No dump hunting but I am a country boy and we got to shot barnrats!
it was my best friends place and if we had helped out with chores and stuff we got a bag of 22s and if we had been really workin we got a bag of 38s to a snubbie used to kill the cattle, very short, only a single shot but helluva fun times.
If we ran out of bullets we got my mates grandmas Jack Russel terrier and let him get the rats, the ones that got away from that monster met our pitchforks. Had so many rats that I actually think that one of their cats ate himself to death, the cat was huuuuge, named Fat Nick
mean old cat to, got into a fight with a grown lynx and was badly mauled but survived, that is until he ate himself to death
