We're assuming you're deccelerating by way of ion/plasma thruster (some half of
payload for reaction mass) until you hit the upper atmosphere or you've
fired into an initial aerobraking corridor resulting in a decaying
richochette trajectory of a self-guiding ceramics foam coated metal
payload from a linear motor on the Moon.
You don't have to worry about canned monkeys or even finicky payload,
so you can hit 100-300 g decceleration with no problem. This will make
plenty of nice pyrotechnics, if seen from the ground.
Once you're no longer in a plasma sheath and gliding you can can
have a controlled glide halfway around the world, to delivery precision
would be ICBM-grade.
However, I'm questioning the whole basic assumptions of Sqrat
spaceflight (gather *all* the nuts and drag them home). A more
advanced Sqrat would set up nests where all the nuts are.
