Before embarking on this custom ELR rifle build, I turned to friend and rifle builder Doyle Anglin at Dixie Gunworks for input and advice. Doyle’s creativeness, attention to detail and rifle building knowledge are second to none! Our goal was to improve existing ELR rifle building techniques, and to create a drop-dead gorgeous masterpiece. To achieve this, we decided to supersize the .338 Lapua Improved barrel blocked rifle that shoots so well, into a 416 Barrett. I turned to BAT Machine for one of their fifty-caliber actions. Not wanting a common round receiver, I requested something unique that BAT had never done on any fifty-caliber action. My request was to multi-flat a two-inch diameter action. After some careful math, Bruce Thom of BAT Machine indicated that my request would be possible. Barrel blocks have been around a long time in both short range and long range benchrest. The advantages of a barrel block are greatly reduced cantilevered weight, increased system rigidity and harmonic dampening. Also, the barrel block removes all stress on the receiver threads as the receiver is free floating. This custom-made barrel block is drilled length wise to reduce weight. It incorporates an integral picatinny rail which is cross drilled to slightly reduce weight and add bling factor. The integral picatinny rail design facilitates mounting of optical offset devices such as the TacomHQ Charlie optical prism and Delta Tarac Unit, without the need to bridge mount. ?The Charlie unit allows for precise optical offset for distant shooting where significant elevation is required. This is a unique barrel block configured rifle and to my knowledge the only one currently being campaigned on the ELR circuit. Once others become aware of the advantages of barrel blocks, I suspect we will see more barrel blocks being utilized over time. Selecting the barrel manufacturer was easy. Again, I chose Krieger Barrels, one of the best barrel manufacturers on the planet. Doyle did a masterful job of designing and creating the integral railed barrel block to repose the massive Krieger barrel. It should be noted that this Krieger barrel is cut rifled. We chose a high gloss finish for the Krieger barrel, to match the, soon to be, high gloss clear finished stock. The barrel is capped with a Ryan Pierce five port magnum muzzle brake. Although a good design, I am not convinced the five-port magnum brake is large enough to effectively mitigate the recoil of 416 Barrett and 550gr bullet combination. I feel improvements can be made regarding muzzle brake effectiveness given comparative recoil testing vs. the Steyr HS-460. Extensive muzzle brake testing will ensue starting with the fine muzzle brakes from Kahntrol. Doyle Anglin is a master metalsmith and wood worker. Great wood artisans are few and far between. This custom stock is fabricated from the last remaining Obeche laminate stock blank in the “unicorn rare” Indian Blanket color scheme. This longer 48” stock provides better stability as the fulcrum point is extended. The stock is designed to provide maximum rigidity and harmonic dampening. It should be noted that the bolt rides under the cheekpiece. Not having to alter one’s head position, as the bolt is cycled, facilitates a better shot to shot shooting position and uniform cheek weld. Unlike other ELR stocks, it is possible to clean the barrel without having to drill through the butt plate assembly or the back portion of an offset stock. Also, note the integral, yet blind, trigger guard that can only be accessed through the right side. This design feature was not in the original discussions and Doyle surprised me. I like it! Knowing the fine folks at Cutting Edge Bullets, I turned to Dan Smitchko “Smitty” for my .416 caliber ELR bullet requirements. Cutting Edge Bullets are manufactured using precision CNC Swiss style lathes. This manufacturing method is the most accurate way to produce high precision turned parts. Cutting Edge Bullets have been used to win MANY ELR matches around the world as well as several King of 2 Miles competitions. Given the nine-twist barrel, I settled on running 550gr Lazers projectiles. ? The Barrett .416 brass is loaded with Vihtavuori 20n29 powder and uniformly ignited by RWS primers. Vihtavuori Powders are known for being very stable and producing consistent velocities throughout a wide operating temperature range. It should be noted that each firing cost approximately $6.55. The breakdown is as follows: bullet $3.05, powder $0.80, primer $0.50, cartridge case $1.00 (based on five firings), barrel wear $1.20 per shot based on 1000 rounds of barrel life. Hitting steel at distance: PRICELESS?. Atop the rifle sits a Sightron S3- 6-24x50 MOA second focal plane scope. Sightron has a long history of manufacturing high quality optics while providing the best value in class. Sightron is known for their optical clarity with class leading Zact-7 Revcoat Multi-coated glass. Additionally, Sightron scopes offer the patented ExacTrack which provides precise and repeatable tracking throughout the scopes range of movement. The Sightron S3 6-24x has 100 minutes of elevation and windage. Also, atop the rifle is the very well manufactured and repeatable Era-Tac 0-70moa adjustable scope mount. The advantage of using an adjustable scope mount or TacomHQ Charlie is they provide additional elevation for extended distance shooting. This can also be accomplished by utilizing tapered scope mounts, such as SPUHR, in conjunction with a tapered rail. Having increased elevation on tap allows the shooter to operate the scope closer to optical and mechanical center of axis when shooting at extended distances. Supporting the unlimited ELR rifle is the precision machined Duplin bipod. The bipod is attached to the forend via an Anschutz/Freeland style rail. The T-slot rail system allows for secure attachment of the bipod via two socket head cap screws. The Duplin bipod has a cant adjustment feature that is controlled via a tightening lever. The Duplin bipod was originally designed for F-class rifles under twenty pounds, however it works well with heavier rifles. Reloading equipment is comprised of the RCBS AmmoMaster press, RCBS 416 Barrett dies, RCBS 505 balance beam scale and Doug Giraud case trimmer with carbide cutter. In addition, I utilize a myriad of K&M expanders, measuring devices and tools to load the .416 Barrett. Cleaning efforts are supported by the fine products from Montana X-Treme. I utilize 56” 338-50caliber coated cleaning rods. The Montana X-Treme cleaning rods are manufactured from high strength spring steel and are coated with a non-embedding coating which protects the bore. Hopefully, Montana X-Treme will come out with longer rods to better support the long barreled ELR rifle platforms. A 72” cleaning rod would be a nice addition to their product offering. Most ELR competitors are shooting solid copper bullets and getting all the copper out is very important. I turn to Montana X-Treme Copper Killer for this task and have yet to find anything that removes copper as fast as Copper Killer. The Oehler Ballistics Explorer, Oehler 35P chronograph and Kestrel complete the puzzle. Oehler Research produces world class ballistic measuring devices and software. With correct inputs, the Oehler Ballistics Explorer generates precise firing solutions which incorporate spin drift, direction of fire, inclination/declination, latitude, Coriolis, etc. The Kestrel captures real time atmospheric conditions and provides necessary pressure, direction of fire, humidity, etc. The firing solution is only as good as the inputs, so capturing current, up to date, conditions is very important. The best ballistic software, meters and wiz bang devices will get you in the ballpark. Honing one’s wind reading skills will enable the shooter to further fine tune the firing solution. Having been the wind coach for many years of top ranked Highpower prone rifle teams such as ORSA (Oak Ridge Sportsmen’s Association) and NSSC (North State Shooting Club) I can attest that you can never out think Mother Nature! Going forward, my efforts will be focused on maximizing the performance of the factory Steyr HS-460 rifle and cartridge combination. I will be shooting a factory Steyr HS-460 this summer at various ELR matches and the King of 2 Miles. Additionally, a custom fast twist Steyr 460 is in the works to shoot 625-650 grain Cutting Edge projectiles. I feel the Steyr 460 offers the best balance of ballistics, barrel life, ability to see bullet trace and misses. I guess the adages “The gap between more and enough never shrinks” and “Enough is never Enough” still hold true. ................
