Bartlein Delivers Precious Metals to NorCal Rifle Club

Norcal NPPRC Bartlein BarrelsNeed a premium cut-rifled barrel? Be prepared to wait six months or more. However, if you were a member of the NorCal Practical Precision Rifle Club (NCPPRC) you’d be sitting pretty right now. After receiving a boatload of new Bartleins (31 by our count), NPPRC’s Vu Pham announced on Facebook: “Our first batch of Bartlein Barrels has arrived!! This is less than 1/3 of our 2013 Club order!”

That’s an impressive supply of precious metal to be sure. Are those Bartleins worth their weight in gold? Not quite, but Vu and crew definitely have reason to celebrate. We hope all the folks at NCPPRC shoot lots of good scores with all those pretty new tubes. Yes, you could say we have “barrel envy” now.

California Pistol Micro-Stamping Requirement Goes into Effect

California Microstamping lawFrom now on, California will require all new-model semi-automatic handguns to be manufactured with microstamping technology (aka “ballistic imprinting”). This requirement went into effect on May 17th, when the California Attorney General’s office declared that technical and patent barriers to the implementation of microstamping had been removed.

To make a firearm compliant, firearms manufacturers must now engrave a gun’s make, model, and serial number on two distinct parts of each gun, including the firing pin, so that, in theory, this data is imprinted on the cartridge casing when the pistol is fired. If the microstamp on the end of the firing pin wears out, then the gun is considered “unsafe” under California law, and the owner may not sell or transfer the gun.

Read California Dept. of Justice Certification of Microstamping Technology Notice

California’s microstamping law was enacted way back in 2007. However, by its terms, the law did not go into effect until the technology was mature and patent rights were resolved. With the State government claiming that microstamping is now practical, new gun models must have microstamping capability in order to be approved for civilian sale in California. This will, eventually serve as a de facto ban on new-model semi auto handguns in California. Brandon Combs, Executive Director of the Calguns Foundation, explains: “Manufacturers are not going to create a special run of firearms with all of these very burdensome manufacturing technologies just so they can comply and produce firearms for one market.” At present, as far as we can determine, no major gun-maker currently offers a microstamping-capable, semi-auto handgun for sale in the United States — not a single one.

Current “California-Approved” Semi-Auto Pistols Can Still Be Sold — For a Time
The “activation” of California’s microstamping requirement does NOT mean that semi-auto handguns currently on the California “approved” list can no longer be sold. The current inventory of “approved” handguns are “grandfathered”, so they may be sold so long as the manufacturers continue to pay annual handgun roster registration fees to the State of California. However, any new-model semi-auto pistol — even one with a minor design change from a previous version — will be blocked from sale in California unless it has the microstamping feature. If a manufacturer stops producing a particular handgun, replacing it with a newer, upgraded version, that newer model cannot be sold in California unless it is microstamp-capable. (We should add that the microstamp requirement does not apply to handguns sold to law enforcement agencies.)

What we can expect is that, in time, as handgun manufacturers replace old models with new models (or make modifications to existing models), fewer and fewer new semi-auto pistols will be offered for sale in California. If, for example, Glock updates its Glock 17, the new model could not be sold in California unless Glock outfits it with microstamping capability.

NRA Plans Legal Challenge
NRA Attorney C.D. Michel says that microstamping is a flawed and impractical technology: “This is not going to help solve crimes. [Microstamping] is easily defeated… and can be used to lead police down false alleys.” Michel notes that criminals can easily defeat the microstamp by filing the tips of firing pins. Overall, Michel believes, microstamping will not reduce crime, but it will cut off the supply of handguns available to Californians. He stated the the NRA plans a legal challenge to the implementation of microstamping in California.

While there is virtually no “real world” evidence that microstamping has ever solved actual crimes, there are many important criticisms of the “ballistic imprinting” technology:

  • Stamped casing can only be traced to the last registered owner, not to the person who used the gun when the casings were stamped. In the case of a stolen gun, as is the case for most firearms used in crime, the stamped case would not lead to the criminal.
  • Criminals could collect discarded brass from a firing range and salt crime scenes with microstamped cases, thereby providing false evidence against innocent people and increasing the workload for investigators.
  • Microstamping is easily defeated. Inexpensive files will remove microstamping. Firing pins are normally replaceable and can be changed with simple tools or without tools. Firing a large number of rounds will wear down the microstamp.
  • Microstamping is an immature technology, and has not been subjected to sufficient independent testing. Transfer of microstamped marks to the cases is less reliable than proponents claim.

Navy Man Commissions Eye-Catching Blue .284 Win F-Open Rig

KT rifle .284 Winchester F-Class

Forum member Keith T. (aka “KT”) is in the U.S. Navy, so he has a fondness for seafaring, nautical color-schemes. Here is KT’s new F-Open rifle, smithed by Accurate Ordnance out of Winder, Georgia. The gun is chambered in .284 Winchester for Lapua brass (necked up) and 180gr Berger Hybrids.

KT admits, “It’s a little bit different than most in appearance!” But KT likes it that way: “When I had Accurate Ordnance build it, the only thing I specified was the stock, action, caliber and barrel length. I left the rest up to them. I think they did a pretty awesome job.”

The gun features a Pierce cone-bolt long action (with Jewell trigger) in a McMillan F-Class stock. The barrel is a Brux 31″, 1:9″ twist in the Brux “F-Class contour”. Sitting on top is the new Nightforce 15-55x52mm Competition scope with turrets and sun-shade coated blue to match the blue-coated action, bolt handle, rings, trigger guard and barrel.

The build came out great, but there were a few “bumps on the road”. KT explains: “This rifle took a long time to finish. When it comes to building guns I always joke and say if it weren’t for bad luck I wouldn’t have any luck at all. We started ordering parts in September 2012. Somehow I managed to order the stock from McMillan for the wrong Pierce action. After a bunch of scrambling and hard work on Accurate Ordnance’s part we were able to get my screw-up fixed. Then we ran into a few more snags. AO wanted to have the scope on hand before doing the coating. The first trigger was not up to standard with AO so they ordered another one and the list goes on. The rifle is finally done though and I couldn’t be happier.”

.284 Win Redux — The Lure of the ‘Straight .284 Win’

Editor: With Jerry Tierney steering a straight .284 Win to victory at the recent NBRSA 1000-Yard Nationals, we thought readers would appreciate a “second look” at this story. Our friend Bruce Duncan talks about the .284 Win and explains why it has proven so successful in long-range competition.

By Bruce Duncan, MT Guns

Building a Straight .284 Winchester
Sometime back–at least two years ago–Jerry Tierney confided in me that he was givng up on the 6.5s, and moving to the 7mms. “If you could only shoot one 7mm, Jerry,” I asked, “which would it be?” … “Straight 284 Win,” he answered.

So when I was thinking to rebarrel my 6.5×47 Lapua, in the fall of 2010, the .284 Win came immediately to mind. I am not about to argue the primacy of any chambering. I look at the dominance of the 6mm Dasher, at Missoula, say, or the recent NBRSA 600- and 1000-Yard Nationals and wonder.

And I’m reasonably convinced that none of us ever makes an entirely rational decision — one based purely on fact, and void of prejudice and emotion. But I knew a bunch of the U.S. F-Class guys were moving to 7mm, and decided to build one myself. This would be a NBRSA Heavy Gun, using my existing Barnard PC twin-port action, and my existing Shehane MBR Tracker stock. Going to the 7mm made sense to me — an accurate heavy bullet with a high BC, such as the Berger 7mm 180gr Hybrid, has a good chance of getting where one wants it to go. That’s particularly important when you’re shooting in tough wind conditions.

I ordered a 1:9″-twist barrel from Bartlein with 5R rifling and 1.250″ straight contour. (By the way, MT Guns has racks of Bartlein barrels if you need one right away.) I spoke at length with Ray Bowman of Precision Rifle & Tool (PR&T), who has immense experience with the .284 Win, and his fingerprints on a lot of winning rifles. Ray was supportive.

Bruce Duncan .284 Win Winchester

“The .284 Shehane isn’t enough bang for the buck”, Ray suggested. I sense he was telling me that I could achieve what I wanted with a standard .284 Win, without the cost of custom-run dies or the hassle of case-forming. I had David Kiff of Pacific Tool & Gauge cut me a reamer with a .313″ neck. I hadn’t decided on a bullet — I shoot Bergers exclusively — but watched the results from Phoenix in 2011, and noticed Bryan Litz did well with his .284 Win, shooting the Berger 180 Hybrid, as did Danny Biggs, shooting a 7mm RSAUM. I did some preliminary 100-yard load testing, and settled on a few loads I wanted to try (at longer range) with the Berger 180.

Shooting in good conditions on an Ojai, California morning, I tried three, five-shot groups with three different loads at 600 yards. One load in particular gave me two groups out of three at 1.8xx”. That’s pretty darn good at 600. The only surprise was that the bullets were seated to have the ogive just kiss the lands, rather than the slight jump that most were using.

Bruce Duncan .284 Win WinchesterIt turned out that my load development wasn’t a fluke. The gun shot well, taking Third Place, 6-Target Aggregate Heavy Gun Group at the 2011 NBRSA 1000-Yard Nationals in Sacramento. Together with my 6×47 Lapua Light Gun, I took Third Place Overall. (The LG also featured a Barnard Action, Bartlein barrel, and Shehane stock.)

Great Accuracy Is Possible
So I was not surprised when Ed Docalavich, one of MT Guns clients, wrote to say how happy he was with the .284 Winchester we built for him. He attached one of the proverbial “Wallet Targets” from load testing. You can see it at right. There are five (5) shots at 100 yards, in a ragged hole you could practically cover with the Excedrin tablet in the photo. Not bad for a stout-recoiling rifle. Ed’s gun features a Barnard P action, Bartlein 5R 1:9″-twist, 1.250″-straight barrel, chambered for a no-turn neck.

Like I said, I’m not about to argue the primacy of any particular chambering, and my hat is off to the 6mms that do so well at 1000 yards. But I like the idea of a heavier bullet; the Berger 180gr Hybrid seems like magic. And as you might imagine, I don’t think it’s any coincidence at all that Ryan Pierce recently set a new 1000-Yard F-Open Record shooting the straight .284 Winchester. (READ Pierce Record Story).

Heavy Artillery — Remarkable 7mm WSM with Joystick Rear Rest

Readers said they enjoyed our write-up of an innovative, offset-stocked Heavy Gun that set three multi-match Aggregate IBS records last year. If you’re a fan of “Heavy Artillery” here’s an impressive rifle from Forum member ‘Straightpipes’ that we spotlighted last year. If you missed it the first time — check out this engineering Tour De Force, complete with a custom-built, joy-stick REAR rest. We’re mightily impressed by the cutting-edge design and superb metal-work displayed by this “home-built special”. ‘Straightpipes’ certainly proved that American “know-how” and creativity is still alive….

Coaxial (joy-stick) rests allow both vertical and horizontal movement with a single control. If you want to make a diagonal shift in point of aim, you can do this with one, smooth, continuous movement. Until now, this advantage has been limited to front rests. Well there’s some new technology in the benchrest world. Forum member ‘Straightpipes’ has created a coaxial rear joystick rest. He built this simple, compact rear rest in his home workshop for use with his 40-lb Heavy Gun. In combination with a vertically adjustable front rest, this new rear joystick rest allows aiming to be controlled from the rear, with your left hand in a comfortable position.

Rear coaxial Rest Heavy gun

Straightpipes Rear Coaxial Rest — Design and Features
The rear rest is crafted from aluminum with a stainless steel forward-pointing joystick. Total weight, including the long, stabilizing base foot, is about 10 pounds. Though the rear rest doesn’t seem to have a large movement range, the system offers plenty of “on-target” travel. At 100 yards, the rest offers 10 MOA left, 10 MOA right, 5 MOA up, and 5 MOA down adjustment. That’s plenty of range for most targets, once you center the Point of Aim vertically using the captain’s wheel on the front rest, which Straightpipes also crafted himself. Click Square Photos Below to see Large Images.

Inside the rear cradle sits a Protektor rear sandbag, with Cordura fabric filled with ordinary sand. This fits the 3″-wide bottom of Straightpipes’ 40-lb heavy gun. There are some sophisticated components you can’t see in the photos. The rear rest can pivot (right or left slightly) to stay aligned with the front rest (as adjusted to level the cant of the rifle). Straightpipes says: “With the pivot, whatever I do to the front, the rear follows.” The basket (cradle) also employs a 20-lb bias spring system to handle the weight of the Heavy Gun. This prevents the co-axial system from binding, so it is fluid and easy to operate. Even with 20 pounds of gun weight on the rear, the joystick can be easily manipulated with a light touch of thumb and fore-finger.

Rear coaxial Rest Heavy gun

Video Shows Rear Coaxial Rest in Action
Watch the video below to see how the joystick controls the rear rest. Total joystick movement is about a 2.5″ sweep. This gives 20 MOA total windage adjustment at 100 yards, and about 10 MOA vertical.

About the Straightpipes Front Rest
The coaxial rear rest is designed to work with the massive front rest as a system, though they are NOT connected, so as to comply with IBS Heavy Gun rules. The 30-lb front rest supports exactly half the weight of the rifle and is used to set gross elevation. Windage and fine elevation is controlled in the rear. Straightpipes also designed and built his beefy front rest himself. As with his rear coaxial unit, the front rest pieces were all shaped by hand on a belt sander after being milled out. Straitpipes even “finish-sculpted some pieces with hand files the old craftsmen way.” The main center support column was milled with extremely fine threads. This allows the captain’s wheel to turn with little effort and no locking mechanism is required. Straightpipes does not need to fuss with locking knobs when he sets gross elevation. To help keep the unit from binding, there are stainless guide shafts on the left and right. These shafts slide in oil-impregnated bronze bushings.

Rear coaxial Rest Heavy gun

40-lb Barrel Block Heavy Gun with Savage Action
Straightpipes built this beautiful set of rests to work with his 40-lb Heavy Gun. Chambered in 7mm WSM, the gun features a Savage Target Action, and a Brux 32″, 1.300″ straight-diameter barrel fitted with a custom barrel nut. The barrel is clamped forward of the action in a 9″-long barrel block. This allows the Savage action to free-float. The block, also built by Straightpipes, looks fairly standard, but it has some clever design features. Between the barrel and the block there is sleeve that is slightly compressed when the block’s bolts are tensioned. This sleeve, made of a proprietary material, eliminates metal to metal contact between barrel and block. Straightpipes believes this enhances accuracy and provides some damping. Other shooters with barrel-block guns have used epoxy between block and barrel, but that makes disassembly difficult. The sleeve system on Straightpipes’ gun allows the barreled action to be easily removed from the stock. In addition, the compressed sleeve system is very stable — Straightpipes doesn’t have to fiddle with the bolt torques on his block.

‘Black Beauty’ Stock Made from Resin-Soaked Laminated Wood, with Rust-Oleum Finish
Straightpipes built the beefy stock himself. It is made from “red oak” wood soaked in resin and then laminated together with JB Weld. The rear section features a polished aluminum buttplate and twin metal “runners” on the underside, where the stock rides the Protektor Cordura bag. Straightpipes says the stock is very stable: “it absolutely does not flex or warp with changes in temp or humidity”. We asked Straightpipes about the stock finish. To our surprise, “Pipes” revealed he used inexpensive Rust-Oleum fine texture outdoor furniture paint. “Pipes” told us: “I’ve been using this stuff for years. It’s abrasion proof and tough as nails — the bags won’t wear it off. It’s solvent-proof, won’t get soft or bubble up. It cleans up with a damp cloth, just rub it down and it looks like new.”

Rear coaxial Rest Heavy gun

As designed and crafted by Straightpipes, this Heavy Gun rest system is impressive. The rear rest is brilliantly simple, and beautifully finished. But the important question is: “how does it shoot?”. Straightpipes reports that the whole system exceeds his expectations: “The rear rest actuation is smooth and positive. It works smoothly in conjunction with the front rest. Everything is working together — there’s nothing that’s fighting another element of the system. The gun tracks straight. When it returns to battery, the thing is pretty much waiting for you shot after shot.” The rear rest’s small footprint allows the “driver” to sit comfortably behind the rig. Straightpipes reports: “Shooters can ‘address the rifle’ just like a Light Gun — you’re not straining to wrap your arm around something overly massive. Anybody can shoot this, it’s a very easy gun to shoot.”

Is it accurate? In a word, “Yes”. Straightpipes doesn’t want to make claims before the rig has been tested in competition, but he says it has “shot groups at 600 and 1000 yards that would be very competitive.” We promised not to publish group sizes yet, but we can tell you that at 600 yards in good conditions it drilled some “scary small” 5-shot groups, well, well under 1/4 MOA.

Offset Heavy Gun Set Three IBS 1000-Yard Records in 2012

Report by Forum Member Ian S. (aka “Nightowl”)
After taking a few years off from competitive shooting, in 2012 Mike Gaizauskas returned to the long-range rifle scene in a big way. During the course of the Virginia 1000-Yard Benchrest Club’s 2012 season, Mike set three new IBS 1K multi-match Aggregate records. Mike broke into the record-books using a very unique 300 WSM rifle that incorporates a lot “brainstorming” and help from Mike’s friends and colleagues. The record-setting rifle features a super-wide forearm which is also offset. (As viewed from the shooter’s position, the stock is wider on the left, off-setting the barreled action to the right). This Heavy Gun has proven to be super-accurate — Mike barely missed setting a new IBS 10-shot-group HG record by a couple thousandths.

IBS 1000-Yard Records by Mike Gaizauskas:

  • IBS 1000-Yard Heavy Gun Ten-Match Group Aggregate (5.6664 inches)
  • IBS 1000-Yard Heavy Gun Ten-Match Score Aggregate (95.30)
  • IBS 1000-Yard Heavy Gun Six-Match Group Aggregate (4.4935 inches)

Missed a Fourth IBS Record by a Whisker (or Two…)
In 2012, Mike came “oh-so-close” to breaking the current IBS 1000-Yard Heavy Gun 10-shot small group record of 3.044”. Using his offset HG shown below, Mike drilled a 3.046″ 10-shot group, just two thousandths of an inch (.002″) off the current record. FYI, the thickness of a typical human hair is .001″ — you can’t get much closer than that!

The record-setting gun was built with components gathered over time, which were then fitted into a new ultra-wide stock. Mike ordered two custom stock blanks from Richards Micro-Fit Stocks of Sun Valley, CA roughed to Mike’s specifications. One was for a Light Gun, and the other was for a Heavy Gun. Mike had been thinking about an offset design for some time. During the 2007 Nationals held at the Virginia 1000-Yard Club, Mike just happened to sit next to Dave Tooley for a day. Mike and Dave discussed at length Dave’s experiences and conclusions regarding offset stocks. Dave explained that an asymmetrical or offset forearm is designed to counter the longitudinal torque that occurs when the gun is fired. You can find these concepts featured a few years back in the 6mmBR.com Blog.

In addition to tapping into the mind of Dave Tooley, there was a LOT of debate among Mike’s friends regarding what shape and which side of the stock would work best to counter the barrel torque generated when launching a bullet utilizing a right-hand twist. Should the stock be wider on the left or wider on the right? Mike eventually decided to widen the forearm on the left side and apparently that was a wise decision — just check out the trophies this big rig has already hauled in:

Heavy Gun Is a 300 WSM
This record-setting Heavy Gun was chambered in 300 WSM by Mark King. The gun features a BAT Model M action mated with a 30″, 1:10″ twist Krieger chambered to a .338 neck and finished off with a muzzle brake of Mark’s design. The barreled action is held with a clamp-style barrel block. The stock incorporates stainless steel rails fashioned by Mike’s friend and machinist Steve Reimers.

Stay tuned to the Daily Bulletin. We hope to provide a follow-up story with more photos and more information on Mike’s record-setting rifle (and the ultra-accurate ammo he feeds it).

Forum Member Builds DIY F-Class Rifle and Belt-Drive Rest

This story first appeared last year. We’re featuring it again by popular request.
Some of our mechanically-skilled readers chamber their own barrels or bed their own stocks. But these are relatively simple tasks compared to the jobs of constructing an entire rifle plus building an advanced front rest from scratch. Well that’s exactly what Forum member Steve B. (aka Essexboy) did. He built his own rifle and an impressive twin-belt-drive pedestal rest. (Click photo below to see large version). And get this, Steve’s home-made rifle was victorious in its first-ever match. Steve reports: “I shot my first Comp with the rifle this weekend and managed to win with a score of 239-21!” (The match was shot at 300/500/600/1000/1100 with English scoring of 5 points for center bullseye).

Do-It-Yourself F-Open Rig from England
Steve, who hails from Essex in the UK, constructed virtually every component of his skeleton-style rifle except the 28″ HV Bartlein barrel (chambered as a 6mm Dasher) and the Tikka 590 donor action. Steve also did all the design and fabrication work on his one-of-a-kind front rest. Steve tells us: “Over the last year or so, I made this rifle stock and rest. I managed to make it all on a little Myford Lathe, as you can tell I’m no machinist but it saved me a load of money — so far I’ve got about $200 invested plus the barrelled action. The stock is aluminum except for the stainless steel bag runner. The rifle came in at one ounce under weight limit for F-Class Open division.” Steve did get help with the chambering and barrel-fitting, but he hopes to do all the barrel work himself on his next project.

Tikka 590 Essex CustomThe gun is very accurate. Steve notes: “I have shot the rifle to 1100 yards and it shoots well. Last time out the rifle dropped just one point at 1000 yards and 5 points at 1100 yards [English scoring system]. I know it’s not pretty, but it got me shooting long range F-Class for peanuts.” Message to Steve: Don’t worry how it looks. As another Forum member observed: “Any rifle that shoots well at 1100 yards is beautiful….”

Steve started with a Tikka 590 action: “The whole stock was made on a small (6.5×13) lathe and a vertical slide. This caused a few head scratching moments, figuring out how to hold the T6/HE30 alloy for the milling/turning operations, but it did teach me a few things. The hardest parts were clamping the longer sections (such as the fore-end) and keeping it all square. Due to the short cross-slide travel I had to keep re-setting the parts. I managed to keep all measurements to .0001″ (one thousandth). I’m most proud of the trigger guard (photo below). This took a full day but came out really well, even if I say so myself.”

Belt-Driven Front Rest
We’re impressed with Steve’s ingenious front rest. Steve explains: “The rest is belt-driven and still in the experimental stage — hence no powder coating or polishing yet. I may have gone over the top as the key moving parts (the pulleys) run on three (3) types of bearings: radial; reamed bush; and a ball race. The main post runs on a radial bearing and the feet even have bearings in them, so when I raise the main body up (for rough height adjustment) the foot stays static.”

Will Steve build another rifle? Steve says he will, and he’s upgraded his tools: “Since building the rifle I have acquired a bigger lathe (Harrison m250) and a milling machine. For the next project I hope to be able to do the barrel work (threading, chambering, crowning) as well.” The next gun might be another Dasher. Steve explains: “After extensive reading on AccurateShooter.com, I chose the 6mm Dasher chambering, as I have a shoulder problem and can’t shoot a rifle with a lot of recoil.”
