you must decide that for yourself by what you shoot best, you also have to take your hunting area in consideration. If you are hunting in the woods where there is some thick brush then 30-30 all the way. but if you are hunting over an open food plot or grain field where you are often met with 200 or greater yard shots,the .270 will definately hold better in that situation. I have always used a .270 but I rarley rifle hunt in the woods
