Emil Kovan is one of the top F-Class shooters in the world. He won the 2014 United States F-Open Championship, and finished second in F-Open Division at the 2016 Canadian National F-Class Championship in Ontario. He is a great shooter and a great gun-builder as well.
“What are the best components for an F-Open class rifle, and why?” That’s a question that I get asked all the time and will try to answer in this article. Two months ago, I was contacted by Duane, a gentleman I met at the 2015 F-Class Nationals. He was interested in building a rifle with the new Master Class Low Profile F-Open Stock, created by Carl Bernosky and Alex Sitman of Master Class Stocks.
I have known Alex Sitman for many years, and use his stocks exclusively, but was not very familiar with his new Low Profile F-Open stock. After a brief conversation with Alex, I placed an order, and had the stock inletted and bedded at my shop in a month. My first impression was “Wow that’s a long stock” — the forearm is significantly longer than on the original Master Class F-Class prone stock. I bolted the barreled action in, and squeezed the end of the forearm and barrel together, the stock flexed a little bit, but not as much as other designs that I have tested. I think that’s due to having “more meat” in the receiver area. The full stock depth continues farther forward that on some other “low profile” designs. That makes the stock stiffer in the vertical plane, reducing the hinging effect forward of the action. The stock was finished in gloss black per the customer’s request. Interestingly, I found that the multiple layers of paint and clearcoat stiffened the stock up quite a bit.

Low Center of Gravity Tames Torque
Compared to the original Master Class F-Open stock, the barrel sits about an inch lower. Lower center of gravity equals less torque, and that is very important when shooting heavy bullets in fast twist barrels. Another significant improvement is that the toe of the stock is flat and parallel to the forearm. I added a 3/4″ track rail in the rear, and milled the underside of the fore-end to create two parallel “rails” in the front to help the stock track better.
One of the biggest reasons why I like Master Class stocks, is the pistol grip. I don’t shoot “free recoil” and a comfortable pistol grip is super important to me when selecting a stock. The new Master Class Low Profile stock shares the same grip as the old model. This allows the stock to accommodate either a “hard hold” style or a more free-recoil style of shooting — whatever the rifle’s owner prefers. This design versatility is one reason I recommend Master Class stocks. Shooters may experiment with either shooting style to find what suits them best.
Cartridge Choice — A 40° .284 Win Improved
Duane decided to have the barrel chambered for my 284 KMR IMP (Improved) wildcat. What is .284 KMR IMP and why choose it over the straight .284 Winchester? Improved by definition means “made better”, I took a great cartridge, and modified it to increase capacity, reduce pressure, and increase brass life.
There are many “improved” variants of the original .284 Winchester: 7mm Walker, .284 Shehane, .284 Ackley and so on. My version, the 284 KMR IMP, shares the .010″ blown-out sidewalls of the .284 Shehane, but I have further increased the case capacity by changing the shoulder angle from 35 to 40 degrees. The 284 KMR IMP allows you to almost match magnum cartridge velocity in a standard-bolt-face action. If you want to run 180gr-class 7mm bullets over 2900 FPS, it is cheaper and more convenient to have a barrel chambered in 284 KMR IMP than to spend $650 for a magnum bolt.
Tuning Loads for the .284 Win Improved Cartridges
The 284 KMR IMP seems to have two nodes, one around 2820 fps and other at 2940 fps. My match load clocks at 2935 fps with single-digit ES. Note –I selected that load based on accuracy, NOT raw speed. A lot of novice (or hard-headed) shooters make the mistake to push their cartridges to the max, and disregard more accurate loads at lower velocity.
The sport of F-Class is rapidly growing, and the equipment used is improving constantly. I remember that only few years ago, an F-Open rifle that could shoot sub-one-inch of vertical at 300 yards was considered competitive. Now, we are pursuing sub-one-inch vertical at 600 yards! It takes a great rifle to approach that goal, but it is also up to the shooter to learn and experiment as much as possible in order to achieve success.
Dies for an Improved .284 Win Cartridge
One of the biggest challenges in campaigning a wildcat cartridge has been obtaining great dies. When searching for custom dies, it almost seems like that the odds are stacked against us. The most common problem is wait-time — custom die orders can take months to be completed. Also, most custom die makers want you to send them two or three cases, each fire-formed three times. I find that funny because if could somehow properly size the cases for three fire-forming cycles, I would not need a sizing die.
Custom-made dies should size the case just right, but sometimes the die’s internal dimensions are slightly off, and this leads to problem number two: dies sizing too much (or even worse) too little. I had a one “custom” die that would not size the bottom of the case enough. This made the extraction of fired cases very difficult. I feel that the best option (if available) for shooters interested in wildcat chambers is to have their gunsmiths make the dies. I offer that die-making service in addition to barrel chambering.
BAT Machine “M” Action
Duane decided to use a BAT M action for this rifle, and I think that he could not have made a better choice. We are blessed with many good match-quality receivers: Barnard, BAT, Borden, Kelbly, Nesika, and Stiller just to mention a few. These are all very well-made and suitable for F-Class. Among BAT Machine Co.actions, I like BAT models M, MB, and 3LL best. I prefer these because because of their size (large bedding footprint) smoothness, timing, options available, and last but not least visual appearance.
Trigger: I recommend and use Jewell triggers. Other good options are: Kelbly, CG Jackson (good 2-Stage) Anschutz (best 2-Stage for Bat and Kelbly actions), Bix’N Andy, and David Tubb.
Barrel: Duane made another good choice here. He decided to go with a Brux 1:8.5″-twist, 4-groove cut-rifled barrel. If you look at the F-Class and Long Range benchrest equipment lists, you will see that cut-rifled barrels are currently dominating. Many records have been shot with both button-rifled, and cut-rifled barrels. I have shot both, and prefer cut-rifled barrels. I am not saying that button-rifled barrels are not capable of shooting as well as cut-rifled barrels, but on average, in my experience, four out of five cut-rifled barrels (from top makers) will shoot well, vs. three out of five buttoned barrels. YMMV, but this is what I’ve observed.
Scope: Duane’s rifle was fitted with a Nightforce 15-55x52mm Competition scope with DDR-2 reticle. This optic is ultra clear, reasonably lightweight (28 oz.), super reliable, and has 1/8 MOA clicks — what you want for long range F-Class competition. In this 15-55X NF model, I like the DDR-2 reticle best, because fine cross hairs (FCH) are hard to see in heavy mirage. The DDR-2 has a heavier horizontal line, with a center dot. March scopes are also very popular and very well-made.

The bar is raised yet again — the standards for long-range accuracy keep improving. Two talented Montana shooters have both gone sub-four inches for a 1K 10-Match Aggregate. What that means is that over TEN matches, these guys have averaged under 0.4 MOA at 1000 yards. Think about that. Most shooters will be happy with half-MOA at ONE HUNDRED yards. These guys are beating that by a significant margin at ONE THOUSAND yards, and they have done it for a whole season.
1000 Yard Multi-Match IBS Records Fall at Deep Creek
David Torgerson and Tom Mousel both broke the 10-match Light Gun Group Aggregate (Agg) record. Tom also broke the 6-Match Light Gun Group Agg record. Prior to these brilliant performances, the existing IBS 10-Match Agg record was 4.3155″. David crushed that with a 3.7946″, as did Tom with a 3.8734″. The existing IBS 6-Match Agg Record was 3.072″ and Tom shot a 2.954″, which will be a new record.
This is the first time in history that anyone has Agg’d in the threes for the 10-Match and in the twos for the 6-Match! For those not familiar with 1000-yard IBS matches, the Season Aggregate is based on ten matches. All ten are averaged for the 10-match Agg and the best six are averaged for the 6-Match Agg.
Shooters Established New Records with Multiple Guns and Multiple Barrels
David shot the majority of his targets with a Bat B action and Broughton 5C barrel. But he also shot his BAT SV and Borden BRM with Krieger and Lilja barrels. David’s 1K rifles feature Deep Creek Tracker stocks and March scopes. He shot Vapor Trail 103gr bullets in the all the rigs, and all his barrels are chambered in 6BRA — a 40° wildcat based on the 6mmBR Norma. The 6BRA retains the long neck of the parent case, but has more case capacity. Some people say the 6BRA is a bit easier to tune than the 6mm Dasher, but it still achieves that ultra-accurate 2920-2960 FPS velocity node.
Tom Mousel shot his 6- and 10-match Aggs with two rifles, splitting time between his BAT Neuvo LR and Borden BRM. Both are chambered in 6BRA and he shot multiple Krieger barrels. Tom told us: “Thanks everyone. David was pretty steady all year, while I took more of an up-and-down route. At one point early on I thought there’s no way this would be salvaged.”
The Neuvo-actioned gun (shown below) features a McMillan/Wheeler LRB stock, with a March scope on top. In that rifle, Tom shot 103gr Vapor Trails. Mousel’s Borden BRM gun features a Deep Creek Tracker stock and Sightron scope. In that 6BRA rifle he shot 103gr Roy Hunter bullets.

COMMENT by Alex Wheeler
If this doesn’t make you give up the idea you need that one hummer barrel to win I don’t know what will. Yes, you need the best equipment, but you also need the best tune and knowledge to stay on top of it. These two guys are some of the most dedicated tuners and testers I know. Well done! And well deserved!
It IS noteworthy that multiple rigs were used. Posting on Facebook, Alex H. said: “Holy ****! Tom did it not only with multiple barrels, but with two rifles AND multiple barrels? That is some outstanding performance! And Glenn K observed: “It was an awesome season to watch unfold. Congrats guys!”

In the benchrest game, both 100/200 yard disciplines and Long Range, it’s important that your rifle track smoothly and repeatably every time. You want the rifle to come straight back without twisting, rocking, or hopping on the bags. When you’re trying to drill your entire 5-Shot or 10-Shot string quickly, it’s also important that the gun returns to the same position after each shot. When the scope crosshairs return to virtually the exact point of aim, you can make successive shots with minimal aim adjustments.
For top “runners” who try to get five shots down-range in under 20 seconds, not having to make significant aiming corrections with your front rest controls can really speed up the process. Shooting quickly permits the competitor to “stay in the condition”, sending all his shots to the target before the wind direction or wind velocity changes.
TEN Shots in 20 Seconds at 1000-Yard Match
To see how rapid shooting works, watch this video of Tom Mosul, one of the USA’s best 1000-yard shooters. In a 10-shot Heavy Gun relay, Tom shoots his 17-lb Light Gun chambered for a 6mmBR Improved cartridge. He pulls the trigger for the first time at 00:20 and he fires his tenth (and last) shot at 00:40. Tom makes TEN SHOTS in 20 seconds, an average of just 2.0 seconds per shot!
TEN Shots in 31 Seconds at 1000-Yard Match
This second video, filmed from the side, shows Tom Mosel shooting a different 17-pounder. Again, note how smoothly the stock slides back and forth. Here Tom completes Ten Shots in 31 seconds, with the first shot at 00:13, and the tenth (last) at 00.44.
Adjustable Stock Rudder Through-the-Lens Video
Gunsmith Alex Wheeler sells stocks with an adjustable metal “rudder” or “keel” on the underside of the rear section of the stock. This rudder is the only part of the stock that contacts the rear bag. This aluminum rudder can adjust slightly left to right as well as adjust up/down for angle. Some guys want the keel nearly flat while others prefer the keel to be slightly lower in the rear.
This video shows how the cross-hairs stay on target once the stock rudder is adjusted properly. Alex adjusted this particular rudder by shimming the height* and moving the back of the rudder to the right.
The rudder’s horizontal adjustability allows benchrest shooters to correct for stock flaws that might adversely affect tracking. Essentially, by adjusting the rudder, you can achieve perfect alignment. Alex Wheeler explains: “If you pull your rifle back in the bags and the cross hair moves, your stock is not straight. The easiest fix is to use an adjustable rudder. They come standard on all my stocks.”
Wheeler explains: “The white box in the center of the 1000-yard target is four inches square. With a properly-adjusted rudder it’s easy to obtain less than one inch of cross-hair movement at 1000 yards.” You can see that, once Alex made the rudder adjustment, there’s hardly any detectable movement. Alex adds, “the more you play with it, the better you get it.”
*Initially Alex says he is going to shim the front. Later in the video Alex says he shimmed the rear. It can be a trial/error process. Credit Boyd Allen for finding these videos.

Looking 1000 yards downrange at the Deep Creek Range outside Missoula, Montana.
On Facebook recently, we saw an eye-catching rifle. Owned by top 1000-yard competitor (and past IBS Champ) Tom Mousel, this rifle was smithed by Alex Wheeler of Wheeler Accuracy. This rig features the McMillan-crafted Wheeler LRB stock with adjustable keel. It also has BAT Machine’s very impressive new Neuvo LR (aka “Neuvo M”) action, serial number LR0001. The Neuvo LR has some important design features — horizontal lug orientation, full-diameter bolt body, and advanced fire control system. More about those features below.
This gun is a shooter. Tom has already shot a 1.5″ four-shot group at 1000 yards. How does he do that? First you need a great barrel, great bullets, and superior hand-loading skills. But then it comes down to great gun-handling. You can see that in the video below. NOTE to ALL Long-Range Benchrest shooters — Watch this video! You’ll definitely learn from watching Tom shoot — he’s one of the best in the business.
Tom Mousel shoots 1000-yard ladder test with first-released Neuvo LR action, SN LR0001.
Rifle chambering is 6BR Ackley (6BRA) in 28″ Krieger barrel.
Rifle Components and Build INFO:
This rifle has a BAT Neuvo LR (aka Neuvo “M”) action glued and screwed into the LRB stock using a special bedding block, a Boyd Allen concept that Tom has requested to use on every future build. The 28″ Krieger 1:8″-twist HV barrel was indexed using a little different method than most use. It is “panning out well” says Alex, who adds: “So far it has shot [multiple low ones] with two barrels and three different bullet types. This rifle is definitely one of the better shooters I have seen.” We’d agree — owner Tom Mousel has had a 1.5″ 4-shot group at 1000 yards in testing, plus some “zero” 3-shot groups at 100 yards.
Chambering is the 6mmBR Ackley (6BRA). The stock is a Wheeler/McMillan LRB stock with vivid orange and black paint job. It features an adjustable keel in the rear. Trigger is a Bix N Andy unit from Bullets.com.
This BAT Neuvo LR action is a Left-loading Drop Port. Cartridges eject out the bottom of the action.
BAT Machine Neuvo Long Range “M” Action
This is the “Long Range” version of the BAT Neuvo. Dwight Scott and Chris Harris were the original inspiration. I worked with Chris to come up with a version for long range. The main differences for the LR Neuvo (compared to the shorter Neuvo) are this has integral lug and rail, with flat bottom and sides for better bedding. The BAT Neuvo LR is available in drop port, dual port, and single port as well as magnum.
Take a look at the bolt. Notice the lug orientation and full diameter bolt body. There are no bolt raceways in the action and the two lugs sit HORIZONTALLY when the bolt is closed — that’s different than the vast majority of other two-lug actions.
Alex Wheeler says the Neuvo is a winner. He thinks some of the action’s design features really do contribute to enhanced accuracy: “The … fire control (firing pin assembly) carries a lot of energy and has a very “clean” release. This is an excellent design with many small details that combine to deliver superior function. In addition, the full-diameter bolt can be fitted tighter than one with lugways. Also the horizontal lugs may be why we see less vertical stringing in the groups. They are timed perfectly as well.”

Above is a nice field rifle built up by a father for his daughter. Forum member FrankZ explains: “This is my favorite rifle and it will become my daughter’s first centerfire. The action is from the first rifle I purchased with my own money 21 years ago (700VSS).” The rifle now sports a 24″ Brux barrel chambered in 6mm Creedmoor, with aftermarket PT&G Bolt and DBM metal.
Here is a 6BR Ackley Improved built by Alex Wheeler. This blue marble-painted beauty features a BAT “B” action timed by Alex, fitted with Jewell trigger, and Borden trigger guard. The barrel is a Hawk Hill HV contour finished at 28 inches. The stock is a Deep Creek Tracker with 4″ forearm and rudder system (the toe of the stock adjusts for angle, allowing better tracking). This scope is a Vortex 15-60x52mm Golden Eagle riding in Burris Signature Zee rings.
Forum member Grimstod posted this nice 6BRX in a scenic setting: “Bill Goad at Premier Accuracy crated this fantastic 6BRX. It shoots better then I do.” The rifle features a single-feed Alpin action, with Hart 26″ 1:8″-twist barrel, chambered for the 6BRX (6mmBR wildcat) with .269 neck. Grimstod currently runs 95gr Berger VLDs in Lapua brass. On top is a Leupold 40x45mm scope on a Picatinny rail that Grimstod machined himself. The stock is an HS Precision painted by Premier Accuracy.
Here’s a gorgeous green 6mm Dasher. Forum Member Gunnermhr states: “This is my new 12-lb Dasher for the 1000 Yard Benchrest silhouette matches. My good friend at CRS Custom Rifle Stocks in Aaronsburg, PA made and painted the stock. It’s similar to a Tooley MBR with a few modifications. It still supported on a 3″ forearm and is full length. Hard to imagine it still makes weight with a wood stock and a 36 power Leopold. Crossed the scale at 11.7lbs. The rifle features a BAT “B” Action. The paint is Candy Apple Green, the forearm has a white base-coat, center section is gray base coat and the buttstock is black base coat, all covered with five coats of clear. It’s the new pride of the fleet as it shoots as good as it looks. This gun hammers with 105gr Berger Hybrids.”
Here’s a state-of-the-art Benchrest rifle, finished proudly in bright red. Forum Member JimmyMac posted: “Picked up my new 6 PPC today. This red rig features a Borden B action (Jewell trigger) fitted with a Lederer 1:14″-twist barrel with a Loker tuner. The barrel action rides in a Roy Hunter stock. On top is a Nightforce 42x44mm Competition scope in BAT rights. The rifle was smithed by Dave Bruno.
This impressive rifle features an “antique” 1917 Enfield action chambered for the .338 Win Magnum cartridge. The lovely Maple stock was hand-carved by Forum member Spitfire_ER. He tells us: “I found this piece of wood as a return at a lumber yard about 7-8 years ago. I asked the guy in the yard about it and he said it had been returned because it had too much figure for the job the customer was working on. First thing I thought was, ‘That would make a nice stock’.”
Not a Rifle But Still a Stunner…
Last but not least is one of the nicest stainless Ruger revolvers we’ve ever seen. Forum member Longcarbine says: “This is not a rifle, but it’s my favorite weapon”. The Ruger is fitted with a custom Picatinny scope rail with matching silver-tone Bushnell Trophy handgun scope, plus handsome faux Ivory grips. This wheelgun is almost too pretty to hunt with…

In this video, gunsmith Alex Wheeler explains how to ensure that your full-length sizing dies fit your brass properly. With many cartridge types, it’s not unusual for factory dies to be slightly large in the bottom section. When the diameter of a FL-sizing die is too large near the base, this can leave the bottom section of fired cases “unsized”, with the result that you can have extraction issues and stiff bolt lift, or what Alex calls “clickers”. At the same time, it’s not unusual for dies to over-size fired cases at the shoulder (i.e. reduce the shoulder diameter by .004″ or more).
We strongly recommend that all hand-loaders watch this video, particularly if you load cases 6+ times with relatively high-pressure loads.
Alex explains that a key dimension is the diameter of a fired case 0.200″ above the case head. If your die does not size your fired cases at this point, you should get a FL die that does. This could be a custom die ground to fit your chamber, or it could be a “small-base” die specifically designed to “hit” the bottom section of the case. Alex also notes that some FL dies have an inside chamfer at the mouth of the die, right at the very bottom. (See video at 3:55). This can leave the section of the case right above the extractor groove unsized, which can also lead to “clickers” and stiff bolt lift.
Paint Your Brass to Find Problem Areas
If you are having stiff bolt lift or extraction issues, Alex explains that you can “paint” your brass with magic marker (or dye-chem), and then place the case in your chamber. On the “hot spots” where the case contacts the chamber wall, the marking will rub off, allowing the brass metal to shine through in the problem area(s). This will illustrate where you need better sizing from your die.
“You can ink up the case with some magic marker or dye-chem. If you are getting clickers, go ahead and mark up the case and chamber it and see where it’s wearing. This will help you diagnose [whether the problem] is coming from the base, is it coming maybe from a score in the chamber… it can even happen at the shoulder although that’s pretty rare. Usually the dies size enough at that point.”

Kelbly makes outstanding actions, including the Stolle Pandas. In the past 20 years, Pandas have probably won more benchrest matches than any other action (though BATs and Bordens are increasingly in the winning circle). Recently gunsmith Alex Wheeler of Wheeler Accuracy worked his magic on an aluminum Panda, optimizing the “ignition timing” of the action. This involves many small mods to bolt, camming surfaces, trigger, and firing pin: “The whole cam helix and detent shelf is re-cut. The firing pin and cocking piece are modified as well.” When executed properly, Ignition Timing has a number of benefits, including a smoother bolt opening/closing, improved firing pin fall, and enhanced accuracy (though the accuracy improvements can be subtle).
BEFORE Action Timing — Stiff and Clunky
Alex reports: “Normally Panda actions have plenty of firing pin fall. For one reason or another this one was very low. Before timing, firing pin fall was .210 with a Bix’N Andy (BNA) trigger. After trigger timing firing pin fall is .244 with zero cock on close.” Here is how the action functioned before timing work:
CLICK Photo to start VIDEO
Alex notes: “As you can see, after the cocking piece rides out of the detent notch it thenfalls to the trigger and is then re-cocked. This is normal on most un-timed actions.”
AFTER Action Timing — Smooth and Refined
Alex explains the modifications he made for this Panda action: “Moving the trigger back adds cock on close. The whole cam helix and detent shelf is re-cut. The firing pin and cocking piece are modified as well. I do love a timed Panda. In fact, I like aluminum actions, I think there is something to them. But yes, I also recommend Borden as my first choice.’

Fix for Right-Bolt Actions Only
After seeing these videos on Facebook, one poster asked: “I do like my Panda but this is exactly why I bought a Borden action and I love it. It’s good to know you can make a Panda better. Alex, can you time a left bolt Panda?”

Gunsmith/stockmaker Alex Wheeler is a very smart guy. Among his many clever innovations is an adjustable bag-rider that fits on the underside of the buttstock at the rear. Alex calls this a “Rudder” because it allows the shooter to align the tracking perfectly. The rudder assembly can swing left and right using an adjustment bolt. You can also adjust the Rudder’s vertical “angle of attack” with simple shims. Some guys like the Rudder’s 3/4″-wide bottom perfectly parallel with the bore axis. Others prefer a slight angle so the stock slides down a bit during recoil.
Adjustable Rudders Now For Sale
Alex has fitted these innovative, adjustable Rudders in the stocks and complete rifles he sells.And now owners of other stocks can benefit from Wheeler’s invention. Alex is offering the Rudders for sale: “I have made my adjustable Rudders for sale. Price including mounting hardware is $125 shipped. These are the same rudders I install in most ever stock I build. They’re the only way to achieve perfect tracking every time.”
Watch how the Wheeler Rudder works in this video. Alex explains: “If you pull your rifle back in the bags and the cross-hair moves, your stock is not straight. The easiest fix is to use an adjustable Rudder. They come standard on all my stocks. The white box on the 1000-yard target is 4″. With a properly-adjusted rudder it’s easy to obtain less than 1″ of cross-hair movement at 1000 yards.”
Rudder-Equipped Stock In Action (with 1000-Yard Champ Tom Mousel)
This second video shows how well a Rudder-equipped stock performs. This shows IBS 1000-yard Champ Tom Mousel running five (5) shots with his 17-lb Light Gun chambered in 6BR Ackley Improved. Note how perfectly the stock tracks. It runs smoothly straight back then comes right back on target when pushed forward by Mousel. Check it out — this is impressive.
It’s relatively easy to install these rudders on most wood and wood laminate stocks. Alex says: “Just notch the stock, and install the anchors for the adjustment bolts.” In addition, McMillan will soon be offering fiberglass stocks with a notch designed to fit the Wheeler rudder. Based on Alex’s Deep Creek Tracker stock design, these new McMillan stocks with have metals rails in the front also.
New Rudder-Equipped McMillan LRB Stock
Alex explains: “The new McMillan Rudder-equipped stock will be a version of the Deep Creek Tracker, most likely called a Wheeler LRB (Long Range Benchrest). It will feature factory installed 1/2″ wide aluminum rails in the 4″ fore-arm. It will come with the rear notch molded in for the Rudders which I will install on each stock. I will be exclusive dealer on these and hope to see the first one in June. I also have got with Edgewood to make 4″ wide front bags that will fit a standard rest top and will cost the same as their standard 3″ bag. I will have some in stock but anyone can order them direct and not have to pay the $125 price for a custom bag.”

Even with a bit of snow left on the ground, some great long range shooting took place up in Montana recently. March 25th, 2017 was opening day for the first 1000-yard IBS match of the year at Montana’s Deep Creek Shooting Range, just outside of Missoula, Montana. With temperatures during both matches at a consistent low to mid 40s and winds blowing at a slight 2-4 mph from the south, the weekend was sure to produce some excellent results.
Framed by forested hills, the Deep Creek Range is a beautiful place to shoot.
Fifteen (15) shooters braved the cool Montana spring weather for what would turn out to be a very competitive match. On Saturday, both Richard Schatz and David Torgerson made the first Light Gun (LG) shoot-off, posting two-inch groups, with Richard taking the win (check out his targets above). David and Richard made it into the Heavy Gun (HG) shoot-off as well, this time with David taking the win. Leo Anderson took the LG score crown with a 47, while Shawn Williams took the HG title with a perfect 100.
Here Scott Stanko sets up his Light Gun. Scott won Sunday’s LG shoot-off.
Sunday’s conditions were even better and the shooters took advantage of them. Once again, some truly excellent groups were shot by Tom Mousel and Scott Stanko, both making the LG shoot-off with 2 inch groups. Scott, shown above, prevailed in the shoot-off. Richard Schatz, once again, made his way into the shoot-offs and took the HG win from Tom Mousel with a 4.889″. Jeff Reed took the HG score win over Leo Anderson with a 96. In the LG Score shoot-off, Jim Williams nailed a real stunner of a group, taking the Score win with a 2.018” – 49. Check out the group below. That sure would have helped his Aggs if it happened in the relay!
Jim Williams with his 2.018″- 49 group. That works out to 0.19 MOA — amazing accuracy at 1000 yards.
New Cartridge Debuts — the 6mmBR Ackley Improved (6mm BRA)
The 2017 season has brought some new gear/cartridge developments and many shooters were able to put them to good use in the first match of the year at Deep Creek. Leo Anderson and Tom Mousel were both shooting the new 6mm BRA (6mmBR AI), a 6mmBR Norma with a reduced body taper and a 40 degree (40°) shoulder. Fire-forming is as simple as turning the necks and shooting, as the factory 6mmBR case will headspace in the AI chamber. Sizing with a 6mm Dasher die with .080″ turned off the bottom is the ticket. Tom Mousel, reigning IBS 1K Champ, “believes this case to have a little wider tune window and far less throat wear”. That means this case might be easier on barrels. For Tom’s 6mm BRA with 28” Krieger barrel, the accuracy node is about 2980-2990 fps, so this gives up only 30-50 fps compared to typical Dasher velocities. Both of Tom’s HG groups held in the 3s for vertical, proving the 6mmBR Ackley’s accuracy potential.
Vapor Trail Bullets and Deep Creek Tracker Stock
Tom Jacobs at Vapor Trail Bullets has been working with a new die for his excellent 6mm 103gr Vapor Trail bullet. Four of the weekend’s competitors were shooting bullets off the new Vapor Trail die. The new die seems to be producing a bullet every bit as good as the old die, maybe even better. Several groups in the 2s (two inch) were shot this weekend. As well as Richard Shatz’s impressive 3.671″ 10-shot group in Heavy Gun (see top of this article).
Finally, the new Deep Creek Tracker 4″-wide stock is becoming a favored option, with half of the competitors at the match shooting these stocks from Wheeler Accuracy. That extra inch in the stock’s fore-end seems to be provide more stability and less rocking on the front rest when opening and closing the bolt. Also, the adjustable tracking rudder makes for perfectly parallel tracking surfaces, an absolute “must have”.
The weekend ended with the sun finally breaking through the clouds. Competitors enjoyed some great grilled Polish dogs with all the fixings prepared by Mark and Angie Candau; who also shot in the match. There were plenty of smiling shooters with awards/prizes for their efforts. It was a great opening match of the season!
Here are the Top Guns at the match: Dave Torgeson, Jim Williams, Jeff Read, Shawn Williams, Richard Schatz, Leo Anderson, Lonnie Anderson, and Tom Mousel.
Deep Creek is one of America’s best 1000-yard shooting centers — many records have been set here.
