which is true for a shotgun but not for a rifle or a handgun?
a shotgun shell does not use a primer.
a shotgun has lands and grooves in the barrel.
the projectiles are pellets.
shotguns do not have firing pins.

Explanation:

For the first question, a shotgun can create a widespread dispersal pattern of small - sized (less than 1.0 mm diameter) elongated bloodstains with a void at the point of origin due to the nature of its shot spread. For the second question, shotguns fire multiple pellets as projectiles, which is not true for rifles or handguns that typically fire a single bullet.

Answer:

Question 23: shotgun
Question 24: The projectiles are pellets.
