I've got a nephew that uses a Rem pump in .270 and he is deadly with it. I wouldn't want to be a deer. elk or pronghorn around him when the season is open and he has a tag in his pocket.
I shot against a kid (20 years old) like that. He was damn good with that pump gun. Good offhand shot. Nailed an egg in an offhand shoot and damn near walked away with all the money... I did say damn near....
