RE: .243 for deer
I talked to two guys in the last week that use .243s. One popped a six-pointer in the Adirondacks of NY, the other is an apple farmer in Columbia County of NY that uses his .243 for "pest control"--he's got two in the freezer right now. Both say that it drops them like they've been hit with mallets.
It's all where you put the bullet . . .
