Keep in mind some of the naysayers here also will say that practicing with a .223 trainer is fine and then just shoot your 6mm or 6.5 a little before the hunt. 
I see nothing wrong with honing your skills with lesser recoiling, less expensive ammo. Then using your big boy before season a bit. Once you have the processes of shooting at range, it transfers from cartridge to cartridge.
I personally think if you can use a brake, or a can, or can handle the recoil, get whichever you want. I went with the 300 win mag myself - 1/10". I can find plenty of factory ammo for it. Federal and hornady both load a 200 gr eld-x for it. I also hear tell it will shoot handloaded 215 bergers, if you load.
The 300 prc will have a harder time with lighter bullets if you want to use them...but high bc factory stuff is it's bread and butter.
Nothing wrong with a big 30....if you want just a bit less recoil go 7mm prc or 7 mag.
Just MHO....
