Youth elk rifle?

[3006Sprng]

My daughter has a Tikka 243. My son will also be hunting this fall. I'll need another youth rifle. I'm thinking my daughter will be ready to bump up (slightly). And my son can take over the 243. I'm looking really hard at a 7mm-08. There's obviously a lot of other options. My budget is under $1k with optics. Thoughts or suggestions?

Savage 110 hunter, adjustable LOP and comb height. 7mm-08 for sure.
