Trim, Chamfer, and Deburr Brass Cases with Giraud Tri-Way Tool

Giraud Tri Way Trimmer Case Cutter tool
Close-up of the Tri-Way Trimmer with clear plastic chip guard removed.

Giraud Tool offers a case trimmer/chamferer device that works with a power drill (or other power source). Giraud’s patented Tri-Way Trimmer is a self-contained unit powered by your drill or motor. Using a sharp carbide blade it will trim your cases to length, deburr, and cut both inside and outside chamfers — all in one pass. That’s pretty impressive for a $110.00 tool that fits in the palm of your hand.

Giraud Tri Way Trimmer Case Cutter tool

Product Features
1. Fully adjustable for cartridge length (and depth of chamfer).
2. Carbide blade cuts a 15° inside case mouth chamfer and 45° outside chamfer.
3. Case holder supported by sealed ball bearing raceway.
4. Tool includes removable, transparent plastic chip guard.
5. Tool can work in any orientation (vertical, horizontal, or any angle).

The Giraud Tri-Way Trimmer is designed to be powered by a portable hand drill, drill press, or other dedicated rotating power source. The tool indexes off the shoulder of your cases, but the blade adjusts so that cartridge overall length (COAL) can be controlled with precision. Constructed out of 6061-T6 aluminum and 303 stainless steel, the Tri Way tool should last a lifetime. Note: This tool is not universal. The Tri Way is dedicated to a single cartridge and “related” cartridges with similar body dimensions. Thus you need a specific tool for each cartridge family. For example, the .308 Win tool will also trim .243 Win, .260 Rem, and 7mm-08.

Cartridge Sizes Available for Giraud Tri Way Trimmer:
.223 Remington (Also trims .17 Remington, .204 Ruger, .222 Remington, .222 Remington Magnum)
7.62 x 39mm (Russian)
.300 Blackout (Also trims .17 Rem Fireball, .20 Vartarg, .221 Fireball)
.308 Winchester (Also trims .243 Winchester, .260 Remington, 7mm-08)
.30-06 Springfield (Also trims .25-06, .270 Winchester, .280 Remington)
.300 Winchester Mag (Also trims ​Also trims .264 Winchester Magnum, 7mm Remington Magnum, .308 Norma Magnum)

Die Shims for FL Sizing Dies Give Precise Control of Bump

Sinclair Die Shims

When your cases become hard to extract, or you feel a stiff bolt lift when removing a cartridge, it’s probably time to full-length size your cases, and “bump” the shoulder back. We generally recommend bumping shoulders each time you reload, after the initial fire-forming. Benchrest and F-Class benchrest shooters, running relatively high pressures, typically full-length size every load cycle, bumping the shoulder .001-.003″. High Power shooters with gas guns generally full-length size every time, and may need to bump the shoulders .003″ or more to ensure reliable feeding and extraction.

Use Shims for Precise Control of Shoulder Bump
Some shooters like to set the “default” position for their full-length die to have an “ample” .003″ or .004″ shoulder bump. When they need less bump, a simple way to reduce the amount of shoulder movement is to use precision shims in .001″ (one-thousandth) increments.

Here are reports from Forum members who use the shims:

“Great product. I have my die lock ring(s) adjusted for the shortest headspace length on my multiple chambers 6BRs and 6PPCs. When needing a longer headspace, I just refer to my notes and add the appropriate shim under the lock ring. Keep it simple.” — F.D. Shuster

Mats Johansson writes: “I’ve been using [shims] since Skip Otto (of BR fame) came out with them. I set up my dies with the .006″ shim, giving me the option of bumping the shoulder a bit more when the brass gets old and hardens while still having room to adjust up for zero headspace, should I have missed the original setup by a thou or two. Hunting rounds can easily be bumped an extra .002-.003″ for positive, no-crush feeding. Being a safety-oriented cheapskate, I couldn’t live without them — they let me reload my cases a gazillion times without dangerous web-stretching. Shims are a must-have, as simple as that.” — Mats Johansson

Sinclair Die Shim Kit — Seven Shims for $14.99

Sinclair Die Shims

Sinclair Int’l (through Brownells) offers a seven-piece set of Sizing Die Shims that let you adjust the height of your die (and thereby the amount of bump and sizing) in precise .001″ increments. Sinclair explains: “Some handloaders will set their die up to achieve maximum sizing and then progressively use Sinclair Die Shims between the lock ring and the press head to move the die away from the shellholder. Doing this allows you to leave the lock ring in the same position. These shims are available in increments of .001″ and work very well.”

Seven Shims from .003″ to .010″
Sinclair’s $14.99 Die Shim Kit (item 22400) includes seven shims in thicknesses of .003, .004, .005, .006, .007, .008, and .010. For ease of use, shim thickness is indicated by the number of notches cut in the outer edge of each shim. Even without looking you can “count” the notches by feel.

Inside Look at Nosler Factory Plus Nosler Load Data Resources

Nosler bullets nosler.com website ecommerce

Ever wanted to see how Nosler bullets and cartridges are made? Here’s your opportunity. The Rocky Mountain Elk Foundation (RMEF) has produced a video (“Quality First”) that offers a behind-the-scenes look inside Nosler’s Oregon factory that produces bullets, brass, and ammunition.

Video Showcases Nosler Production Facility and Ballistics Lab

RMEF representatives were provided with unprecedented access into Nosler’s famously-guarded manufacturing plant to show the technology used by Nosler to produce bullets and ammunition. The “Quality First” video showcases Nosler’s complex production processes that include technologically advanced machinery, and stringent quality control measures.

Nosler bullets nosler.com website ecommerce

After the intro, this video illustrates Nosler’s bullet construction techniques with a cool animation sequence. The video then showcases the Nosler ballistics lab, inspection room, and packaging line.

The “Quality First” video starts with the history of the company, tracking Nosler’s development from the 1940s. Then the video shows the bullet construction techniques followed by a ‘walk-though’ in the factory, showing the sophisticated machinery used to make bullets, brass, and ammunition. “‘Quality First’ isn’t just a saying that’s printed on our factory walls, it’s the guiding principle that affects every decision we make” says Mason Payer, Senior Marketing Manager at Nosler.

Information Resources — Load Data and Nosler Blog
The enhanced Nosler website also features comprehensive LOAD DATA, plus informative content in the Nosler Blog. The Load Data page works well on smartphones. Go to the Load Data Index Page, then simply scroll down to a caliber. Then select your cartridge type and bullet weight(s). The rifle listings are quite comprehensive, covering .17 caliber up to .458 caliber. Here are examples of Nosler load data for the 6mm Creedmoor with popular 105-107gr bullets, along with the .284 Winchester with 175gr bullets.

Look Inside Ammo — Cutaway Cartridge Views

sliced cutaway ammo ammunition FOG diagram

Here’s something you don’t see every day — the inside of loaded cartridges, sliced halfway through. This lets you see how bullet core, jacket, cartridge case, powder, and primer all fit together. Give credit to the folks at FOG Ammunition for creating this interesting series of cut-through ammo images. We show four cartridges here: the .308 Winchester, 9mm Luger, 300 BLK, and .50 BMG. You’ll find two more (the .223 Remington and .45 ACP) at www.FogAmmo.com.

sliced cutaway ammo ammunition FOG diagram

This .308 Winchester model took on a different approach by only cutting the brass case and displaying the full bullet, primer and powder load. A spec amount of powder was used to create the model powder form. An estimated 10% volume was added during the forming process, along with an undetermined amount of air pockets.

This bisection is a 9mm Luger Jacketed Hollow Point round with flake powder held together with super glue. After this self-defense round was cut by a trained professional the round was polished by hand. This might look like stick powder, but those are in fact flakes stacked up in cross-section. Designed in 1901 by Georg Luger, this popular cartridge is used by civilians, military, and law enforcement.

sliced cutaway ammo ammunition FOG diagram

For this model of the .300 AAC Blackout (aka 300 BLK), a Dremel tool was used to create a pie cut within the bullet and brass case. A measured amount of power, roughly 65% of spec charge, was placed inside the case with super glue. This cartridge was originally optimized for subsonic use with a suppressor, so the amount of powder used is small relative to the nominal case capacity. That leaves more room for the relatively large .30-caliber bullet.

sliced cutaway ammo ammunition FOG diagram

Last but definitely not least is the .50 Caliber BMG round (aka .50 Browning Machine Gun). Famed for its wartime use in the M2 Machine gun, the .50 BMG round is also used in civilian Long Range competitions. A typical .50 BMG cartridge holds over 225 grains of powder. That’s almost ten times the amount in a 5.56×45 NATO Round! To demonstrate the size of the .50 BMG, check out that .223 Rem for comparison.

Great Loading Gear Transporter Made from Horse Grooming Box

Range carry loading reloader box case transport horse equine grooming case box

Do you often load at the range? Or maybe you need to transport loading gear when you travel in your RV. Well here is a smart transport option — a metal box that holds tools, dies, arbor press, case-trimmer, even a ChargeMaster.

Some guys have built their own loading tool-boxes from wood. Other may stuff gear in a couple of plastic range boxes. But clever Chris Covell came up with an even better solution. Chris sourced a handsome, sturdy metal Horse Grooming Box from eBay. Chris reports the multi-feature metal box “works perfectly for reloading. My ChargeMaster is now out of the wind.”

Range carry loading reloader box case transport horse equine grooming case boxBullets, Trickler, and Priming Tool on Top
On top, below the hinged metal lid, is a large compartment that holds Covell’s funnels, scales, priming tool, trickler and other vital gear (photo on right). This top compartment is deep enough to handle wide-mouth funnels with no problem.

Slide-Out Drawer with Dividers
Below the top level is a handy sliding drawer with multiple dividers. This is perfect for holding Covell’s inline seating dies, case-neck deburring and chamfering tools, among many other smaller bits and pieces.

In the bottom of the Horse Grooming box is a large compartment that holds bigger gear. In the bottom section, Covell places his RCBS Chargemaster Lite, along with a case-trimming tool, an arbor press, and various other bulky tools. Check it out:

Range carry loading reloader box case transport horse equine grooming case box

Folks who load at the range need to bring a lot of gear — reloading presses, powder dispensers, scales, funnels, sizing/seating dies, brass prep tools and more. And there may be other important items to transport — such as ammo caddies, LabRadar mounts, over-size rest feet, and even barrel fans. With this metal box you can easily organize (and protect) al that gear. This box was sourced affordably via eBay.

Chris Covell’s Range Box was featured on the Benchrest Shooting and Gunsmithing Private Group Facebook Page. You may want to sign up for this Group — with membership you can access a wealth of information for accuracy-oriented shooters.

How Altitude Affects Ballistics — Hunters Take Note

altitude ballistics zeiss LRP S5 318-50 FFP scope
Photo shows the new ZEISS LRP S5 318-50 first focal plane (FFP) scope.

“A bullet launched at a higher altitude is able to fly slightly farther (in the thinner air) for every increment of downward movement. Effectively, the bullet behaves as if it has a higher ballistic coefficient.”

It’s hunting season, and we have a friend who wants to go the high country of Colorado to pursue elk. He recently zeroed his rifle in California, at a range just a few hundred feet Above Mean Sea Level (AMSL). He wondered if the higher altitude in Colorado could alter his ballistics. The answer is a definite yes. However the good news is that free ballistics calculators can help you plot reliable drop charts for various shooting locations, high or low.

Suunto AltimeterThe question has been posed: “What effect does altitude have on the flight of a bullet?” The simplistic answer is that, at higher altitudes, the air is thinner (lower density), so there is less drag on the bullet. This means that the amount of bullet drop is less at any given flight distance from the muzzle. Since the force of gravity is essentially constant on the earth’s surface (for practical purposes), the bullet’s downward acceleration doesn’t change, but a bullet launched at a higher altitude is able to fly slightly farther (in the thinner air) for every increment of downward movement. Effectively, at higher altitudes, the bullet behaves as if it has a higher ballistic coefficient.

Forum member Milanuk explains that the key factor is not altitude, but rather air pressure. Milanuk writes:

“In basic terms, as your altitude increases, the density of the air the bullet must travel through decreases, thereby reducing the drag on the bullet. Generally, the higher the altitude, the less the bullet will drop. For example, I shoot at a couple ranges here in the Pacific Northwest. Both are at 1000′ AMSL (Above Mean Sea Level) or less. I’ll need about 29-30 MOA to get from 100 yards to 1000 yards with a Berger 155gr VLD at 2960 fps. By contrast, in Raton, NM, located at 6600′ AMSL, I’ll only need about 24-25 MOA to do the same. That’s a significant difference.

Note that it is the barometric pressure that really matters, not simply the nominal altitude. The barometric pressure will indicate the reduced pressure from a higher altitude, but it will also show you the pressure changes as a front moves in, etc. which can play havoc w/ your calculated come-ups. Most altimeters are simply barometers that read in feet instead of inches of mercury.”

As Milanuk states, it is NOT altitude per se, but the LOCAL barometric pressure (sometimes called “station pressure”) that is key. The two atmospheric conditions that most effect bullet flight are air temperature, and barometric pressure. Normally, humidity has a negligible effect. It’s important to remember that the barometric pressure reported on the radio (or internet) may be stated as a sea level equivalency. So in Denver (at 6,000 feet AMSL), if the local pressure is 24″, the radio will report the barometric pressure to be 30″. If you do high altitude shooting at long range, bring along a Kestrel, or remember to mentally correct the radio station’s pressure, by 1″ per 1,000 feet.

Trajectory of Bullet fired at Sea Level

Trajectory of Bullet fired at 20,000 feet

You can do your own experimental calculations using JBM Online Ballistics (free to use). Here is an extreme example, with two printouts (generated with Point Blank software), one showing bullet trajectory at sea level (0′ altitude) and one at 20,000 feet. For demonstration sake, we assigned a low 0.2 BC to the bullet, with a velocity of 3000 fps.

To learn more about all aspects of Exterior Ballistics, Hornady has a useful discussion of External Ballistics including the effects of altitude and temperature. To dig deeper, Sierra Bullets has a comprehensive Exterior Ballistics Resource Page with multiple sections from the Sierra Manual (4th and 5th Editions), including:

Section 3.0: Exterior Ballistic Effects on Bullet Flight
Section 3.1: Effects of Altitude and Atmospheric Conditions
Section 3.2: Effects of Wind
Section 3.3: Effects of Shooting Uphill or Downhill

Example from Section 3.0: “When a bullet flies through the air, two types of forces act on the bullet to determine its path (trajectory) through the air. The first is gravitational force; the other is aerodynamics. Several kinds of aerodynamic forces act on a bullet: drag, lift, side forces, Magnus force, spin damping force, pitch damping force, and Magnus cross force. The most important of these aerodynamic forces is drag. All the others are very small in comparison when the bullet is spin-stabilized.”

USA’s Chris Simmons Wins Rimfire Precision World Championship

Lapua Chis Simmons usa italy international precision rifle federation world championship

Chris Simmons Wins International Precision Rifle Federation PRS World Championships
Lapua congratulates Team USA’s Chris Simmons on winning the first-ever International Precision Rifle Federation Precision Rimfire World Championships. This highly anticipated match took place August 28 through September 3 at the Piancardato Tiro A Volo range in Collazzone, Italy. Chris was shooting a Vudoo rifle with Lapua X-Act .22 LR rimfire ammunition. Simmons posted an Aggregate score of 165.00 points with a time of 1480.45. The first four finishers were also from the USA. CLICK HERE to see hundreds of photos from the event.

Lapua X-ACT Chis Simmons usa italy international precision rifle federation world championship

The International Precision Rifle Federation (IPRF) World Championships drew top shooters from 23 nations. The three-day event had competitors tackle a challenging course of fire at different distances, shooting from both supported and unsupported obstacles, with long-range shots, and moving targets, all within tight time constraints.

Lapua Chis Simmons usa italy international precision rifle federation world championship

Simmons, no stranger to the winner’s circle, was part of a two-year selection process to represent the United States at the inaugural IPRF event. Over the past nine months, Simmons took his training to another level, getting up before daylight to hit the range. He also spent many evenings after work shooting 10-12 different positions in a 90-second timeframe, firing hundreds of rounds daily.

Lapua Chis Simmons usa italy international precision rifle federation world championship
Match was conducted in a beautiful hillside location in Collazone, Italy.

After surviving tricky wind conditions and bad wind calls, Simmons found himself in second place prior to going into the last two stages. He then performed great in the final two stages, taking the overall win: “Paul Dallin and I ended up tied and it came down to the fastest aggregate time of all the stages,” commented Simmons. “I won the World Championship by 23 seconds in 2023! Paul is a hell of a shooter and competitors and was tough to beat. Congratulations to him on his second-place finish!”
