So lets sum this up:

the OP is going to take a "position" not a job

he is planning on getting a 35 whelen, clearly inferior to the CZ 9.3x62 he could buy for about the same money.(he already owns a CZ, so no learning curve)

if he MUST have a whelen, he is doing it the hardest way possible by reboring something else, is spite of no shortage of factory CRF 35 whelens for sale

now, because all 35 whelen factory ammo is inferior to that available for the 9.3x62, he's thinking about reloading

can hardly wait until we move on to a scope for the rifle.
