I've killed most of my deer with my Marlin (but my .270 is catching up.)
No doubt the Leverevolutions are good. I haven't used them, but If your really need the extra range I'm sure they are great. In the woods, in a climber the Marlin is terrific. All my shots are always close. One great thing about the 30/30 is the lower velocity which allows close range shooting without worrying about how the bullet will perform. You don't need anything real fancy. Just find the least expensive off the shelf that shoots the best out of your rifle. I have never worried about them doing their job on deer. The best off the shelf for my rifle has been the 150 or sometimes 170 grain Winchester power points. I've played around and reloaded Speer 150 gr. soft points, but I am not gaining much over the off the shelf. Most of my reloading time is done with the .270. If I hunted up north were the deer are bigger I would go 170gr.
