Thats what I do also. Pull trigger while pushing bolt forward and lock in to place.
A luckily humorous aside:
An old neighbor of mine, famous for a few of his mistakes, advised his sons that doing so with a centerfire rifle and cartridge in the chamber would render the arm safe for an essentially drive around road hunt for elk. Kid did not quite get the exercise synchronized and managed to light off a 300 Win Mag inside the Surburban with the muzzle resting on the floorboard.
Other than he and the two boys not hearing much for 3 days the damage was minimal. Seems the slug went through a rubber drain plug in the floor missing the tranny and all other vital components.
Regardless of synchronization issues, it's not a safe practice, as ones firing pin is now resting on a live primer. A tap from the rear could easily light things off.
Despite manufacturer suggestions, I do not dry fire my rimfires. I don't even load my Ruger magazines in the squirrel fields, as I'll lose count and fire on an empty chamber. I load and shoot in single shot mode.
One can disassemble his bolt and assess firing pin travel in a 77/22. My Rugers and an Anschutz firing pin will not contact the barrel face. I've not broken down my CZ457 bolt yet.
