gear of UltimateReloader.com walks through the features and specs, and the hardware. Then the video covers the testing process and shows the workflow with this high-value, compact chrono.

Athlon Rangecraft Velocity Pro Chronograph, $399.99

The new Athlon Rangecraft Velocity Pro Radar Chronograph is an impressive and very affordable compact chrono, selling for $399.99 at most vendors. This employs Doppler radar allowing ultra-accurate velocity readings. Since the unit isn’t triggered by a muzzle blast, it can work with suppressors, muzzle brakes, and other muzzle devices. The Rangecraft Vel Pro reads velocities between 65 FPS and 5000 FPS. So far field tests have shown that the Athlon Rangecraft chrono is reliable and picks up all shots fired with all types of rifles and pistols (even airguns). However the listed velocities may be a few FPS different than a Magnetospeed or Labradar. Athlon also has a good Ballistics Lite App that works with this chrono — see video at 21:45 time-mark. The unit includes a compact tripod.

Athlon Rangecraft vs. Garmin Xero C1 — Chrono Comparison Test

Here are two short videos that show side-by-side comparison tests of the new Athlon Chrono with its main comparison, the Garmin. These vertical-format videos are easy to watch with your cell phone. The tester found the Athlon “had a faster calculation and refresh rate” than the Garmin. The Athlon also has “slightly larger display screen” and a two additional buttons for somewhat “easier ergonomics”. In this test the Athlon velocity readings were about 4 FPS faster than the Garmin.

Comparison Test: Athlon vs. Garmin vs. Magnetospeed

This 27-minute review by Full Circle Reloading starts with unboxing and set-up of the new Athlon Chrono. Then the video compares the features of the Athlon Rangecraft Chrono with the Garmin Xero C1 Pro chrono. Then, using a rifle fitted with a Magnetospeed barrel-mounted chrono, the host compares results from all three chronographs: Athlon, Garmin, and Magnetospeed. The results are very interesting. This is a “must-watch” video if you are considering upgrading from a Magnetospeed to a radar chronograph.

Field Test with 6mm ARC Rifle and 5.56 PSA Jackl and 9mm Pistol

This field test features two AR-type firearms (6mm ARC long barrel and 5.56 NATO 10.5″ barrel PSA Jakl) and a 9mm Springfield Echelon pistol. The tester says the fact that the Athlon is $200 less than the Garmin is “fantastic”. His Athlon Rangecraft Velocity Pro Doppler Radar unit performed very well with all the guns tested, delivering reliable velocity read-outs “without the fuss of barrel attachments or bulky setups”.

Athlon Chrono Integration with Athlon Ballistics Lite App

This 12.5-minute video shows how the Athlon Ballistics Lite App works with the new Athlon Rangemaster Chrono. The App “talks” to the unit via Bluetooth and so can then record the details of each shot including speed, deviation from average, Extreme Spread (ES), Standard Deviation (SD), and kinetic energy (after you’ve entered bullet weight). This information can be scrolled shot-by-shot as well as viewed in tables. You can create separate record for different firearms and different bullet types.

Brownells Athlon Chrono Feature and 15% Off Discount Code

As part of its July 4th weekend promotion, Brownells is offering 15% Off orders of $200 or more. To get this 15% discount, use Promo Code USA15 during checkout. And yes you can get a 15% discount on the popular new Athlon Rangecraft Radar Chronograph, with a $339.99 price after 15% discount. NOTE: This 15% discount may expire very soon.

Good Guidance for Efficient and Safe Case Priming

Primer Forster Co-ax priming tool
The anvil is the tripod-shaped thin metal piece protruding above the bottom of the primer cup. Getting the primer sitting fully flush on the bottom of the case primer pocket, without crunching it too much, requires some keen feel for the progress of primer seating.

Sadly, Glen Zediker passed away in October 2020. However, his insights live on through his written works. This feature is based on Glen’s popular reloading books and his articles for the Midsouth Blog.

In two informative Midsouth Blog articles, Glen Zediker offered helpful advice on priming. First he examines what happens to the primer itself as it is seated in the cup. Glen explains why some “crush” is important, and why you never want to leave a high primer. Glen also reviews a variety of priming tools, including his favorite — the Forster Co-Ax Bench Primer Seater. Then he offers some key safety tips. Glen provides some “rock-solid” advice about the priming operation. These reloading tips came from Glen Zediker’s popular book, Top-Grade Ammo.

Priming Precision vs. Speed
Glen writes: “The better priming tools have less leverage. That is so we can feel the progress of that relatively very small span of depth between start and finish. There is also a balance between precision and speed in tool choices, as there so often is.”

Benchtop Priming Tools — The Forster Co-Ax
Glen thinks that the best choice among priming options, considering both “feel” and productivity, may be the benchtop stand-alone priming stations: “They are faster than hand tools, and can be had with more or less leverage engineered into them. I like the one shown below the best because its feeding is reliable and its feel is more than good enough to do a ‘perfect’ primer seat. It’s the best balance I’ve found between speed and precision.”

Load Tuning and Primers
Glen cautions that you should always reduce your load when you switch to a new, not-yet-tested primer type: “The primer is, in my experience, the greatest variable that can change the performance of a load combination, which is mostly to say ‘pressure’. Never (never ever) switch primer brands without backing off the propellant charge and proving to yourself how far to take it back up, or to even back it off more. I back off one full grain of propellant [when I] try a different primer brand.”

Priming Safety Tips by Zediker

1. Get a good primer “flip” tray for use in filling the feeding magazine tubes associated with some systems. Make double-damn sure each primer is fed right side up (or down, depending on your perspective). A common cause of unintentional detonation is attempting to overfill a stuffed feeding tube magazine, so count and watch your progress.

2. Don’t attempt to seat a high primer more deeply on a finished round. The pressure needed to overcome the inertia to re-initiate movement may be enough to detonate it.

3. Don’t punch out a live primer! That can result in an impressive fright. To kill a primer, squirt or spray a little light oil into its open end. That renders the compound inert.

4. Keep the priming tool cup clean. That’s the little piece that the primer sits down into. Any little shard of brass can become a firing pin! It’s happened!

These Tips on Priming come from Glen’s Zediker’s excellent Top-Grade Ammo book, sadly now out of print. We also recommend Glen’s New Competitive AR-15: The Ultimate Technical Guide, which includes good general information on AR components and reloading.
