Hi all, I have a question, if there's a round chambered what is the ideal or allowable gap between the cartridge and the bolt head face? Just looking for a a simple way to explain all this stuff.

Quoted headspace of 0.064" - 0.074" is without the cartridge, 303 cartridge rim thicknesses vary but are normally around the 0.059" - 0.060" so the 'gap' (as in your question) can be 0.003" - 0.014"
Tighter is better (as they say)
