The sabots come in bags of 1000 [more than any sane person would ever use], but I don't know where I bought mine over 10 years ago.
Seating the bullets into the sabots straight is critical, and will require a bit of ingenuity.
Best luck will come with heavier bullets [this ussually helps with accuracy too].
A deep chamfer in the neck will be necessary to avoid twisting the sabot when seating.
The hardest part will be getting perfectly concentric loading.
After buying half a dozen different powders to try, and 8 to 10 different boxes of bullets, and spending hours attempting to get everything perfect on your loading, then you get to go to the range.
You get excited when you hear your gun go POP, but very discouraged, not see anything hitting the target [or extremely large groups].
Gee, looking back over this it reminds me of perfecting a load for any other new rifle, just multiply time and materials by a factor of 10, and you might be ready to shoot something!
I believe sabots are better suited to larger bores where there is more margin for error, and less pinpoint accuracy is expected!
If you want to shoot a 22 caliber bullet----use a 22 caliber barrel, you won't be disappointed.
If you want to shoot a 30 caliber barrel----use a 30 caliber bullet, you won't be disappointed.
If accelorators lived up to how they look on paper, they would be on the shelves of every sporting goods store around!
I don't regret what I did, I just would not do it again. What I spent trying would have half paid for a new rifle!
