A unique, comprehensive Cartridge Comparison Guide is now available as both a spiral-bound book and as an online database. The Cartridge Comparision Guide is the product of many years of labor by Andrew Chamberlain, a Utah-based hunter. Andrew says his Guide “compares every factory available cartridge from the 17 calibers up to the 50 caliber cartridges”. (Sorry, most wildcat cartridges are not covered.) Chamberlain’s Guide also compiles cartridge data from major ammunition manufacturers such as Barnes, Federal, Hornady, Norma, Nosler, Remington, Sierra, Swift, Weatherby, and Winchester. It shows the optimal velocity achieved for each bullet weight and calculates bullet energy, recoil, and powder efficiency.
Both print and web versions of the Cartridge Comparison Guide provide data for thousands of cartridge/bullet/velocity combos. Charts provide cartridge ballistics including downrange energy. The Cartridge Comparison Guide offers a firearms lexicon, plus Appendices covering Cartridge Selection for Game Animals, Bullet Selection/Design, Bullet Expansion, Wound Channel Characteristics and more.
Book Costs $24.99 — Online Access is $10.00 with FREE Trial
The Cartridge Comparison Guide book version costs $23.99 plus shipping and tax. Accessing the web-based version requires a $10.00 subscription, but Chamberlain offers a 2-Day free online trial membership. A portion of the proceeds of book purchases go to support Paralyzed Veterans of America. CLICK HERE to order the book, subscribe to the online service, or sign up for the free trial.
Great Resource for Hunters
One of Chamberlain’s main goals in creating the Cartridge Comparison Guide was to help hunters select the “right cartridge for the job.” According to Chamberlain: “This started as a personal project to gather information on the more popular cartridges commonly used for hunting. I began comparing cartridge performance, versatility, bullet selection, powder efficiency, recoil generation vs. energy produced, standing ballistic data for different environments, etc.” Chamberlain adds: “I wanted to find the best all-around performing cartridge and rifle that a guy on a budget could shoot.”

Bullet Proof Samples now offers 12-count packs of big-name bullets. This lets you try out many different bullet types without forking out big bucks for larger 50-ct or 100-ct boxes. Currently, Bullet Proof Samples offers projectiles from Barnes, Berger Bullets, and Nosler. The sample packs range in price from $5.49 (for 22-cal varmint bullets) to $15.99 (for a .30-Cal Barnes LRX). The Berger Bullets sample packs run $6.49 to $10.49, with the larger 7mm and 30-cal bullets at the upper end of the range. On a per-bullet cost basis, it’s still much cheaper to purchase a “normal” 100-ct box, but the sample packs let you “test before you invest.”
Berger’s Michelle Gallagher tells us: “We receive frequent feedback from shooters who are looking for bullets in small pack quantities so that they can test different bullets without the expense of buying full boxes. We’re pleased to be associated with the launch of Bullet Proof Samples. This is a new company who has done an exceptional job of addressing that concern. Bullets are packaged in blister packs, so they can be clearly seen. Each pack contains 12 bullets. They will be offering Nosler, Barnes and Berger in a variety of weights and calibers.
This effort will be featured in an upcoming issue of American Rifleman and will launch officially this week. Bullet Proof Samples is not a Berger Bullets LLC company, but we are supportive of their efforts and believe that they will be addressing a need in the shooting community that is presently unavailable.”

When Hornady (and CCI) developed the 17 HMR cartridge, they really hit a homerun. And the rifle manufacturers quickly marketed some nice rifles to chamber this 17-cal rimfire round. But unlike .22 LR rifles which, typically, require very little cleaning, 17 HMRs demand frequent bore cleaning to maintain good accuracy. That’s because 17 HMRs shoot copper-jacketed bullets at 2550 fps velocities.
17-Cal Bore Guides — The Challenge
The problem is, it’s hard to find a well-designed, quality bore guide for 17-caliber rimfire rifles. With many 17 HMR (and 17 Mach 2) rifles, you encounter mechanical interference when you try to use a standard bore guide to protect the delicate chamber edge and the bottle neck area of the chamber. A fixed ejector is in the way. On many 17 HMR rifles, this little “shark fin” ejector is right in line with the chamber and is fixed — it doesn’t retract. Therefore the kind of bore guide you might use for centerfire rifles won’t work in 17 HMRs — it will hang up on the ejector.
Polymer bore guides exist for this type of action, but they are typically open-bottom designs that do not enter and seal the chamber. These open-bottom designs don’t protect the delicate chamber edge or the bottleneck area of the chamber, and they also allow some seepage of solvents out of the chamber. That’s why Roy Bertalotto created his RVB Precision Bore Guide for 17 HMR rifles. The 7075 aluminum tube on his Bore Guide is thin enough to pass by the ejector, yet it is extremely rigid. (Photos below.)
Roy explains: “My bore guide is made of 7075 anodized aluminum tubing, which is totally unaffected by any type of cleaning solution. One end is swagged down to fit completely into the chamber of a 17 HMR rifle. This guides your cleaning rod perfectly to the bore without touching the chamber walls or front edge of the chamber. The tight fit of the bore guide in the chamber also stops cleaning solvents from getting into the action, magazine, and trigger housing.” (Editor: Solvent seepage can do damage. We had a 17 Mach 2 rifle that rusted internally because solvents leaked past an open-bottom bore guide.)
Using the RVB 17 HMR Guide – Once the bore guide is in place, slide the supplied aluminum bushing over the tube, and gently push the bushing into the rear of the action. This centers the guide rod in the action to keep the guide rod tube aligned. Once the guide rod and bushing are in place, you can use a 17-caliber cleaning rod* with patches and/or brushes to clean the barrel. Use the rod normally, but make sure your patches are quite small and don’t apply too much pressure as these small-diameter rods can kink if you try to force over-size patches down the bore.
The RVB Precision 17 HMR Bore Guide costs $19.95 plus $5.00 shipping. To order, email Roy Bertalotto via rvb100 [at] comcast.net. Roy will then send you shipping/payment details.
* NOTE: You really do need a dedicated .17-cal cleaning rod for this job. Most other rods are too fat to pass through the barrel. Dewey Mfg. makes a decent 17-caliber cleaning rod that is reasonably stiff and doesn’t kink too readily. It is available sizes from 7″ to 36″, either bare stainless or with a nylon coating. We prefer the nylon-coated version, in either 26″ or 36″ lengths, depending on barrel length.
If you have a high comb on your rifle, you may need extra length to avoid interference with the rod handle. Use this formula to determine correct rod length: Length of barrel + action or breech rod guide length + 2-3″ clearance + high comb if applicable = total rod length needed.
There are other quality 17-cal cleaning rods, but we’ve used the Dewey and it functioned well. The nylon coating cleaned easily and was gentle on the throat and crown. You should clean the coating before and after each use to ensure it does not embed grit or other contaminants.

Some clever F-Class competitors, such as Forum Member Peter White, have fitted remote flexible-drive-shaft windage controls to their front rests. This allows you to easily adjust windage with the twist of a knob without leaving your shooting position. Until recently, if you wanted a flex-drive windage system on your rest you had to fabricate it yourself.
Now you can enjoy the advantages of remote flex-drive windage adjustment in a ready-made product. Bald Eagle Precision Products has introduced a trio of front rests with “factory” flex-drive windage controls. There are three (3) models. The model BE1006 boasts a heavy, cast-iron slingshot-style base with heavy-duty 1/2″ x 13 TPI threaded feet. Weight is 20 pounds without front bag. This heavyweight model BE1006 should be popular with F-Classers shooting the 7mm and magnum calibers, as the added mass provides great stability.
The slingshot base design has a longer rear leg, bringing the windage control closer to the shooter’s hand. Bald Eagle’s model BE1005, shown below, shares the clever slingshot design of the ME1006 along with remote windage adjustment, but the BE1005’s base is cast aluminum. This drops total weight to 11 pounds (without front bag), making the BE1005 easier to carry than its heavyweight cousin. The aluminum-based BE1005 saves you 9 pounds compared to the BE1006.
The third new Bald Eagle front rest, model BE1004, features a more conventional triangle pedestal design. Like the model BE1005, it has a cast aluminum base, and weighs 11 pounds without front bag. All three Bald Eagle rests, BE1004, BE1005, and BE1006 can be equipped with over-size disc-type feet (item BE1007) for greater stability in soft or soggy ground.
SEB-Made Bags with MicroFiber Tops Available for Bald Eagle Rest
Bald Eagle offers high-quality front bags to fit its line of front rests. These bags are crafted by SEB and feature a low-friction, smooth microfiber surface. We have used SEB front bags with micro-fiber tops and we think they are some of the best available. The microfiber allows your rifle to slide easily without powders, silicon sprays, or other surface lubricants. Having two fill spouts, the front bags are also easy to fill to the firmness level your gun prefers. The front bags measure 4-5/8″ wide by 1-3/4″ tall, and come in three configurations: 3″ wide for F-Class and Benchrest; 2-1/4″ wide for medium-wide flat forearms; and a 3″ radius for sporter/hunting stocks.
All Three Bald Eagle Rests, Front Bags, F-Class Feet, and other accessories can be purchased from Grizzly Industrial and other retailers nationwide. Here are “street prices” of the three rests, as sold on Grizzly.com:
BE1006 is priced at $475.00 but has an introductory sale price of $425.00. BE1005 is priced at $450.00 but has an introductory sale price of $399.95. BE1004 is priced at $450.00 but has an introductory sale price of $399.95.

Burris is expanding its line of Eliminator range-finding Laserscopes. Burris is rolling out three new Laserscope models: 4-16x50mm Eliminator III, plus 4-12x42mm Eliminator II, and 3.5-10x40mm Eliminator. The innovative Eliminator technology, first introduced in the original 4-12x42mm model, combines a variable-power zoom optic with a built-in Laser RangeFinder. The range-finder calculates the distance to your target, and then displays a red dot range-corrected hold-over point. Just put the dot on your target and pull the trigger. You don’t have to spin your elevation knob.
New Eliminator III Ranges at All Powers
The new top-of-the-line 4-16x50mm Eliminator III is slimmer and less bulky than the original Eliminator. The Eliminator III features a new X96 reticle that will range at any magnification, and it offers a more sophisticated ballistics solver. With the Eliminator III you can now enter BOTH the bullet drop at 750 yards PLUS the ballistic coefficient (BC) for the specific bullet you are using.
The Eliminator III’s X96 reticle also incorporates a new windage compensation system of dots that show lateral hold-off points. By using the dots, you can compensate for wind-drift without dialing the windage knob. The digital readout displays a 10 MPH Wind Value as a “Dot Value” for the shooter’s specific cartridge at the indicated range. Suggested retail price for the new Eliminator III is $1,499.00.
Eliminator II Features Angle Compensation and Remote Activation Switch
The new 4-12x42mm Eliminator II laserscope features the X38 reticle. Burris claims the Eliminator II can range to 999 yards, but we suspect that’s optimistic. We are pleased that the new Eliminator II comes standard with angle compensation that helps hunters make uphill and downhill shots. The Eliminator II comes equipped with a remote activation switch that can be attached to the firearm’s forearm or the scope’s objective bell. Like the other Eliminators, you can program the ballistics solver for different guns/loads. Suggested retail price for the Eliminator II is $999.00.
The new Eliminator 3.5-10x40mm is similar in design to the original Eliminator. The 3.5-10x40mm ranges out to 800 yards, with a ballistics solver you can program for any gun/load. The 3.5-10X Eliminator must be set to 10x power when ranging targets or trophies. Suggested retail price is $799.00.
$100.00 Rebate on First Gen 4-12x42mm Eliminator Laserscope
The original Eliminator 4-12x42mm was the first affordable laser rangefinding riflescope, and now there is a $100 rebate on the first-generation 4-12x42mm Eliminator, making it even easier to fit within your budget. Visit www.BurrisOptics.com for more information.

What outdoorsman would not want a thermos configured like an giant-sized shotgun shell? This is an ideal gift for the hunter who may be spending long hours in a cold blind or sitting in a tree stand. Stansport offers shotshell-style thermal bottles in two sizes. The “12 gauge” bottle holds 25 ounces of liquid while the smaller “20 gauge” bottle carries 16 ounces. Both bottles feature a faux brass screw-on top that doubles as a drinking cup. There is a second, gasket-sealed stopper with a quick-dispense feature. This allows you to pour the hot contents without needing to remove the screw-in stopper. We like that feature — that’s one less item to drop on the ground.
These shotshell thermal cannisters are offered in four colors: Red, Black, Green, and Yellow. All shotshell thermal bottles feature double-wall 18-8 stainless steel insulated construction with insulated cap. Prices for the red, 25-oz. version start at $25.50 on Amazon.com. (Other colors may cost more).
Shotshell Thermos Demo Video on YouTube
A hunter who owns one of these Shotshell Thermos bottles has posted a video of his bottle on YouTube. The video will give you an idea of the size of the cannister and how the outer cap/cup and inner stopper work. CLICK HERE to watch Shotshell Thermos Video.

Our friend Pascal Fischbach from France offered us a sneak peak at the final production version of a new benchrest rig from Argentina. Pascal reports: “I’ll be in Buenos Aires soon and will meet Carlito Gonzales, maker of the CG M1 Thunderbolt benchrest rifle that performed so well at 2010 Supershoot and WBC10 last August in the hands of Dr. Cris Rando.” Pascal has ordered one of these rifles for the 2013 benchrest season. If you want more information about the CG M1 action or complete rifle, contact Pascal through his Facebook Page.
Pascal tell us: “The CG M1 action is a short, tight but smooth 3-Lug, Right Bolt, Left Port, Right Eject model. The receiver features a special 66mm-long tenon with threads in the center area and two bearing-centering areas on each side of the threads. Any gunsmith will be able to chamber additional barrels with the data and tools provided. This action offers strength and rigidity to enhance both accuracy and longevity. Carlito’s trigger is excellent — I recommend keeping it. The complete rifle will feature special quality rings that mate to the top of the receiver. Barrels can be chambered with your custom reamer or with CG’s conventional 6PPC reamer or even a PPC-AI chamber design (PT&G) that Carlitos realy likes. Price for the complete rifle will be very competitive.”
One reason this rifle performs so well is the innovative stock design. The fore-arm is very low profile in the front. At the back of the stock, an exaggerated Vee profile aids tracking and reduces vibration. Pascal says the stock tracks very straight for the first couple of inches during recoil, and the marked Vee in the rear makes it ride on the sides of the bag ears, not the bottom stitching. This helps quell vibration and improve damping. The carbon construction makes the stock “stout and stiff”.
The fluted 3-Lug Bolt is extremely well-machined.
The tang on the 2012 version has been shortened for weight reasons. There’s still plenty of bedding area on the main body.
Super-Sized Action Offered for Long-Range Rifles
For long-range shooters, Carlito Gonzales has also crafted a larger 600/1000m version of the CG M1 designed for bigger cartridges used in long-range competition. We don’t have any specifics on price or delivery date, but the action looks nice. The extended front section should provide excellent support for long, heavy barrels.

Review by German Salazar, Contributing Editor Tom Sziler, a very talented machinist and shooter, is now offering handsome billet aluminum loading blocks through CNCshooter.com. I recently bought a set and am very impressed with their quality. You can see I have the cartridge type engraved on my .30-06 block. Tom makes these in all case head sizes and will engrave just about anything you like on the side. Tom’s been a bit backlogged lately, but for a custom product, delivery was more than speedy. I received mine in about three weeks.
2011 Update (By AccurateShooter.com Editor)
Tom has recently expanded his line of CNC-milled loading blocks, which are sold through his website, CNCshooter.com. There are now four price levels for the 50-round blocks: $16.50 for .22LR blocks (Small); $28 for most centerfire cartridges (Standard); $31 for very large cartridges such as .338 Lapua, .45-70, etc. (Large); and $33 for BMG, CheyTac, etc. (Jumbo). Tom also offers an “economy” version of his 50-rd loading block for just $19.00. These are made to the same quality and precision as the original loading block; however, they are crafted from 3/4″ aluminum and have NO engraving.
New Products: 25-round Block and Range Tray
New this year from Tom is a smaller, 25-round loading block, priced at $17.50. This has the same basic design (with engraving) as the 50-rounder, but it is half the length (with half the capacity). This is perfect for low-quantity handloading. Some guys like to use the 25-round ammo block when shooting in competition. It makes for a quick, handy ammo caddy. But even better for competition is Tom’s new Range Tray shown below. It has a milled-out tray for empty brass or small parts. Price is $28.00 for most cartridges up to WSM head diameters.
If you order from Tom, add $5 for shipping up to 2 pieces, or $10 for 3-7 pieces. Loading blocks ship in USPS flat-rate boxes. Tom prefers to receive payment by way of U.S. Postal Money Order. Send money order, order specs and your shipping address to:

This report was first published in 2011. Due to numerous requests, we are republishing the story. The time is right because the Giraud Annealer is currently on display on vendors’ row at Camp Perry. Doug Giraud will be at Perry through the morning of August 4th.
Doug Giraud of Giraud Tool Company has created a new bulk Cartridge Annealing Machine that uses an innovative vertical hopper feed. Giraud’s patent-pending design allows the machine to process as many as 700 .223 Rem cases with no hand-feeding required. The new Giraud Cartridge Case Annealer, using a single propane torch, will anneal most cases in 6-8 seconds (that dwell time will melt 750° Tempilaq inside the neck). Annealing dwell times can be adjusted using a simple rotary knob on the right side of the machine. During annealing, each case is rotated in the flame through the motion of a Trolley Plate which moves right to left under the case. At the left-most limit of Trolley Plate movement, each case drops vertically down for air cooling. CLICK HERE for Giraud Annealer Users’ Manual (PDF)
The Giraud annealer uses a large, V-shaped hopper to hold up to 700 .223 Rem cases or 450 .308 Win cases for annealing. You can switch from small cases to larger cases by swapping out the rotary Feeder Wheel below the hopper. Changing Feeder Wheels takes a couple minutes. Five available Feeder Wheels (with different size cartridge slots) let you anneal pretty much any size cartridge — from .17 Remington all the way up to .50 BMG. The common .223 Rem and .308-sized cases used by High Power shooters are served by the Red Feeder Wheel and Blue Feeder Wheel respectively. The Blue Wheel will also work with 6mmBR, .243 Win, and .30-06 cases. The three other Feeder Wheels are: Black (.300 Win Mag); Purple (WSM, RUM, RSAUM, Lapua and Norma Mags); and Green (.50 BMG). For the large mags you also need to switch to a wider Trolley Plate.

Giraud Annealer Can Process Hundreds of Cases in One Session
The biggest advantage of this machine is its ability to run with minimal user “intervention”. Once you’ve determined the right dwell time for your cartridge type, you can stack hundreds of cases in the V-shaped hopper, turn on the torch and let the machine do its thing. With a typical 8-second dwell time, the Giraud annealing will process about 450 cases an hour. While other multi-torch annealing machines may be faster, Giraud prefers the single-torch design: “With a single torch, you can control total heat input over a longer time. You don’t over-cook the case in a half-second — you have a lot more leeway with a 6-9 second dwell time.”
Yes the case spins in the flame — the Trolley Plate running under the case rotates it. The user may wish to experiment with the speed control knob on the right side panel near the power switch. Typical annealing operations will require the cartridge cases to be positioned in the torch flame for between 6 and 9 seconds.
Much smart thinking went into the Giraud Annealer design. Doug Giraud tells us: “We went through a couple different ideas. Our key goal was to vertically stack a large quantity of cases that would self-feed. The automatic feeding capability of the machine means that the operator can perform another task while the machine is running. The user doesn’t have to load cases one by one. I would caution, however, that you don’t want to turn on the annealer and just walk out of the room… but you can be doing some other reloading task while the annealer is running nearby.”
Giraud wanted a machine that could process lots of cases cheaply and efficiently. The machine’s single torch is optimized to run on inexpensive propane gas. Doug says: “You can process 15,000 cases on a single $2.00 disposable propane bottle.” If the user wants faster processing, the torch is rated for MAP gas, but Doug cautions that, “with more heat, you’ll have to adjust the dwell time accordingly.”
Giraud Annealer Impresses High Power Shooters
The new Giraud Cartridge Case Annealer has already attracted considerable interest. Doug took some early production models to Camp Perry in 2011, and he immediately got orders for 50 machines. Doug told us: “The response from the High Power guys was amazing. There was a pent-up demand for a simple, robust annealer that can process hundreds of cases without having to feed them one by one, and that’s what we created. We’re selling these units as fast as we can build them.”
Giraud Annealers Cost $435.00 — Delivery in Six Weeks from Order Date
Doug has components for 100 more machines, and he’s producing them at a rate of 15 units per week. He’s been back-ordered, but if you order soon, Doug believes he can ship the Annealing machines in about six weeks from date of order. The basic price, with one Feeder Wheel and one Trolley Plate, is $435.00. Additional Feeder Wheels cost $20.00 while extra Trolley Plates are $10.00. For more information, visit GiraudTool.com.

Swarovski has just announced a truly revolutionary spotting scope system. Imagine a “normal” spotting scope sliced in half, with separate objective (front) units and separate eyepiece (rear) units. This way you can have both straight and angled viewing options, and you can select from three (3) different objectives (65mm, 85mm, 95mm), depending on the light-gathering and max magnification you need for the job (and the weight you’re willing to carry).
The new Swarovski Optik ATX/STX Modular Spotting Scope combines a straight (#49902) or angled (#49901) rear eyepiece module with any one of three front objective sections, the largest of which is a whopping 95mm. All three available objectives have coated HD lenses for high contrast, low chromatic aberration, and optimal light transmission. These lenses are bright, with excellent color fidelity.
Both eyepiece modules have extended-eye-relief ocular lenses, with a “field-flattener” lens design that provides high contrast and correct geometry all the way out to the edge of the image. The eyepiece modules deliver either 25-60X or 30-70X power depending on front module. NOTE: The eyepieces are built into the rear modules — they are non-removable and you can’t swap in a third-party eyepiece. However, digiscoping adapter can also be fitted in the rear.
Watch Video to See Product Features and Lens Modules Changed in Field
With front and rear modules joined, the zooming and focusing rings are located right next to each other. This allows you to zoom quickly, and then easily fine-tune the focus without moving your hand. Centralizing both controls is smart because you don’t have to take your head away from the eyepiece to look for one control or the other. Your hand can stay in one position. We’ve always liked the large-diameter focus rings on Swarovski spotting scopes. Now, with the new modular Swarovski system, you get the advantage of a large-diameter, centralized zoom control as well.
Big Money for Complete System
As you might expect, the Swarovski ATX/STX system commands a premium price. Either angled or straight eyepiece module is $2179.00 at EuroOptic.com. The 65mm front objective module is $879.00, but you’ll pay $1599.00 for the 85mm objective module. The biggest 95mm objective module costs $1899.00. So, for an angled rear module plus the jumbo 95mm objective, you’re looking at $4078.00 total. If you want BOTH rear modules AND the 95mm objective, you’ll need to pony up $6257.00! That’s got to be some kind of record for consumer spotting scopes. The minimum you can spend (for one rear module and 65mm objective), will be $3058.00, which is still pretty pricey. There are some significant advantages to this modular system though. For example, transport and storage is simplified, and we like the ability to choose the objective size based on the “mission”. You don’t need a 95mm objective to see bullet holes at 100 yards. But at long range, a bigger objective can be very useful.

Talented tool-maker Curt Knitt has designed a better mousetrap — a new Concentricity Gauge that makes it easier than ever to get fast, repeatable results when measuring case and bullet run-out (aka “eccentricity”). The breakthrough design feature is the large-diameter wheel which spins the case. With most other concentricity gauges you must rotate the case with your finger(s). Anyone who has tried this knows that it is difficult to get a full, 360° rotation of the case without disturbing the indicator. Typically you can get two-thirds of a rotation or so, but then you have to reposition your finger to complete the rotation. Moving your finger often causes the case to jiggle or move slightly, and more often than not, the dial indicator jumps a bit, interrupting your measurement. Been there, done that.
Drive Wheel Smoothly Spins Cases for Fast, Error-Free Readouts
With the new Accuracy One Concentricity Gauge from CTK Precision, the rubber-rimmed drive wheel has a much larger diameter than any cartridge case (7:1 diameter ratio on magnums). So, when you rotate the drive wheel just a half-turn or so (using knurled knob on the wheel axis), you can easily and smoothly turn the cartridge three (or more) full rotations. The drive wheel maintains a constant, even load on the case, so the case doesn’t wobble and the dial indicator gives a continuous, un-interrupted read-out. What’s more, clever cartridge support design geometry pulls the case back against the rim stop as you engage the drive wheel. This holds the case in position laterally during measurement. Morever, this allows very fast one-handed operation. You don’t have to hold the case down with your fingers while maintaining side force against the case rim stop.
Watch Video Showing Concentricity Gauge Used with Small and Large Cartridges
The Accuracy One Concentricity Gauge works with the full range of cartridges — everything from .22LR to .50 BMG. Adjusting the tool for different-length cases is incredibly easy, because the roller blocks (case supports) are held in place by magnets. You just slide the blocks to the desired position — no tools needed! The indicator stand is also held by magnets so it can slide to any position you want along the case body or bullet. And, the indicator can be moved to the front rail and rotated 90°. This way you can measure on the inside of the case neck.
Does this new design really work? Absolutely — it works brilliantly and it’s FAST. Watch the video and see for yourself. We could do two-rotation (720°) measurements on cases in a third the time it takes to do a one-rotation gauging operation with other tools. And the actual measuring operation can be done one-handed, leaving your free hand to pic up the next case (or bullet) to be measured. And yes, this tool can also measure bullet concentricity — measured from tip, ogive, bearing surface, and/or boatail.
1. Directional Drive Wheel pushes the cartridge or bullet into the stop for accurate, repeatable readings with equal pressure. The replaceable rubber drive ring will not harm cartridges or bullets.
2. Two-position bullet and cartridge stop.
3. Precision ball bearings provide friction-free movement.
4. Heavy steel base with E-coat finish and bolt-on rubber feet.
5. Indicator stand and roller blocks ride in machined slots and are held in place by N42 Neodymium magnets. This allows rapid, smooth, tool-free adjustments.
6. Indicator stand can be place in front OR rear machined slots. This allows for both internal and external measurements.
7. Fine-Adjustment Horizontal Indicator Stand allows very precise indicator angle/load adjustments.
8. Indicator Stand will accept horizontal indicators that are .350″ wide or narrower, and are 1.75″ to 2.25″ from the indicator contact point to the center of the main body.
9. Adjustable mechanical arm stop holds the arm up for one-handed operation.
10. Precision Drive Wheel has a 13:1 ratio for .22 rimfire, 7:1 for magnums, and 3.7:1 for 50BMG.

Looking for the perfect rimfire training rifle, one that has the look, feel, and ergonomics of your favorite centerfire field/tactical rifle? Well here’s a unique opportunity. EuroOptic.com is putting together a special limited edition run of 49 Sako Quad rifles, configured exactly as the buyer specifies, with McMillan Stocks, Lilja Barrels, and Cerakoted Metal. There will only be 49 such rifles available, and the deadline to order is July 31, 2012. EuroOptic.com has a few offerings left, but it expects all 49 Special Edition Quads will be sold by the end of this month.
The Sako Quad was a great concept — one rimfire rifle with a quiver of barrels in different rimfire chamberings. However, many potential buyers didn’t need or want all four barrels. Many potential buyers liked the idea of the Quad as a rimfire trainer, but they wanted a rifle fitted with a full-size, fiberglass stock, so the gun would have the same ergonomics and feel as their centerfire bolt-guns. That would make it the ideal rimfire training rig.
Well, this dream is now a reality. EuroOptic.com has decided to make a special limited run of 49 custom rimfire trainer rifles with premium components.
These Special Edition Quads will feature Sako Quad actions, McMillan fiberglass stocks, Lilja custom barrels, as well as quality third-party scope rails, triggerguards, and bolt knobs. The bedding and coating work will be done by GA Precision.
49 Special Quads — With McMillan Stocks, Lilja Barrels, and Cerakoted Metal
Each rifle will be “made to order” for the 49 lucky guys who sign up before orders close. The pre-order price (including ONE barrel, no optics) is $2195.00 + $30.00 for insured shipping in a hard card. Those who pre-order the rifles will be able to select the colors and special features they prefer. Buyers can chose among six (6) different McMillan stocks (with your choice of finish). Each rifle comes with one (1) .22 LR barrel. For an additional $350.00 per barrel, you can also order extra Lilja barrels chambered for any of these rimfire cartridges: .22 WMR, .17 HMR, or 17 Mach 2.
Each rifle will have the following standard features:
SAKO Quad receiver engraved with EuroOptic Logo and 1 of 49, 2 of 49 etc.
Lilja custom drop-in bull barrel in .22 LR. Other barrels/calibers can be added.

If you use a balance-beam scale to weigh powder and reloading components, here’s a clever way to magnify the view of the beam tip. Of course you can use an old-fashioned magnifying glass, clamped in place, to upsize the view. But now there’s a parallax-free, electronic solution that works for anyone with an iPhone or Android OS smartphone.
Forum member Allan E. (aka “1066”) discovered that he could use the camera on his smartphone to display and magnify the image of a balance-beam tip. This works via a Magnifying Glass App you can download for free. Just turn on the smartphone, activate the Magnifying Glass App and zoom-in to suit your preference. Alan explains: “This saves those tired eyes. It’s much more accurate because there’s no parallax — the lens is directly in line with the pointer so we can see [the pointer] off the screen from any angle. It’s a much clearer view, and it costs nothing.”
You’ll need to fabricate some kind of stand or clamp for the phone. Allan created a smartphone mount with a bit of wire, rubber bands, and a bullet box. You can see the system working in the video below. (The video starts by showing a webcam + laptop balance-beam monitor system. The Smartphone system demo begins at the 1:30″ time-mark.)
Magnifying Glass Apps for iPhones and Android Phones
There are numerous ‘magnifying glass’ programs for Apple and Android smartphones that use the built-in camera. Most include a zoom function and auto-focus. You might try a couple different Apps and see which works best for you. Some perform better in low light, while others resolve better. All of the following have 4-star or better user ratings:
American Tactical Imports (ATI) has introduced its new ATI Omni Lower Receiver, a multi-caliber AR15 lower made of reinforced polymer. Since it was designed to milspec dimensions, ATI claims the Omni polymer lower is compatible with most current AR15 lower parts kits, grips and stocks. ATI says the durable polymer material “can withstand harsh environments as well as everyday wear and tear.” The Omni lower will be available as either a stripped lower, OR a complete finished kit including all lower internal parts and collapsible stock. ATI claims the Omni lower has tested reliably with .22 LR, 5.56×45 (.223 Rem), and .410 but is “not recommended for larger calibers“.
The Omni stripped lower has an MSRP of just $49.95 while the complete finished kit has an MSRP of $129.95. The Omni lower comes in either black or dark earth colors. The .22LR version is available now. The .223 (5.56) version is slated for release in August, 2012, and a .410 version will be offered in the fall. To learn more about the ATI Omni Polymer AR15 lower, visit www.AmericanTactical.us.
Editor’s NOTE: This story is based on a press release by ATI. We have not examined or tested the product. Accordingly we can give no opinions as to fit/function, durability or safety. Likewise, we cannot venture an opinion as to whether the ATI Polymer lower would be legal in restrictive jurisdictions such as California. Nonetheless, this is an interesting technology that may prove useful in some applications. For example, the inexpensive ATI lower could work well with the Crosman MAR177 AR15 Airgun Upper, keeping total system cost down.

Product Preview by Boyd Allen Marsh Industries LLC of Cave Creek, Arizona, has just started production of its new “Saguaro” benchrest action. (Saguaro is the distinctive tall cactus plant found in the Southwest.) If the Saguaro action looks familiar, that’s by design. The idea was to produce a Panda-type action with 1 1/16″ removed from the middle to allow for reduced weight, and importantly, shorter bolt “draw” during cycling. In addition, Marsh Industries wanted smoother function and optimal accuracy. In that quest, Marsh crafted a state-of-the art striker assembly, configured specifically for short cartridges typically used for 100- and 200-yard benchrest matches.
The Saguaro action is like a Stolle Panda with 1 1/16″ removed from the middle.
Design and Testing of New Saguaro Action
After spending some time with “Doc” Marsh, (the owner of Marsh Industries), I must say that I am impressed with his new product. After learning what has gone into the design and production of these actions, and hearing how well Saguaro prototypes shot, this is one action I want to add to my collection.
Beneath the shiny exterior, the heart of any benchrest action is the striker assembly. Its specifications and adherence to tolerance are a formula that ultimately determines the potential of the action. Striker fall, weight, and spring rate, all work together to put the sharpest edge on accuracy, or if they are not right, result in run of the mill (for a benchrest action) accuracy, even if all the other details are perfectly executed. Rather than leave these details to the expertise of one person, several big names in the benchrest community were consulted about this part of the design. Intelligent input was received, and the design was improved from one prototype to the next. The final result is impressive to say the least. When the late prototype Saguaro was tested in a very good tunnel, using a rail-gun, the results were unequivocally outstanding. (Editor: This means the Saguaro action shot small enough groups to be “more than competitive” with any other hardware on the market.)
Saguaro Actions Can Use Barrels And Stocks Now Fitted to Pandas
The truth is that no one can quite put his finger on what makes the difference between a good action and a great action. Designs are created, actions built, they become parts of rifles, and only then is the truth revealed. Whether you believe that it was skill or luck, it would seem that the details that comprise this new action just happen to have the exact right stuff. For many of you, who already know how your barrels shoot on your rifles that have Panda actions, for the first time, a direct comparison is available. This is because Panda barrels fit Saguaro actions. So current Panda owners can remove one of their barrels, place it on a Saguaro-actioned rig, and see if the barrel shoots as good or better. That allows direct testing of one action vs. another.
You can use that closet full of barrels, on your new action, without modification, (and have a couple of more ounces toward that tuner that you have been waiting to try). For that matter, other than having to do a little filling in at the front of the action, you can replace your Panda with a Saguaro, and keep using the same stock. That offers a significant savings on a new build.
Saguaro Actions Start at $1050.00
For serious benchresters, an action that comes out of the box a potential winner is almost priceless. Saguaro actions will cost $1,200.00 polished, or $1,050.00 with a 400 grit finish. That’s reasonable given the build quality and performance. While you could pay a bit less for some other actions, if you are in the game to win, a less-than-competitive action isn’t worth owning (even if it is inexpensive).

And so there you have it — Part One of my report on a brand new action. Hopefully, in the not too distant future, I will have a chance to do more than just cycle the bolt (felt good) and actually shoot a rifle built around one. Until then, I will have to content myself with trying out some of Bergers new Column bullets, and doing some more work with the slower but otherwise identical brother to the yet to be released Accurate LT 32 powder, some of that Canadian 2015, as soon as the temperatures get out of the triple digits on a day when the wind is suitable.
