My strong preference is for bolt rifles. Except my 336 in .35 Rem. That's my "go to" rifle for most deer hunting inside 150-175 yards. There is little effective difference between the .30-30 and .35 trajectories and either will do the job on deer quite well, all advertising hype aside.
It's always been amusing to hear some "expert" drone that a 300 mag of some sort is an effective killer at 400 yards but a .30-30/.35 isn't, even tho the impact velocities at 400 on the one hand and at 150 on the other may give the old round's an advantage at the closer distance. It's the bullet that does the job, not the case, and I get few shots beyond 90 yards anyway.
So, my beloved -06 and the .243 usually sit in the safe while I hunt with the Marlin. I'd suggest you get the lever gun and mount a low power variabale scope on it, in low mounts/rings, not those god awful "turkey neck, see-thru" mounts. Or put peep sights on it and leave the small target shooting apature disc at home.
Bore sighting a scope should be free, it only gets you started fowards a zero and even then it frequently doesn't work very well. Just set your first target at 15 yards or so and get a coarse zero on that, then go a longer distance for final tweaking.
