You are thinking a fast powder rather than a slower one. I thought due to longer barrel 16-inch a slightly slower like re-7 might work . Still trying to decide amount of powder?? Other choices in powder Universal Clays or Bluedot. Any opinion on starter loads to control pressure?
Case capacity will be the most limiting factor IMHO.
I tried them but could not get the action to cycle. I used 55 grain 22 cal. bullets also and they seemed to hit the target straight on. I guess it just wasn't really what I wanted to mess with so I never really went any further. I was using AA #9 but I don't remember what the charge was. I think the reason I gave up so easy is I have an AR carbine in 22 Reed Express that is made from 7.62X25 brass. I shoot the commercial 7.62X25 ammo and reused half the brass for the 22. I thought the 22 Sabots in the Tok brass was a cool idea but I could not really get going on that project. I'd love to see somebody else actually get the Sabots working -- that could be a whole new world for the people with Tok carbines. One thing I never tried was the Sabots in my old blowback Tok carbine -- I wonder if that would have worked?
Oh gosh, a mixed powder load? Is there anything you can think of that might work about the same? I just got the blowback upper back together although I want to change out the front sight so I can use a scope -- lousy old eyes with fog rolling through them. I think I still have the sabots and the seater kit. Fastest powder I've got is AA #9 which is no where near the burn rate of unique or bullseye. I guess, before I try to figure out what powder to use, I need to see if I can still make the sabot rounds and get them to feed first.

OK, I don't have any 55 grain, 22 caliber bullets but I did have the ones shown delow. On the left is one that's too long and 68 grains. the next in from the left is a 50 grain Molly and the one on the right is a standard hornady 40 grain V-max.
Below is a picture of my old blowback pre-ban Tok carbine with PPS-43 mag. I ran all three types of bullets show above through the mag and they chambered smooth as silk.
Below is a picture of the Tok magwell adapter for my blowback carbine. The magazine in the picture is again, a PPS-43 for use in a blowback carbine.
I found the old EABCO sabot kit and slapped some dummy rounds together to see if I could get them to feed or not. The real challenge now is to find the right powder and make the action work 100%.

I loaded up 3 rounds with 10.0 grains of AA#9, inserted a sabot using the 50 grain Moly V-max and test fired them. Holy mackerel, the rounds worked and would even lock the bolt back! Now for the problem -- 10.0 grains of #9 takes up too much room in the cartridge case and I could only seat the sabot so the COL was 1.44" -- way too long to fit in a PPS mag. Also, I used the standard carbine buffer, not the heavy 9mm buffer. That's fine with me -- I can use the same lower without changing anything and shoot the sabots or switch and shoot something else. Now to go on a hunt for a good powder.
Thanks! That's what I was hoping for. I did make up 3 rounds with 10 grains of AA#9 and the 50 grain moly V-max and they worked really good. One problem was the powder took up so much room in the cartridge case that I could only seat the bullet in for a COL of 1.44" so they would not fit in the PPS-43 mag -- I had to single load each cartridge. I checked to see if the bolt was going back far enough by holding the bottom of the bolt release in and the bolt did lock back after each shot. The other difference is I left the standard carbine buffer in place which for me is good since I didn't have to go switching the buffer out when I switched the upper. I think I'll try the Unique powder first -- if I can find it locally.
Loaded some rounds and the Unique powder did make a bit of a difference in allowing the bullets to be seated deeper in the cartridge case. In the picture below the 50gr bullet is on the left and the 40gr bullet is on the right.
The only problem I see is the loads seem to be kinda light. These rounds all load in the PPS magazine just fine. Now I went a bit hotter on the powder charge with the final test being 5.5gr of Unique under the 50gr bullet with a COL of 1.38" and it still seemed kinda mild plus I think the bullet was right on the powder. I have no idea what the velocity is. I have the feeling that this would make a nice plinker round but nothing like a .224 BOZ whatever. If another magazine could be found that allowed for a much longer COL this would be a really cool round.

OK, this is step #2. I figured I would try setting the sabot out in at a more normal length. This means I can't use the PPS mags but I think I can use the 20 round Pmag.
With the sabot set out further I have a heck of a lot more powder room. the picture below show what I think is the longest I can make the bullet with the sabot -- it's 1.60" long and the base of the sabot is right at the base of the shoulder. I put a slight crimp in the neck to make sure the sabot doesn't shift when being loaded in my carbine.
I figured that since this is a light bullet (50gr + the sabot), the powders I'll try are either Lil' Gun or H110 -- maybe even try more #9. I'm going to switch from the blowback Tok carbine to one of DI operated Tok carbines.

Ok, this looks like it will work if I can just get the right powder. the picture below shows the 50gr bullet in a sabot on the left and a 35gr V-max in a sabot on the right. Notice the height of the sabot on the right -- that's how much more room there is in the case. I loaded it with 10.0 grains of AA#9 and it shot really good!
Both rounds are the right length for the PPS mag which is a real plus. I need to find a quicker powder with more density -- something like Power Pistol or even AA#2.
