Depending on their blades' length and engine rpm, the tips easily can be in the transonic range, if not supersonic.
Both the BB Sniper load and the NATO MII8 LR use the 175-grain Sierra Boat-tail bullet the loading coming into favor because velocities remain above the de-stabilizing transonic range at 1,000 yards.
The same barrel was used with the same powerplant to test four different pellets--each shot at four different average velocities in a test I thought would prove once and for all that pellets have to go slower than the transonic range to be accurate.
This configuration enabled it to fly through the transonic range for relatively long flights.
