Ive shot some deer with the 24 and 25 caliber guns, but I prefer something a little heavier. Like something that will shoot 150gr or heavier bullets. If you can afford it, I think you would be happier with a varmint rifle and a deer rifle. If not, the rem. 700 varmint is a good one, the m70 and savage too. I'm not sure if they come in 2506 or not, but you can shoot varmints with 7mm's and .308's too. A 7/08 with 120 gr ballistic tips should splatter a woodchuck just fine. Just my thoughts, I would buy something big enough for the deer and make do on the woodchucks with light bullets. Or maybe buy one gun and two scopes, one like a straight 12x for varmints, and a 4x or something for big game. Have fun.
