lmao, playa you certainly started a classical funny with this one. The 30/30 kills deer, no doubt there. But equally so does a 22, its where you put the bullet. Now if you were a small squat and or didnt have a rifle I would say ok. But if you have a 7mag, why waste your time and money on an ancient thing like the ol " tutty tutty" ? If you had a Camaro in your driveway, would you carry your moms Corolla on a date?
The 7mag will hammer deer at 50 yds as easily as any 30-30. Yet it will likewise smoke em at 300yds (I know, I' ve dropped em in their tracks at 300 with my 7mag) and with the 30-30 all you can do is sit there with your thumb up your butt and wish you had your 7.
The 30-30 WAS great in its day. But then again so was the original 45/70 blackpowder load. Like anything else, times change and better things come down the pike. Steam locomotives once ruled. But now with the 7 you have a diesel/electric loco and can " crank it on up" .(LOL now with the supermags, I prefer a japanese bullet train!)
I have the 30-30s bigger brother, a 35 Marlin 336. It was handed down to me by my grandfather (rest his soul) and it will likewise go to my first grandson. I carried it out and killed with it once " just because" . I likely will let my boys use it in the future as well, but its more out of novelty than from its sheer effectiveness. My sons first " deer rifle" will be a 243 700ADL Youth. Even that lil popshooter is more effective than the ole " saddle guns" from the 1800s.

DROP EM WHERE THEY STAND!
