Victrix Armaments Rifles with Advanced 5-Axis CNC Technology

Victrix Italy Italian F-Class match rifles CNC Chambering

Report by Vince Bottomley
Victrix Armaments, an Italian company, has developed new technology that could be a major “game-changer” in the world of precision rifles in general, and F-Class in particular. Victrix’s leadership group knows all about excellence — and winning. Giuseppe Valtorta, CEO of Victrix Armaments, is a top competitive shooter who won Gold with his F-TR rifle at the 2015 European F-Class Championships.

A New Breed of F-Class Rifle
Turn back the clock half a century — George Farquharson is happily shooting a modified military rifle with iron sights and sling. He hasn’t even dreamt of F Class…

Benchrest however is beginning to gather momentum. Accuracy seekers are demanding the ultimate in precision engineering. They will go to their favorite gunsmith and, if they’re very lucky, procure one of the new custom actions from Hart or Shilen.

In the last 50 years, what’s changed? Benchrest is still with us but F-Class has emerged as a world discipline and, to some extent, brought new challenges to our accuracy rifle builders. But, whilst the rest of the planet has reveled in the speed and precision of CNC machining, we still love to place our faith in the gunsmith and his trusty old lathe!

Victrix Italy Italian F-Class match rifles CNC Chambering

But, of course, there is a reason for this. CNC equipment is expensive and geared towards the rapid multiple production of precision parts, whereas the custom gunsmith is dedicated to the ‘one-off’ build.

Also, even with a limited run, CNC does not readily lend itself to chambering our cut- or button-rifled barrels. Good as our barrels are, there are issues that have made CNC machine problematic. Each barrel demands loving care at the hands of our chosen gunsmith – if it is to perform to our expectations.

5-Axis CNC vs Manual Barrel Chambering
What if — What if the whole barrel-fitting and chambering process could be made “CNC compliant” and produce a rifle which would equal (or even exceed) the accepted standard. And do it every time, time after time! Cost could be reduced and also waiting times.

Good as our custom barrels are, they still need to be scrupulously checked — for uniformity of the bore, the lands, the grooves — for straightness, consistency of diameter, and concentricity. This could be achieved, using some pretty sophisticated measuring equipment — but that would be outside the realms of the custom gunsmith.

Even then, how could the barrel be easily accommodated in a CNC five-axis machining center to ensure a set-up for the best possible chamber and threading? Remember, bores are rarely concentric to the outside diameter and seldom straight, so the set-up would need to ensure that any deviation would be in the vertical plane when the barrel is screwed in the action and the chamber-section would need to be exactly aligned.

These are of course the issues faced every day by the custom gunsmith but currently, there are few CNC machines which could easily accommodate this requirement. But yes, there are a few….

Let me introduce you to Victrix, an Italian engineering company with an impressive multi-million euro factory crammed with the very latest in CNC machinery and a state of the art measuring laboratory. They already have a well-established background in the firearms manufacturing industry, at both military and sporting level. Never heard of Victrix? You soon will, for Victrix has chosen the prestigious 2016 IWA Show (Hall 9 – 423) to launch its new range of high-end rifles.

Victrix manufacturing facility in Italy is ‘crammed with the very latest in CNC machinery':
Victrix Italy Italian F-Class match rifles CNC Chambering

Whilst Victrix initially developed a range of tactical/military firearms — some of which will also be of interest to the sport shooter — the company has now turned its attention to the F-Class discipline. By working with those competing at the highest level of F-Class competition, Victrix has developed a range of “off the shelf” F-Class rifles that are “competition-ready” right out of the box. Incidentally, Victrix have chosen American barrel-maker Benchmark as its exclusive barrel supplier. Victrix has already perfected a way of accurately assessing barrels to adapt them to CNC working, and this is the key to the new project.

Victrix Target Trigger — Adjustable down to an Ounce
Victrix F-Class rifles will feature an advanced, new target trigger engineered by Victrix. This four-lever target trigger boasts an adjustment range of 1 to 2.5 ounces (30 – 70 grams). Another trigger (8 to 21 ounces pull weight), is used for the Victrix tactical rifles.

Victrix Action
For its new line of rifles, Victrix have developed its own proprietary actions. These actions employ some interesting ideas. The bolt is three-lug with a 60-degree lift and 105/105/150 degree lug-geometry. Testing verified that this arrangement provided a greater resistance to flexing in the locked position over the more traditional 120/120/120 geometry. This geometry also aids the pick-up and feeding of rounds from a magazine when used in a tactical configuration.

Victrix Italy Italian F-Class match rifles CNC Chambering

Above is Victrix’s new action. It’s impressive. Multiple configurations are offered: Right Bolt/Left Port, Right Bolt/Right Port and other variations. The action can be fitted with Victrix Target or Tactical trigger.

The action and bolt are machined from 17.4PH stainless steel and then hardened (body 48 Rockwell, bolt 45 Rockwell) and treated with PVD (physical vapor deposition). Finally the actions are coated with chromium nitride and nobium for wear-resistance and smooth operation. Tenon thread is M27x1.5 and of course, tolerances are ‘benchrest’ standard. Picatinny rails are screwed and pinned to the action.

Victrix has certainly done its homework. The company will offer rifles for both F-Open and F-TR classes. Stocks will be offered in a variety of materials: wood, wood-laminate, aluminum, and carbon-fiber. The stocks share a no-nonsense, straight-forward design, specifically for shooting a rested rifle.

Whilst we are focusing on their F-Class rifles, we shouldn’t forget the Victrix tactical range. Although designed with military and police use, they will appeal to anyone who enjoys tactical-style shooting. There is no compromise on quality or accuracy so, expect the same build standard but with stocks CNC’d from 7075 mil-spec aluminum with a hard-anodized coating. The Victrix three-lever tactical trigger adjusts from 8 to 21 ounces (250 – 600 grams).

Victrix has chosen March Scopes UK (IWA Hall 3A – 110) as its business partner in launching the new Victrix F-Class rifles. This was a wise choice, as March Scopes UK proprietor Gary Costello is a former World F-Class Champion. Gary, well-known to F-Class competitors, continues to shoot with the Great Britain Team.

We look forward to taking a closer look at the Victrix F-Class rifles and hope to provide an in-depth range report in the not-too-distant future. Check out the Victrix website at www.Victrixarmaments.com.

NEW PRODUCT: “Neuvo” Precision Action from BAT Machine

neuvo BAT Action Bullet Central Benchrest

An impressive new rifle action was just announced by BAT Machine and Bullet Central. This new action, dubbed the “Neuvo”, has many impressive features, and it certainly looks like nothing else on the market. Hall of Fame Shooter Dwight Scott provided design input for the Neuvo action.

Bullet Central says much careful design and engineering went into this new action: “The Neuvo … action is the result of more than half a century of experience in rifle building, gunsmithing, target shooting and high-end machining. Bullet Central, Dwight Scott, and BAT Machine teamed up to develop this receiver. The Neuvo encompasses time-proven functionality with a host of brand-new features. The new action includes a wide-body, two-lug bolt, horizontal locking lugs and a totally redesigned fire control system. The Neuvo is manufactured by BAT Machine in the U.S.A. and available at Bullet Central.”

After reviewing early photos of the BAT Neuvo action, Forum member Alex Wheeler liked what he saw: “This action has some features that do set it apart. A full-diameter two-lug will open very nice due to the shallower cocking ramp angle allowed by the large-diameter bolt. There is no lug raceway, so it [could be safer] in an over-pressure situation. I also think that full-diameter bolts run smoother due to not having lugs to bind. I hope to get to handle one of these to really look it over. The big thing will be the fire control — that will make or break it in my opinion.”

Go BIG: Wider Stocks for Mid-Range and Long-Range Benchrest

wide track benchrest stock

Most long-range benchrest stocks are three inches wide because that used to be the max width under the rules for Light Gun Class. Many folks may not realize that the IBS, the NBRSA, and the Williamsport organizations have all modified their Light Gun rules to allow wider forearm widths in registered 600-yard and 1000-yard competition. A wider stock provides increased stability and resists rotation (torquing) as the gun is fired. If you’re building a new Light Gun, you may want to consider a 4″-wide or 5″-wide forearm. Do check the rules of your local club or regional organization to ensure the wider width is allowed in the matches you attend. And if you plan to shoot F-Class as well, stick to 3″. Under F-Class (Open) rules, “the width of the rifle’s forend shall not exceed 76mm (approximately 3 inches)”.

Wider Forearm Stock Options
Most stock-makers still only offer a 3″-wide forearm width with their Light Gun long-range benchrest stocks. However, there are some other options. On request, Joel Russo, Russo Rifle Stocks, can cut a stock with 4″-wide forearm, but that’s not a standard pattern.

If you want a 4″-5″ wide version of the popular MBR Tooley-style long-range stock, Bill Shehane offers a ‘Big Dawg’ version of his MBR Tracker stock. This features a longer, deeper, and wider fore-end for added stability and more resistance to torque with the heavy calibers. Along with having a wider forearm, the Big Dawg stock is cut 4″ longer than a standard Shehane ST-1000 Tracker. This provides a “longer wheelbase” for better balance with very long (30″+) barrels. (The ST-1000 itself is 3″ longer than most benchrest stocks.) The Big Dawg is available with a 4″-wide or 5″-wide forearm, and will handle barrels up to 40″ in length and 1.5″ in diameter. In the top photo, taken by Forum member Preacher, you see a 4″-wide Big Dawg next to a normal ST-1000 Tracker. (Both stocks are symmetrical; there is distortion caused by wide-angle lens.)

wide track benchrest stock

This color pattern is what Bill calls “Prairie Dog Camo”, a Rutland laminate in orange and dark gray, with olive ‘accent’ layers. The price for a ‘Big Dawg’ in Rutland laminate is $625. In African Obeche wood (any color choice), the price is $855.00. For more info, contact Bill Shehane at (704) 824-7511, or visit his website, www.ScopeUsOut.com.

Wide Stocks for Rimfire Benchrest
Ultra-wide stocks are also legal in many rimfire benchrest disciplines. Shown below is a rimfire rifle built with a 4″-wide Shehane Big Dawg stock. This gun is used in ARA Unlimited competition. Extra-wide stocks like this can also be used in the IR 50/50 Unlimited Class and RBA Unlimited Class.

Why use a wide stock for rimfire where recoil is not an issue? The extra width definitely provides more stability in the bags. This is noticeable when cycling the action during the loading process — the gun shows less “wiggle” when opening and closing the bolt. The larger mass of wood also, potentially, provides additional vibration damping. A wider stock design carries more weight (per inch of length) and more mass is distributed outboard. Initial testing shows that the wide stocks work well for rimfire shooters who like to grip their gun — the gun feels “planted” with less wobble when the stock is gripped or cheeked by the shooter.

Wobbly Rings = WTF Accuracy

Reloading Rings Vu Pham Tactical

Vu Pham Rem 260Here’s a tale that should make you chuckle. This is the kind of boo-boo any shooter can make (but hopefully only once). Our friend Vu Pham from Sacramento was out testing his .260 Rem tactical rifle. Now Vu, an ace NorCal Tactical marksman, is a darn good shooter — but his first three-shot, 200-yard group looked like a shotgun pattern. Vu was puzzled to say the least. (His actual reaction, as noted on the target, was “WTF?!”)

But there was a simple explanation for the rifle’s miserable accuracy — Vu forgot to tighten the crossbolts attaching the rings to his scope rail. Consequently, his scope was moving after each shot. According to Vu, stunned disbelief followed by embarrassment happens “the moment you realized you forgot to torque your scope rings to the base after moving [the scope] the night before. [I felt like a] Freaking nooooob.”

5. (Nearly) Identical Duo. Here are a matching pair of customs from Forum member NHM16. He tells us: “I sold my two Savages I was using for F-Open, and had these two built in their place. One reason I upgraded was so I could have two (nearly) identical rifles. The nice thing about these rifles is that most everything interchanges, including the barrels.”

pride joy Savage .284 Walker Shehand Bartlein

Here Are Specs for Both Guns:
— Panda F-Class action (LRBP, no ejector, 20 MOA dovetail scope base, one action is polished, the other unpolished so I could easily tell them apart).
— PR&T LowBoy stocks with adjustable buttplates, with vents on the side and the bottom.
— Both have Bartlein 32″ 7mm, 1:8″-twist, 5R barrels, chambered in 7mm Walker (basically a .284 Shehane with the addition of a 40 degree shoulder).
— Rifles were built by Richard King (“Kings X” in Forum) in Arlington, Texas, though I did the clear coating myself.

6. First Custom. Here is Forum member Barrys’s very first custom rifle, and it’s a nice one. It features a BAT Machine VR action, Krieger #17 heavy varmint contour, chambered for the 6mmBR Norma with 0.272″ neck.

Primer Cratering Problem? Give Greg Tannel a Call…

Crater moon primers greg tannel bushing firing pinCraters may look interesting on the moon, but you don’t want to see them on your primers. Certain mechanical issues that cause primer craters can also cause primer piercing — a serious safety problem that needs to be addressed. If you have a gun that is cratering primers (even at moderate pressure levels), there is a solution that works with many rifles — send your bolt to Greg Tannel to have the firing pin hole bushed.

Shooters who convert factory actions to run 6BRs, 6PPCs or other high-pressure cartridges should consider having the firing pin bushed. These modern cartridges like to run at high pressures. When running stout loads, you can get cratering caused by primer flow around the firing pin hole in the bolt face. The reason is a little complicated, but basically the larger the hole, the less hydraulic pressure is required to crater the primer. A limited amount of cratering is normally not a big issue, but you can reduce the problem significantly by having a smith fit a bushing in the firing pin hole. In addition to reduced cratering, bushing the firing pin often produces more consistent ignition.

CLICK HERE for Gre-Tan Firing Pin Bushing Service INFO

This is a highly recommended procedure that our editors have had done to their own rifles. Greg Tannel (Gre-Tan Rifles) is an expert at this procedure, and he does excellent work on a wide variety of bolts. Current price for a bushing job, which includes turning the firing pin to .062″, is $80.00, or $88.00 with USPS Priority Mail return shipping.

If you have a factory rifle, a bushed firing pin is the way to go if you are shooting the high-pressure cartridges such as 6PPC, 6BR, 6-6.5×47 and 6.5×47. This is one of the most cost-effective and beneficial upgrades you can do to your factory rifle. For more info on the Firing Pin Bushing process, visit GreTanRifles.com, or email greg [at] gretanrifles.com. (After clicking the link for GreTanRifles.com, Click on “Services” > “Shop Services” > “Bolt Work”, and you’ll see a listing for “Bush Firing Pin Hole & Turn Pin”. Select “View Details”.)

Is “Stainless Steel” Really Rust-Proof?

Some folks feel that they don’t have to worry about rust and corrosion on stainless steel barrels, actions, and other components. That’s not really true. “Stainless” is a bit of a misnomer. First, there are different types of stainless steel alloys, with different degrees of rust resistance. 300 series stainless is more corrosion resistant than the 416 stainless commonly used in barrels. The composition (by percentage weight) of 416 stainless is 0.15% carbon, 12-14% chromium and the rest iron. 416 stainless steel lacks the roughly 10% nickel content that makes the 300 series more corrosion resistant in atmospheric conditions. But because 416 handles pressure better and is easier to machine (than 300 series steel), 416 stainless remains the better choice for barrels.

stainless steel barrel Techshooter

Though some grades of stainless are more corrosion-resistent, ALL varieties of stainless steel can rust if they are not handled and stored properly. Forum reader Kells81 observed: “Wanna see some rusted stainless? Go to the big “C” brand store in Ft. Worth. Every stainless gun they have on the used gun rack is rusted.” Tom Easly of TRE Custom explains: “Sweat is very corrosive. Sweat and blood will rust many stainless steels. I hate to handle my guns or drip on them when I sweat. It really helps to just wipe them good with a wet rag, dry and wipe on a light coating of gun oil. I think most stainless barrels are made from type 416 stainless, and it is generally pretty corrosion resistant, but not when exposed to sweat, blood, or chlorates (corrosive priming), and some other electrolytes.”

Forum member Jacob, who is studying materials science at LSU, provides this technical information: “The basic resistance of stainless steel occurs because of its ability to form a protective coating on the metal surface. This coating is a ‘passive’ film which resists further ‘oxidation’ or rusting. The formation of this film is instantaneous in an oxidizing atmosphere such as air, water, or other fluids that contain oxygen. Once the layer has formed, we say that the metal has become ‘passivated’ and the oxidation or ‘rusting’ rate will slow down to less than 0.002″ per year (0.05 mm per year).

Unlike aluminum or silver, this passive film is invisible in stainless steel. It’s created when oxygen combines with the chrome in the stainless to form chrome oxide which is more commonly called ‘ceramic’. This protective oxide or ceramic coating is common to most corrosion resistant materials.

Halogen salts, especially chlorides, easily penetrate this passive film and will allow corrosive attack to occur. The halogens are easy to recognize because they end in the letters ‘ine’. Listed in order of their activity they are: fluorine, chlorine, bromine, iodine, astatine.

These are the same chemicals that will penetrate Teflon and cause trouble with Teflon coated or encapsulated o-rings and/ or similar coated materials. Chlorides are one of the most common elements in nature and if that isn’t bad enough, they’re also soluble, active ions. These provide the basis for electrolytes. The presence of electrolytic solutions can accelerate corrosion or chemical attack.”

CONCLUSION: Stainless steel barrels and components won’t rust nearly as fast as blued steel, but you still have to take precautions — particularly removing sweat and corrosive salts from the barrel. Also, don’t let moisture build up inside or outside of the barrel. We recommend wiping your barrels and actions with Eezox, or Corrosion-X after each use. These are both extremely effective rust-fighters that go on thin, without leaving a greasy residue. (Eezox leaves a clear finish, while Corrosion-X has a slightly waxy finish.) Also store your guns in Bore-Store bags when the guns go in the safe. Bore-Stores wick away moisture, and the synthetic fleece inner surface is treated with rust-fighting chemicals. Bore-Stores also protect your guns against dings and scratches.

Corbin’s Curly Maple Masterpiece — .243 Win Prone Rifle

.243 Win 1000 yard Maple rifle

As a visual treat for our Daily Bulletin readers, we went back to our Gun of the Week archives to showcase a very special rifle. This humdinger could be the prettiest prone rifle we’ve ever seen. Commissioned for Forum member Corbin S., 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 barrel is a 30″ Broughton 5R Palma-contour tube, and there is another 30″ Broughton 6BR barrel that Corbin uses 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.

.243 Win Maple rifle

Very Accurate with Fast-Flyin’ Berger 105s
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. He 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.”
