well i don't know. i have a pump-up .177 and .22 which both can kill starlings at 50 yards and hit targets and both are from 1975 and still shoot. what do you want to hunt? birds, rats, bever, nutra, rabbits and are you looking for power or long range? the best i can think of for 150 or less are  850 Carbine by Gamo,  BENJAMIN 397,  CROSMAN 1077,  CROSMAN 2100B 
  CROSMAN 2250B , PHANTOM 1000 by Crosman ,QUEST 1000X, daisy 1000 and in .22cal daisy 22 SG, and  BENJAMIN 392 . as far as handguns most are not good for hunting but there is a few the  CROSMAN 1377C  and the  BENJAMIN HB22  these are the only to that can be scoped and how the power to hunt with.
