Well a friend at work is going to bring his .308 so I can try it out. Basically gonna fire a round to see if I like the feel and kick. There was a .308 up there but I figured at the time it would be a bit of overkill. He has taken 8 deer with the gun and says he likes the power behind it. One was a doe through brush. He could see the rear end of the deer and aimed for the kill zone. The bullet went through the brush and dropped the deer right there. Hard to argue with that.
But if I had to say a second choice it would be the .270 or 30 06.
