Sunday GunDay: 1000-Yard Prone Rifle — Corbin’s “Maple Marvel”

.243 Win 1000 yard Maple rifle

“I have molested that rifle on several different occasions over the years. It is more beautiful in person if that is possible. Fine craftsmanship in every aspect.” — Forum Member Matt K.

.243 Win prone rifle Corbin ShellToday’s Sunday GunDay feature is a “blast from the past”, part of our big Guns of the Week archive. Some years back, Forum member Corbin Shell told us he had a new, full-custom 1000-yard prone rifle. When he sent some photos of the maple-stocked masterpiece, our collective jaws dropped. Check it out — this is truly a “Maple Marvel”.

.243 Win 1000 yard Maple rifle

Corbin’s GunDay rig is an eye-catcher for sure. This is one handsome rifle, built with all-premium components and a stunning Curly Maple thumbhole stock with adjustable cheekpiece. The rifle is chambered in .243 Winchester. It features a custom stainless RBRP action Nesika R action, with keycuts in the bottom instead of recoil lug. A Grünig & Elmiger trigger has been specially modified (milled and pinned) to work with the Nesika action. The primary barrel is a 30″ Broughton 5R Palma-contour tube. Interestingly, Corbin has a second 30″ Broughton barrel chambered in 6mmBR for use at shorter ranges.

The trigger guard, fore-arm rail, cheek adjuster, and 4-way adjustable butt assembly are all custom metal, designed by Dan Gleason. The stock is cut from exhibition-grade fiddleback maple (from Cecil Fredi Gunstocks in Las Vegas) with a Gaboon Ebony tip wood and butt-plate spacer.

Fast and Accurate
Corbin tells us the gun will put five shots into the size of a quarter at 300 yards “when he does his part.” Corbin shoots pointed Berger 105gr VLDs and 45.5 grains of H4831SC. That load runs 3180 fps. He can push it faster, but “that’s where the node was and where it shoots best”, according to Corbin.

Forum member Jim Hardy has seen (and shot against) this beautiful rifle. Jim reports: “A casual observer might think that the trigger guard, cheek plate and butt plate hardware are Anschutz — as the stock takes on the Anschutz prone pattern. However, this is ALL custom metal. The G&E trigger breaks like a glass rod and will makes my BR triggers feel inferior at best. I had the pleasure of holding, shouldering, and lusting over this gun at Camp Perry last year, and it is even more impressive in person. The killer is that there is yet ANOTHER one in a beautiful, dark figured walnut owned by Corbin’s shooting partner. BTW, both guns will hammer at 1000 yards prone.”

Long Range Prone Shooting with the .243 Winchester
Is the .243 Winchester capable at 1000 yards? Absolutely. John Whidden has used the .243 Win to capture multiple NRA National Long-Range Championships. John selected the .243 Win because it offers excellent ballistics with manageable recoil. John says that, at least for a sling shooter, the .243 Win is hard to beat at long range. John explains that, while you CAN get somewhat better ballistics with a .284 Win or .300 WSM, you’ll pay a heavy price in increased recoil with those bigger cartridges.

Running at an impressive 3275 FPS from his .243 Win, Berger 6mm 105 grain Hybrids are hard to beat, according to Whidden: “My .243 Win shoots inside a 6.5-284 with 142-grainers. Nothing out there is really ahead of [the .243], in 1000-yard ballistics unless you get into the short magnums or .284s and those carry a very significant recoil penalty.” John has tried bigger cases: “In the past I did shoot the 6.5-284. I went to the .243 Win because it had similar ballistics but had much less recoil. It doesn’t beat me up as much and is not as fatiguing.” READ Whidden .243 Winchester Report.

Sunday GunDay: Corbin Shell’s ELR Record-Setting .416 Barrett

ELR Central Extreme Long Range Record Cold Bore Corbin Shell Georgia Krieger BAT Dixie Gunworks Sightron

Today’s Sunday GunDay story features Corbin Shell’s remarkable, record-setting .416 Barrett. With a 40″ Krieger barrel secured in a massive barrel block, this is definitely a big boomer!

ELR Central Extreme Long Range Record Cold Bore Corbin Shell Georgia Krieger BAT Dixie Gunworks Sightron

Last month, Forum member Corbin Shell set a new Extreme Long Range (ELR) record. With no sighters or warm-up shots, Corbin put three (3) shots on a 36″ x 36″ steel plate at 2118 yards, establishing a new Cold Bore ELR World Record. The range was verified with three rangefinders and witnessed by 20+ awestruck shooters. Applied Ballistics reports: “There is a new official ELR World Record. 2118 yards. 3 for 3 cold bore.” This was also recognized as a record by the FCSA (Fifty Caliber Shooting Association).*

ELR Ain’t Cheap — $6.55 Cost per Shot
Corbin told us: “Each round fired 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!”

If you want to learn more about this record-setting rifle, Corbin has prepared a 6-page project history describing all the components and explaining how the rifle was constructed. This Build Document also contains a wealth of information about loading for the .416 Barrett cartridge.

Conditions During Record:
Corbin tells us: “This was shot in Blakely, Georgia at the Arena Training Facility in good Ole dense Southern air. Here are the atmospheric conditions when I shot: 70 degree temperature, 29.70-29.80 inches of mercury, 82% humidity, 1211 Density Altitude (DA).”

Corbin noted that the unique barrel block with rail helps with ELR Optics: “This custom-made barrel block is drilled length wise to reduce weight. It incorporates an integral Picatinny rail which… facilitates mounting of … the Tacom Charlie/Delta TARAC prism system, without the need to bridge mount.” Charlie/Delta TARAC units effectively offset the view that comes into the scope, providing up to 625 MOA elevation.

ELR Cold Bore Shot Record Rules
Congratulations to the new ELR World Record Holder Corbin Shell. The record now stands at 2118 yards. This record was shot under a very specific set of rules established by ELR Central and industry leaders. For more ELR record information, go to ELRCentral.com. All ELR World Record results can be seen on the ELR Central’sEvent Results Page.


* Prior to Corbin Shell’s GA record, David Tubb shot a 2200-yard, 3-shot group that has been recognized as a FCSA record. However, because David had made a same-day attempt, within minutes, with a different rifle, this did not comply with the ELR Central Rules. So, at this time only Corbin Shell is recognized as the ELR Central World Record Holder.

.338 Lapua Magnum Improved Barrel Block Beast for K02M

.338 Lapua Magnum Improved KO2M David Tubb Corbin Shell Tall Target

Report by Corbin Shell
Not long ago, I learned of the King of 2 Miles (KO2M) shoot held in Raton, NM and was fortunate enough to get an entry slot. I will be shooting with David Tubb, multi-time High Power and Long Range National Champion, on a team we call the “Second Amendment Cowboys”. Given such short notice, I scrambled to find the necessary components to build a suitable rifle for the event. I turned to longtime friend and owner of X-Treme Shooting Products (XTSP), Tom Myers, to see if he might have a suitable action. XTSP is known for its premium titanium rifle receivers, however XTSP also manufactures stainless actions. As luck would have it, Tom was completing a small run of .338 Lapua Magnum-sized stainless steel single-shot actions. Other components were sourced as quickly as possible and the building began in earnest.

Before acquiring the first component for this build I already knew who was going to perform the work, Doyle Anglin at Dixie Guns, inc.. Doyle’s attention to detail and rifle building knowledge is second to none! I came to Doyle with the idea of building a rifle to shoot in the King of 2 Miles match and his ears perked up. Once all the components were in hand Doyle began construction. Doyle was given free liberty to build whatever he felt best for the job given the time constraints and components that were readily available on such short notice. I cannot thank Doyle Anglin enough for the stellar job he did!

Given the 12-pound barrel weight, Doyle strongly suggested a barrel block to offer additional support and increase rigidity. Doyle created a split ten-inch aluminum barrel block and mating steel plate that is inletted into the forend of the custom laminated stock. The 1:9.3″-twist Krieger barrel is epoxied into the barrel block as well as being held in place by the ten socket head cap screws. Two hardened and ground pins locate and index the barrel block onto the steel mating plate. The steel mating plate acts as the recoil lug which mates up to the cut on the reward section of the barrel block. The Krieger barrel is chambered with a 30-degree Lapua Magnum Improved reamer and throated accordingly, yielding a loaded round of approximately 4.000 inches.

The barrel is capped with a very effective Piercision Rifles 3/4×24 slab-sided, five port muzzle brake. The size proportions of the muzzle brake work well with the 1.100” muzzle diameter, however it will work on barrels up to 1.450″ in diameter.

Doyle Anglin worked his creative magic and constructed the multi-color laminated stock from a blank. The five inch fore-end allows the rifle to be utilized in a dual role — either benchrest or prone with bipod. The cheek piece hardware is from Master Class Stocks and is adjustable for cast on/off with preset elevation settings via half-moon shaped clips. The two-way adjustable butt plate hardware also comes from Alex Sitman at Master Class Stocks. The multi-colored laminate stock is clear-coated with special marine UV inhibitor paint. The glass smooth finish makes the wood appear wet and is extremely smooth to the touch.

Lots of Elevation on Tap with Angled Rails, Spuhr and Ivey Mounts
Topping off the rifle is either a +35 or +60 MOA X-Treme Shooting Products Picatinny scope rail. The receiver and scope rails are pinned for accurate repeatability when interchanging. Five 8×40 socket head cap screws firmly hold the scope rail in place. A SPUHR +20.6 MOA tapered, one-piece scope mount securely grasps the Sightron SIII 6-24x50mm MOA scope. I cannot say enough good things about the quality of the SPUHR scope mount! This is the only fixed scope mount that I will use going forward and a special thanks goes out to Ulf at SPUHR! The 35 MOA rail and 20.6 MOA SPUHR mount setup allows full utilization of the Sightron’s 100 MOA of internal travel. The second scope setup is comprised of an Ivey +175 MOA adjustable scope base and Sightron SIII 6-24x50mm optic.

Scope in IVEY Mount with barrel block-mounted precision bubble level:
.338 Lapua Magnum Improved KO2M David Tubb Corbin Shell Tall Target

When shooting extended long range (ELR) it is important that the scope’s crosshairs remains level. Should the crosshairs be canted it will induce impact shift which increases with the angle of cant and distance. The decision was made not to use any of the lesser quality/precision bubble levels that currently flood the market. These levels have poor resolution usually between one and two and a half (1-2.5) degrees. It must be noted that not all levels are created equal. The fine folks at Geier & Bluhm offered up a solution with a precision glass vial horizontal level with an accuracy of ten minutes. As a refresher, one degree is comprised of 60 minutes of angle. The level setup we chose for this rifle is, at minimum, six times more accurate than the best scope or picatinny level on the market. The 10 MOA bubble level sensitivity is just about perfect and does not create a situation of having to “chase” the bubble left and right when in position.

A portable 150 MOA tall target was created to test both scope tracking and crosshair alignment. When testing at the local 100-yard range I got a lot of strange looks and a few inquiries as to why in the world was I shooting thirteen FEET above the aiming bullseye.

As the F-TR shooters have learned, it is very important that the rifle travel freely and repeatable under recoil. I turned to Ray Gross who custom made a rubber and Cordura shooting mat which the bipod rides on. This mat is of the same material and construction that most of the F-TR team is utilizing. The rubber durometer is correct so the rifle does not bounce or hop when fired. The bipod skis slide very easy on the Cordura-topped mat. A big thanks goes to Ray Gross for assisting with the mat setup. In addition, high molecular weight polyethylene (HMWPE) tape was applied to the butt stock of the rifle. The HMWPE tape allows for extremely low friction between the butt stock and rear sand bag. This configuration tracks very well and slides rearward like it is on rails.

As load development progressed I tested three different brands of projectiles. A ladder test was performed at 300 yards to determine where the node was with my barrel and powder combination. The rifle liked between 99-101 grains of Hodgdon Retumbo. I then proceeded to shooting ten shot groups at 1000 yards. In this rifle the Sierra 300gr Matchking was hands down the winner for smallest groups and the best elevation at 1000 yards. The load settled on is 101 grains of Retumbo and 300 grain Sierra Matchking. 500 Sierra bullets were measured base to ogive and the spread over the entire 500pc measured .003” with 490pc varying by .001”. Keep up the good work Sierra Bullets! A special thank you goes to John Whidden for generously allowing me to come to his shop and repoint the Sierra .338 projectiles and allowing me to test at his 1000 yard range.

Preparation for the King of 2 Miles match has been a great learning experience and a lot of fun! Next year’s rifle design is already in the works and should be an over the top build. Stay tuned to AccurateShooter.com for further details!


* The Sierra 300gr MatchKings were meplat-trimmed and pointed using the original pointing system made by Ferris Pendell for Jim Hardy. A big thank you goes out to John Whidden for allowing me to come to his shop and use the original bullet pointing system.
