One piece of advice… make sure that you are still practicing dry firing and working the bolt with the centerfire. I work with lots of new/young/inexperienced shooters, and short-stroking the bolt is a real problem in the heat of the moment if they have been practicing with a rimfire.
Rimfires are great for cheap, low-recoil, low noise practice and plinking, and I’d recommend having most shooting be done with them. I no longer own a bolt action rimfire (I plan to fix that transgression sometime in the future), but I have kids to practice “working the bolt” between shots to get ready for the real deal, then I have them to end the shooting session with dry firing and working the bolt on the centerfire (running it all the way to the stop at the back) in real-world field positions.
