Vudoo V-22S Single Shot BR/F-Class Action

Got my Vudoo V22S back together just in time for our ARA Unlimited match yesterday. Also shot my personal best high card of 2350 13 X's during the match. I'm thinking it's gonna do just fine!!! :D

Maybe a dumb question but do those “bloop tubes” make a difference?
The short answer...... Yes, they do work for me.

I've been using this Bob's bloop tube for about a year now and not even thinking of shooting without it. I've had the opportunity to put them on 6 rifles and only one did not show improvement with it. I will say the total rifle package has to be working well to see a difference. The tuner itself makes the most difference and the tube is like icing on the cake, kinda brings it all together.

It's my understanding the tube helps stabilize the muzzle blast and bullet as it leaves the rifle. Others say it's only adding weight and that can be done without a tube. I can tell you the tube I use has a pinch point inside like an hourglass, other shooters with way more brains than me said this creates a negative pressure inside the tube. If I recall right they referenced to something concerning jet injection.
Others state the tube was originally design back in the day to increase sight radius for iron sight rifles, which makes total sense to me also.

Not a dumb question at all Sir and the same one I asked when jumping into the rabbit hole. I never got a real answer so I bought one and tried it for myself. I will say I'm glad I ran into Mr. Bob when I first started looking into tubes.

Hope this helps. :)

I was looking at the one on Harrell's site to go with the tuner, but I wasn't really sure if they actually did much. Did you have to readjust your tuner once you installed it?
I didn't have to change my tuner setting. I have tried a couple different tuner setting over the last year and always come back to my original tuner setting.
As I stated, it made just a little difference and the complete rifle setup has to be working well to see it. It was a surprise to me when I noticed the change as soon as I put it on.

Here are the results from our ARA match day before yesterday. I shot 4 different ammos to get these results, a different ammo for each card. I do not change my tuner setting at all. I've tried in practice and always come back to my original setting.

Have you been able to do a lot of shooting at each turn or just starting to try them out?

Has the grey spring been the one that worked best?

Have you tied the other springs?

Thanks
Have tried other springs, currently using 16# white @ O turns, getting .017 depth amg 0 FTF. Want to try lighter springs to reduce vibration and still get <.015 depth with 0 FTF’s, Eley ammo. What spring do you use and what depth hit do you get, with Eley?

I've been using the blue spring with 2 turns out for about a year now with good results. I don't have a way of measuring strike depth so not sure what it is.

As far as failure to fire, I was getting about one in 100 with Eley and RWS, none with Lapua until temps dropped to about 30 degrees. Through trial and error I figured out my FTF's were caused from the way I was lubricating my bolt......too thick and too much.

I've since changed the way I lubricate and all FTF's, with any ammo at any temp, have gone away.

My 16# spring is at 1 turn NO FTF’s, sorry for the mistake of 0 turns.
Match Sunday 8-18-24 IBS Hunter benchrest at 100 yds. I shot 2 card 475 with 8 x’s for 2nd place, winner shot 477 with 3 x’s for 1st. Match was a blast. I had 3 8’s & 1 7 that I let get get away. Range temp was <80 @ end @ 10 o’clock, wind was RT to left @ 1-4mph a perfect day. This was my first match after a 1 yr off.

I bought a spring kit a couple weeks ago and tried the blue - 13lb spring today. The bolt lift was considerably lighter than it was with the stock spring, I have no idea what the stock spring weighed but at my match today I noticed that while I was getting some very tight shots I was also getting the wildest flyers I have ever had with the rifle. I am not sure if turning the pin out will make a difference, but I will have to try it. I am not really sure how far the pin can be adjusted, I know if you screw it too far in you will have light strikes without enough pin fall and the bolt gets harder to open after firing (at least on my rifle) but how far can you adjust the pin the other way, just until the shoulder hits the bolt nose or can it be adjusted farther that that? I am guessing if the shoulder is hitting the bolt nose than that is as far as you can adjust it. I would also think that it would cause some excessive vibration too?
 
I have been unable to get get my V22s, Ace barrel, to shoot as accurately as my V22 Three 60, Bartlett barrel. I had a few questions that I posed to Vudoo and I received this response from Vudoo.
Hi Bill,
Good question, but we go about our measurements a little differently. We’re concerned about the measured strike depth we get on the rim of the case. For Lapua, we’re looking for about .018-.020 between unfired and fired. Strike depth can be affected by the spring weight, firing pin shape, ammo type, firing pin lubrication, headspace and firing pin adjustment.

Please note that if a firing pin is adjusted to make contact with the stop upon dryfiring on an empty chamber, it will not make contact with the stop when firing a live round. The force from the live round will be taken up by the tip of the firing pin hitting rim of the case.

We want the firing pin to make contact with the stop on dryfire, so the force is not being exerted into the cocking piece from the cocking slot in the bolt.

Please let us know if you have any questions.

Best,

sorry Bartlein
 
So judging by my bolt , there should be no space between my firing pin shoulder and bolt nose, IF I am dry firing? I don’t do any dry firing with my V22s but it’s good to know that with live ammo the shoulder hitting the bold nose will not be an issue. That is if I am reading this correctly.
 
My take from what they sent me,.it should have no space, you control the strike depth by spring weight . I have been changing the pin strike depth by first turning the pin out until it is flush with the shoulder, then adjusting the pin strike depth by changing spring weight. I now have the grey spring in and my strike depth is .016-0.17. I measure with a depth gauge off of the back of the bolt as well as with a feeler gauge the distance between the pin and the shoulder. I put a fired case in the chamber close the bolt while pressing the trigger, this places the firing pin just against the casing rim. Set the trigger by lifting and closing the bolt, not ejecting the casing. Fire the trigger and measure the distance between the pin and the shoulder. The difference is the the strike depth. Even doing all of this it still is not as accurate as my V22 Three 60 which has a 22# spring, strike depth of .019, as it came from Vudoo.
My next step will be a trip to Lapua Ohio to test some different ammo in it. If it does not improve, will probably have a new barrel installed. For what it's worth. I clean both V22's bolt after every range trip since it so easy to take the bolt apart. Clean it with Hornady one shot, blow dry and assemble. Hornady s a very good cleaner and excellent dry lube.
