So they cost 2 bucks each ? Who cares ? Not for hunting woodchucks. Check sight in and kill animal --- 5 rounds.
w/ a $0.22 bullet (currently $0.44) like the Speer GS, it allows one to work up good loads, shoot a lot, and Then go out and kill game w/ it.
Just know the performance envelope, as it is a little smaller then the NP.
