The reason I ask is I'm working on some different rounds. I made up some that will work in the PPS-43 magazine and some long ones that I made a special 30 M1 carbine magazine setup for. I first started in an old blowback AR Tok carbine I had and then decided to go to my DI operated Tok carbine when I did the M1 Carbine magazine thing since there was no ejector built into that. The DI Tok carbine functions like a champ with the Sabots without having to change anything like springs or buffer weights.
The picture below is of the two different types of rounds. The shorter ones on the left use 35gr Hornady bullets and 11.o grains of AA#9 and an over-all length of 1.36" -- they fit in the PPS magazines just fine. The rounds on the right use 55gr Sierra spire points and 11.3 grains of AA#9 with an over-all length of 1.57".
The picture below is of the M1 carbine magazine and adapter with a Sabot round in place. The bullet in that Sabot is an older type I was testing with -- a 50 grain Hornady moly V-max that is actually a longer bullet than the 55 grain Sierra spire point.
Loading these sabots takes a little extra work so they go in straight and don't get the plastic shaved. I've fired many rounds for function testing in the DI Tok AR but have not had a chance to get to the range to check if I can get any accuracy out of them. I was just wondering if any body here might have also tried the Sabots?
