I'm not a fan of typical 30-30 lever guns for kids/wives/new shooters. As others have noted they are HEAVY. Many are quite easy to reload and not ease the hammer down thus a safety issue. I DO like a 30-30 bolt gun for new hunters if you can find one. The 99's are a bit pricey these days.
I'd concur with many who would opt for a youth or ltw bolt as many have special stocks now and the stock can be replaced when needed.
I have found the 243's have more bark and I prefer a bit more bullet on game so I'm in the group suggesting 260, 7/08 and even 308 (anything in that caliber range). If you do not hand load the reduced recoil ammo is available and more than adequate in killing power.
Lots of options these days in youth compatible rifles so shopping should be great fun!
