The sabots are usually around 50 to 75 feet from muzzle, much like the muzzle loader sabots. Occasionally will fly off at up to 45deg. angle from line of fire.
I shot some of the Remington's several years back, too. Mine chrono'd at 3,955 from a 24" Interarms Mk-X . Accuracy was not up to hope's at around 2-3" at 100yds. This rifle in .30-'06 was good for 1/2" with 168gr. Sierra BTHP and 56.5gr of IMR-4350. It's now a slightly less accurate, but substantially heavier-hitting .338/06. (.75-1.25" w/200 Hornady-SP over 54.0gr of Re-15 or 61.0gr of H414 for 2,830fps- 3,550ft/lbs)
The Rem. sabots were mildly popular for poaching deer at night in my neck of the woods in the early '80's. All you had to do was after finding the dead deer was to figure out generally where the shot came from and a good search dog would quickly find the sabot.
Hence, -not good for nefarious use.
