NOT a paper/bullet problem.

gun is nested under the rigidbody ship.

gun is above the hull in world space.

gun fires the projectile.

projectile.myRigidbody.AddRelativeForce(impulseVector, ForceMode.VelocityChange);

velocity is 760 m/s

The projectile collides with the ship hull.
The contact positions are 15 units away from the hull collider.

If discrete, it does NOT collide with the hull.

“Note that continuous collision detection is intended as a safety net to catch collisions in cases where objects would otherwise pass through each other, but will not deliver physically accurate collision results”

your best option is to use a raycast for calculating where the object would collide
