I have shot groundhogs with a 7MM-08, 257 Roberts, 308Win, 250-3000, 6MM Rem, 6.5x55, they are all very fun calibers to use, I love rifles, and since groundhogs, crows, coyotes etc offer me my only chance to use my various rifles on game here in Ohio, the 257, 250-3000, and 6MM are pretty much on par with the 243 ballisticly, I say whatever floats your boat as long as its safe and legal, I mean I dont think the groundhogs will be able to tell the difference in being shot with a 22LR or a 300Win

they will be in that big bean field in the sky
