There is an old saying, practice with what you are going to use in the field, and I agree with this. When I was a late teenager I used to shoot over 10,000 rounds of CF rifle a year from 3 or 4 different calibers but all were Rem 700 BDL's with very similar velocities and trajectories. Most of the shooting was with my 243 which I loved, but when I grabbed the 264 or 7 mag the feel was identical and they shot to the same place right out to 400 mtrs. The triggers were all adjusted exactly the same and all held similar glass. It really did allow me to practice endlessly with a light recoiling rifle and yet have that practice transfer meaningfully to the other larger caliber rifles in my cabinet. This was recommended to me by a fellow back then and I believe it worked and still recommend it today some 40 years later.
Firearm familiarity is more important than caliber, in my opinion, as long as the cartridges used have similar down range ballistics, all practice is good.
