Many of our readers know Joel Kendrick, one of America’s top mid-range shooters. Joel is a two-time IBS 600-yard Shooter of the Year, and we have featured Joel’s match-winning 6×44 as one of our Guns of the Week. Joel now works with MMi-Trutec, specializing in the salt-bath nitriding process. This is a surface-hardening procedure for steel that creates a super-hard, low friction layer for the top 10-20 microns of the metal. Barrels treated with salt-bath-nitriding show much improved wear resistance and reduced friction.
For match rifles, varmint rifles, and hunting rifles, the most significant benefits of salt-bath nitriding are enhanced barrel life, and easier cleaning. Joel’s own F-Class rifle has a nitrided stainless barrel with over 5000 rounds — and it still holds 1/4 MOA at 100 yards. Other well-known shooters, such as John Whidden, have observed that nitrided barrels can shoot longer strings of fire between cleanings, with no reduction of accuracy. What is the cost of nitriding? As Joel explains in the video below, nitriding a single barrel costs $60.00, but there is a minimum first-time lot charge of $200.00. If you submit multiple barrels at the same time, the price per barrel can be reduced significantly. For more info, visit the MMI-Trutec website or contact Joel Kendrick by phone (704) 616-6442, or via email: joelkndrck [at] aol.com .
Is there a downside to nitriding? First, the nitriding process results in a BLACK matte or satin finish. If you like the natural silver finish of stainless steel, you shouldn’t nitride your barrel. Second, and most importantly, the salt-bath-nitriding process creates a surface so hard that you can NOT re-cut the chamber with normal reaming tools. Therefore, before nitriding, the barrel must be finished chambered. Basically the barrel should be fully finished, crowned, chambered and headspaced before nitriding. NOTE: MMi Trutec CAN mask the crown during nitriding so that the barrel can be re-crowned at a later time.

We had a chance to visit with Jim Kelbly of Kelbly’s Inc., at SHOT Show 2010. Jim had all the new March scopes on display, including the amazing 8-80x56mm long-range scope, part of March’s ground-breaking 10 times zoom range series. Jim reviewed the March line-up, explaining the many high-magnification models available for precision shooters.
Jim also showed us the stainless Grizzly II action and the new Atlas series of stainless actions. The Atlas actions are designed for varminters, tactical shooters, and long-range shooters who want an affordable stainless action with a Remington 700 action footprint. The Atlas actions should be a simple drop-in installation for stocks inletted for Rem 700s. At the close of the interview, we asked Jim about the future of benchrest competition. Jim believes that we will see more cross-over of short-range shooters into the long-range disciplines (and vice-versa), along with growth in the F-Class and tactical disciplines.

If you recently purchased a Remington 40X rimfire rifle from the CMP, and the bolt is old, worn out, or missing altogether, take heart, Dave Kiff of Pacfic Tool & Gauge (PTG) has a solution.
For a $199.00 “locked-in price” for AccurateShooter.com readers, PT&G offers a complete Remington 40X replacement bolt for CMP Rem 40X rifles. Even if your original factory 40X bolt functions, the replacement bolt should fit better (with less slop) and provide more consistent ignition, shot after shot. We won’t promise improved accuracy, but we predict that you get fewer unexplained flyers with the Kiff replacement bolt. Below, the charming Ashley Kiff explains the $199.00 special offer for our readers.

Manners Composite Stocks builds very strong, stiff stocks employing advanced manufacturing methods and high tech carbon fiber materials. In this video, stock-maker Tom Manners showcases his new products for 2010. These include the handsome new MCST 5A Tactical stock, composed of 30% carbon fiber, 65% fiberglass. Though as strong as any comparable stock on the market, the MCST 5A weighs just 4.1 pounds. Tom also displayed his impressive “long wheelbase” F-Class stock. A full 7″ longer than any other F-Class stock on the market, the Manners F-Class stock features all-carbon construction and a unique “fish-belly” design that provides extra rigidity so the stock tracks smoothly without the “springboard effect” common to some other low profile stock designs.
Tom also previewed the new Manners Mini Chassis, an integrated v-block/bottom metal/mag carriage. Manners’ Mini Chassis can be installed in one of Manners stocks or other designs, and it provides a rock-solid, “bolt-in and go” mount for a Rem-700 footprint action. The Mini Chassis takes both 5-round and 10-round AI magazines.

 Wisconsin’s Bartlein Barrels currently produces some of the most accurate cut-rifled rifle barrels in the world. We had a chance to chat with Bartlein barrel-makers Tracy Bartlein and Frank Green shortly after the doors opened at the 2010 SHOT Show in Las Vegas. Frank and Tracy weighed in on some of the “hot topics” in the barrel-making business: Gain Twist and the advantages of single-point cut rifling. In this interview, the “boys from Bartlein” discuss current trends in barrel-making, including what’s “hot” in short-range benchrest and the emergence of 7mm barrels for F-Class Open competition. Tracy also offers his opinions on cut rifling vs. button rifling, and he explains how modern technology has helped make modern barrels “better than ever”.

One gun, many calibers. That’s the concept behind Gary Eliseo’s new modular long action tube gun. By offering two different lower assemblies, along with swappable bolts and barrels, Gary’s versatile new RTM (Remington Tactical Modular) chassis can shoot a wide range of chamberings, from the midsize cartridges (such as 6XC) all the way up to the .338 Lapua Magnum. Eliseo’s RTM provides the tactical shooter with unrivaled versatility in a single package with consistent ergonomics and control function. You’ve heard the old adage, “beware the man with one gun.” Well that’s especially true if the one gun is built on the Eliseo RTM platform. To our knowledge, the RTM is first tube gun that can shoot everything from a 22-250 up to the .338 Lapua Mag. It’s a remarkable feat of engineering.
Gary provided this initial report: “I wanted to give Daily Bulletin readers a peek at the new RTM chassis I’ve been working on. Designed to accept the Remington 700 long actions or custom long action Rem clones, it will be available with two lower units. With the shorter lower, users can run short action cartridges like the 6-6.5×47, 6XC, 6.5 Creedmoor, 6.5×47 Lapua and .308 using AICS 5- or 10-round magazine. Or, with the longer lower (and a different barrel and bolt), you can shoot the .300 Win Mag up to the .338 Lapua Mag using AI 5-round single stack magazines.” Gary adds: “I’ve been working with John Pierce on this project — he’ll offer an action ‘package’ which will include a long action, two bolts, and even two barrels for those who want all the options.” Eliseo’s new RTM chassis comes equipped with an improved ambidextrous cheek piece, Gary’s new folding VRGS (vertical rear grip system), and a pair of quick detach sling swivel cups.

Here’s your chance to own a piece of benchrest history — A “classic” 6PPC benchrest rifle built by renowned smith and benchrest shooter Seeley Masker. Up for auction right now on Gunbroker.com is a pretty blue Heavy Varmint rig, built by Seeley on a blued Hart 1A action. The barrel is a 20″ Hart, marked: “Seeley Masker 6PPC .262 Neck”.
For those young folks who haven’t heard of Seeley Masker, Seeley was a “legendary BR gunsmith, an innovator, and a major force in the development of Bench Rest shooting” (AllinWA writing on Benchrest Central). Forum member Butch Lambert notes: “Seely Masker built my first two rifles. The work was superb”. And noted tool-maker (and smith) Alan Warner says Masker would be included on any “short list” of great early BR smiths. A Masker rifle would be a piece of “treasured history” according to Warner.
The rifle is Gunbroker Auction #152079095. The current bid is $615 with no reserve. Here’s a chance to get a nice, older PPC with a great “provenance” for under $800.00.

We know many readers took advantage of the recent CMP sales of Remington 40X rifles and barreled actions. And now many proud new 40X owners are looking for upgrades. A brand new, precision-machined bolt can improve both the accuracy and the reliability of rimfire rifles. For a limited time, Pacific Tool & Gauge (PT&G) is going to offer complete 40X rimfire bolt assemblies for under two hundred bucks.
Dave Kiff of PT&G recently told us: “After all the feedback we’ve received regarding the 40X Rimfire bolts, Pacific Tool & Gauge is going to run 250 pieces and is currently taking orders. To place your order, please give us a call at (541) 826-5808. If you place your order during the first run, the price for the complete bolt assembly (handle installed) is $199, but if you miss the first run, the price will be going up to $225.”
If you’re interested in adding a new, high-quality bolt to your 40X rimfire action, now’s the time to buy. We suspect PT&G will sell out on the initial order quickly.

If you use mass-production ring sets, other than Burris Signature Rings or SAKO Optilock Rings (which both feature polymer inserts), you can benefit from lapping your scope rings. Lapping your rings, when done properly, with the right tools, can improve the fit of the rings, reducing bending forces and stress on the scope. Properly-lapped rings are also less likely to leave prominent marks on your scope tubes.
Forum member Boyd Allen is a strong advocate of ring lapping for factory-produced ring sets. He’s tried various lapping tools and he believes that the Kokopelli system is one of the best available. Custom crafted in Kalispell, Montana by John Werre, the Kokopelli lapping system combines a specially-machined lapping rod with patented flat-ended scope alignment bars.
Kokopelli Lapping Tool
John Werre, Kokopelli’s owner, explains why his lapping tool works better than most others: “No one was making a lapping bar that would lap anything more than the bottom half of the rings and they were made of rolled stock and only a very short stroke was possible, rapidly wearing out the bar due to the limited area of use. I did something entirely different. I designed the bar to be used with the top halves of the rings in place and utilizing a long stroke thereby distributing the wear over the entire 12″ length of the bar. Why just do half a job?”
John adds: “Another problem was that the lapping compound would readily scrape off the bar, slide around and wear the bar out as fast as the rings. I added the spiral groove to stop the scraping off of the compound and later changed to a much softer steel and put a very rough, but carefully designed, finish to accept the lapping compound, actually allowing the grit to be driven into the surface of the bar. The nasty, scruffy rough finish is full of grooves and valleys of a depth designed to ‘catch’ the very sharp lapping compound, imbedding it into the bar. You then will wear out what you’re trying to lap rather than wear out the bar at the same time. The spiral grooves also cannot catch on the edge of the scope rings as can one which has annular grooves cut perpendicular to the axis of the bar in separate rings. I have very good reasons for every unique feature of my tools. Every aspect has a valid design behind it.”
Kokopelli Scope Alignment Bars
Kokopelli’s patented scope alignment bars have flat ends and work differently than alignment bars which use pointed tips. Kokopelli came up with a flat-ended design because alignment bars with pointed tips can yield a “false positive”, meaning the points can touch when the scope rings are out of alignment. To demonstrate, try this simple experiment. Take two ordinary pencils. With one pencil in each hand, hold them parallel with the pointed (lead) tips touching. Now simply move the outboard end of each pencil, while keeping the tips touching. You can see instantly that the tips can touch even if the pencils are way out of alignment. The same thing can be true of scope alignment bars.
With the Kokopelli scope alignment bars, each bar is an exact cylindrical projection of the interior of each ring. When you bring the bars together, if they don’t mate perfectly, i.e. if there is any gap between the flat ends when the bars are touching, then you know you have an alignment problem. Kokopelli claims that misalignments as small as .002″ can be detected. John Werre explains: “The bars actually are a three-dimensional projection of each ring ‘hole’. You’re looking at a solid representation of the hole through the ring. Put one bar in each ring and you can then compare the axial alignment of the ‘ring holes’ to each other. If the ends match and are flat together you have reconstructed the bars into one [cylinder] and the alignment is PERFECT.” Below, in Figure 1, you can see rings that are out of alignment. In Figure 2 you can see rings that are properly aligned. Interestingly, the misalignment illustrated in Figure 1 did NOT show up with pointed ring alignment bars. This amount of misalignment can create up to 3/16″ of scope tube bending (depending on ring spacing).
The function of the Kokopelli lapping tool and alignment bars are described in greater detail on the Kokopelli website. The lapping tool and alignment bars are sold separately, or as part of Kokopelli’s complete Accurizing Kit shown below. The kit, which combines Scope Alignment Bars, Lapping Bar, pointer rod, and lapping compound in a fitted box, costs $84.50 for 1″ rings, or $91.00 for 30mm rings. For more info, contact John Werre at Kokopelli Products, 3820 Foothill Rd., Kalispell, MT 59901; phone (406) 755-3220. NOTE: Kokopelli has maintained the same prices since 2003. However, due to increased costs of materials, John Werre plans to raise his prices by mid-January, 2010. You can get current pricing by ordering soon.
