Sunday GunDay: Vudoo Gun Works V-22 Rimfire Rifle

Vudoo Gun works V-22 rimfire .22 LR rifle

This Sunday GunDay story features a .22 LR rifle built around a Vudoo Gun Works V-22 rimfire repeater action. The V-22 action, arguably one of the best tactical rimfire actions available, owes its lineage to the respected Remington 40X action. Many rimfire matches have been won with 40X actions, so we understand why Vudoo chose that design for a starting point. Vudoo then added some important enhancements, including a controlled-feed design. This makes the Vudoo a great choice for rimfire cross-training, rimfire tactical matches, and NRL22 competition. In the video below you can see the Vudoo Gun Works rifle used an a PRS-style, long-range precision rimfire match in Minnesota.

As it has the same footprint as a Remington 700, the Vudoo Gun Works V-22 action is 100% compatible with a wide variety of Rem 700 chassis, triggers, and rifle accessories. This allows you to have a rimfire trainer with near-identical ergonomics as a centerfire match rifle. Rimfire training provides valuable trigger time with dramatically lower ammo costs. Along with actions, Vudoo sells barreled actions, and complete rifles through its website: VudooGunworks.com.

In this video, Dave Timm of GunsandTactics.com employs a Vudoo V-22 in the Minnesota .22 LR Long Range Precision Rimfire Match at the Rush Lake Range. This PRS-style match had targets out to 300 yards during the main match, followed by a long range challenge out to 465 yards. Dave’s Vudoo Gunworks V-22 rifle features a Grayboe Ridgeback stock, Harris bipod, and Trijicon Accupower 4.5-30x56mm FFP scope. Dave was shooting Lapua Center-X .22 LR ammunition.

This course of fire was challenging. Dave explains: “Stages included barricades and barrels and props to shoot out to targets at 100, 169, and 214 yards. So we’re shooting a 6″ piece of steel at 214 yards with an awkward position and a .22! It’s a good challenge and it really forced you to get all your fundamentals together. You’d be surprised at how much movement [there is]. You feel that you’re steady but all of a sudden that reticle just doesn’t want to stop moving.”

This Minnesota Match is similar to a PRS-style competition, but for rimfire rigs. Dave said “This match was an absolute blast and pushed out the .22 LR round out to some distance.”

About the V-22 Action — Controlled-Feed Design

Vudoo Gun Works states: “Our V-22 runs a full-size short action bottom metal (DBM) and our V-2210 magazine has a [full-size] AICS form factor. The V-22 is the only controlled-round-feed .22 LR receiver out there. The bolt has full capture control of the cartridge from the time it leaves the magazine until it ejects the spent round out the ejection port. That means the round never touches anything during feed travel so the bullets won’t be nicked/dented during rapid cycling.”

V-22 Product Description from Vudoo Gun Works:
The V-22 has been designed from the ground up as a true-to-scale Rimfire receiver that fits the Rem 700 footprint [for] stocks and chassis[.]. It also runs a full size short action bottom metal (DBM) and our V-2210 magazine has an AICS form factor[.]

The V-22 has a very unique control-round-feed protocol. The bolt has full-capture control of the cartridge from the time it leaves the magazine until it ejects the spent round out the ejection port. The significance of that is two-fold. Great feed and extraction reliability and…equally as important, the cartridge is controlled in a way that it never touches anything on its entrance into the bore. There is no feed ramp, nor does the projectile go in at an angle that would damage it in any way. We all know how susceptible the soft lead of the .22 LR is to accuracy-degrading damage and minor nicks during the chambering process. [That kind of bullet damage] is eliminated in the V-22 geometry.

Chrono Test — LabRadar vs. MagnetoSpeed vs. Oehler 35P

labradar chronograph test magnetospeed V3 oehler 35P 6mmBR Ackley BRA

We see comparison tests of cars, cameras, and other hardware. But how about chronographs? What could we learn by setting up three different chronographs, and running a 20-shot string over all three at the same time. One of our Forum members, Randy S. (aka AAA) did that very test with three of the best chronographs you can buy: LabRadar, MagnetoSpeed, and an Oehler model 35P. The MagnetoSpeed was attached to the barrel of an F-Class rig, with the LabRadar placed on the left side of the shooting bench. The Oehler 35P was positioned about 23 feet downrange. The photo above shows the set-up. A 20-shot string was recorded with the results in a spreadsheet.

AAA talks about this interesting experiment in a Shooters’ Forum Thread. Here is his report:

Comparison Testing Three Chronographs

We all have our favorite chronograph. Each gives a number, but how would that number compare to the same round fired with another chronograph? I wanted to know so a friend and I set up the following test with three chronographs: LabRadar, MagnetoSpeed V3, and Oehler Model 35P.

For the test we fired Berger 105gr VLDs over the three chronographs simultaneously. The test rifle was my 6mm BR Ackley (BRA) F-class rig with fire-formed brass and 200 rounds on the new barrel.

Chronogaphs Tested
LabRadar
MagnetoSpeed V3
Oehler Model 35P
Temperature: 86 deg. F
Elevation: 854 feet
Cartridge: 6mm BRA (105gr Berger VLD)
Time between shots: 45 seconds

To start off, five rounds were fired to make sure all systems were recording and to warm the barrel. Then the test was 20 shots fired across all three instruments with 45 seconds between shots. The Oehler was set 7.5 yards from the muzzle so 12 FPS was added to the recorded value.

We were using the internal trigger on the LabRadar. The manual says the Vo indicated is the actual muzzle velocity when using the internal trigger, but not if using the Doppler. The 12 FPS Oehler adjustment (back to MV) was based on the Berger Ballistics Calculator.

The LabRadar Chronograph is on sale now through 12/7/2019. Buy for $499.95, a $60.00 savings.

Results of the Triple Chronograph Shoot-Out:

LR-M is FPS variance between LabRadar and MagnetoSpeed V3. LR-O is FPS variance between LabRadar and distance-adjusted Oehler 35P. You can see all three chronos were very consistent. ES was identical with the MagnetoSpeed and Oehler 35P, while SD was identical with the LabRadar and Oehler 35P. CLICK HERE for spreadsheet.

The tester, Randy S. (aka AAA) says: “Judge for yourself, but I was impressed by all.”

Comments by Forum Members
Our Forum members expressed interest in this Triple Chronograph test. Some confirmed that the LabRadar and Magnetospeed give very similar FPS numbers, based on their own tests:

“Great test and thanks for sharing. I’ve tested my MagnetoSpeed and LabRadar together and results are always within 2-4 FPS of one another.” — Big D

“Very happy to see your numbers support my decision to buy a MagnetoSpeed. Had read reports comparing it to the Oehler and the numbers I get seem to be supported by my long range shooting results. Many thanks for taking the time and effort [to perform] this comparative test. Always good to get actual test results.” — Texas10

“I did a 4-shot test with my MagnetoSpeed and another shooter’s LabRadar a couple of days ago. The results were within 4 fps with the LabRadar being optimistic.” — Pat Miles

Forum Member Powderbreak studied AAA’s original spreadsheet from the chronograph trio test, then figured out the shot-by-shot FPS variance between the machines. He concluded that all the machines performed very well. Powderbreak posted:

Analyzing the Triple Chronograph Test — What Can We Conclude?

AAA did a great job of comparing the 3 chronos. What conclusions can be drawn?

1) I have not checked the manufacturer’s claims of accuracy, but the three chronos are very close to one another. There is no way for us to determine the actual true velocities, but we do not need to do so. Any of the chronos would be more than adequate for an accurate shooter.

2) The resolution of the three chronographs is actually pretty astounding. One foot per second (FPS) is a resolution of 0.033%.

3) AAA did a great job of reloading a very consistent round. With an extreme spread of 33 fps out of 3014 for 20 rounds, that is only 1.09% total spread of velocities.

4) There is a closer velocity match between the MagnetoSpeed and the LabRadar, but that does not mean the Oehler is less accurate. There is simply an offset between the Oehler and the other two. This could be due to the greater distance, the location, or the internal working of the Oehler.

5) Believe your chronograph, it is probably the most accurate reloading tool that you own.

Brian Litz of Applied Ballistics carefully explained the operation, set-up, accuracy and comparison of AB’s chronographs in his books. [Those books] are well worth the money, and give great insight into the workings of chronographs.” — Powderbreak

Reloder 23 and Reloder 26 — Good for Magnum Cartridges

Alliant Bofors Nitrochemie Reloader Reloading RL Reloder powder 22 23 25 26

Do you shoot a magnum cartridge? Here are two modern-formulation powders you may want to try: Reloder 23 and 26. We have been particularly impressed with Reloder 23. It has worked well in competition for target cartridges such as the 7mm RSAUM. Reloder 23 is like a slower version of Reloder 16 — a very temp-stable powder which has proven a worthy rival to H4350.

Ever heard of Alliant Reloder 23? Or Reloder 26? These two relatively new European-produced Reloder propellants were introduced in 2014. Most folks haven’t tried these Reloder powders because it took quite a while for the first shipments of RL 23 and RL 26 to arrive in the USA. But now these two new propellants are available in the USA, with substantial inventories in stock at some larger vendors. For example, Powder Valley has both RL 23 and RL 26 in stock now at $23.50 per pound. Many other vendors have ample RL 23, but RL 26 is a bit harder to find.

From our Forum members who shoot large magnum cartridge types with heavy bullets, we have heard good things about both RL 23 and RL 26. Reports from the field indicate that both these powders are delivering impressive velocities with low velocity ES/SD.

What are the characteristics of RL 23 and RL 26? That question was answered by Paul Furrier who works for ATK, the parent company of Alliant Powders. Posting in our Shooters’ Forum, Paul writes:

“Let me provide some factual info about these products. Some of the stuff that gets propagated is not correct. Reloder 23 is produced by our Swedish partner Bofors, and Reloder 26 is produced in Switzerland by our extremely capable partner Nitrochemie. I have seen it stated that they are both made by Bofors, so that is incorrect.

I have also noticed people are equating Reloder 23 to Reloder 22, and Reloder 26 to Reloder 25. Both of those statements are definitely incorrect. We do state that the performance of Reloder 23 is similar to Reloder 22, and it is, in general burn speed terms, but they are most certainly not the same. We have worked quite a lot of recipes for Reloder 23, and they are not the same as Reloder 22. Reloder 26 is definitely slower burning than Reloder 25, so there shouldn’t be any confusion there either.”

Furrier says that RL 23 is NOT sensitive to temperature shifts: “Reloder 23 was developed to bring a truly temp-stable powder to the Reloder 22 burn-speed range using Bofors new process technology. This is the second product developed for us with this TZ® process, the first being AR-Comp™. We see terrific efficiencies, SDs, accuracy and flat temp response from these powders. Please try them, I think you will be impressed.”
