" OOH, that is one more thing to check, make sure that in cycling the bolt it always comes back far enough to catch the trigger sear."

That one was a red herring, pulling the cocking piece far enough back to catch the sear is automatic during the lifting the bolt handle. Short cycling the bolt will cause no harm unless you do not pull it back far enough to catch the next shell.
I tried some other things like rotating the bolt sleeve while the bolt is pulled back, impossible the Krag inventors and armory really nailed this design.
