Caliber is caliber, being a youth rifle has nothing to with how the load will perform. Unless it has an unusually short barrel.

A youth model is simply a rifle with a shorter length of pull and maybe less weight so the rifle is easier to handle for a smaller person. If the youth model guns feel short to you, get a full sized rifle. Age has nothing to do with it. I am almost 40 and like youth model guns because I am short. They just fit me better. But I know 14 year olds that are too big to shoot a youth model.

The performance should be exactly the same, it just effects how the gun feels when shouldered.
