Projectiles must have some kinds of internal guidance system (that works at Mach7) or else the Navy is just going to be slamming random meteorites down anywhere within very large swaths of countryside.

Regarding planetary contamination, with the amount of meteorites hitting ocean I do not think we have anything to worry about.

Most small meteorites are still cold in their interiors when they land.

Bacteria could have been transported between planets by traveling on meteorites.

Send out lots of meteorites with bacteria on them.

The shape is typical of meteorites – a fresh fracture surface on one side, while the other side is rounded,” said geologist Hans Amundsen.

(admittedly about spacecraft rather than meteorites): "Through making the reentry vehicle blunt, air cannot 'get out of the way' quickly enough, and acts as an air cushion to push the shock wave and heated shock layer forward (away from the vehicle).
