Lever action guns are probably my favorite long guns, I have (have access to my old man's that is) a marlin 1894 rancher in .44mag and a .30-06 Ruger Mark II M-77 standard, to name a few deer rifles, I almost always use the .30-06 because it's glassed, and has a bipod. On drives or stalks, I much prefer to take the lever action though, because it is MUCH lighter, open sighted, and more compact, which leads to a hundred other good things: faster to shoulder handling, faster swinging/readjusting, faster target acquisition, faster action cycles, and just a lot more fun to shoot anyway. I carry it on drives as an option to my SKS a lot, and I absolutely love it.
Granted, it's not as accurate as either of those mentioned, and it doesn't cycle faster than my SKS <img src=icon_smile_wink.gif border=0 align=middle> and it might really be a toss up between it and my .30-06 on speed, maybe it just feels that way, but it's no slouch, especially for a .44 mag, and it hits hard with the hot loads I pack in it.
Since you said it's a "new rifle", I'm assuming you have a bolt already, so I'd say GET A LEVER!!! If you don't have a bolt, then get the bolt, every boy should have one of each, but the bolt first!!!!
BTW, don't get a .30-30, get a big bore, like a .44mag, .45-70, .444, .450, .44-40, they'll give you a lot more security with practically the same if not better trajectory ability.
Screw the 10 ring, keep them in the zero!!!
