I did some work on an Aluminum bullet for a 30-06. We used a custom made cutter to reproduce a 168 HPBT that weighed only 48 grains. We were trying to make a high speed bullet for police snipers. Trying to reduce the ability to pass thru a lot of walls. Topped 4000fps and was accurate at 100 yds but went into the dirt soon after. We used 2011 round stock which is a copper alloy based. No leading was ever observed. Since your machining yours also you might look into something like this for a speedster round. Im gonna follow this. Great idea.
Good luck with the project! I tried something similar 40+ years ago. Biggest problem was blowing the rim when max pressures were exceeded.
Be forewarned, if the rifle has a detachable mag be careful about what's under it. Shrapnel sucks!!

Awesome
That’s the plan. Run up till it ruptures and work the load backwards.
I believe you said you may start with Red Dot powder. Tightwad actually burns faster, and the flakes are smaller, which might be a good fit for the 22 cases? I’ve used a lot of it in 12 gauge Winchester hulls, they don’t leave you much room to work with, and I gain quite a bit with Tightwad. Burns very clean in 12 gauge, 22 IDK.
Smaller flakes would probably Be a good thing. Thanks.
Having the barrel setup for my quad now since I had problems. Still going to do more work with titewad but Winchester aa lite is also on my list

Tagged to see the outcome.
Hi Geno, any other updates? Very interested to see where this project goes...
Also interested, keeping tabs on this.
Get it worked out and vudoo will likely have some rifles returning for modifications.

Only update I have is, I’m getting the barrel that I had on the Vudoo, setback and fitted to my Sako Quad. Had a little setback and went down one path to hopefully fix it and that didn’t work so I’m changing gears. Ordering a couple wmr mags so I’ll be mag feeding these as well.
Many, many years ago, like back in the early 1960's, I read a magazine article about an experimental bolt action 22LR rifle that used a second chamber. Bar stock was dovetailed into the bottom of the barrel several inches ahead of the action and that bar stock was bored and chambered for a .22LR case. Then a plug was threaded in that acted as a bolt. The chamber was vented into the bore. I think they called it something like The Supercharger.
It has some foundation in work done in the 19th Century by James Richard Haskell.
A fired 22LR case was filled near the top with Powder (Unique?), and sealed with a drop of cellulose acetate cement (model airplane glue).
As the first round fired, the charge ignited the second casing, and the entire charge equaled two cases of powder. Numbers are difficult to remember from well over half a century ago, but it was a spectacular success.
Might have some application in this project.
During WWII the Germans built a Super Weapon, the V3, a cannon barrel that was aimed across the English Channel. It had right angled extensions off the main tube that almost looked like ladder pegs. Each of them was loaded with powder bags and served as sequential charges to continue boosting the projectile's velocity. I believe it was interrupted by the RAF, but knowing the Germans, I wouldn't be surprised if it would have worked.
Saddam attempted to duplicate it, possibly aimed at Israel.
And finally, look up the works of Dr. Gerald Bull. His participation in that Project Babylon was what got him assassinated by Mossad.

To some extent it did, I believe it's called the 6.5 Creedmoor now.
Barrel is setup for the Sako now 
I just ran across this thread. Very interesting. I am curious to see how it works out.
But otherwise, I think it's very cool! I am interested in how it works out.
I know there is a wide range of type of 22LR competition (and governing bodies). Most are not "rimfire", but actually specify "22LR" (I think) with I assume the definition being used is the SAAMI definition of 22LR. I believe the SAAMI spec includes an OAL of around 1" +/-. The OAL of this solution looks to be much longer, so might the argument be that this is not 22LR? Also, I can imagine that some 22LR competition hinges upon the idea of "cheap and readily available" ammo. Plus to remove the need to handload. I can imagine that if something like this becomes viable, that some (maybe not all) organizations would adjust rules to prevent it.
But otherwise, I think it's very cool! I am interested in how it works out.
I could see how someone might want to go by saami oal but that would be a stretch in my mind. Guys that load for ftr are no where near the saami oal. A 22lr case is still used so it SHOULD fit into the definition of 22lr. If it someone complains and decides to make the rules more specific as to exclude this. Then so be it. Just because some people want to stick with what is generally considered normal doesn’t mean that should be the way it stays. I don’t have anything to do with any governing bodies in any of the shooting sports. I just shoot. I’m pushing the 22 past what most people consider possible for the sake of advancing the sport.
It’s looking like titewad might be too fast actually. Making a bigger jump than I normally would to a slower powder to cover more ground in testing. 
Shoot some groups already!! Let’s see what it can do
Still simply finding the right powder and pressure ceiling.
@Mike Casselton that’s why I moved to lil gun after I found Titewad was too fast. I made a bigger jump than normal to cover more ground with less ammo. I’m actually thinking this might be pretty close to where I want to be. Been testing pressure only so far. Im putting a scope back on now and I’ll sight it in and test accuracy and pressure like normal from here on out
Took 3 charges out to get some speed numbers and a more solid zero. The results are promising. It proved my mullets are working like they should. I’ll keep working at it as time and weather permits
@Geno C.
I think you're in the ballpark for powder.
I just looked at some data for the 22 CCM (CF version of the 22 mag, based on a heavily modified Hornet Case) and the fella used AA-9, AA-1680 and H-110.
The case capacity is larger, but you're also using a solid IIRC.
It's too bad the home piezo transducer system isn't still on the market. I think it was Oehler that sold them. That could shorten the curve to success.

H110 isn’t too far from where I’m at actually. I’m just about out of case capacity so I might have to take a step or 2 faster on the burn rate chart
I’m hoping it can get over the transonic range but I’m having my doubts
They really are quite different when you put them side by side
So the same load that was showing good sd earlier in the week is stable. It did even better today. 
Got up to 1162 today lil gun. Ran out of case capacity. Got some fun recoveries off the 100 yard plat
Maybe you stated before, but where are you getting the primed cases? Are you pulling bullets to get them?
I thought it would much more difficult to find the primed brass.
Do they sell direct to public? Their website makes it sound like they're geared to distributors.

Currently these aren’t available to the public. The guys and badlands and myself wouldn’t want an unproven design out there. It’s one step at a time in the testing and evaluation. Once I’m certain that it doesn’t what I want it to do, then it’ll be available
You can see angle of impact!!!
Yeah, the plate was angled down though. I did that to try and recover some of them. It’s not coming in nearly as steep at 100 as these would suggest
Got a max speed of 1289 this morning. Think that’s about all it’s going to get with this combo.
