I've owned 3 rifles in 35 Remington and still have two. I've carried them hunting a fair amount and have taken 4 deer with them. A solid hit and they fold in their tracks. I've actually had a doe run farther after a hit from my 35 Whelen. I can't speak about the 30-30 Win for hunting because I've never owned one. Back when I stocked up 30-30 ammo was $20 per box, and 35 Rem ammo was $28 per box. I've seen it lately for sale for closer to $50 per box, but that's not a deal breaker for a good box of shells. If the difference in this cost empties your wallet I'd be finding another means of employment.
