Henderson Case Trimmer Reviewed — Fast and VERY Repeatable

Henderson case timer powered Gen 3 brass trimming machine

Our friend and colleague F-Class John tests some of the finest reloading and shooting equipment you can buy. Recently he added the impressive Henderson Gen 3 Powered Trimmer to his inventory of tools. John is now a Henderson fan. He likes the speed, precision, and repeatability of the $779.00 Henderson machine, which trims-to-length and chamfers the case mouth all in one pass. Unlike some other trimming tools, the Henderson indexes off the overall case length NOT the shoulder. John found this worked just fine for his .284 Winchester brass, which has all been full-length sized prior to trimming.

John liked the precision of the Henderson trimmer and the overall design of the machine, which offers good ergonomics and very precise alignment of the cases. Cycling is smooth and positive, as you can see from the videos. Fit over the pilot was fine for John’s .284 Win brass, but he notes that other users may need to expand their case necks appropriately to fit their pilot.

Watch the video to see the Henderson trimmer in action. The dual, parallel horizontal support shafts provide precise alignment of the case as it moves inward toward the cutter blade. The Taper-Lock cutter provides a 14-degree inside chamfer and 30-degree outside chamfer. The trimming process is very consistent case after case, and the Henderson’s design captures brass shavings effectively.

Testing Trim Length Consistency — Henderson Shows Superb Repeatability
John did a separate quick test to demonstrate the trim length consistency of the Henderson unit. Measuring with digital calipers, John found that he could easily hold case overall trim lengths within .001″ (one-thousandth). The consistency was excellent even when trimming cases very quickly. When trimming .003″ off his cases, John said the Henderson showed superb repeatability. Henderson promises the trimmer “will repeat to within 0.002″ with same brand brass”, and John was able to hold 0.001″ length consistency.

Another Henderson owner posted: “I love mine. I like [the] consistent trim length with the positive stop. [Doing] the trim, chamfer, and debur all in one step sure makes the process nice and easy! I also immediately noticed the problem with the pilot on the cutting head with my sized cases. I just polished the pilots on my cutting heads with some fine grit sand paper a little at a time till I got it perfect for my preferred neck tension setting! I’m very pleased with my purchase of the Henderson precision trimmer.”

Henderson Power Trimmer vs. Giraud Power Trimmer

Henderson case timer powered Gen 3 brass trimming machineAfter he tested his new Henderson trimmer, F-Class John compared the pros and cons of the Henderson vs. his other high-volume power trimmer, a Giraud. He likes both machines, but now favors the Henderson for trimming his .284 Winchester match brass. He found that his ES/SD dropped a bit for brass trimmed with the Henderson vs. brass trimmed with the Giraud. With the Henderson-trimmed brass, John achieved an ES of 15 fps for 49 shots. That’s mighty impressive (see photo at right).

But the Giraud does have it’s advantages. It can work with calibers above .338, and it is very fast. One viewer of this video commented: “The Giraud is insanely fast if you aren’t only loading insane precision ammo. I borrowed one when I first started reloading and immediately ordered one. I’ve trimmed somewhere between 40-50k .223 cases. You can just rip through them while watching TV or listening to a podcast. It trims to length consistently less than +/-.001 all day.” The Giraud also indexes off the shoulder while the Henderson trims based on Cartridge Overall Length (OAL).

Hornady Ballistics Calculator

Hornady Ballistics CalculatorNeed a simple, easy-to-use drop chart for your rifle? Something you can tape right to the buttstock? Then check out Hornady’s handy Online Ballistics Calculator. This user-friendly calculator will compute your drops accurately, and output a handy “Cheat Sheet” you can print and attach to your rifle.

Here’s how it works. From the Ballistics Calculator Page, simply input G1 or G7 BC values, muzzle velocity, bullet weight, zero range, and a few other variables.

Click “Calculate” to view the full chart (shown below). Then click “View Cheatsheet” and the simpler, 4-line Drop Chart (shown above) appears. Click “Print” and you’re done!

The online ballistics caculator is easy to use. You can select the basic version, or an advanced version with more data fields for environmental variables (altitude, temperature, air pressure, and humidity). You can also get wind drift numbers by inputing wind speed and wind angle.

Conveniently, on the trajectory output, come-ups are listed in both MOA and Mils — so this will work with either MOA clicks or Mil-based clicks.

Nosler Reloading Guide 9 Has Data for 101 Cartridge Types

Nosler reloading guide number 9 9th edition handbook book load data manual

Nosler now offers the Nosler Reloading Guide #9, the latest in a respected series of hardback Nosler load manuals. This 800-page guide covers 101 cartridge types. New in this edition you’ll find the popular 6mm Creedmoor, 6mm XC, 6.5 PRC, and 7.62×39, along with 20 Nosler, 22 Nosler, 24 Nosler, 27 Nosler and 33 Nosler. This new guide draws from thousands of hours in the Nosler Ballistic Lab, along with the experience of many respected experts.

The book is available now for $27.99 at Grafs.com. In addition, much of the book’s latest load data is available for free on the Nosler.com online LOAD DATA Center. But to get ALL the data, PLUS the technical articles, you’ll need to buy the book.

The Nosler Reloading Guide 9 Reloading Manual provides load data for 101 rifle and handgun cartridges with hundreds of new powder additions. A comprehensive data set for today’s reloader, this manual is current with every bullet that Nosler offers through 2020 from 17 caliber up to 458 caliber in the rifle section and 9mm up to 45 caliber in the handgun section. Nine new cartridges were added to this manual. These include: 20 Nosler, 22 Nosler, 24 Nosler, 6mm Creedmoor, 6mm XC, 6.5 PRC, 27 Nosler, 7.62×39 and 33 Nosler. Also new for the Nosler Reloading Guide #9 are cartridge introductions written by veteran outdoor writers and industry tech experts. The 800-page book also has helpful “how-to” sections such as “Getting Ready to Reload”.

Q. Why Buy a Book when Load Data is Available Online from Powder Makers?

There are good, solid reasons to buy print-format loading guides produced by bullet-makers. If you go to the Hodgdon online Reloading Data Center you’ll only find loads with Hodgdon, IMR, and Winchester powders — the key brands they sell. In a book such as this Nosler #9 or the Sierra Reloading Manual, you will find loads with a much wider selection of powders including Vihtavuori, Alliant, Accurate, Norma, Ramshot, and other brands. You won’t find a Reloder 16 or VV N140 load on Hodgdon’s website.

In addition, it is handy to have loads in a print edition which is easy to access on your load bench. You don’t need a computer or an internet connection. And using a book is often faster than a web interface when quickly scanning through a variety of bullet choices for a cartridge.

Along with the Nosler #9 Manual, here are four other recommended Reloading Manuals:
