Yes, Yes, and Yes. I use it mostly with target grade ammunition to turn it into sure shot squirrel killers. ALL of US squirrel hunters strive for head shots for a quick positive kill but sometimes that shot doesn't present itself. With that sub-sonic target ammo "Nasty Nosed" a body shot is just as good. I have killed coons and opossum cleanly with the same Acurzr worked ammo. I have a customized 10/22, a CZ 452 and a 14 inch Match BullBerry Contender of the three the CZ shows the most improvement but all three show some.
