Vudoo Gun Works V-22 Rimfire Bolt Action

Cheers. Have you noticed ES lowers around that point? I chronied 25rd of SK Rifle Match and had an ES of 64. I was thinking its a tad high for that ammo. Every other rifle I've chronied it is around 40 or under.
Another feature that raises Vudoo far above the rest. After dealing with the bolt pulling out of my CZ-455 in a match, this feature really says a lot to me! (Bolt pulls out of the CZ because it has a trigger kit in it; anyone who understands how a stock 455 trigger works knows why there is a direct correlation between pull weight and bolt coming out of the rifle.)
While my first-gen Vudoo does everything I want it to do, I might have to acquire a 360 just because it's a jewel to appreciate.
Went out to the range today to confirm dope and take time on paper. Also took time to do all the proper natural point of aim, follow through etc to try to get a decent set of 50yd groups. The freshly cleaned and lubed 360 felt great. Really smooth feeding and shot well. The one larger group, I rushed since they were going to call cease fire for target change and I wanted to fit the group in.
I checked my kestrel and dope out to 200 and it is within .05mils which is good. Slight left to right wind. Kestel called for 7.34mils and I dialed 7.3mil.
My 24xx lot shoots well enough for me to use until it's done. Chronoing at 1055. 2mils to 103yds, 7.3 mils to 200 yds. 50yd zero.

There are some very nice groups on the 50 yard target above.
On the one that measures 0.219" on the bottom left corner, how can a group be smaller than .22" when there's clearly paper showing between the two widest apart bullet holes?

Anyone using MKM magazine extensions for plastic mags? If so, any complaints or success stories?
I haven’t had this problem, but in September the bolt stop on my Vudoo 360 sheared off. Vudoo was quick to send out a replacement. I was shooting tonight, and it sheared off again! It’s been 319 rounds since replacement. I’m not working the bolt excessively hard. Has anyone else had this problem?

Good catch! I remeasured it and it's .449. It looks like I quickly measured top/bottom instead of that diagonal which is larger. The group should've been .228, and not .219.
Ive got the MKM mag extensions and they work....only problem is they have fallen apart on me during a stage. I've had to wrap tape around them to keep them together. Might be me being too rough on them.
I have a .9" at muzzle, non threaded barrel. What is the best recommendation for a tuner? I know it's not necessary for PRS style targets, but it also doesn't hurt when people do cold bore challenges shooting golfballs at 200y. Is there a clamp on tuner that is robust enough to handle PRS and works well?
Harrel's? Is there a set screw that really locks in the setting? I think I just call them and have them bore it out .9" I also don't want to increase the length anymore on my rifle (already 22"). So can I jist slide the Harrel's all the way back on my barrel so it's flush to the crown?
I heard also heard this SFP Pro Tuner.
Thanks!

No set screw on the Harrell. A wrap of electrical tape does the job. Harrell cannot be set back to be flush with the crown.
In order for a tuner to work, it must extend past the muzzle. There are mid barrel tuners but they are always used in conjunction with conventional muzzle tuners. If your barrel is .9 x 22 it probably won't respond well to a tuner if at all.
Finally solved my magazine issues with my Gen 2. I have been using the plastic mags in a MPA Hybrid Chassis. I have had issues with the plastic magazines if bumped even just a little, which can be problematic on the clock when the rifle is resting on a bag. Push the bag there is normally a jam. My chassis has an adjustable mag latch and I could never find the sweet spot that would use both metal and plastic mags. I added a second and third metal magazine to the mix and decided to set it up for the metal mags only. MPA makes small plastic inserts for their chassis to fine tune the fit. It slides in the chassis above the mag latch. I got the metal magazines to fit perfectly, (at the perfect plastic mag setting the metal ones would not click in) with the bolt just missing the top of the mag. I took this configuration to the range yesterday and I literally could not make it misfeed. I shot several mags on bipod and rear bag, no problems. I then shot several pulling very hard to the rear on the mag, bipod, shoulder and left hand pulling hard on the mag, still perfect. Then I shot several holding the rifle up by the mag, hand cupped underneath supporting the weight of the rifle, again no issues. Then I put the rifle on a bag on a rooftop prop and pushed hard against the bag, still perfect. If you have a MPA Chassis and are having trouble I suggest you order the little plastic blocks from MPA and see if they work for you with the proper mag latch adjustment. I used blue loctite to help keep the plastic piece in place.
I had to use Gorilla Glue. Even basic "Super Glue" wasn't enough to keep the plastic block in place on mine longer than a single range session with multiple magazine changes.
Prone 22” MTU V22 360 10-shot groups with Center X and SK STD+. For consistency, initial 10 shot groups are on the top left corner and followed by the test groups on the respective bottom right corners.
I’ll happily continue buying SK STD+ for this.

Put a few mags of random SK and Lapua ammo through my 360 today after a NRL22 match with my v22, my 360 seems to like SKLR, happy about that.
This pic was 10 quick shots at 50. Probably rounds 30-40 down the pipe.
No hiccups fast feeding with plastic or aluminum mags in my XLR with adjustable magwell.
Not as smooth as my uncoated Gen1 v22, melonited only, but the short throw felt better at speed than I was expecting, and I'm sure the ceracote will wear in.

That was the range session. Ran 10 rounds thru and had to leaveGreat start! Truth now… how was the rest of your range session?
Have only put about 200 rounds through it so far, awesome rifle. 360 to semi replicate the AXSR.
Sent my Vudoo to the lapua test center in Arizona. Took right at two weeks to get results. Results came on Friday, with top two lots picked (he only had one case of the best lot - and I had suggested I would buy two). Responded that I would take two, and to use good shooting inc for the seller. By Wednesday of the following week (5 days after testing) I had two cases delivered to my house. The action made it back in Friday (7 days after testing completed). Devan (the guy at the test center) answered a lot of questions along the way, and was very helpful.
I cleaned the action, remounted my scope, and shot the rifle in a local NRL22 match yesterday. Took about 15 rounds to really tighten things up, and another 15 to confirm dope. I still struggle some times with the bolt being very hard to close using the metal 15 round magazine. I need to tinker with the mag catch today, and to install the mag blocks (MPA hybrid chassis).
Here are the 50 meter and 100 meter results from my testing. The rifle has a 22” MTU barrel, and it has over 2,000 rounds when I sent it for testing.
Just thought that someone else might benefit from seeing what you get.
Cost -
$50 for shipping and insurance (TN to AZ, ground via UPS)
$64 for return shipping/test fee from AZ to TN
$2,190- for two cases (10,000 rounds)
50meter and 100meter

Are you happy with the results? Are they substantially better than you saw on your own with your favorite match ammo?
Probably not substantially better, but that is a subjective assessment. I could have sent the current center X to the test center, and asked for a baseline using that. But I didn’t think to.
There are a few interesting things with the results that were sent to me. One was that the worst lot of Center X was remarkably worse compared to the “best.” The image below is 100 meter groups. I’m sure most guys will be “yeah, duh! Anyone knows that!” But this was done in a very controlled environment, removing as many factors as possible.
I don’t have enough of the “old” lots to do a real world comparison. I was able to shoot 3/4” groups (5 shots, max center to center measurement) at 100 yards. But I never tried to shoot a group with 10 shots. So I do believe the new lots are more consistently accurate. I have not found a good conversion to change a 26mm group at 100m to MOA at 100 yards. Anyone - please share the math there to get a good compassion. And that 26mm is outer diameter - not center to center.
And quite honestly, I used this service to buy enough ammo to shoot competitions for well over a year. That alone was worth it for me.

+1 from lot to lot it's pretty crazy the difference... for my testing for my 18" Gen 1.2 Kukri, my best lot at 50m
At 100m was
This was pre pandemic and I was able to order 4 cases back then. Luckily it shoots well out of my new 360, but I am curious how well my new 360 will do at the test center. I have about 550 rounds through the 360, so another month or so of matches and I should be good to send it in. My new 360 is a 22" Benchmark.
I might have them do some testing of Midas+ just to have something for national matches if I need to eek out a little more consistency.
Take the 100 meter result and multiply by 0.9144 to get the equivalent result at 100 yards.
So other than doing the x0.9144 meters-to-yards conversion, subtract 5.56mm from the edge-edge-to-edge measurement to get center-to-center (1/2 of bullet diameter from each side, so one full bullet diameter). Then convert the mm at 100 yards to inches (divide by 25.4) and finally to MOA (x1.047 if at 100 yards, or 2x1.047 if at 50 yards).
Example: convert 26mm edge-to-edge at 100 meters to equivalent MOA at 100 yards:
Step 1: 26mm - 5.56mm = 20.44mm (converting edge-to-edge to c-t-c)
Step 2: 20.44 / 25.4 = 0.805 inches (convert mm to inches)
Step 3: 0.805 x 0.9144 = .7361 (0.805 inches at 100 meters would be the equivalent 0.7361 inches at 100 yards)
Step 4: .7361 x 1.047 = 0.771 equivalent MOA at 100 yards
I think I've got that right!! It would be easy enough to put the calculations into an Excel spreadsheet... here is my take on it -- inside the ZIP file is an Excel .xls:

Thanks - so for the two 10 shot groups above, the average was 29.8mm edge to edge at 100m.
Converting to inches at 100 yards -
29.8mm/25.4mm/in = 1.17 in (edge to edge)
to get CTC, subtract 0.223 in
1.17 in - 0.223 in = 0.950 in (10 shot group, CTC, @100 meters)
converting inches at 100m to inches at 100 yards - multiply by 0.9144
0.950 * 0.9144 = 0.87 in @100yards for 10 rounds, CTC
Am I blown away by the results - not really. Was hoping to see something closer to 1/2”, but I really have no comparison.
I won the match yesterday, bearing a couple of really good shooters. Was it the new ammo? Maybe. Was it the 20 pound full setup with chassis, weight kit, and good optic. Maybe. Was it luck? Most likely. But what I am glad is that I am relatively confident that going forward, the ammo won’t be my excuse when I miss targets.

So for your rifle and their lots, CX did better than Midas+ and X-Act did best overall?
Can someone interpret the results for me so I understand what I'm looking at. I get the gist and you can see by just looking at the groups. But I'd like to know what all the abbreviations mean and how they relate to how we normally talk here on the hide. For example, they measure edge to edge rather than center to center, etc.
An edited picture with arrows and explanations for this caveman please.

Thanks littlepod, here is a link to the manual for the insomniacs in the crowd.
In it I found the answer(sort of) to my one remaining question. The bar graphs on the right of some of the pages are the 'ring value distribution'. I assume that would be the rings of an established and sanctioned target, likely popular in Germany/Europe. Can anybody share some light on that one?
I'd also be interested in opinions on the usefulness/utility of DHH. It seems to me to be pretty irrelevant. I use distance to center of each shot and standard deviation of same. In order to be anywhere near competitive my system has to shoot such that the average distance to center plus two SD's stays inside my 10 ring. This is not a common occurrence for me.

@Taqwin
I do not know. I purchased the barreled action from Altus and they did not specify.
@littlepod
The comments were from the tester. My favorite is ES (Extreme Spread) Accuracy, that is specifying a circle of a given diameter around the AP and keeping all the shots, either using best edge scoring, center of the bullet hole or worst edge scoring within/on the circle. However, the Lapua Test Center only does ES Precision Testing but that is the next best test to ES Accuracy Testing. I purchased a case of the preferred X-Act with goal of consistently shooting 0.3 milrad groups at 200yd with various support systems, bipod and tactical rear bag on bench, small tripod with ball head on bench, large tripod on ground, etc.
As I understand it, Lapua manufactures a lot of 22LR ammunition and then tests it. Those lots with the most consistency are sold as X-Act, next consistency Midas and least consistency Center-X. It would be interesting to know what statistical measures are used but variance in muzzle velocity must be one. The head stamp is the same for Center-X, Midas and X-Act. Since there are no environmental effects at my range for the times I shoot, accuracy comes down to variance in muzzle velocity and marksmanship.

My opinion on DHH is that it tells you how big the average shift is between shots. I could see that being useful in a benchrest match to make subtle hold corrections. When I look at my 100 yard groups, you can assume that the shots “walked” a certain direction as they were fired. I looked at that manual, and the software is capable of printing the order of the shots, but I suspect it would make the graph too busy, and not helpful for most.
Good luck to anyone who decides to head this path. I hope that my experience and the experiences shared by others here can help get the most out of your Vudoo (or any other rifle you choose to test). I have several thousand rounds of ammo from when I thought I would do my own lot testing. I should have just saved my money.

That is what I believe also. Center-X, Midas, and X-Act are all made from the same components on the same machines. Each lot is tested to determine what box it goes in. Given that there are barrel to barrel variations in ammo performance this explains why a marginal X-Act lot could easily be outdone by a top Center-X lot.
This is a good place to add that I think SK does the same thing with their lines. ie.Rifle Match, Standard Plus, Pistol Match .... Long Range Match, Biathlon Sport, Pistol Match Special .... Flatnose Match, Flatnose Basic.
The million dollar question is what do they do when things go really well for them and they get an overstock of the higher end product ... I bet some Midas worthy lots get stuffed in Center-X boxes. Hmmm ... I wonder.
Hey all, my Vudoo Three60 has a liking for RWS R50. Is there a different follower that suits the RWS bullet shape? I have the red follower now and it feeds 90% of the time but I get a few feeding issues. Just seems to be a bit more picky with feed angle in the mag then SK.
I'd have never thought a mag fed rimfire would be capable of shoot groups in the .1s and .2s at 50m with consistency until I got this rig. Its crazy good. MB, you did good work mate. Thanks

Sheared the bolt stop off my Vudoo 360 with just under 2000 rounds. I think I run the bolt firm but by no means hard. Attached is a link to an Instagram video of me running the bolt. Has his happened to anyone else?
