I have found many of the High-powered air guns are Alot louder than a .22 long rifle hyper-v round,the airguns are usually heavier,Forget about a follow-up shot that just ain't gonna happen!On the otherhand,living in a place where firearms can get your freedom revoked,I would look for a Benjamin pump action in .177,As that caliber has more variable types of ammo & higher muzzle velocity as well.I mention Benjamin because I've had mine for 40+ yrs & it still shoots fly's off the wall at 20 paces,It's the AK of airguns IMHO,my 10/22 Ruger is lighter with a 10rd mag,it shoots fly's off the wall at 50 paces,heck!,it shoots thru a wall if I need it to!
