The . 223 is best put to use on coyote, groundhogs, and other pests.
Why is match ammo hollow point?
While the sharper point of the secant ogive may have appeal, the tangent point maximizes bearing surface, critical to accuracy. For this reason, most hollow point match bullets have tangent ogive points. Hollow-point match rifle bullets have a very small opening in the nose.
Do police use FMJ or hollow point?
More types of 9mm ammo exist than just FMJ or Hollow Point. Most police officers now use Hollow Point rounds, because when you shoot somebody it fragments and splits up inside them and is less likely to exit and harm an innocent bystander.
