Savage Axis, granddaughter is 5’2. She has a youth model, she has been shooting it since she was 11
This, too. When my son was 10, I got him a Savage youth model in 243. Later (he's 6'2" now) switched barrels to a 308 and bought a 2nd hand full sized stock.
Swapping barrels on a Savage is easy. However, with a 243, and on a youth stock, she should be good to go for life.
