I’m confused on all this timing talk, it all looks normal to me
The bolt handle is supposed to contact the angled extraction cam ramp on the receiver right before the bolt recoil lugs disengage from the receiver recoil abutments (the abutments also have an angled ramp on the edge). The bolt handle then rides up the receiver extraction cam as it is being lifted which gives mechanical assistance for the bolt to extract the fired case from the chamber. When the bolt is all the way up the case should be dislodged from the chamber and when cycled rearward there is no resistance.
Without the assistance from the extraction cam on bolt lift, the shooter has to pull hard to the rear on the bolt handle to get a fired case dislodged from the chamber.
