i too would start off at 90 and work your way up.
I use CCI 209 Magnums, the TC's though i hear are cleaner using the Winchester W209 primers.
Carry an 1/8" drill bit with you as well and clean the flash channel out after 3 shots. That 1/8" channel gets clogged up pretty quickly with carbon so its important to keep it clean.
