If she is under your watchful eye a 105 HPBT, 95 BT, 100 Partition would all work in my opinion and have shot well in 10 twists. The 95 grain Ballistic Tip is a tough bullet with decent aero. The 105 Hornady ain’t bad either. If it’s a 243 you want I’d try it out and see how she handles it. Lots you can do with it if you end up hating it and wanna set it up for something else.
I got my daughter a 7-08 Tikka Compact and it’s wonderful with 120 Ballistic Tips at 2500, so that is another option. Lots of elk killed with 30-30’s and both cartridges I mentioned have more juice for further out than the old 30 WCF does.
