What better place to ask than here. What are the action bolt torque specs on vudoo 3 mounted to a MPA matrix pro chassis? Please remove if this doesn't belong here.
This is THE place to ask, and I've always used 65 in lbs. and follow a specific process to torque the action bolts.

For the life of me I could not get my Stinger mag to not shave on my Vudoo. I’m not stranger to adjusting mags but even then couldn’t find a sweet spot that it liked where it would feed without shaving. I know it’s not a VGW product. Kind of why I quoted feeds all day long. Yeah mine would feed all day but 100% shaved each and every time.
I had the exact same issues...
 
As Mike alluded to your issue is not with the magazine per say (depending on where you want to assign blame). The shaving is caused by the round not fully seating up into the bolt face. This condition is the result of the magazine spring not having enough force to overcome the tensioner and extractor. Is the tensioner and extractor springs too strong or is the magazine spring too weak? Pick your poison, but have you to fix one or the other. We have magazine spring tuning kits coming out for the Stinger mags very soon as we can control that on our end.
Love to try them when ready!

We can send you a heavier spring. I have been wondering why some Vudoos feed from them great and some have that issue. My theory is that maybe some actions were built with the single shot extractor/tensioner springs as they would be heavier to extract from tighter BR chambers without the worry about feeding from a magazine. @RAVAGE88 may be able to speak more to that possibly though.

Yessir, I believe we're on the same page, but the feed timing issue will still be there. The small metal magazines are set up for a small diameter receiver and there are a few other dimensions that dictate timing for the small diameter receiver, but the bullets are still damaged en route to the chamber.

Move that to a larger diameter receiver and it gets worse, regardless of the receiver mounted block/hanger arrangement.

Both CZ and Tikka T1x do the hanger style, and for the most part have less magazine related feeding issues.

I guess it comes down to if you want AICS style mags or not.
I like T1x magazines and was one of the reasons I did a T1x build (which in hindsight I should've done a CZ build).

I don't see the appeal over masively oversized magazine for "training" purposes when guys are running 10-15 round centrefire magazines.

I don’t think I said there were feed issues and I’m noting small diameter receivers and didn’t specifically mention CZ or Tikka. I noted damage to bullets, again in small diameter receivers. Not saying it happens in all of them.

To be clear, I will never use anything but an AICS style magazine in a centerfire-sized-Rimfire receiver.

MB
From looking at these AICS rimfire magazines they all seem to have the smaller section that puts the round up to be picked up by the bolt ?

Either a hanger attached to the action like the CZ or the bottom of the receiver more suited to accurately locate this smaller section of magazine would make the oversize for rimfire ACIS footprint easier to setup ?

Question for the engineering types, does the sensitivty to spring tension have any bearing on the slanted stack vs the 'straight stack' debate?

How you stack the cartridges effects the amount of the spring force absorbed by the friction in the stack-up, giving you a different net amount of force the cartridge will be feed into the bolt with. How much that effect is I have not quantified however anecdotally it seems my straight column magazines need less spring pressure than my slanted ones do.

Got It...That's helpful to understand. Thanks for the reply.

I have a Vision Pro chassis I'll be throwing my barreled action into (when Mr. Lott is finished with it!) --> is 65 in lbs what you would go with for this chassis as well?

Also -- what do you mean when you say "follow a specific process to torque the action bolts"?

I'm new to ALL of this and want to make sure I'm gett'n it right from the get-go. I HATE having to go back to re-do something because I was like a kid in a candy-store and plowed through some critical steps in whatever I'm doing :LOL: !

I’m glad something was figured out even if in theory that it could be an issue with the rifle itself and not pointing the finger at the end user. “You sure you are setting up the mag right?”

Follow the Vision Pro specs. 65 in/lbs on action.


Now some will do stuff like 15 front and 15 back and then 30 front and 30 back and then 45 front and 45 back and then 65 front and 65 back. It doesn’t hurt anything and if you want to do that then go for it but I usually put in my 65in/lbs torque limiter and snug front and snug back and then a little more front and a little more back and then to the clicks on limiter on front and then back. Doesn’t need to be super specific to the values used to get to 65.

Forgot to add I do it with the stock butt on ground and muzzle up so recoil lug is set against stock/chassis lug recess.

I torque my actions in while holding it upright (pointing at the ceiling). This biases the recoil lug up against the abutment in the chassis while tightening down the action screws. You don't want the action floating as it can shift later causing a POI change.

Also, torque the receiver down, front bolt first, rear bolt second, but WITH THE MAGAZINE INSERTED. This will properly align the receiver along the longitudinal axis,

While we’re all on the topic of torque values….Manners TCS Max micro chassis specs? Don’t want to assume 65, but cannot find literature that suggests otherwise.
I have sent Manners an RFI regarding..

Build is in process, have not torqued the 360 into place yet.

That’s the mini chassis. 65 front and 45 rear.

Typically, the rear bolt of the Manners chassis is 45 in lbs.

It is the Micro chassis with MDT bottom metal.

I am pretty sure you made a video addressing this way back when. I feel like early on there was issues with feeding that blamed the magazine, then it died out after that video. But I have found this is a critical step for the 100% reliability I have experienced with the 6-7 different barreled actions, 15-20 magazines, and somewhere over 10 different chassis / stock & bottom metal combos I have had across all 3 generation actions. I am also particular about how I load my magazines.

I prefer the vertical stack vs angled because the vertical has a single force vector vs two force vectors for the angled. Two force vectors require more spring, but there are some advantages to feeding protruding rim cartridges at an angle because the magazine is easier to load correctly.

The vertical stack isn't difficult, but generally, it's more common to load it in a way that induces rim lock, but most have loaded without having experienced rim lock, me included.

Dude, that seems like forever ago.

Standard on the TCS Max unless noted otherwise.
This one happens to be the rimfire edition, but the only difference is the dual sided clutch and m-lok slots.

Wouldn’t have been my choice but if no one here knows just give Manners a call. They have great CS and can get you answered fast.

Just an idea, I know it’s safe to dry fire train with a vudoo, but would it possible to make a dry fire bolt? Just one stripped with the lugs and handle and what not for safe dry fire practice? @RAVAGE88
Not a bad idea at all, but not necessary. The tip of the firing pin in a fully functional bolt assembly stops .010" shy of hitting the barrel breech, which is what makes it dry fire safe.

Ok, thanks to the responses from my weekend mass email, I have a solid handle on per generation inventory levels. Not surprisingly, the greater number of actions out there is the Gen 3, Three60 Repeater. So that's where I'm building inventory first.
I'm now going part by part in the SolidWorks Assembly Models to validate all eight configurations of the Gen 3 (four for the repeater, four for single shot). As I validate a part, it gets placed into manufacturing engineering and validation and then production. This might sound like a lengthy process, but not really.

The thought struck me as I've been reviewing files, I could start making these things today if I took a notion to do so.

360 is only way to fly if ya do a lefty, myself and a few other lefties run 360 VGW and CZ 457. My preference is 60* now after running the CZ's .I have a V22 and B14r in the safe.As others have stated the 700 foot print is a plus for lefties stock and trigger choices.
For the CZ herd,I bought a chinese milling machine after MDT says no can do LH 457 chassis.15 mins on mill.done
LH 90* bolts,like B14r, will hit or not allow full stroke of bolt handle on some scopes ,like the batt housing on a S&B PMII,newer combo night/therm optics,some throw levers,various farkles we hang off of 34mm scopes were made with RH in mind.
Just an old lefty's 2 cents
