I hunt in PA, and would like something with some knock down power. I sold a 30-30 which treated me well, but didnt have the knock down power I was looking for. I hunt all state game lands, so dont want the deer going far as people are always close by. One year I got a good shot on a deer with my 30-30 and it ran about 150 yrd. I heard a shot down the mountain, and another hunter claimed it. Already gutted and dragging by the time i got down there. So.... I want something with knock down power. Im thinking of a rem 760 pump in a 30-06. What do you guys think I should go with? I want to shoot accuratly as possable. I dont do alot of long range shooting, but some places I go I may have to shoot 100+ yrds. But most of the time it should be under 100 yrds. Hunt whitetail. Are there any differences between a 30-06 and a 308? Or are they basicly the same? Im looking to spend about $400. Consistant accuracy/knock down power is my main concern.

Thanks
